Embodiment 1
[0056] see Figure 1 to Figure 3 , the LED light source module 100 for hair removal according to the embodiment of the present invention is configured as a plurality of independent light-emitting areas 10 without overlapping areas, wherein:
[0057] Each light-emitting area 10 includes a plurality of LED chip groups 11;
[0058] Each LED chip set 11 includes a plurality of interconnected LED chips 111;
[0059] When emitting light at any time, the optical power density of each light-emitting area 10 is 20-60W / cm 2 .
[0060] In the LED light source module 100 for hair removal according to the embodiment of the present invention, the light-emitting area 10 can be controlled independently as an independent unit. Therefore, multiple light-emitting areas 10 can be controlled to emit light at different times, and a single light-emitting area 10 can be controlled within a unit of time. Controlling the heat generation and power consumption when emitting light is limited, which can...
Embodiment 2
[0097] Further, please combine figure 1 and figure 2 In this embodiment of the present invention, the LED chip groups 11 in the same light emitting area 10 further include a collinear area 112 for connecting the plurality of LED chips 111 in the adjacent LED chip groups 11 .
[0098] In the prior art, only the LED chips 111 are directly arranged on the substrate 20 , and then each LED chip 111 is directly connected in series, and no area dedicated to wiring and wiring is reserved on the substrate 20 . , in this way, the gap between each LED chip 111 cannot be accurately designed and calculated, and the effective connection between the LED chips 111 in different regions cannot be realized through the substrate 20, and the traces and wirings between the LED chips 111 are also The light emitting area of the plurality of LED chips 111 may be affected.
[0099] In the embodiment of the present invention, the plurality of LED chips 111 in each LED chip group 11 are arranged in ...
Embodiment 3
[0127] Further, in the embodiment of the present invention, the gap between the plurality of LED chips 111 is 0.01-1.0 mm.
[0128] It can be understood that the smaller the gap between the plurality of LED chips 111, the more compact the structure of the formed LED chip set 11, the light-emitting area 10 and the LED light source module 100 for hair removal, the LED light source module 100 for hair removal per unit light-emitting area The higher the ratio of the luminous area, the higher the radiated optical power density, and at the same time, the setting of the LED chip 111 and the production of the overall LED light source module 100 for hair removal are also more difficult. The heat dissipation burden of the group 100 is also greater.
[0129] The larger the gap between the plurality of LED chips 111, the looser the structure of the LED chip set 11, the light-emitting area 10 and the LED light source module 100 for hair removal. The smaller the area ratio, the smaller the...
