The overall visual light source has a simple structure, saves costs and improves the assembly efficiency.

[0029] During operation, light is emitted by the LED light board 60. Then the light passes through the diffuser plate 70. After passing through the diffuser plate 70, it can be transformed into a diffused light source, thereby providing a better diffusing effect and obtaining a uniform and stable diffused light irradiation area. Then the diffused light irradiates on the semi-transmissive and semi-reflective beam splitter 80. After passing through the semi-transmissive and semi-reflective beam splitter 80, part of the incident light energy can be reflected by the semi-transmissive and semi-reflective beam splitter 80, with a relatively small amount absorbed, and the remaining energy is transmitted. Then the light passing through the semi-transmissive and semi-reflective beam splitter 80 is emitted through the focusing lens 50.

[0030] Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.
