Light source module and automotive headlamp

Abstract

The invention relates to the field of optical technologies, and discloses a light source module and an automotive headlamp. The light source module comprises a light source, a reflecting device and alens, wherein the light source is arranged inside a space defined by the reflecting device; a luminous surface of the light source faces a reflecting surface of the reflecting device; the reflecting surface is used for reflecting light output by the light source and guiding the light to a light outlet of the reflecting device; the lens and the light outlet of the reflecting device are arranged oppositely; an incident light focus point of the lens is arranged on the side, close to the reflecting device, of the lens; and a reflecting light focus point on a second reflecting section of the reflecting device is not overlapped with the incident light focus point of the lens. Through the manner, the extension angle of light output by the light source module can be increased.

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...

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.
