Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, in an example of utility model, comprise radiator fan 1, heat radiation scale 2, integrated high-power infrared LED light source 3, diffusion sheet 4, prefocus cup 5, collector lens 6, drive circuit and shell. Wherein radiator fan 1 and integrated high-power infrared LED light source 3 are fixed on heat radiation scale 2, and heat radiation scale 2 is fixed on shell; Diffusion sheet 4 is fixed on integrated high-power LED light source 3 surfaces; Prefocus cup 5 and collector lens 6 are fixed together, and prefocus cup 5 is fixed on shell by limited screw; Heat radiation scale 2, integrated high-power infrared LED light source 3, diffusion sheet 4, the center of prefocus cup 5 and collector lens 6 is on same straight line.
