Abstract

The invention provides a color wheel module and a projector. The color wheel module comprises a rotating unit, and is characterized in that the rotating unit comprises a body, a first portion and a second portion, the first portion is provided with a first outer surface and a boss, the boss protrudes out of the first outer surface, the boss is provided with a position marker, the second portion is provided with a second outer surface and a run-through abdicating space, the boss is located in the abdicating space when the first portion is matched with the second portion, and the position marker is exposed, so that the boss is positioned by the abdicating space, thus the position marker is positioned, and accurate alignment of the position marker is realized.

Description

technical field [0001] The invention relates to a projector, in particular to a color wheel module of the projector. Background technique [0002] DLP projector technology is a fully digital reflective projection technology. It is characterized above all by digital superiority. The adoption of digital technology improves the gray level of the image, eliminates the noise of the image, stabilizes the picture quality, and makes the digital image very accurate. Second is the reflex advantage. The application of the reflective DMD device greatly improves the total light efficiency of the imaging device, and the contrast and brightness uniformity are excellent. DLP projectors have high definition, uniform picture, sharp, delicate, natural and lifelike colors, three-chip projectors can achieve high brightness, and can be zoomed at will, which is very convenient to adjust. [0003] The working principle of the DLP projection device is to filter the light beam emitted by the ligh...
