Abstract:
A head lamp for a vehicle includes a laser light source module. The laser light source module comprises a laser diode generating a laser beam. A phosphor is mounted in front of the laser diode to react to light from the laser diode to output white light. A short wave pass filter is coupled with the phosphor to transmit a laser beam from the laser diode to the phosphor and retro-reflect light scattered in remaining directions avoiding a light emitting surface of the phosphor among the laser beam incident on the phosphor to the phosphor.

Provided is a laser optic module including: a laser light source which generates laser light; a beam guide which includes a light path whose side wall is a reflective surface to introduce the laser light into the light path to guide the laser light; and a fluorescent substance which is provided at a point where the light path of the beam guide ends and emits fluorescence by the laser light, in which a width of the light path is formed by a full width at half maximum (FWHM) of the laser light in a position where the laser light is incident onto the fluorescent substance. Therefore, the laser light is directly used to improve luminance efficiency and reduce a size by adopting a simple structure.
