Laser resolves, and when blue light spoke brightness reaches 2 classes as defined in standard or 3 class, can be made to human eye in shorter time or moment
Maximum to the injury of human eye at the shortwave blue light between injury, especially 400-480nm, usually we can control it and pacify
In congruent grade, still, it is contemplated that the possible failure of emergency case and laser diode of actual use, it is necessary to which blue light detection is installed
Feedback device, to monitor in real time and photo-biological security protection.
Invention content
To solve the problems, such as blue light injury that RGB laser may will produce, the present invention provides a kind of for RGB laser car lights
Blue light detects feedback device, to provide safety guarantee as the car light of light source using RGB laser.
