Abstract

In a light projecting apparatus including a laser light source, a light projecting apparatus 1 is divided into a laser-light-source module 10 and a light-projecting optical module 30. In the laser-light-source module 10, laser beams from a plurality of laser light sources 15 are combined by a beam combiner 18. The laser-light-source module 10 and the light-projecting optical module 30 are connected to each other by an optical fiber in a cable 40. A laser beam formed by the beam combiner 18 is transmitted through the optical fiber to the light-projecting optical module 30, received by a fiber receptacle 31, and projected. In the laser-light-source module 10, a fiber-breakage countermeasure section 20 that detects breakage of the optical fiber and takes countermeasures against the breakage is disposed.
