PROBLEM TO BE SOLVED: To provide a solid lighting device, compact, of light-weight, of low heat radiation, and with safety enhanced.SOLUTION: A solid lighting device has a light source part 10, a light guide part 20, and a light-emitting part 30. The light source part 10 has a semiconductor laser 11 and a drive circuit 12. Further, the light source part 10 releases a plurality of laser beams with a wavelength range of blue to blue-violet colors. The light guide part 20 has a plurality of light guide paths for guiding the respective plurality of laser beams. The light-emitting part 10 has a heat conductive part 34 having a first face, a wavelength conversion layer 32 installed at the center of the first face, and an optical part 30. Wavelength conversion light released from the wavelength conversion layer 32 absorbing the plurality of laser beams G1 and the plurality of laser beams are released from a top face of the optical part 30. |
