Title:
光源デバイス及び光源装置
Document Type and Number:
Japanese Patent JP6596817
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a light source device which can suppress generation of residual stress during joining, thereby maintaining high output over a long period.SOLUTION: A light source device 4 includes: a light emitting member 16 including a two-dimensional light emitting elements array 14 where a plurality of light-emitting elements are arranged; and an optical member 20 which includes a two-dimensional light-emitting elements array 18 where a plurality of optical elements arranged respectively on an optical path of light emitted by the light-emitting elements are arranged, and is arranged opposite to the light-emitting member 16. A laser beam is emitted by a light-emitting area 14a where the light-emitting elements array 14 is present. The light emitted by the light-emitting elements are collimated by the lens array 18 for each light-emitting element. Both the light-emitting member 16 and the optical member 20 are fixed by a positioning part 22 which is provided between the light-emitting member 16 and the optical member 20 and regulates movement in a direction (X direction) parallel to a surface opposite to both members between the light-emitting member 16 and the optical member 20 and movement in a direction (Y direction) approaching to each other. The positioning part 22 is located at a central part (herein, the center) of the optical member 20.SELECTED DRAWING: Figure 2
