Abstract

The invention discloses a positioning system for an optical module for an automobile lamp. The positioning system comprises the optical module (1), an LED panel (2) and an installing bracket (3). The positioning system is characterized in that the LED panel (2) is arranged below the optical module (1), the optical module (1) and the LED panel (2) form a small detachable installing assembly (7), and the small detachable installing assembly (7) is directly positioned and installed on the installing bracket (3) through positioning sleeves. According to the positioning system, the LED panel (2) and the optical module (1) are directly positioned through positioning pins and pre-fixed through hooks, the optical module (1) and the LED panel (2) are directly positioned, therefore, the position precision of the optical module (1) and the LED panel (2) is relatively high, the assembling error is reduced, and the positioning precision of an optical system is improved.

Description

technical field [0001] The present invention relates to the design of an optical module, in particular, the present invention relates to a design of an optical module in a car lamp, the design of the optical module in a car lamp can be used for an optical positioning system in a car light, and the optical positioning system in a car light The optical positioning system in the lamp has high assembly accuracy. Background technique [0002] At present, in the design of car lights, LEDs are generally used as light sources. LED light sources have the advantages of long life, wide brightness range, and adaptability to various car light shapes. As a mandatory part of the regulations, the car lights must meet the light distribution value specified by the regulations for each function. In order to ensure the reliability and uniqueness of the light distribution of the actual parts, the design needs to ensure the position of the LED and the positioning accuracy of the optical parts. ...
