LIGHT-EMITTING DEVICE FOR COSMETIC CARE Russian patent published in 2011 - IPC H01L33/00 A61N5/06 

FIELD: physics.

SUBSTANCE: light-emitting device for cosmetic care, comprising a portable main housing and a light-emitting unit placed at one end of the main housing to radiate light onto the surface of a living organism. The light-emitting unit comprises a light source and a lens through which the light passes. The light-emitting device for cosmetic care also has a light distribution control unit, having an output part between the lens of the light-emitting unit and the surface of the living organism, and an opaque part which covers the periphery of the output part and the light-emitting unit. The output part has optical elements through which light emitted by the light-emitting unit passes while preserving the amount of light. The light distribution control unit is held in the main housing with possibility of moving relative the lens in the direction in which the light-emitting unit emits light. The light distribution control unit additionally comprises slide guides on side surfaces of the opaque part, wherein the slide guides enable the light distribution control unit to slide in the direction of radiation of light and in the opposite direction.

EFFECT: invention provides an easy to use, safe, light-emitting device for cosmetic care, capable of preventing a drop in the amount of light emitted onto the surface of a living organism, without increasing the size of the device, and also capable of preventing contact between the surface of the living organism and the light-emitting unit and forming a gap between the light-emitting unit and the skin surface, which prevents leakage of the emitted light and increases safety.
