<P>PROBLEM TO BE SOLVED: To provide a headlight which is excellent in usability and achieved in size reduction and weight reduction. <P>SOLUTION: In the headlight 1 having a light-emitting device, the light-emitting device includes a light-emitting device having transistor lasers for emitting laser beams, an optical fiber 5 having an incident end 5b for receiving the laser beams emitted from the transistor lasers and an emission end 5a for emitting the laser beams incident from the incident end 5b, and a light-emitting section 7 for emitting light at a wavelength range of near infrared rays from visible light by receiving the laser beams emitted from the emission end 5a; a resin reflecting mirror 8 for forming light flux advancing into a designated three-dimensional angle by reflecting the light emitted from the light-emitting section 7; and a resin lens 12 which is a member for covering an opening formed in the advancing direction of the light flux and penetrated with the light flux. The transistor lasers are arranged outside a reflective space surrounded by the reflecting mirror 8 and the lens 12. Therefore, the headlight 1 is excellent in usability and can achieve the size reduction and weight reduction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
