Title:
LIGHT SOURCE DEVICE AND OPTICAL MEMBER
Document Type and Number:
Japanese Patent JP2015166754
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a light source device that suppresses positional deviation of an optical member.SOLUTION: A light source device 10 includes a light source unit 11 that emits light, an optical member 18 having a planar incident surface 24a where the light emitted from the light source unit 11 enters, and a base part 12a having a planar surface 13 where the optical member 18 is adhered with an adhesive 26. The optical member 18 includes an adhesion surface 21 to be adhered to the surface 13 of the base part 12a with the adhesive 26; and the adhesive surface 21 is formed into a curved surface to give a constant distance from a reference line L1 in a direction parallel to or inclined to intersect the incident surface 24a. The optical member 18 is adhered to the surface 13 of the base part 12a in such a manner that the reference line L1 is parallel to the surface 13 of the base part 12a.
