Laser depilation device and depilation instrument

Abstract

The embodiment of the invention discloses a laser hair removal device and a laser hair removal instrument. The laser hair removal device comprises a laser emitting module. The laser emitting module comprises a substrate; light-emitting units which are located on one side of the substrate, wherein emergent light rays of part of the light-emitting units are overlapped to form emergent light spots of the laser hair removal device, and each light-emitting unit comprises a light-emitting chip located on one side of the substrate and a lens located on the light-emitting side of the light-emitting chip. In part of the light-emitting units, the optical axes of the light-emitting chips and the optical axes of the lenses are staggered. By reasonably arranging the positions of the light emitting units, good heat dissipation of the laser hair removal device is guaranteed, the position relation between the optical axis of the light emitting chip and the optical axis of the lens located on the light emitting side of the light emitting chip is adjusted, emergent light rays of the multiple light emitting units form uniform emergent light spots, and the hair removal effect of the laser hair removal device is guaranteed.

Description

technical field [0001] The embodiment of the present invention relates to optoelectronic technology, in particular to a laser hair removal device and a hair removal instrument. Background technique [0002] With the improvement of living standards, more and more people begin to pay attention to beauty and beauty. Laser hair removal device, also known as intense pulsed light hair removal device, is a kind of strong pulsed light beam that acts on the root of hair follicles and uses the thermal energy of its instant explosion. , Destroy the activity of hair follicles, so that the hair will no longer grow, and achieve a permanent hair removal effect, which has been loved by more and more women. [0003] At present, the laser hair removal device of the existing technology usually needs active air cooling or water cooling to dissipate heat, so as to ensure that the heat does not accumulate, and the laser hair removal device will not be burned due to overheating; and the high tempe...

Problems solved by technology

[0003] At present, the laser hair removal device of the existing technology usually needs active air cooling or water cooling to dissipate heat, so as to ensure that the heat does not accumulate, and the laser hair removal device will not be burned due to overheating; and the high temperature will correspondingly reduce the service life of the laser hair removal device, thereby affecting the output of light. effect, increasing maintenance and replacement costs

[0004] However, the active heat dissipation structure is complicated and the cost is high. How to ensure the heat dissipation effect of the laser hair removal instrument has become a research hotspot
