摘要： A headlamp of an embodiment of this invention includes a laser element, a light emitting section, and a parabolic mirror. A part of the parabolic mirror is provided so as to face an upper surface of the light emitting section, which upper surface has a larger area than that of a side surface of the light emitting section. The light emitting section emits fluorescence in such a manner that distribution of the fluorescence corresponds to the Lambertian distribution.

摘要： A headlamp of one embodiment of this invention includes a laser element for emitting a laser beam, a light emitting section for generating fluorescence upon receiving the laser beam, and a reflecting mirror for projecting the fluorescence. Distribution of the fluorescence emitted by the light emitting section corresponds to Lambertian distribution, and an incident angle of the laser beam with respect to an excitation light irradiated surface, which is a surface of the light emitting section irradiated with the laser beam, is set so that use efficiency of the fluorescence emitted by the light emitting section is increased.

摘要： A light projection unit capable of improving light use efficiency is provided. This light projection unit includes: a fluorescent member that includes an illuminated surface to which laser light is directed, converts at least part of the laser light into fluorescent light and outputs the fluorescent light from chiefly the illuminated surface; and a reflection member that includes a first reflection surface which reflects the fluorescent light output from the fluorescent member. The illuminated surface of the fluorescent member is inclined with respect to a predetermined direction in such a way that the illuminated surface faces in a direction opposite to a light projection direction.
