The preheating time in a lamp can play a very important rolo.Kapoies lamps arrive at 100% brightnes

The light bulbs are an integral part of our culture for nearly 140 chronia.Xekinisan with ordinary incandescent bulbs in 1879 but now there are dozens of types and several different types of lamp. A few words about the history martin lighting of lamps
Although the discovery of the light bulb became official in 1879 by Thomas Edison, there were dozens of inventors proigithikan.I first discovery of the electric light was made in 1802 and then followed by several others, but none managed to not become commercial.
So the first integrated martin lighting electric lamp made in 1879 by Thomas martin lighting Edison martin lighting bought existing patents and developed so that they can become commercial. Features Bulb brightness (lumens)
All lamps have a common unit of comparison is the foteinotitas.Afti Lumen.Oso Most lumen brighter the lampa.Oi household lamps are usually martin lighting 400-1200 lumen.Yparchoun course up until 15000 lumen lamps. Consumption (Watts)
To the most important martin lighting element of a lamp post brightness is katanalosi.I kilovatores.Mia consumption measured in kilowatt hour is 1000 Watts for one ora.Opote, as many watt is a bulb the more energy katanalonei.Vevaia not have to look only watts or only the lumen but their correlation, ie how many lumen / watt is the lampa.Etsi can distinguish the efficient apodotikoteri.I currently commercially are metal halides martin lighting (up to 115 lumens per watt) and high pressure sodium reach up to 140 lumens per watt, although experimentally the LED have to go far (they break the limit of 300 lumens per watt) LED .Emporika are currently moving to 70-90 lumens martin lighting per vat.Oi fluorescent move 40 -110 lumens per watt (tube lamps achieve martin lighting better performance up to 110 lumens per vat.Oi compact reach 60-70) while the halogen 12-22 lumens per vat.Pio detail you'll see in the chart below (which, however, is a little old relative to the LED and metal halide) lamp Circles (Switch cycles)
Each lamp has a certain number of cycles martin lighting of opening / closing can withstand before kaei.O it varies considerably from lamp to lamp and if there are variations in the number and the same type of lamp as the quality most often associated with eidos.Afti the moment most circles have lamps LED.
Besides the number of cycles the lamps have a certain number of hours that can antexoun.Fysika martin lighting the larger the number the kalytera.Pali varies widely from species to species and sometimes also between the same type of LED lampas.Kai here leaders.
Something that has sufficient importance when we want to choose the lamp, the temperature of the color ekpempei.I color temperature measured in Kalvin.Oso lower the temperature, the hotter (yellowish) will be the greater the more fos.Oso cold (blue) martin lighting .When is around the middle is white oudetero.Oi commercial lamps starting from 2400 Calvin martin lighting (who is warm yellowish color) and go up to 6000 (some fluoride), which is a cool color.
The preheating time in a lamp can play a very important rolo.Kapoies lamps arrive at 100% brightness in less than half a second and some may even make lepta.Afto 5 may be important for selecting a lamp in a point we want to highlight martin lighting directly with that will open the diakoptis.O warm-up time has to do primarily with the technology lampas.Oi halogen and LED bulbs are virtually zero warm-up time while fluorescent lamps can be quite important.
There are several slots in the market for more classical lampes.I socket is screwed E27 (ES) and E14 (SES), which is the discovery of Thomas Entison.Alla enough alla.Palaiotera was quite widespread and Bayonaite (B15 and B22) which are this with the 2 terminals on the side, but has abandoned pleon.Mporeite can see in the diagram below all slots
O Colour Rendering Index indicates how rich and intense the fos.Einai on a scale of 0-100 with 100 being the maximum and mean that it is as natural light iliou.Kalo is the color rendering index is at least more 80.
A very good guide here (English) Types of electric lamp There are several types of electric lampas.Oi Most trade is not of course, but for specific uses (eg, microscopes, telescopes, workshops ...) Commercial light bulbs are mainly as follows: Lamps Incandescent Lamps gas discharge lamps, LED lamps, arc lamps, incandescent
The incandescent lamps operate with the existence of a very thin metallic filament which is located in an airtight chamber with low pressure gas, which with the passage of electric current,
