[0026] The light emitted by the light source is gathered through an optical system. Through multiple groups of optical lenses made of different materials and with different apertures, within a certain angle range, the requirement of relatively uniform distribution of light intensity is achieved.

[0027] Referring to Figure 2 , the light-gathering principle of the present invention is: after the light passes through each lens group, the divergent light forms the required light spot.

[0028] Referring to Figure 3 , the core technology of the present invention lies in: gathering as much light as possible emitted by the light source through the optical system. Analyzing at the observation position, in the case of a short focal length, the light forms a light spot with relatively uniform light intensity within the range of φ400mm, and the light angle is 15.8°, meeting the design requirements. Referring to Figure 3 , at the analysis surface position, the light is mainly concentrated within the range of φ400mm, proving that the optical concentration is good. In practical applications, the position of the light-receiving surface can be adjusted according to relevant requirements to control the diameter of the light spot and meet the transmission needs. Refer to the schematic diagram of the energy distribution on the analysis surface Figure 4 . Refer to the propagation situation of light passing through a surface at different incident angles in the case of a short focal length Figure 5 .

[0029] In the case of a long focal length, the light forms a light spot with relatively uniform light intensity within the range of φ900mm, and the light angle is 34.8°.
