Color wheel group

Abstract

The invention relates to a color block group and an optical device, wherein, the color block group is fixed on a frame via a fixing element, comprising a motor, a filter element, a buffer element, and a positioning element, the positioning element is provided with a first hole, one side of the motor is axially arranged on the positioning element, the filter element is at another side of the motor, the buffer element is through the first hole, and the fixing element is through the buffer element to fix the positioning element and the frame. the invention comprises the buffer element or the buffer element group, passes the fixing element group through the buffer element to lock the positioning element and the frame, or passes the fixing element through the buffer element to fix the positioning element with the frame, therefore, the invention uses the buffer material to absorb and baffle the vibration generated by the motor and uses the fixing element or the positioning element to avoid transmitting the vibration to the frame via the fixing element. Therefore, the frame can avoid noise effectively, and the invention can improve the stability of the color block group and the optical elements in the frame, to improve service life.

Description

technical field [0001] The present invention relates to an optical element group, in particular to a color wheel group that can prevent the vibration of the motor from being transmitted to the projector casing, is not easy to generate noise, and relatively improves the overall stability of the color wheel group and the optical elements inside the casing. . Background technique [0002] Image projection system is one of the most popular sub-items in the current photoelectric industry, and the digital light processing (Digital Light Processing, DLP) projector in the current popular projection system adopts digital control and uses the principle of reflected light After the light source is collected, it is focused through the lens and then passed through the color filter of the red, blue and green three-color filter, and projected onto the digital micro-mirror device (Digital Micro-mirror Device, DMD). Since the digital micro-mirror device has many The tiny movable mirror cont...

Problems solved by technology

In this way, not only is it easy to cause noise, but the vibration of the housing 3 may also affect the normal operation of other optical components in the projector, and even cause the entire projector to resonate, thereby reducing the life of the product

[0005] It can be seen that the above-mentioned existing color wheel group obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general products do not have a suitable structure to solve the above-mentioned problems. This is obviously related. The problem that the industry is eager to solve
