Method and device for improving luminance of dark space on lateral edge of inner matched lens

Abstract

The invention discloses a method and device for improving the luminance of a dark space on the lateral edge of an inner matched lens. A matched lens support (2) is arranged above a light source, and a matched lens decoration ring (3) is arranged at the front side of the light source. A high reflecting material face (6) is arranged on the portion, facing the light source, of the support. A high-reflectivity material can reflect part of light hit to the high-reflectivity material onto the inner matched lens edge where perpendicular incidence cannot arrive, so that the luminance of the dark place on the edge is improved. According to the method and device for improving the luminance of the dark space on the lateral edge of the inner matched lens, the method and device for improving the luminance of the dark space on the lateral edge of the inner matched lens can be used for replacing parts, where aluminizing is required but cannot be achieved for various reasons, in an automotive lamp.

Description

technical field [0001] The present invention relates to a vehicle light fixture, in particular, the present invention relates to a method and a device for increasing the brightness of a dark area at the side edge of an inner light distribution mirror. The method and device for improving the brightness of the dark area on the side edge of the inner light distribution mirror can be used to replace the components in the lamps and lanterns that require aluminum plating but cannot be realized due to various reasons. Background technique [0002] With the rapid development of automotive technology, the miniaturization of on-board electronic products or mechanical components is required. For car lights, the miniaturization of on-board electronic products or mechanical components makes the space for each function smaller and smaller. However, on the other hand, consumers have higher and higher requirements for automotive lighting. For example, lighting uniformity has become a basic ...

Problems solved by technology

[0005] In the first case, the LED circuit board is placed parallel to the measurement screen. In this case, due to the relatively large inclination of the lamp, the distance between the LED and the inner light distribution mirror is inconsistent, resulting in poor lighting effect

The second case is that the circuit board is placed obliquely so that the distance between the LED and the inner light distribution mirror is kept as consistent as possible. The rate is lower, which in turn increases the cost of implementing this function

[0006] Therefore, it can be clearly seen that the better situation is to use the side-emitting method, but because in the side-emitting method, part of the LED light is blocked by the vertically placed circuit board, when a wider light-emitting area is required, There is a dark area when lighting due to the narrow irradiation range of the LED
