一种投影机色轮结构及其散热方案A Projector Color Wheel Structure and Its Heat Dissipation Scheme

技术领域technical field

本发明涉及投影行业技术领域,具体为一种投影机色轮结构。同时本发明还涉及一种投影机色轮结构的散热方案。The invention relates to the technical field of the projection industry, in particular to a color wheel structure of a projector. At the same time, the invention also relates to a heat dissipation solution for the color wheel structure of the projector.

背景技术Background technique

在DLP投影系统中,输入信号被转化为RGB数据,数据按顺序写入DMD的SRAM,光源通过聚焦透镜聚焦在色轮上,通过色轮的光线然后成像在DMD的表面。当色轮旋转时,红、绿、蓝光顺序地入射在DMD上。色轮和视频图像是顺序进行的,所以当红光射到DMD上时,镜片按照红色信息应该显示的位置和强度倾斜到"开",绿色和蓝色光及视频信号亦是如此工作。人体视觉系统集中红、绿、蓝信息并看到一个全彩色图像。通过投影透镜,在DMD表面形成的图像可以被投影到一个大屏幕上。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, and the same works for green and blue light and video signals. The human visual system concentrates red, green, and blue information and sees a full-color image. Through the projection lens, the image formed on the DMD surface can be projected onto a large screen.

在该光学系统中,色轮的散热是一个重要的环节,光源发出的光经过汇聚成一束高能量光束,入射在色轮片上产生的热量,积聚在色轮结构罩里,如果色轮结构罩内部热量积累,导致内部温度超过色轮马达工作温度上限,则会损坏色轮马达,导致色轮马达性能下降或者减少色轮马达工作寿命。In this optical system, the heat dissipation of the color wheel is an important link. The light emitted by the light source is converged into a high-energy beam, and the heat generated by the incident on the color wheel sheet is accumulated in the color wheel structure cover. If the internal heat of the color wheel structure cover is accumulated, causing the internal temperature to exceed the upper limit of the working temperature of the color wheel motor, the color wheel motor will be damaged, resulting in a decrease in the performance of the color wheel motor or a reduction in the working life of the color wheel motor.

目前,超短焦投影机光学系统散热方案,针对色轮部位的散热方式,是采用风扇引导冷风流过色轮结构罩表面,利用冷风对色轮结构罩表面进行降温,把色轮结构罩表面热量带离色轮结构罩,实现冷热交换散热。At present, the heat dissipation scheme for the optical system of ultra-short-throw projectors is aimed at the heat dissipation method of the color wheel, which uses a fan to guide cold air to flow over the surface of the color wheel structure cover, and uses the cold air to cool the surface of the color wheel structure cover, and takes the heat from the surface of the color wheel structure cover away from the color wheel structure cover to achieve heat exchange and heat dissipation.

采用风冷散热的方式,散热效果的优劣取决于冷风经过色轮结构罩表面的流量,也就是说,只有保持相对高的风扇转速,才可以保证足够多的冷风流量和色轮结构罩表面的热量交换进行散热。这种方式的弊端是风扇不可能低速工作,而风扇高速工作时会产生大噪音,另外,利用风扇冷热交换散热,效率低。With the air-cooled heat dissipation method, the heat dissipation effect depends on the flow of cold air passing through the surface of the color wheel structure cover, that is to say, only by maintaining a relatively high fan speed can the sufficient flow of cold air flow and the heat exchange on the surface of the color wheel structure cover be guaranteed for heat dissipation. The disadvantage of this method is that it is impossible for the fan to work at a low speed, and when the fan works at a high speed, it will generate a lot of noise. In addition, the cooling and heat exchange of the fan is used for heat dissipation, and the efficiency is low.
