Car lamp manufacturing method and car lamp manufactured by same

Abstract

The invention discloses a car lamp manufacturing method, which includes the following steps of 1) producing a multi-angle light source module; 2) producing a constant-current driving circuit board; and 3) producing a lamp holder. The invention further discloses a car lamp manufactured by the car lamp manufacturing method. The car lamp manufacturing method is simple in process, low in cost, easy to realize and capable of quickly manufacturing car lamps with large lighting angle and fine lighting effect. In the car lamp, disc-shaped light sources and elongated light sources of the multi-angle light source module are distributed scientifically to form a novel light distribution scheme, light distribution is convenient and flexible, lighting angle is large, light distribution by conventional lighting panels or lenses can be avoided, and error appearing in secondary lens optical simulation and affection on light effect from actual construction mounting can be reduced well. In addition, the projections with light reflecting function and heat radiation boosting function are arranged, thereby light distribution effect can be improved well, heat radiation effect can be improved, and the service life of the car lamp can be prolonged effectively.

Description

technical field [0001] The invention relates to lamp manufacturing technology, in particular to a method for manufacturing a car lamp and a lamp manufactured by implementing the method. Background technique [0002] When a driver is driving a vehicle in dark conditions, headlights are crucial for the driver to see objects on the road and on the side of the road. At present, incandescent lamps, halogen lamps or discharge lamps are generally used as illuminants for automobile headlights, and these illuminants all have some problems. Halogen lamps, such as H4 bulbs, have a large luminous volume, short life, low light energy utilization rate, and the illuminant is not strictly distributed in Lambertian bodies, which brings certain errors to the design, and the design accuracy of the headlight is difficult to guarantee. Although discharge lamps have high luminous efficiency, light intensity and lifespan, they are not conducive to energy saving due to their high power. Especially...

AI Technical Summary

Problems solved by technology

[0003] Although the existing LED car lights can meet the lighting function of the car during driving, its structure is complicated, the manufacturing cost is high, and the brightness and uniformity of the light are not ideal, and there are shadows, which affect the safety of driving. In addition, its production process Many, low production efficiency, and inconvenient to install and maintain
