HID Light description
First, what is the Xenon lamp
Xenon lamp and with a new xenon headlamps, also known as high-intensity gas discharge lamps, the abbreviation HID Intensity Discharge Lamp.. Xenon lamp broke Edison's tungsten light principle, the quartz tube filled with inert gas-Xenon high-pressure xenon gas, to replace the traditional filament, the two electrodes with mercury and carbon compounds, through the ballast to 23,000 volts high voltage current xenon light stimulation in the formation of perfect white between two poles arc
2, xenon lamp (HID) light-emitting principle:
Auto HID xenon lamp and halogen different from the traditional, which is a high-pressure discharge lamp, its light is the use of positive and negative electrical stimulation of xenon chemical reaction with the rare light, therefore there is a small glass tube inside the ball, this one is the irrigation filled with xenon gas and a little rare, so long as they use the current to stimulate the chemical reaction, the two will send up to 4000K-12000K color temperature of light. It uses a special ballast, 12V car battery voltage is generated using more than 23000V trigger voltage of lamp start. Start the brightness of 0.8 seconds when the brightness is rated 20% to the brightness of halogen lamps, headlamps and to less than 4 seconds to more than 80% of the rated brightness.
Third, Xenon lights (HID) performance advantages
1, the average 55W halogen lamps can only produce 1,000 lumens of light, while the 35W Xenon lamp produces 3200 lumens of light, brightness increasing by 300%, with ultra-wide-angle long and broad vision, to bring you an unprecedented driving Car comfort; for the night is no longer dark and vision more clearly, can greatly reduce the traffic accident rate.
2, HID xenon lamp is the use of electronic excitation of gas emission, there is no tungsten, therefore longer life expectancy is about 3,000 hours, substantially exceeded vehicle traveling at night the total number of hours. And halogen only 300 hours.
3, strong saving: a Xenon lamp only 35W, and 55W halogen lamp issue is 3.5 times more light, greatly reducing vehicle power system load, power loss save 40% corresponding increase in vehicle performance, energy conservation.
4, good color temperature: 4300K-12000K, etc. There, 6000K close to the sunlight, by the majority of users, and halogen only 3000K, light color dark red.
9, above some of the more specialized knowledge is introduced, the following are some of the domestic market situation
the situation is grim for domestic competition, so there are some small factories in order to save costs, enhance their own products, the price advantage the use of some of the more inexpensive components, which make up the product discharge voltage has been less than 23000V, some factory discharge pressure may be only 19000V 17000V of all or only, this way there will be a lot of light bulbs can not match of.
10, HID common problems
1. Electromagnetism is too large, will affect the DVD, radio and some other electronic products, normal use, the easier to solve, just add a filter on it, 2, current is too large, such as Benz, BMW, Audi and some high-end cars with computer-controlled system will automatically alarm, the car had not even normal use, it must add a set of decoding CAN BUS system, there is a ballast itself there are also additional decoding harness, or use a lower starting current BALLAST, such as starting current lower than the 5A's can be solved, 3, is a dedicated car HID, there are many imported car is not take, like Toyota's part of the car only with the kind of dedicated ballast imports, and !
