Claim Text:
1. A light projection unit comprising: a light guiding member having a light entering surface and a light exiting surface, the light entering surface being configured to receive laser light, and the light exiting surface being configured to emit the laser light; a fluorescent member comprising a fluorescent material and having a irradiation surface configured to receive the laser light emitted from the light exiting surface of the light guiding member and to emit fluorescent light as a result of conversion of the laser light by the fluorescent material; and a light projector configured to project the fluorescent light emitted from the irradiation surface of the fluorescent member in a predetermined direction, wherein the light guiding member is so configured that the laser light emitted from the light exiting surface and prior to being received by the fluorescent member does not have a light intensity peak of a Gaussian distribution, and the light entering surface is a planar surface, and the light exiting surface is a planar surface.
