Abstract
Official abstract text for this publication.
A laser optical system for a head lamp may include a laser diode emitting light, a PCB substrate to which the laser diode is attached, the PCB substrate controlling supply of current to the laser diode, a fluorescent body located in front of the laser diode, reacting with the light emitted from the laser diode and thereby outputting white light, a guide path located in front of the laser diode and guiding light, which is outputted from the laser diode, to the fluorescent body, and an internal reflecting surface located between the fluorescent body and the guide path and connected to the guide path, the internal reflecting surface reflecting light, which has been incident on the fluorescent body and scattered backwards, to the fluorescent body.
