[0002] With the pursuit of high-quality life, outdoor activities are increasingly diverse, and outdoor cinemas, open-air speeches and various temporary public display activities are increasingly favored by the public. The smooth development of these activities highly depends on high-performance audio-visual equipment, especially projection equipment that can stably operate in complex outdoor environments. Among many outdoor projection equipment, single-LCD projectors have been widely used due to their low cost and simple optical structure.
[0003] However, the current single-LCD projectors on the market still have some shortcomings in actual use. The heat-generating components such as light machines and circuit boards are tightly integrated with the heat dissipation system in a small space, making it difficult to effectively dissipate heat, and the internal temperature of the equipment continues to rise. This not only reduces the working efficiency of electronic components, but also greatly shortens their service life. More importantly, in order to achieve ventilation and heat dissipation, the waterproof performance is often sacrificed, which cannot adapt to humid outdoor environments such as rainy days, greatly limiting their application in complex outdoor scenarios.
