Problems solved by technology

The existing HID automotive metal halide lamps have a significant disadvantage. When they are turned on, the visual stimulation to the driver of the oncoming vehicle is very large, which may easily cause the other party's sight to be unclear and bring hidden dangers to driving safety, especially the 8000K and 10000K HID automotive metal halide lamps with high color temperature. This is especially true for lamps, which has also led to Western countries not allowing the sale of automotive metal halide lamps with a color temperature higher than 5000K

Embodiment 1

[0013] Embodiment 1: The anti-glare treatment technology of HID automobile lights adopts the following treatment method: the outer surface of the outer quartz tube of the lamp cap is subjected to physical frosting surface treatment to make it a translucent quartz tube. During physical frosting treatment, silica sand is used to spray the outer surface of the quartz tube under the action of compressed air to form an uneven frosted layer on the surface of the quartz tube.

Embodiment 2

[0014] Embodiment 2: The anti-glare treatment technology of HID automobile lights adopts the following treatment method: chemically frosting the inner surface of the outer quartz tube of the lamp cap to make it a translucent quartz tube. For chemical scrubbing, first mix 10KG of 55% hydrofluoric acid, 25KG of 40% hydrofluoric acid, 9KG of fluorspar powder, 7KG of sodium bicarbonate, 25KG of ammonium fluoride and 4KG of calcium hydrogen phosphate. Pour it into an iron pot and heat it (80-90°C in winter, 40-50°C in summer) to prepare a frosting solution. Then, the sanding solution was poured into a plastic sander, and the quartz tube was sprayed continuously. After about 1 minute, rinse off with water. Then use aqueous hydrofluoric acid (concentration 40% HF:H 2 O=10:1) corrodes the acute angle on the surface caused by grinding and turns it into an obtuse angle, increasing the strength of the quartz tube. Finally, rinse it with tap water, and the inner surface of the quartz t...

Abstract

The invention discloses a dizzy-proof disposal technique of an HID automobile lamp, which adopts the techniques as follows: surface disposals of the internal surface or external surface of the quartz pipe of a lamp head is carried out, so as to lead the quartz pipe to be half-transparent. The method of surface disposal can be a frosted finish process or a grinding process. Therefore, light beams pass through the half-transparent quartz pipe and are refracted outwards through multi-point along the multi-direction, the perpendicular incidence of light beam and the dizzy light of an HID automobile metal halide lamp are obviously reduced, and the drivers of opposite vehicles feel comfortable, thus having safer driving. Furthermore, after the surface disposal, the color rendering index of the HID automobile lamp is improved to a certain degree.

Description

technical field [0001] The invention relates to an anti-glare treatment technology for automobile lamps, in particular to an anti-glare treatment technology for HID automobile lights. Background technique [0002] The HID automotive metal halide lamp has high brightness, and its structure generally includes a lamp holder and a lamp holder, and the outer layer of the lamp holder is sealed by a quartz tube. The existing HID automotive metal halide lamps have a significant disadvantage. When they are turned on, the visual stimulation to the driver of the oncoming vehicle is very large, which may easily cause the other party's sight to be unclear and bring hidden dangers to driving safety, especially the 8000K and 10000K HID automotive metal halide lamps with high color temperature. This is especially true for lamps, which has also led to Western countries not allowing the sale of automotive metal halide lamps with a color temperature higher than 5000K.
