Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, and in particular to an automotive lighting lamp and its thick-walled component. Background Technology

[0002] The thick-walled component is a light guide structure on a vehicle headlight, used to propagate the light beam. In existing technology, thick-walled components are generally integral light guide structures, with a concentrator on the light-incident surface and an emitting pattern on the light-emitting surface. The light source is located at the focal point of the concentrator, and the emitted light propagates through the thick-walled component, finally diffusing through the pattern on the emitting surface.

[0003] In order to achieve a better appearance, the exposed parts of thick-walled components (i.e., the parts not covered by the lamp holder trim) have many smooth areas without optical patterns. This results in stray light generated by the internal optical structure being visible in these smooth areas, affecting not only the vehicle's own lighting performance but also interfering with other road users. In existing technologies, to eliminate stray light generated by the spacing surfaces of different collimating units in thick-walled components, a textured surface is typically used to cover the smooth areas without optical patterns in the lamp holder trim. While this prevents the stray light generated inside the thick-walled component from being visible in these smooth areas, it does not meet the customer's requirement for a crystal-clear appearance. Alternatively, a rough texture can be added to the spacing surfaces that generate stray light to weaken the reflected light, but this method is not ideal in removing stray light and requires high-quality molds for forming thick-walled components, resulting in higher costs.
