Abstract

The invention provides a projecting apparatus and a color wheel module used in the projecting apparatus, wherein, the projecting apparatus comprises a bare engine and a color wheel module which comprises a color wheel, a connecting device and a support frame, wherein, the color wheel is connected with the support frame which comprises a first permanent seat and a second permanent seat; the first permanent seat and the second permanent seat are connected to the bare machine through the connecting device, and the first permanent seat, relative to the center of the color wheel, is arranged opposite to the second permanent seat positively or obliquely with a certain angle.

Description

technical field [0001] The invention relates to a color wheel module used in a projection device and the projection device, in particular to a module design for stably fixing the color wheel module on the projection device. Background technique [0002] Currently, digital light processing (DLP) technology is commonly used in digital projection devices as a method for generating digital images. This technology is mainly developed based on the Micro Electro Mechanical System (MEMS) of the Digital Micromirror Device (DMD) and other peripheral optical components. Please refer to FIG. 1 , which shows an exploded view of main components of a conventional DLP projection device 100 . The DLP projection device 100 includes a light source 102 , a color wheel 104 , a light guide 106 , a lens set 108 , a DMD 110 , and a projection lens 112 . Wherein, according to the forward direction of light, the entire projection device 100 can be divided into two major systems, one is the light so...
