The invention discloses an ultra-short-focus projector optical system color wheel structure cover, which comprises a color wheel structure cover, wherein the color wheel structure cover is internallyprovided with a high-speed heat conducting body, two ends of the internal part of the color wheel structure cover are provided with cooling fans respectively, and the color wheel structure cover is fixedly arranged at one side of a heating component. There are four groups of cooling fans, the left side of the color wheel structure cover is provided with two groups of cooling fans, and the right side of the color wheel structure cover is provided with two groups of cooling fans. The color wheel structure cover is made of an aluminum alloy. The heat dissipation scheme for the internal part of the color wheel structure cover is that a high-speed heat conducting medium is adopted, the high-speed heat conducting medium is distributed inside the color wheel structure cover, the heat inside the color wheel structure cover is quickly transferred to the surface of the color wheel structure cover by using high-efficiency heat conduction, and then the fans are utilized for cooling. The heat dissipation efficiency of the color wheel structure cover is effectively improved by applying the scheme to ultra-short-focus projection equipment, thereby preventing an excessively high temperature and reduction in working performance of a color wheel motor and service life caused by heat accumulation in the color wheel structure cover.
Description
technical field [0001] The invention relates to the technical field of the projection industry, in particular to a color wheel structure cover for the optical system of an ultra-short-focus projector. At the same time, the invention also relates to a heat dissipation solution for the color wheel structure cover of the optical system of the ultra-short-focus projector. Background technique [0002] In the DLP projection system, the input signal is converted into RGB data, and the data is sequentially written into the SRAM of the DMD. The light source is focused on the color wheel through the focusing lens, and the light passing through the color wheel is then imaged on the surface of the DMD. When the color wheel rotates, red, green, and blue light are sequentially incident on the DMD. The color wheel and video image are sequential, so when red light hits the DMD, the lens is tilted "on" according to the position and intensity of the red information that should be displayed,...
