A light source module and a vehicle headlamp

Abstract

The invention relates to the field of optical technology, and discloses a light source module and a vehicle headlamp. The light source module includes a light source, a reflection device and a lens. The light source is arranged in the space surrounded by the reflection device, and the light-emitting surface of the light source faces the reflection surface of the reflection device. The reflection surface is used to reflect and guide the light output by the light source to the reflection device. The light outlet, the lens and the light outlet of the reflection device are arranged directly, and the focus of the incident light of the lens is set on the side of the lens close to the reflection device, and the focus of the reflected light of the second reflection section of the reflection device does not coincide with the focus of the incident light of the lens. . Through the above method, the present invention can increase the expansion angle of the light output by the light source module.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a light source module and a vehicle headlamp. Background technique [0002] The inventor of the present invention finds in long-term research invention process, and automobile headlamp refers to the illuminating device that is contained in automobile head both sides, is used for driving road at night. There are two-lamp system and four-lamp system. The lighting effect of headlights directly affects the operation and traffic safety of driving at night. Therefore, the traffic management departments of various countries in the world generally stipulate the lighting standards of automobile headlights in legal form to ensure the safety of night driving. [0003] However, due to the limitation of the internal structure of the automobile headlights widely used in the market, the extension angle of the low beam of the automobile headlights is small, and the area illuminated by the ligh...

AI Technical Summary

Problems solved by technology

[0003] However, due to the limitation of the internal structure of the automobile headlights widely used in the market, the extension angle of the low beam of the automobile headlights is small, and the area illuminated by the light is small, which will directly affect the driving of the car at night. The visible range of the driver will have a negative impact on the driving operation and driving safety of the driver at night.
