Problems solved by technology

There are many parts and types in the lighting module of the prior art. On the one hand, the manufacturing error of the parts and the assembly error between the parts will affect the accuracy of the optical system, which will affect the lighting light shape. On the other hand, the shading plate Parts such as brackets and brackets also increase the cost of the lighting module and increase the difficulty of positioning and installation of the lighting module; moreover, the distance between the front and back of the light in the above-mentioned lighting system is longer, and the distance between the reflective element and the lens is longer, which increases the cost of the lighting module. The length of the lighting module is in sharp contradiction with the trend of more compact car lights in the future

Abstract

The invention relates to a vehicle lighting device, and discloses a vehicle lamp optical element which comprises a light passing part (2) and a light emitting part (3), the light passing part (2) comprises a light entering surface (25), a first reflecting surface (21) and a second reflecting surface (22), and the first reflecting surface (21) and the second reflecting surface (22) are oppositely arranged. Light received by the light entering surface (25) is reflected by the first reflecting surface (21) and the second reflecting surface (22) in sequence and then is emitted to the light emitting part (3). In addition, the invention further discloses a vehicle lamp module and a vehicle. The vehicle lamp optical element is miniaturized, and the integration degree is higher.

Description

technical field [0001] The present invention relates to a vehicle lighting device, in particular to a vehicle light optical element. In addition, the present invention also relates to a vehicle light module and a vehicle including the vehicle light optical element. Background technique [0002] In recent years, car lights and car light modules assembled in car lights have developed rapidly. From the early halogen lamps to the later xenon lamps, and now to the current LED and laser light sources, the car lights have become more intelligent. And the shape is also more differentiated. Among all kinds of car light sources, LED light source has gradually gained the attention of automobile manufacturers due to its excellent performance and low cost advantages. With the development of LED light source, its light distribution structure is also gradually developing. [0003] The lighting module with LED light source commonly used in the automobile lights in the prior art generally ...
