Miniature vehicle lamp module

Abstract

The invention provides a miniature automobile lamp module which comprises a lens, a primary optical element and a light source which are arranged from front to back, the light source is fixed to a circuit board, a connecting part is arranged on the primary optical element, and a lens connecting part is arranged on the lens. And the primary optical element is respectively in direct positioning connection with the lens connecting part and the circuit board through the connecting part. The beneficial effects of the invention are that the optical system is high in precision, the lens and the circuit board are directly connected with the primary optical element in a positioning manner, repeated assembly errors are reduced, and the precision of the optical system can be guaranteed just through guaranteeing the relative position precision of the three parts; the structure is compact and small, the size of each optical element can be reduced, and the size of the whole automobile lamp module isreduced; the dispersion phenomenon is weakened by cutting off the upper end and the lower end of an existing lens.

Description

technical field [0001] The invention relates to the technical field of vehicle lighting, in particular to a miniature vehicle lamp module. Background technique [0002] A car light module generally refers to a device that has a lens or an equivalent structural part as the final light-emitting element and is used for the low beam or high beam lighting of the car headlight. In recent years, the development of the automobile industry has gradually matured and stabilized, and the types of car light modules have become more and more diverse. More and more requirements have been put forward for the comprehensive performance of car light modules, such as the near The uniformity of light or high beam shape, the visibility of low beam, heat dissipation performance, the brightness of high beam, and the structure, weight and volume of the module, etc. [0003] Chinese invention patent CN106122870B discloses an LED light source far and near light integrated car lamp module, which mainl...

AI Technical Summary

Problems solved by technology

However, if it is used as an auxiliary low beam module, it does not need high illuminance. It only needs to obtain a light shape with uniform illuminance and wide spread. Therefore, the volume of the light module will cause waste of space and cost.

[0005] 2. Low precision of optical system

In this car light module, the primary optical element and the radiator are positioned and installed first, and then the lens and the lens bracket are positioned and installed with the radiator or positioned and installed with the radiator through a transition bracket. The method causes multiple assembly errors between the primary optical element and the lens, and it is difficult to guarantee the manufacturing accuracy and positioning and installation accuracy, which makes the optical system less accurate

[0006] 3. The phenomenon of dispersion is serious. The thickness of the upper and lower ends of the lens used in the car light module is very thin, and the light that hits the upper and lower ends of the lens will be greatly deflected, resulting in serious dispersion, which does not meet the requirements of regulations.
