Reviews 10 He had seen several sylvania light guide versions of annular Adapters studio and had it on my list of bricolajes sylvania light guide until a couple of weeks I decided to do so ago. The truth is that no studio usually do, what I really like is messing with scrap materials and cheap stuff from the bazaars or Ikea. At first I bought an Ikea lamp for 9.95 Euros to manufacture the ring, but then I realized I had too much background, so momentarily abandoned the project. Another day, I went to buy duct tape to a bazaar and found a biscuit mixture of aluminum and glass sheet for puddings that I would come in handy, sylvania light guide and all for less than five Euros ribbon included. So I strew all over the table and got down to work. First of all I want to warn you that we will work to cut metals and edged left on a sheet after cutting with scissors are like a knife, I tell you from experience, usad work gloves at all times and limad well edges when you corteis the plate. The first thing I did was cut the nipple of the biscuit mixture, which is very close to fit a goal, and cut the ass vessel flan to the same extent that the gap left in the biscuit mixture. Thus the light will be reflected in the glass inward, which will better distribute light throughout the entire ring. On one side of the biscuit mixture I cut a hole the size of the flash head and made a tab with tin for the flash to enter comfortably. To paste the glass and tin tab to the biscuit mixture I used white silicone which also serves to plug the holes and uneven areas. While the set was drying I started making support for the flash, is nothing more than a piece of iron platen cut to size and folded in an "L" with two holes, one for tapping into the camera and other threading the flash. I forgot to mention earlier that this system not need a flash extension cable. As my friends accuse me rightly being a bungling and leave the work half, this time I decided to give it a semi-professional finish with a lick of paint, are actually a couple of handyman with a spray paint matte black and the truth is that the finish sylvania light guide has nothing to do. You may ask what that right there, what is ...? Well as I left over a lamp and I could not change it, I began to spin to see what I could do with it and I decided to make a reflector for a second studio flash. In this case the light comes from the back, and took advantage of the hole socket we'll just zoom in a little and put a tin tab to securely sylvania light guide hold the flash head. For the reflector must make a smooth hemisphere, it is a piece of cork ball, I used an old garden lamp having top of that. We covered well the hemisphere on the outside with aluminum tape to reflect the light and joined the lamp with three wire rods. See to it that the hemisphere is not so large that it covers all the light nor so small that miss the direct light from the flash, and is located at an ideal distance roughly. Paste the rods and flange silicone tin and tuneamos a bit to give a less seedy looking. Returning to the ring adapter, which is the undisputed star of this post, and to let it finished, we must add a diffuser to better distribute the light. It is best to use a translucent plastic that is cheap, weighs, is handled very well and is an excellent diffuser. In the next picture and you can see the finished and ready to use gadget. Despite apparently cumbersome, actually it is, but not as much as it is very light and handy, can be held traditionally hand lens or also by holding the flash, that is in taste. The last thing to do is a series of tests to see how it gives light. Clearly a homemade solution that is not going to provide the same light as a ring flash studio professional, but also costs the same and to play around or do some eventual picture I think it gives a more than acceptable results. The thing to remember is that, despite using the latest technologies in terms of reflective materials is concerned, loses enough light on the way, so you have to compensate flash output so that the pictures sylvania light guide come out with correct and do not use very long focal closed or diaphragms exposure. Best as always do some testing and see what values are most suitable. I leave Annularity proof so you can see that the light is fairly well distributed sylvania light guide throughout the hoop. Well, that's it, you

It remains to prove that insects or small bugs pose for photographs. Sometimes nothing awakening or when they are eating is possible retratarles with some time to prepare, but usually is not the case and count with fewer opportunities. To this we add that in macro photography, work most of the time at extremely close distances and targeted 90 or more millimeters, as in my case with the Tamron SP 90mm F / 2.8 Di VC USD 1: 1. This means we have to make do with very small depths of field and very critical approaches. After reading some manuals for macro photography, I decided to follow the advice and dotarme an external lighting to freeze motion and provide a uniform led flashing lights with few visible shadows in photography lighting. When the subject is very close to the camera, led flashing lights the distance between the flash and the optical axis becomes led flashing lights significant. For objects close to the camera, the size of the ring flash is important led flashing lights because the light hits the subject from many angles, similar to what is achieved with a conventional flash and a good diffuser. As its name suggests, the flash ring (Ring Flash) is ring-shaped and designed to fit around the lens. The flash itself is mounted to the lens and the power cord is connected to the output of the camera so that draws power from the battery. led flashing lights The ring flash used in macro photography usually have insufficient for use in normal light photography, especially if they are of a more than affordable price as the one I chose. The ring flash for macro photography usually has two parts: The first with a shoe that is installed on the output for external camera led flashing lights flash, and the second, a flash unit which is mounted on the lens. Power is supplied by batteries located in the first unit, which is connected to the ring or ring flash by flash cable. In fashion photography or portraits can also use ring flash, but these are mostly larger and more powerful and more expensive than here I bring. As on other occasions and always bound by the same economic circumstances, the possibilities lead me to choose a ring flash affordable led flashing lights price and of sufficient quality for macro photography. For more than twenty euros in aliexpress.com led flashing lights have decided to become the Meike FC-100, a ring flash specially designed for the foreground type. Not a flash for macro pro, but its light weight and conditions come me well for introducing me to the world of macro photography and also can be used as full or partial flash on your left or right depending on the lighting situation . Meike FC100 Specifications Led Macro Ring Flash Type: Electronics Brand: Meike Model: FC-100 Weight: 168 g without batteries flash - 0.71 lbs Body Size: 191X77X60mm Base: 114X114X22 power supply 4 AALámparas batteries: 32 pieces of high brightness leds Number Shooting: 100-800 led flashing lights times (using AA alkaline batteries) Range: led flashing lights 5cm to 150cm Recharge Time About 3 seconds (using AA alkaline batteries) Color: 3200-5500K Exposure time: 1/100 sec Power setting: 1 / 64, 1/32, 1/16, 1/8, 1/4, 1/2, 1/1 modes: light mode, flash mode, L (left middle part of the ring flash), R mode ( middle right) part. Compatible with: Canon, Nikon, Sony ... Package includes: Flash, Base ring mounting shoe. Seven adapter rings 52, 55, 58, 62, 67, 72 and 77mm for use with virtually any type of lens. In my case, the Tamron SP 90mm with F / 2.8 Di VC USD 1: 1 58mm ring as you can see in the pictures is necessary. Manual in Chinese and English. Warranty card (in Chinese). For just over 20 not expect a sturdy, solid and professional led flashing lights flash. Everything is plastic and have to be careful not to hit him, but is very light and it comes in handy when having to install it at the end of the lens. On the other hand, has the possibility of continuous light mode and flash mode. While cancel the flash is subject to ring placed on the thread of our goal, this is enough slack so that we can turn our hand and thus modify the light from left, right and turning led flashing lights to play with light and reflections the object to be photographed. The assembly of the shoe is made of metal and necessarily robust to be well attached to the body of our camera. Just a link, so it lacks any kind of automatic measurement with the camera, only the flashing to warn the preparation for shooting. The unit requires 4 AA batteries and you have also asked on aliexpress sufficiently powerful rechargeable and a charger.

My problem is that many times, if I have the flash on, the lens motor starts working "on your own" oyndose the typical noise USM, but at that moment I is trying to focus, dejndome the camera inoperable conditions in a few seconds despusy always trying to take focus on a well-lit area and regained control, I get focus and the problem disappears.

Have always struck me the ring flash for its ability to give good light without shadows in portraits. However, its smaller circulation makes out much more expensive than their normal counterparts price is amortized worse than a normal flash, to which habitually adds more volume. In short, it is an ideal for portraits element, but with little predicament by his younger versatility. Most professional brands have it, but a couple of years this market semi-virgin activated significantly ago. The first to take the plunge ring were flashes of hits, that is, that in exchange for a very affordable price what you get is a reflective housing to adapt to your usual flash. Removed electronics, obviously the price drops significantly. All advanced amateur creative t12 can allow Orbis or Ray Flash. And this has come Metz and given a return to the topic with their new Mecablitz 15 MS-1 digital. We were able to test the toy and we liked: the idea is to have a ring flash small, lightweight, comfortable and sync wirelessly. creative t12 Ideal for portraits and close-ups - that is, to what actually use the vast majority of the market. The Pros that have attracted my attention: It's a real flash, and not a mere adapter. Its small size and light weight are perfect and do longer fit to carry in your backpack anywhere. Orbis compared, no color or size or the flash ring concept. Operates on two AAA batteries, which guarantees affordable energy anywhere. Wireless TTL for those cameras that support it. Metz speaks on terms or other of Canon, Nikon, Fujifilm, Olympus, Panasonic, Leica and Sony Alpha. What I can use slave flash. The Cons, according to which eye looks: Bring three adapters rings 52, 55 and 58 mm. Although his record says you can buy rings 62, 67 and 72 mm, me not convinced for my Nikkor 2.8. In fact, even without the ring I could not fit in the 24-70 or the 70-200 because they are 77. I think in this self-excluded are an interesting niche. The manual is somewhat cumbersome, or am I stupid this month - which can also be ... The operation itself creative t12 is simple (once you manage to synchronize with the camera) and light it gives is more than acceptable in the range of use for which the device is intended. Once mounted, is much more comfortable than the alternative ring prosthesis: an all-in-one compact creative t12 camera with a voluminous + flash + adapter. And of course, have already given some other prize. However, it is an outstanding choice for those who want to buy a good flash ring true without breaking, as it costs less than 300 (thanks Ferguson, Zaer!). What you'll be using a lot more than you think. BONUS WTF: The box clearly announces that it is a perfect flash for digital. A Either Metz has generated "digital light" or someone has to talk seriously with the Product Manager Product. Or am I stupid this month - which can also be. True, the price issue I think it deserves an important place in the post, to position the product. Over there I saw about 300 . The bonus "perfect creative t12 for digital" is good, still think that all that carries the word "DIGITAL" seems better. I bought almost go out and macro is just extraordinary because, creative t12 as in portrait, no shadows, takes time to get used to the many configurations as you can change the power of each of the two lamps and can also modify the angle each with three separate positions. Do all manufacturers trbajan the same voltage? It sounds to me that there is no standard about it, but knowing the marketiniana mind, his argument would be more along the line of "this light parseks transcopuliza ions emitted light to improve digital CCD disrrupción ... bla bla bla " creative t12 To me it makes sense voltage; because there are plenty of flashes designed for "analog" cameras, creative t12 which today are still made that NO can be used in digital cameras (directly burn), and in issues of "Cheap flashes" always have to tread very aware they are the admitted voltage to digital. Do not say nothing of power. I use a Chinese brand (I can not remember) and it is a contraption, creative t12 with its battery box weighing about 3 bricks, but sticking to grab some flashes (models complain deque stay awhile with hoop light on the retina). But my problem is that sometimes, especially creative t12 when shooting backlit against one, or from some disntancia, I need more power. Sounds to me like this flash must be excellent for short distnacias, but with 2 AA batteries do not think it serves more than two meters, or at high brightness ... What say that l

GTMax: Ring Flash LED - ALTFoto Follow hypertext The flashes are one of the most expensive investments photographer, apart from a good lens. A flash brand may cost a few dollars and pocket the buyer maul, but also the use of light outside the camera is a big learning and that all photographers should try just beginning. The LED technology seems to come to replace octopod traditional forms of lighting, octopod promising the same intensity at a lower price, with an expectation of much longer life. With this premise, GTMax manufacturers decided to apply in the area of camera flashes. Specifically it is the GTMax Macro Ring Flash LED Light that for scarce $ 29.99 provides light outside the traditional internal flash of the camera and also makes annular, with all the benefits that entails. It is compatible with most cameras and current manufacturers and has a built 6 adapters in different sizes, to fit perfectly with the lens you use. Its effective octopod range is 3-100 cm, so it is addressed to the macro or close-up portraits. Like any new technology, there are both opponents and fans. The people opposing side argues that its power is very low and beyond f / 8 the effect is negligible is located. Fans meanwhile say it is extremely cheap and delivers what it promises, octopod at least in the price range you are talking. Hypertext
Follow Engadget Photo Newsletter: Subscribe RSS Twitter Facebook Google Plus tablet version Mobile version Thanks to flash, you can have a light source lights albums as you please. However, if we take maximum lights albums possible advantage of the light source, we complicate life a little. There are different kinds of flash, and each well used, it may be appropriate for one type of photography, and can afford to achieve very different results. This chapter initially discuss the characteristics of an integrated flash, and then we will focus on compact flashes, which are the most popular, trying to classify them according to their performance. Finally, we also devote a few lines to ring flash, ideal for macro photography. We call that incorporate integrated flash compact cameras and most SLR cameras. Its main features are: To be included in the camera saves considerable, and the added convenience of always turn to him. The light source is usually small, so in portraits and photographs to nearby objects can create harsh shadows, maybe we do not like from an artistic point of view. Moreover, usually close to the target. For this reason the projected light is very flat, and sometimes gives the impression of reducing the volume of the subject we are photographing. In a portrait, for example, will show a flatter factions. This lighting always has an artificial appearance. In most cameras this flash operates automatically. lights albums This may be a limitation if we want to take pictures with a more or less intense lights albums light than usual, since we can not configure it manually. In most SLRs, however, although the built-in flash is also automatic, can be partially set the intensity of exposure from the camera menus. Its power is quite limited. This means that from a distance, it will be difficult to get properly illuminate the scene. That is why, if we are not careful, we can have trepidadas or underexposed photos. In any case, if you need the flash to illuminate a scene nearby (a group portrait, night, for example) as a souvenir and without major artistic pretensions, this is our flash, no doubt. Despite being a bit simple and configurable tool, the integrated flash can get us some trouble, without major complications. Most cameras do not allow this use another flash. The compact flash is a standalone device that connects to the camera through a pad located on top of it. All SLR cameras lights albums have a hot shoe for connecting this type of flash, like a few high-end compact cameras. Within the compact flashes there are different ranges and features. For simplicity, we can say that the main features of a compact flash BASIC are: The torch is higher and higher, which is having a major source of light. This is important because lights albums although the shadows remain harsh, they are somewhat less than with the integrated flash. Many also incorporate a removable diffuser, which can be used to uniformly illuminate a scene from wide angle. They have more power (guide number), and therefore a greater range. They also tend to have higher refresh rate. Generally, the head can swing in the horizontal and vertical axes. This is probably the most important feature, since it will allow us to "bounce" flash firing into walls and ceilings, thus achieving enlightenment, not only blurred and balanced, but also personalized. In the same way that a frontal flash can flatten a subject, a bounced flash can increase its volume and texture. Thanks to this, get a much more natural light, and the creative possibilities of using flash multiply. We are no longer talking about using the flash when there is no light, but to shape it to our liking. The performance of some models are superior and varied. We can say that the main features of a compact flash ADVANCED are: A high-end compact flash usually be used with manual control. This may seem unnecessary when you just want to take a picture with a front mounted camera flash, lights albums but nevertheless can give us tremendous lights albums flexibility when working in the studio or combine several flashes and accessories. An advanced flash often means more power, better lights albums construction and higher lights albums refresh rate. This allows us to achieve the desired light at longer distances, or more small apertures, and also use the flash burst pictures. Faster synchronization. This is
After several sessions, the results have seen in recent weeks, it is time to comment impressions gentech lighting to the use of such lights, commonly used in USA but unknown in Spain or almost. A starting point, most of the ring lights can be placed decoupled from the camera, so its performance and results become identical to those of a conventional flash with beauty dish or bowl of beauty. Attaching the camera to focus or flash, or shooting from inside the "donut" got a very particular light, as it is very front, almost gentech lighting impossible to reproduce with a normal flash because with the latter we will always be shadows gentech lighting have to " gentech lighting remove him "next to the picture, look like Terry Richardson uses a metal extender attached to place a camera lens strobist flash, but generates a hard shadow with ring would not appear. Like any front light, very flat when not being directed laterally or from above and not have shadows, but you can get much volume in skin and clothes if we get too close, although gentech lighting this have to use focal angle. If the ring light is continuous gentech lighting light, as in my case, it is mandatory to be close or not arrive bright and have to climb much iso camera, apart from having to be in total darkness in the study, as long as we use light continuous, even in this case by the low power of the annular fluorescent (70w to 350w light offer very little compared to tungsten bulbs or 2000w 1000). If we focus or flash to fashion and Length, will not be worth the fluorescent, you will need flash instead of continuous light. The problem with ring flash is price, are much more expensive than normal flashes while having the same performance and power. Obviously there are cheaper versions on the internet but do not make me responsible for the stability and strength of these products. Many will have thought about buying a flash macro ring to use both macro and portrait-beauty, the end is like using a macro lens for portrait other than to macro, which can be used but the results are not as effective as these flashes are not cheap but give little power, are designed to run a few centimeters or even millimeters of objects photographs, and like all flash batteries, it is not stabilized in the flash output or color temperature, gentech lighting apart not available modeling light as a studio flash or continuous light source, essential for portrait, fashion and beauty or completely shut pupils, with negative consequences on the photo thing. Finally add the visual for some Consequently, the pupil reflex, something you love or hate, no middle ground. On the other side is a light that opens much the pupils and clarifies the iris of the models naturally. I leave these pictures of the article as examples of applications in beauty, and if you want to know more about lighting (or retouching, perched, ...)

Hello everyone! Today I'll tell you how I created this ring flash 'home' (to call it somehow :)). All you need is: Glue stick Celo Black Foil Card A sheet of white paper Scissors Ruler Compass Begin taking the target. pincett Devise a circle the diameter of the lens on the black card. Now take the compass and make wider circle 1 cm. And now Make another circle of about 4 cm wide. Now also trim your circle you have drawn having a diameter of 1 cm above the target. Will be a kind of 'donut'. Do the same with the foil and pegadlo on cardboard. From now on, all you who is going to have to be wrapped in foil. Then gather ye flash, and dibujad on cardboard the width. Now dibujad two lines with the flash range of the centimeter spanning from the flash to the rosco we've done before. On the sides, pincett to the tabs, you have to draw another line each at a distance of about 2 inches. Repeat the process pincett for the back but keep in mind that you have to put the flash. He should be a sort of elongated cube with a hole for the flash Acordaros to cover everything foil to bounce light. And would only cover the circle with a black strip to the side and center (seeded with aluminum foil inside) and cover the circle with a sheet of paper. And here's the result (you do not have in mind my face is a picture taken quickly: P) Obviously that is not aesthetic but can prove very cool things with him and low cost price. And if you urge you can take a paint :) I think I'll paint mine with yellow POSCA: D Related This entry was tagged cheap, carreño carmen, home, camera, flash, pincett ring flash, photography, make, lighting, low cost, light, photography, price, tutorial.

We already know that incandescent bulbs are disappearing toio because they are incredibly wasteful, radiate heat better than light. Most of our readers toio also know that compact fluorescent lamps (CFLs), surpassing "bulbs Ilyich" in almost every way, gradually giving way to LED counterparts. The latter should be the next "gold standard" for manufacturers of lighting products. But are LED bulbs compact fluorescent better? If so, how? To give a definite answer to this question, not a key indicator to evaluate energy efficiency light sources (lumens per watt). We need to do a complete analysis toio of the life cycle of both products - the only way to find out which one will come first. Must take into account all energy-intensive: the production, use, transportation. You must also consider how many lamps can operate longer period specified by the manufacturer, and how much - will fail until then. The graph above in a very visual form, the results of the study, and below is an excerpt toio from the report toio of US Department toio of Energy: Average power consumption of LED lamps and CFLs are comparable in terms of the life cycle of devices and is about 3900 MJ 20 million. Lumens - hours. It is about four times lower compared toio to an incandescent lamp. By 2015, when developers LED lamps will meet its targets for performance of the devices, their energy consumption in the context of the life cycle is expected to decrease toio by about half. In addition, based on our analysis, the following conclusions: phase "use" if incandescent, compact fluorescent and LED lamps are the most energy-intensive, toio it accounts for about 90 percent of the total energy light sources in the context of their life cycle. Followed phases of production and distribution, respectively. The share of transport accounts for less than one percent of the total energy consumption in the context of the life cycle in the case of bulbs of all types. It turns out that CFL and LED current generation about the same in terms of energy consumption. But there are several factors that cause consumers to prefer technology LED. For example, LEDs are less fragile than CFLs, and they do not emit mercury toio in violation of the integrity of the shell. In addition, LED- lamps are about 3 times faster and longer included. But the real leap forward will take place for about 2 years when the market will be the next generation of LED lamps. We already wrote about one of the leading lamps from Philips, which gives 200 lm / W. Light sources with this line should be about twice better current LEDs and CFLs.

When laid off the road - it's nice especially nice rush on the highway at night, knowing that to reach your interception dare only one. What you need? But very few - should disperse the darkness ahead bluish-white beam of xenon. Xenon headlights lumens per watt appeared in our country in 1992, it is "definitely" providing their owners prefer moving. SECURITY & visibility "Xenon", but in fact, discharge (or HID) lamp emits high intensity light output by the glow of gas, initiated by arc discharge between two electrodes. Lamp electrodes are in a flask filled with xenon under high pressure (30 atm. In working order and about 120 atm. In the mode of combustion) and metal salts. The light emitted by a xenon lamp, intensive conventional twice (at lower power consumption), and thus significantly improves and visibility. If normal lumens per watt automotive 45-watt bulb emits light output of 600 lumens and 55-watt halogen - 1550 lumens, the xenon lamp power of 35 W publishes more than 3000 more than noticeable difference! The geometry of the illuminated area roads also improved because the light tunnel lights equipped with a xenon lamp, much more. The emission spectrum of xenon as close to the spectrum of sunlight that allows you to see objects (both on the road and on the side) invisible to ordinary mortals. ADVANTAGES xenon xenon lamp service life of about four years (average service life of xenon lamp type D2S (R) -2800-3000 h) and guaranteed service life of conventional galogenok just 180-500 hours (depending on the type of lamp and manufacturer) . Since no xenon lamp filament (the main feature, which "by eye" can be distinguished lumens per watt from pseudo real xenon), and thus there is nothing perehoryaty and end up, she is not afraid to shock and shaking. Another plus - lower temperature light because a headlight does not overheat. Now you can easily vlitaty in the mud with glowing lights - cracks on glasses will not appear. Of course, xenon lamp heats, but with power consumption of 35 watts only about 7% of the energy is "in heat". And halogen - about 40% (with a minimum consumption lumens per watt of 55 W). DISADVANTAGES disadvantages of xenon also missing. First - the need for a special, complex control unit. In order to ignite xenon lamp, it must submit lumens per watt a voltage of about 25 000 V, and in the process necessary lumens per watt in 80 (with a frequency of 300 Hz). Permanent power system does not provide such conditions. For this purpose, Starting regulating devices, lumens per watt also known as "incitement blocks", "ballast" or "xenon units." (It remains to enjoy the fact that through the use of such a device is the power of the light flux ceases to depend on changes in supply voltage). Not only do most lamps - fun not cheap, so also is desirable to change them in pairs, because eventually (after about 200 hours of work) emission spectrum of xenon change. Therefore, all the firms sales give customers a paper that says something like: "All complaints on luminescence spectrum taken after 200 (two hundred) hours operating time" and immediately warned that in case of replacing only one lamp - headlights will shine a different light. Another shortcoming - the need to constantly lumens per watt monitor the regulation headlights not to blind oncoming drivers. Some countries have banned the use of xenon without automatic corrector, tracking the status lights. Blue Glow NIGHT To start us see what happens xenon light. lumens per watt In reality, it is not always blue and blue - not necessarily the most striking, as the human eye sees best yellow lumens per watt and red light. The sun has a color temperature of about 5000-6000K, a color temperature associated with the brightness of the light. The closer the color temperature to 5000K, the closer the spectrum of the radiation source to sunlight. Light Xenon HID lamps have a bluish tint, and conventional halogen - yellow. A lamp with a temperature of 12000K shines in only 5% brighter than conventional 55-watt galogenki. Those who set himself on machines 7000K lamps and more often complain that night in the rain the road is not visible at all. In dry weather on an unlit road everything is as black and white screen - many details are lost and stolen bumps on the road. In general, the brightest bulb temperature of about 5000K with. If the figure is higher - the illumination of the road deteriorates. In line usually go with temperature 4300K lamp. They are available as accessories. And if the light is 4000K explicit yellow tone, after the 4000K range shifts to a greenish tint. And after the 6000K range "is" in the blue. Of course, all this refers specifically to the lamps. In the headlight may be some variations in color glow
Let there be light: detail of halogen, xenon and LED | Car Portal How sharp and chip in the age of the car and electrification least strange than bills in modern accounting. cfl bulbs dangers However, the first car during live fire is lighted path at night. We used kerosene and even candle burner. Carbide (or acetylene) lights have been better, but only with the advent of incandescent bulbs automotive world has really convenient cfl bulbs dangers and practical. As in life, in a modern car can meet almost cfl bulbs dangers all known types of electric lamps. And now it is in the automotive world are extremely serious changes. New developments, pushed as engineering and fashion trends, change the existing view of the world in the car. The most famous and popular - so-called bulb. In their light source is a kind of fiber (mainly tungsten filament), which is under the influence of an electric current through it heats up and begins to emit light. The shape of the bulb may be different for the desired brightness and scattering. A few words of tungsten. If iron melts at 1535 operating system, the tungsten cfl bulbs dangers - with 3410 OS. Given that the filament temperature of about 2500 OS and higher credit tungsten simply invaluable. But the limit of these lamps is clearly apparent and understandable. The biggest drawback of incandescent lamps - their inefficiency. These lamps are very expensive. They produce less light than they consume energy. More than 90 percent of the energy goes to heat and 10% less directly in the world. Their efficiency increases with the power expended. For example, a 100 watt light bulb to shine much brighter than the two 50 watts. Over time, as the tungsten evaporates slowly, its walls covered with condensed vapor bulb inside the lamp and the light fades with time. Halogen cfl bulbs dangers lamps are also incandescent bulbs, but they use another filler - halide (iodine or bromine), which connects ysparyvshyysya tungsten, rather than letting it settle on the walls of the flask. But the most interesting thing is that the more connections in contact with the hot coil split. Thus tungsten filament cfl bulbs dangers rotates, and halides - the atmosphere bulb. That is a kind of restoration thread lamp called halogen cycle. This process requires cfl bulbs dangers a temperature of about 200 oC. That is why these lamps so hot and not like moisture and fingerprints on the glass. Usually they have a double cfl bulbs dangers hull, which somewhat reduces the external temperature of the lamp and also increases the efficiency of halogen cycle. Simple lamps have a color temperature (global characteristics of the emitted spectrum measured in Kelvin) about 2700K, and halogen - 3000K. Halogen bulbs though more difficult and expensive (if so 5-10), but also more effective. To begin with, they are 25-30% brighter than conventional incandescent bulbs. Even at the end of its "life" halogen lamp gives up to 95% of its original brightness (simple lamp - about 75%). Simple lamp "live" approximately 1000 hours, while halogen approximately 2 times longer. However, Guinness World Records says the filament that burned for more than 70 years. But not immediately say that this time it never turns off, and that's important. The process of inclusion (as in many electrical devices) - the wear and heavy lamp procedure. Better if it occurs gradually. Halogen lamps are living as much as they meted out without miracles. It is important for the life of incandescent sustainability stress. Excess cfl bulbs dangers voltage of 4% may reduce its service life by 40%. This relationship works and back. 4% lower voltage also able to significantly increase the life of the lamp. However, its brightness and thus will be lower. In incandescent there is another disadvantage where significant in light of their automotive applications. It is a thin spiral consisting of tungsten relatively fragile. Shaking and vibration in the car are not conducive to comfortable work lamp. Although specific design solutions have allowed largely eliminate cfl bulbs dangers the risk of such damage. Despite the emergence of new, higher quality and reliable light sources, tungsten, being cheaper, retain positions that simple. There are new and their types. Main work of engineers focused on reducing the rate of evaporation of tungsten filament. The cheap lamps flask filled with a mixture of nitrogen and argon. In more expensive instead of using krypton argon, cfl bulbs dangers which has a lower thermal conductivity. Can also be used xenon, in which the figure is even lower. The use of these gases can increase the brightness cfl bulbs dangers of the lamp by 10% (krypton) or almost 2 times (xenon). Xenon deserves special cfl bulbs dangers mention. Too much around there are rumors, gossip and cheating. To begin with, there are xenon and xenon-filled lamp. Latest - a classic representative lamps

E. Illumination Light stream and can come from non-self-luminous bodies that reflect or scatter light that falls on them. Therefore, a number of practical and scientific tasks necessary to know how much luminous pulsar lighting flux incident pulsar lighting on a particular part of the body. For this we introduce a physical quantity illumination. Illumination is numerically equal to the full luminous flux incident on the surface element to the area of Where a - angle between the normal to the plane of dS, which define the illumination, i direction of light, d S n - a plane perpendicular to the flow, I - intensity point source. The unit of light energy in SI is watts per square meter (W / m'2). Brightness V. For many lighting tasks can be considered some sources pulsar lighting point. However, the size of most sources can not be neglected. To characterize these self-luminous and nesamosvitnyh (lit by reflected light) sources put photometric brightness value in a certain direction. It characterizes the radiation luminous surface in that direction. The brightness is determined flux, which is sent in a certain direction unit apparent surface in the unit solid angle. SvitnistR. If the light source is finite (or a glowing, luminous reflected light), the luminance source called surface density flux radiated by the surface pulsar lighting in one direction in all directions within the angle cr. If the surface pulsar lighting element dS emits (reflects) dF flow in one direction, then. For uniform luminance can be recorded. Unit of luminance in SI - lumens per square pulsar lighting meter (lm / ma). The unit of luminance energy in SI is watts per square meter (W / m2).
