For example, "connected" can be a wall-mounted connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection.

[0034] Referring to Figures 1 - 5 , this embodiment provides a light source assembly of an optical skin care lamp, including: a substrate, a light emitting unit 1 arranged in an array on the substrate, and a reflecting cup 2 covering each light emitting unit 1;

[0035] The light emitting unit 1 includes five LED lamp beads, and the reflecting cup 2 is a regular hexagon; the reflecting cups 2 in the same row are connected left and right, and the reflecting cups 2 in adjacent rows are staggered so that the reflecting cups 2 are arranged in a honeycomb shape on the substrate; the light emitting unit 1 includes a plurality of packaged LED chips.

[0036] This embodiment provides a light source assembly of an optical skin care lamp. The LED chips are combined into a plurality of light emitting units 1, and then a regular hexagon reflecting cup 2 is arranged outside each light emitting unit 1, and a plurality of reflecting cups 2 are arranged in the shape of a honeycomb, so that the light emitted by the light emitting unit 1 forms a beam of parallel light after passing through the reflecting cup 2 and irradiates on the skin surface of the user. Since each beam of light is parallel and there is no intersecting area between them, the irradiated light in each area is relatively uniform.

[0037] Specifically, the light-emitting unit 1 includes six packaged LED chips, five of which are arranged at the five vertices of a regular pentagon, and the other is arranged at the center of the regular pentagon. Moreover, the center of the regular pentagon coincides with the center of the reflector cup 2. These settings are all to make the light emitted by the LED chip more parallel, so as not to cause the problem of local brightness being greater than the brightness of other areas.

[0038] In this embodiment, the light emitting angle of the packaged LED chip is 10°-60°. To achieve the above light emitting angle, the packaged LED chip includes a light emitting chip, a pin, a bracket, a packaging glue and a gold wire; the light emitting chip is packaged on the bracket by the packaging glue, and is conductively connected to the pin of the bracket by the gold wire, and the pin is inserted on the substrate. The purpose of controlling the light emitting angle and light emitting efficiency can be achieved by selecting the transmittance and refractive index of the packaging glue. The purpose of controlling the light emitting angle can also be achieved by controlling the installation position of the LED chip.

[0039] In this embodiment, the side wall of the reflector cup 2 is inclined inwardly. The angle of the inward inclination of the side wall of the reflector cup 2 is 1-10 degrees. In this way, the light can be emitted from the opening of the reflector cup 2 after being reflected by the bevel.

[0040] Furthermore, in order to further utilize the light emitted by the LED chip, the surface of the substrate is covered with a reflective film. The reflective film is an aluminum-plated film or a PET composite film. In this way, some of the light emitted by the LED chip that propagates backward can also be reflected by the reflective film and emitted from the opening of the reflective cup 2, thereby avoiding the waste of light.

[0041] In this embodiment, the light emitting unit 1 is divided into a blue light emitting unit 1, a yellow light emitting unit 1, a red light emitting unit 1 and an infrared light emitting unit 1 according to the light emission wavelength;

[0042] The wavelength of the blue light is 450-480nm, the wavelength of the yellow light is 560-600nm, the wavelength of the red light is 620-670nm, and the wavelength of the infrared light is 810-1100nm.

[0043] This embodiment also provides an optical skin care lamp equipped with the light source assembly described above.

[0044] Utilize 4 different wavelengths of light to match different frequencies and combine them into different formulas to obtain different functions. The functions are as follows: whitening and lightening, skin rejuvenation and brightening, anti-wrinkle and lightening, firming and elasticity, soothing and repairing.

[0045] The types of light-emitting diodes (LEDs) that are lit and the duty cycle of the lit LEDs during the lighting cycle for each function are described below. It should be noted that if two colors of light-emitting units 1 need to be lit in a function, these two light-emitting units 1 are lit periodically, and the duty cycle refers to the duty cycle of the light-emitting unit 1 of that color within its own lighting cycle.
