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
