Illuminating device and projector device to be mounted into electronic apparatus
First Claim
1. A projector device to be mounted in an electronic apparatus, comprising:
- a first member constituted of a thermally conductive material, at which a light emitting device is disposed;
a light modulating member that modulates light originating from the light emitting device;
a projection optical system that projects an image formed with the light modulated by the light modulating member;
a second member constituted of a material with a lower level of thermal conductivity compared to the first member, at which the first member and the light modulating member are disposed; and
a third member constituted of a material with a high level of thermal conductivity compared to the second member, that supports the second member and the projection optical system as an integrated unit and comes into surface contact with the first member.

Abstract
A projector module adopts a structure having an optical image forming block and an optical block integrated via a locking member. The optical image forming block adopts a structure achieved by disposing an aluminum substrate at which an LED is mounted and a liquid crystal panel in a casing constituted with a plastic material having low thermal conductivity. The locking member is formed by bending a metal sheet through a sheet metal bending process and the locking member is set in surface contact with the substrate. The optical block adopts a structure achieved by disposing a PBS and a reflecting member at the casing constituted with a plastic material having low thermal conductivity with a quarter-wave plate disposed at the boundary of the two members.
