Document Type and Number:
Japanese Patent JP2016018594
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a light source device which includes a staircase mirror whose reflection surface has high posture accuracy and which is simple and cheap, and an electrical apparatus.SOLUTION: A light source device 10 includes: a plurality of light sources (LD1); a mirror member (staircase mirror 4); and a lens part (condenser lens 5). The staircase mirror 4 has a plurality of reflection surfaces 4r arranged stepwise for reflecting light (excitation light Lx) emitted from the plurality of light sources. The lens part (condenser lens 5) condenses the light reflected at the reflection surfaces 4r of the staircase mirror 4. The staircase mirror 4 is an integrally molded member. Thereby, as the staircase mirror 4 is integrally molded, occurrence of problems can be prevented which are caused by location accuracy of a strip mirror and an error in a joining step just like the conventional case where a plurality of strip mirrors are joined to a holding body and the plurality of strips are joined with each other. Also, a production process itself can be simplified, and increase of production cost of the light source device 10 can be suppressed.SELECTED DRAWING: Figure 1
