Title:
LIGHT SOURCE DEVICE AND LIGHTING DEVICE USING THE SAME
Document Type and Number:
Japanese Patent JP2016213109
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a light source device which is high in illumination efficiency in a normal state, and a lighting device using the same.SOLUTION: A light source device is constituted of: a laser diode element 1; a reflector 2 composed of a primary reflection face 21 and a secondary reflection face 22; a wavelength conversion member 3 which is arranged at the secondary reflection face 22 so as to penetrate it, converts a wavelength of a part of coherent light L1 as excitation light from the laser diode element 1, and emits non-coherent light L2 as primary diffusion light DL1 toward the primary reflection face 21 by mixing it with remaining light; a lens 4 which emits the non-coherent light L2 from the primary reflection face 21 and the secondary reflection face 22 of the reflector 2; a coherent light terminal-end processing part 5 which is arranged in a position above the primary reflection face 21 which opposes the laser diode element 1 via a position of the wavelength conversion member 3, and processes the terminal end of the coherent light L1 from the laser diode element 1; and a flap 6 which is composed of an irreversible shape memory alloy arranged at an opening OP of the coherent light terminal-end processing part 5.SELECTED DRAWING: Figure 1
