[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "top / bottom end", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0036] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "provided with", "sheathed / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a wall-mounted connection, a detachable connection, or an integral connection, can be a mechanical connection, can be an electrical connection, can be directly connected, or can be indirectly connected through an intermediate medium, and can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0037] 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 sheathed outside each light emitting unit 1;

[0038] The light-emitting unit 1 includes five LED lamp beads, and the reflecting cup 2 is regular hexagon-shaped; 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.

[0039] This embodiment provides a light source assembly for an optical skin care lamp. LED chips are combined into a plurality of light-emitting units 1, and then a regular hexagon-shaped reflecting cup 2 is arranged outside each light-emitting unit 1. 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 irradiation light in each area is relatively uniform.

[0040] 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 reflecting cup 2. These settings are all to make the light emitted by the LED chips more parallel and avoid the problem that the local brightness is greater than the brightness of the remaining areas.

[0041] 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, pins, a bracket, encapsulating glue, and gold wires; the light-emitting chip is encapsulated on the bracket by the encapsulating glue and is electrically connected to the pins of the bracket through the gold wires, and the pins are inserted into the substrate. By selecting the transmittance and refractive index of the encapsulating glue, the purpose of controlling the light-emitting angle and light-emitting efficiency can be achieved. The purpose of controlling the light-emitting angle can also be achieved by controlling the installation position of the LED chip.

[0042] In this embodiment, the side wall of the reflecting cup 2 inclines inward. The angle of the inward inclination of the side wall of the reflecting cup 2 is 1-10°. This can make the light pass through the inclined side and be emitted from the opening of the reflecting cup 2.

[0043] Moreover, in order to further utilize all the light emitted by the LED chips, the surface of the substrate is covered with a reflecting film. The reflecting film is an aluminized film or a PET composite film. In this way, some of the light emitted by the LED chips and propagating backward can also be reflected by the reflecting film and be emitted from the opening of the reflecting cup 2, avoiding the waste of light.

[0044] In this embodiment, the light-emitting units 1 are divided into blue-violet light-emitting units 1, blue light-emitting units 1, yellow light-emitting units 1, red light-emitting units 1, and infrared light-emitting units 1 according to the light-emitting wavelength;

[0045] The wavelength of the blue-violet light is 400 - 430 nm, the wavelength of the blue light is 450 - 480 nm, the wavelength of the yellow light is 560 - 600 nm, the wavelength of the red light is 620 - 670 nm, and the wavelength of the infrared light is 810 - 1100 nm.

[0046] This embodiment also provides an optical skin care lamp equipped with the light source assembly described above.

[0047] Five different wavelengths of light are used to match different frequencies, and different formulas are combined to obtain different functions, as follows: soothing and repairing, locking in moisture, brightening the skin tone, reducing wrinkles and anti-aging, resisting early aging, clearing acne and fading marks, and shrinking pores.

[0048] In the following text, the types of illuminated lamp beads in each function and the duty cycle of the illuminated lamp beads during the illumination period will be described. It should be noted that if two colors of light-emitting units 1 need to be illuminated in a function, these two light-emitting units 1 are illuminated periodically respectively, and the duty cycle refers to the duty cycle of the light-emitting unit 1 of this color during its own illumination period.
