Title:
LASER LIGHTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/134267
Kind Code:
A1
Abstract:
Provided is a laser lighting device (20), comprising: a lamp post (25) and a lamp cover (26); a laser source module (21) for emitting the laser; an adjustable reflective component (22) arranged in the lamp post (25) for receiving the laser and adjusting an exit direction of the laser; a wavelength conversion device (27) located on an inner wall of the lamp cover (26) for receiving the laser and for absorbing part of the laser to form an converted light, wherein an illumination light is formed with the converted light and the laser which is not absorbed by the wavelength conversion device (27); a temperature detecting device (23) for detecting position information of a laser spot on the wavelength conversion device (27) or the temperature detecting device (23), and feeding the position information to the adjustable reflective component (22), wherein the adjustable reflective component (22) adjusts the exit direction of the laser according to the position information so as to calibrate and adjust the position of the laser spot on the temperature detecting device (23). The laser lighting device of the present invention enables the laser to be accurately incident on the wavelength conversion device (27) to form the illumination light, realizing automatic adjustment of the laser lighting device (20).
