Car of high-pressure xenon lamp luminous principle is that through the supercharger will the car 12 v dc voltage instantaneous pressure to 23000 volt electric current, arc by ultra high pressure to produce no tungsten poles, after high pressure amplitude excitation crystal glass tube of xenon free electrons, in between two electrodes as strongly as day light, HID xenon lamp to replace the traditional halogen lamp will be a big trend in the development of automobile.

Automotive xenon lamp

The halogen headlamps of the general vehicle original factory mostly need to consume 55-105W or so of electricity, while the HID gas discharge large lamp group under the stabilizing action of the stabilizer, the running current is only half of the halogen lamp, and only 35W of electricity is needed on average to supply the xenon light bulb. As for the savings in electricity, they are equivalent to the savings in gas.

Normal HID light flux is 2400 lumens or so, it is 3 times above of common halogen lamp. HID lamp color temperature from 3000K to more than 12000K; The higher the color temperature of a lamp, the less it penetrates fog and rain. The light color at about 6000K is exactly the color temperature with the whitest beginning to turn blue, and the color closest to the midday sunlight. The human eye has the highest receptivity. Such lights can effectively reduce drivers' visual fatigue when used in the night lighting of vehicles, and the increase in the brightness of vehicle lights can also effectively expand the visual range in front of the vehicle, thus creating safer driving conditions.

As a result of HID lamp does not have filament, won't produce because of filament fuse and scrap because of this problem, service life is longer than halogen lamp, reach 2800 above, longer than halogen lamp 10 times.

From the arc characteristics of xenon gas at high pressure, it can be seen that it is a convective stable arc. If the xenon lamp is crossed, the arc will bend upward, the arc shape will change, and the photoelectric parameters will also change. Especially when the convection is too strong, the arc will be seriously up, or even blown out. Therefore, the magnetic field must be used to stabilize the arc. For the small power xenon lamp with small pole distance, it can be excluded because its arc is of transient stable type. It can be seen from the brightness characteristics of xenon lamp that the distribution between negative and anode is very uneven, but there is a cathode spot near the cathode and the brightness is extremely high. Therefore, it should be used as much as possible when designing reflective bowl, so as to obtain a high light utilization rate.
