Optical modules and headlights

Abstract

The invention relates to an optical module and an automotive lamp. The optical module comprises an LED light source and a lens. The lens is located in front of the LED light source. A light exit face of the LED light source faces a light incident face of the lens. A light exit face of the lens is a non-rotational-symmetric curved face. The light incident face of the lens is a plane or curved face. The middle of the lens is thick, and the edge of the lens is thin. The lens achieves a converging function on light emitted by the LED light source, and the converging function of the edge of the lens on the light is stronger than that of the middle of the lens on the light. One or more optical modules are arranged in the same closed lamp body of the automotive lamp, and the optical modules are arranged linearly or in an array manner. A feasible optical and structure implementation scheme is provided for cooperatively achieving the unique automotive lamp appearance molding, the optical module and the automotive lamp are especially suitable for being applied to occasions compact in space structure layout, and balance between lamp space and light distribution requirements is achieved.

Description

technical field [0001] The invention relates to an optical module and a vehicle lamp using the optical module, belonging to the technical field of vehicle lights. Background technique [0002] Such as figure 1 , 2 As shown, the current implementation methods of vehicle front fog lamps mainly include: 1. Halogen bulb + reflector; 2. LED light source + reflector. The light distribution performance of the front fog lamp is realized by the combination of the bulb light source 1 and the reflector 2, and the combination of the LED light source 3 and the reflector 2 respectively. The working principle determines that these two types of optical modules occupy a relatively large space. In addition, the optical implementation method is single, so the constraints on the shape of the car lights are relatively large, and it is difficult to meet the increasingly complex lighting shape requirements. Contents of the invention [0003] The present invention aims to provide an optical mo...
