Device and method for converting blue light of blue laser diode to white light

摘要

The present invention discloses a laser lamp white converting device and a converting method capable of converting blue light from a blue laser diode into white light. The conversion device of the present invention is installed on the rightmost side of the laser lamp white conversion device, the outside air circulation fan for sucking or discharging outside air; A laser diode unit emitting white light; A heat sink installed at the bottom of the laser diode unit to discharge heat emitted from the laser diode unit; A diffusion lens unit formed on a top of the laser diode unit and formed in a semicircular shape to diffuse white light emitted from the laser diode unit; A lampshade reflector installed on an upper portion of the diffusion lens unit to reflect white laser light diffused from the diffusion lens unit; A temperature sensor spaced apart in front of the heat sink; And a convex lens unit that forms a front end of the laser lamp conversion device installed in front of the temperature sensor and focuses irradiating the white laser light reflected from the reflector to realize the blue light of a laser diode that has never been realized as white light, and thus the head of a car. It is possible to realize a white light source that is much more efficient than a conventional fluorescent lamp or LED in a lamp, home or office.
