[0052] Through the design, when the LCD screen and the front lens module 5 need to be replaced and maintained, the light machine top cover 4 does not need to be separated from the light machine chamber box 1 as a whole, and only the split cover 420 needs to be opened relative to the light machine top cover 4, so that dust in the external environment can be greatly reduced from entering the inner cavity of the light machine chamber box 1, causing dirt and affecting the later use of the projector.

[0053] Please refer to Figure 4 and Figure 5 The light source module 3 is provided with a threaded hole A, and the light machine top cover 4 is provided with a connecting hole B corresponding to the threaded hole A, and the light machine top cover 4 is connected with the light source module 3 by screwing the connecting hole B and the threaded hole A.
