Color wheel fixing assembly

Abstract

The invention provides a color wheel fixing assembly, comprising a color wheel module and a fixing rack. The fixing rack is used for fixing the color wheel module, and is provided with a first joint part, a second joint part and a third joint part, wherein the connection lines of the first joint part, the second joint part and the third joint part form a triangle; the color wheel module comprises a motor, a rotating shaft and a color wheel; the color wheel is arranged on the rotating shaft, and the motor drives the rotating shaft to drive the color wheel to rotate, wherein the gravity center of the color wheel module is located on the rotating axis of the rotating shaft, and the first joint part, the second joint part and the third joint part are located on at least one plane perpendicular to the rotating axis of the rotating shaft; the first joint part and the second joint part are located on a first plane perpendicular to the rotating axis, the third joint part is located on a second plane perpendicular to the rotating axis, and the first plane and the second plane are not coplanar.

Description

[0001] This application is a divisional application of the original application whose filing date is February 12, 2015, the application number is 201510073228.8, and the invention title is "Color Wheel Fixing Assembly". Technical field [0002] The present invention relates to a color wheel module, and particularly relates to a color wheel fixing assembly that reduces vibration. Background technique [0003] Digital light processing (DLP) projection systems have become the mainstream products of projection systems in recent years due to their advantages of high brightness, high contrast, vivid colors, and fast response speed. Generally speaking, the projection light source is used together with the color wheel module, so that the light can be converted into colored light when passing through different color areas of the color wheel, such as red light, green light and blue light, etc., and then use Digital Micromirror Device , DMD) project colored light onto the screen to form an i...

Problems solved by technology

[0004] However, the fixing frame of the color wheel module is locked in the optical machine housing with screws, so when the color wheel module generates one-dimensional or multi-dimensional vibration, the shock wave will be transmitted to the optical machine housing through the fixing frame, causing the optical machine The machine or the entire projection system will vibrate. In this regard, the fixing structure of the color wheel module needs to be further improved to solve the vibration problem.
