Abstract

The invention relates to the technical field of illumination, in particular to a light source capable of adjusting a color temperature and a light source module and a headlamp adopting the light source. The light source capable of adjusting the color temperature comprises a first light source for emitting a red light ray, a second light source for emitting a green light ray, a third light source for emitting a blue light ray, and a light ray collecting device; and the light ray collecting device collects the light rays emitted by the first light source, the second light source and the third light source, and mixes the light rays to form mixed light rays. In the scheme, the light source comprises the first light source for emitting the red light ray, the second light source for emitting the green light ray and the third light source for emitting the blue light ray; the light ray collecting device collects the light rays emitted by the first light source, the second light source and the third light source, and mixes the light rays to form the mixed light rays; the color temperature adjustment of the mixed light rays is realized through controlling the light emitting strengths of the first light source, the second light source and the third light source; and the light source capable of adjusting the color temperature is suitable for illumination demands of various temperature temperatures.

Description

technical field [0001] The invention relates to the technical field of automobile lighting, in particular to a light source with adjustable color temperature, a light source assembly and a headlamp using the light source. Background technique [0002] In the field of automotive lighting technology, headlights are mainly used to illuminate the road ahead of the vehicle when the ambient light is insufficient during driving to ensure the safety of driving. [0003] Due to the complex and diverse road environment and climate environment of the car, in order to ensure that the headlights can be reliably illuminated under various environmental conditions, the current headlights usually include low beams and high beams. The road is smooth, and high beams are used when there is no meeting of vehicles, so that the driver has a farther and wider vision and ensures the safety of the vehicle at high speed; [0004] In the case of poor road conditions, or in the process of meeting cars,...
