Problems solved by technology

[0003] With the development of technology, today's cars can change the distance and angle illuminated by the lights by adjusting the focus. The light emitted by the LED passes through the PC lens and then irradiates the road surface to achieve the lighting effect. The point is different, the light irradiated on the road surface may appear light spots, especially on the road with less light, the light spots will affect the lighting effect, making it difficult for the driver to confirm the road conditions ahead, which increases the danger of driving at night

Abstract

The invention discloses a lens treatment process for a zoom LED lamp. The method specifically comprises the following steps that S1, quartz sand is used for carrying out sand blasting treatment on theouter side curved surface or plane of the lens, and after treatment is completed, dull polish treatment is carried out on the protruding parts of the corners of the lens, so that the surface roughness of the outer side curved surface or plane reaches 30-45 microns, and the surface roughness of the protruding parts of the corners of the lens reaches 100-150 microns; and S2, the lens is put into apolishing solution for polishing treatment, and scratches caused by medium sand blasting or dull polish on the surface of the lens are polished away. According to the invention, the outer side curvedsurface or plane of the lens is subjected to sand blasting treatment, so that light spots irradiated by the LED lamp are uniform and have no obvious boundary, and the convex parts at the corners of the lens are frosted to reduce the refraction of the convex parts at the corners to light, thereby removing more than 98% of obvious light spots on the lens, avoiding the imaging problem of the light spots at the corners after the LED lamp is zoomed, and reducing the generation of the light spots.

Description

technical field [0001] The invention relates to the technical field of optical lens processing, in particular to a lens processing technology for zoom LED lamps. Background technique [0002] The earliest light sources used in automobiles were halogen bulbs and xenon bulbs. Due to the high heat generation, the lens used was chosen to be glass. Although it is heat-resistant, it is also heavy and has a relatively simple shape. With the development of technology, LED cold light sources The use makes the PC lens also suitable for the car lamp, which improves the problem of the heavy weight of the vehicle lens. [0003] With the development of technology, today's cars can change the distance and angle illuminated by the lights by adjusting the focus. The light emitted by the LED passes through the PC lens and then irradiates the road surface to achieve the lighting effect. The difference is that the light shining on the road surface may have light spots, especially on the road w...
