[0002] During the operation of the optical engine module in the projection equipment, the light source module will convert electric energy into light energy and heat energy during the operation process due to the limitation of physical characteristics. Influenced by the material of the light source chip, packaging material and process, the components in the light source module, such as the PN junction in the light-emitting diode light source, when the temperature rises, the light effect of the light source module usually decreases, the color temperature drifts, and the forward voltage (VF value) drift, and even the risk of burning electronic components

[0003] In the process of realizing the embodiment of the present invention, the inventors found that there are at least the following problems in the above related technologies: At present, in order to solve the problem that the light source in the projection light machine is easy to overheat, the existing solution usually chooses to reduce the heat generation of the light source, for example, reduce The number of light sources such as light-emitting diodes in the light source increases the area of ​​​​the light source panel, or directly uses cold light sources or fluorescent light sources with low thermal efficiency, etc. Most of them are improvements for light sources, but such improvements will bring light sources Problems such as unsatisfactory luminous effect and increased cost
