US 9,039,255 B2 · Light source device, projector, and light source device fabrication method

Abstract

A light source device which can prevent the removal of light source elements of a light source device within a projector casing, a projector and a light source fabrication method are provided. An excitation light shining device 70 has a lens holding structure 79 and a light source holding structure 80 which are integrated together with excitation light sources held therebetween. The lens holding structure 79 has through holes 79f which first screw members 84 penetrate, and the light source holding structure 80 has screw holes 80h and screw holes 80k communicating with the screw holes 80h substantially at right angles. With the first screw members 84 penetrating the through holes 79f to be screwed into the screw holes 80h, screw thread portions of the first screw members 84 are pressed to be deformed plastically by distal end portions of the second screw members 85.

Dependent claims

A light source device comprising:

a light source element which is held between a first holding structure and a second holding structure, wherein
the first holding structure has a through hole which is formed so as to extend towards the second holding structure and which allows a first screw member to be put therethrough, wherein
the second holding structure has (a) a first screw hole which communicates with the through hole and into which a rod-shaped main body portion of the first screw member is screwed and (b) a second insertion hole which communicates with the first screw hole substantially at right angles and into which a second insertion member is inserted, and wherein
in a state in which that the first screw member is put through the through hole and screwed into the first screw hole, the second insertion member presses a screw thread portion of the main body portion of the first screw member so as to deform the screw thread portion plastically by a distal end portion of the second insertion member.

A light source device fabrication method for fabricating a light source device which holds a light source element between a first holding structure and a second holding structure comprising:

a first preparatory step of preparing in the first holding structure a through hole which is formed so as to extend towards the second holding structure and which allows a first screw member to be put therethrough;
a second preparatory step of preparing in the second holding structure (a) a first screw hole which communicates with the through hole and into which a rod-shaped main body portion of the first screw member is screwed and (b) a second insertion hole which communicates with the first screw hole substantially at right angles and into which a second insertion member is inserted;
a screwing step of allowing the first screw member to be put through the through hole to thereby be screwed into the first screw hole;
and
a plastic deformation step of inserting the second insertion member into the second insertion hole so that a distal end of the second insertion member presses a screw thread portion of the first screw member so as to plastically deform the screw thread portion.
