摘要:
The present invention provides a projection apparatus that includes a mirror element and a drive circuit for driving a laser light source for projecting an illumination light. The projection apparatus further includes mirror device for modulating the illumination light and a projection lens for projecting the modulated light from the mirror element. The mirror device is disposed on a device substrate and packaged in a package substrate made of a transparent silicon material with a metallic thermal transfer path connected to the device substrate and a cover glass covering the package substrate. The distance between the mirror and the bottom surface of the cover glass is larger than the focal length of the projection lens.
