Description

technical field [0001] The invention belongs to the technical field of lighting, in particular to a laser lighting device. Background technique [0002] Traditional LED fiber optic lighting usually uses white light and plastic optical fiber. Because plastic optical fiber has a large loss of light, the transmission distance is short, and because white light is mixed with light of various wavelengths, the loss of each wavelength in the optical fiber during transmission The difference leads to the shift of light color after reaching the application end, which limits the development of fiber optic lighting to a certain extent. [0003] The patent document with the authorized announcement number CN105222021B discloses a laser electroless lighting system. Although the laser LD is used to realize it through the quartz optical fiber, the light output part adopts reflective excitation, and the excitation device adopts ceramic phosphor powder. The obtained light efficiency is low, an...

[0002] Traditional LED fiber optic lighting usually uses white light and plastic optical fiber. Because plastic optical fiber has a large loss of light, the transmission distance is short, and because white light is mixed with light of various wavelengths, the loss of each wavelength in the optical fiber during transmission Different, leading to the shift of light color after reaching the application end, which limits the development of fiber optic lighting to a certain extent

[0003] The patent document with the authorized announcement number CN105222021B discloses a laser electroless lighting system. Although the laser LD is used to realize it through the quartz optical fiber, the light output part adopts reflective excitation, and the excitation device adopts ceramic phosphor powder. The light efficiency obtained is low, and the light reflected by the ceramic phosphor powder into the optical fiber will damage the laser LD and reduce the service life of the laser LD
