Processing method of headlight optical sample

Abstract

The invention relates to a processing method for an automotive lamp optical sample piece. The processing method for the automotive lamp optical sample piece comprises the following steps: processing the front surface of the automotive lamp optical sample piece until processing of the front surface is finished completely, wherein a side profile of the sample piece is milled out between a theoretical margin of the sample piece and a blank periphery solid portion besides several small portion regions are retained at intervals, meanwhile, a shallow groove type surface which is fluctuant along withthe height trend of the margin of the sample piece is formed, and the depth of the portion, which is closely neighbor to the margin of the sample piece, of the shallow groove type surface is smallerthan the thickness of the corresponding local sample piece margin; processing the reverse surface of the automotive lamp optical sample piece until processing of the reverse surface is finished completely, processing the surface between the theoretical margin of the sample piece and the blank periphery solid portion, and enabling the surface to be fluctuant along with the height trend of the margin of the sample piece, wherein a large portion of the surface and the shallow groove type surface form a thin material layer, and the surface and the surfaces of the small portion regions form a thickconnecting and supporting structure; removing the material layer from the front surface; and cutting according to a designed profile passing line to disconnect the connecting and supporting structurefrom the sample piece. By the processing method, the quality of the optical sample piece can be improved remarkably, particularly, the surface quality of a reflecting surface can be improved, and therefore, a light distribution experiment can play a role well.

Description

technical field [0001] The invention relates to a processing method for an optical sample of a car light, in particular to a processing method for an aluminum sample. Background technique [0002] Car lights are not only the exterior parts of a car, but also the functional parts. With the rapid development of the automobile industry, the requirements for car lights are getting higher and higher. The development of car lights is reflected in various aspects such as appearance aesthetics, light intensity, and light control. From a square glass cover with a halogen bulb that can only illuminate 30 to 40 meters in the past, to a streamlined shell equipped with xenon headlights, LED headlights and even laser headlights that can cover hundreds of meters, these qualities The leap forward is inseparable from continuous experiments, especially light distribution experiments. The deviation between theory and reality leads to the need to make a large number of optical samples for rep...
