Abstract

The invention belongs to the field of automobile lamp illumination and relates to a headlamp module. The headlamp module can have a high beam function and a low beam function at the same time, can generate various high beams with different brightness and anti-dazzling light types through the adjustable transmissivity of a light shielding plate, can be suitable for different driving conditions by adjusting the color of the light shielding plate and changing the color temperature of emergent light. The headlamp module comprises a shading plate (1), a projection lens (2), a light source (3), a reflector (4) and a radiator (5); the light source (3) is installed on the radiator (5); the reflector (4) is installed above the radiator (5); the projection lens (2) is installed on the radiator (5) through a support (8); and the shading plate (1) is installed on the support (8) and located at the front focus of the projection lens (2).

Description

technical field

[0001] The invention belongs to the field of automobile lamp lighting, in particular to a headlamp module. Background technique

[0002] As the main lighting fixture of the car, the car headlight is of great significance to the safe driving of the car. In terms of design principles, headlights can be divided into reflective type and projection type. Projection type headlights can design the far and near light functions in one module. There are two main design principles. One is to use opaque shading Place the plate at the front focus of the lens to generate the low beam cut-off line, and then cooperate with the solenoid valve to control the movement of the visor to realize the switching of far and near beams, but this solution will increase the size and weight of the module ; In the second scheme, the low beam principle remains unchanged, but the high beam function does not depend on the solenoid valve. The light source is used to illuminate the area above t...
