HID principle and performance characteristics of light-emitting

First, xenon lamp concept

Xenon lamp is a new type containing xenon headlamps, also known as high-intensity gas discharge lamps, the English referred to as HID (IntensityDischargeLamp). Its principle is anti-ultraviolet UV-cut crystal quartz glass tube, filled with a variety of chemical gases, mostly for the xenon (Xenon) with iodide and other inert gases, and then through the supercharger (Ballast) the car 12 volt DC voltage on an instant boost to 23,000 volts of current through the e-free, in the light between two electrodes, which is called the gas discharge. Generated by the xenon car light super white, light color temperature can increase the value of a similar day of sun light, HID amount of current required to work only 3.5A, brightness is three times that of traditional halogen bulbs, the service life than traditional Halogen bulb 10 times longer.

Second, the xenon lamp 's light principle

Car xenon lamp with traditional halogen different, this is a high-pressure discharge lamp, and its light is the use of positive and negative electrical stimulation xenon light-emitting chemical reactions with metals, so the ballast, the voltage generated by the car battery 12V trigger voltage over 23000V the lamp starts. Brightness of 0.8 seconds startup is rated brightness of 20% to the brightness of halogen lamps, headlamps and to less than 4 seconds to reach 80% of the rated brightness. Ballast in the lamp stabilized power supply to the lamp voltage of about 80V to maintain constant lamp power operation.

Third, HID 's performance characteristics

1, high brightness: the general can only produce 1000 lumens 55W halogen light, while the 35W xenon lamp produces 3200 lumens of light, brightness increasing by 300%, with long and ultra-wide field of vision, to bring you unprecedented driving comfort; for the night is no longer dark, vision clarity, can greatly reduce the traffic accident rate.

2, long life: HID light is the use of electronic excitation of gas, tungsten does not exist, so live longer, which is about 3,000 hours, substantially exceeded vehicle traveling at night the total number of hours, and halogen only 250 hours.

3, energy: xenon lamp is only 35W, and 55W halogen lamp issue is 3.5 times that of light, greatly reducing vehicle power system load, the power loss save 40% corresponding increase in vehicle performance and save energy.

4, good color temperature: 4300K-12000K, etc. There, 6000K close to the sun, the majority of users, and halogen only 3000K, light color dark red.

5, safe and reliable: Safety is the HID 's biggest attraction, many used the HID reaction owners to install the HID lights good vision, night driving safety is greatly enhanced. Mainly because the HID lamp to bring the multiple beams and intensity than the simple and low beam settings more effective, can greatly improve the car in front of the lighting, illuminated street signs, the importance of road safety is no doubt .

6, the emergency, the xenon lamp and halogen light-emitting principle is different, when the battery power supply problems, will extend a few seconds before it goes out, so that the owners have some time to deal with emergencies.
