Title:
PROJECTION DEVICE
Document Type and Number:
Japanese Patent JP2009288469
Kind Code:
A
Abstract:

To solve the problem that it is difficult to reduce the size and increase heat radiation performance simultaneously in a high-luminance projection device.

By arranging laser beam sources respectively on a movable part and a non-movable part of a base comprising the movable part and the non-movable part, and moving the movable part when the projection device is used, the heat radiation performance is improved. Since the laser beam source moves simultaneously with the movable part, an optical path is secured by an optical fiber so that an optical axis may not be misaligned.
