Problems solved by technology

[0002] Automobile headlights are the main accessories in the field of auto parts and are widely used in the automobile industry. Automobile lights not only provide lighting for drivers but also have the function of prompting and early warning during driving. The quality of automobile lights is related to car drivers. However, due to poor material quality and internal air leakage, many car lights have malfunctioned, which affects the normal driving of drivers. The application number is CN200910031279.9, which discloses a transmission type high-power LED car. Low beam lamp and its production process. This process uses optical equipment to distribute the light emitted by the LED light source through secondary light distribution, which solves the two major problems of heat dissipation and light distribution. The luminous efficiency is high, the light source is uniform and soft, and the service life is increased by 4- 5 times, which is more conducive to the lighting in front of the road and high-speed driving, but the optical equipment used in this process increases the cost of the process, making the cost higher, and the life of the LED lamp is shorter, and it is easier to damage quickly under high-power working conditions. Not conducive to marketing

Embodiment 1

[0020] A kind of automobile headlight production technology of the present embodiment is characterized in that, its processing steps are as follows:

[0021] (1) Material selection: 3cm tungsten wire is selected as the car lamp filament to ensure the lighting intensity and quality of the car lamp;

[0022] (2) Mounting: Weld the filament selected in step (1) to a 5cm-high lamp holder, which is composed of a molybdenum rod and a quartz glass rod, so that the power on the lamp is suitable and reasonable;

[0023] (3) Spot welding the molybdenum sheet: spot-weld one end of the molybdenum sheet to the molybdenum joint of the light frame in step (2), and spot-weld the other end to the molybdenum foot of the base;

[0024] (4) Press seal the hole: the wick made in step (3) is sealed in the glass shell in a clean room with a constant temperature of 30°C. The molybdenum foot protrudes from the lower end of the glass shell and leaves a vent hole. Height 9cm;

[0025] (5) Bright hydro...

Embodiment 2

[0029] Example 2 : The rest is the same as the above-mentioned Example 1, the difference is that in step (1), a tungsten wire with a length of 4 cm is selected, and in step (5) hydrogen gas is filled at 0°C, and in step (6), at -9°C Under the condition that the high pressure is 170kpa, in the step (2), the lamp holder is composed of a molybdenum rod and a quartz glass rod.

[0030] Example 1 Example 2 Example 3 Filament illumination intensity 100w 95w 90w Service life of car headlights 36 months 40 months 39 months

[0031]

[0032] Through the above three examples, there are three sets of data in the above table. It can be seen that when a tungsten filament with a length of 3 cm is selected, the filament illumination intensity is the largest. It is beneficial to the production of automobile headlights.

[0033] The invention completes the production of automobile headlights through eight steps of material selection, mounting, s...

Abstract

The invention discloses an automobile headlight production process which comprises the following steps: (1) selecting a material; (2) mounting a frame; (3) implementing point welding on a molybdenum plate; (4) implementing pressure sealing and forming holes; (5) highlighting hydrogen; (6) exhausting air; (7) welding; (8) inspecting a finished product. The automobile headlight production process is reasonable and simple in step, reasonable in material selection, low in cost, high in quality and applicable to popularization in the automobile lamp industry, the process procedures are greatly simplified, most importantly, the service life of the automobile lamp is prolonged due to addition of a rare gas xenon, and due to addition of a reinforcing ring, faults such as welding off of the automobile lamp because of vibration are avoided.
