Laser lighting system and car laser lighting device thereof

Abstract

The invention discloses a laser lighting system and a car laser lighting device thereof, and relates to the field of car lighting. A laser light source, a wavelength selection component and a wavelength conversion component are included; the wavelength conversion component is arranged between the laser light source and the wavelength selection component; the laser light source is used for emittingtrigger laser light to the wavelength selection component; the wavelength conversion component is used for emitting illumination fluorescent light when receiving the trigger laser light; the wavelength selection component is used for reflecting the trigger laser light and the illumination fluorescent light with the wavelength less than or equal to a first preset wavelength when receiving the trigger laser light and the illumination fluorescent light and transmitting the illumination fluorescent light with the wavelength larger than a second preset wavelength; and the second preset wavelengthis larger than the first preset wavelength. By means of the laser lighting system and the car laser lighting device, the trigger laser light can form stable white light without repeated path conversion, the transmission path of the light is relatively simple, the loss of the light during transmission is small, and the luminous efficiency of the laser lighting system is increased.

Description

technical field [0001] The invention relates to the field of automotive lighting, in particular to a laser lighting system and an automotive laser lighting device. Background technique [0002] With the development of technology and the gradual maturity of transportation, people's daily travel is becoming more and more convenient. The headlight of the car is to the car as the human eye is to the human being. It is a crucial part of the car when driving at night. When the brightness of the headlight of the car is insufficient, it will greatly affect the user's performance when the car is driving. Security cannot bring users a reassuring experience. [0003] With the continuous development of lighting technology, car headlights have gradually developed from xenon lamps and halogen headlights to LED headlights, and some cars have also installed laser headlights, but because of the immaturity of laser technology and the high cost However, the popularity of laser headlights is ...

AI Technical Summary

Problems solved by technology

[0005] At present, when the existing laser headlights need to form stable white light, the conversion of the light wavelength and the multiple conversion of the light path can usually be realized by setting a rotating fluorescent wheel and multiple lens groups, but the above structure is relatively complicated, and the light In the transmission process, the loss is large, and the luminous efficiency of the laser headlight is low
