The lamp panel 211 can be controlled to emit light with a plurality of different wavelengths, wherein one or more light with different wavelengths can be emitted after being arranged and combined.

In this embodiment, the light source board 211 includes a plurality of light beads 212 arranged in an array, and each light bead 212 includes 4 kinds of LED chips, which are respectively a 460nm blue LED, a 630nm red LED, a 850nm near-red LED, and a 590nm yellow LED; blue light with the wavelength of 460nm can eliminate anaerobic propionibacterium acnes and reduce sebum secretion, so that the effects of acne removal and oil control are achieved; the yellow light with 590nm can promote lymph toxin expelling and circulation, effectively decompose and inhibit pigmentation of the skin bottom layer; the red light of 630nm can excite the activity of mitochondrial hydrogenase of human tissues and promote the generation of collagen and elastin; the 850nm infrared light helps to eliminate edema, stimulate cell metabolism, blood circulation, and regrowth of collagen. The light emitted by the four LED lamps can be arranged and combined into 7 light modes: red, yellow, blue, violet (red+blue), red+near infrared, white (red+yellow+blue) +near infrared; the modes can be switched by pressing a key for a short time.

The light emitting assembly 2 further comprises a ranging mechanism 22, wherein the ranging mechanism 22 is a laser ranging element; the distance measuring mechanism 22 is used for detecting the distance between the light-emitting panel 21 and the user so as to at least control the light-emitting panel 21 to emit light. Specifically, the distance measuring mechanism 22 is configured to detect a distance between the light emitting panel 21 and the user to control at least the light emitting intensity of the light emitting panel 21 or control the light emitting panel 21 to emit a light signal. The laser of the laser ranging element is emitted from the generator, passes through the laser detection window of the light-emitting component 2, and is reflected back along the original route after reaching the object, the distance is captured and calculated by the ranging module, and finally the distance value is output to the main control circuit board. The main control circuit board receives the distance value transmitted by the laser ranging module and compares the distance value with a distance range preset in a program; when the distance value is smaller than the lower limit of the preset range or higher than the upper limit of the preset range, the light-emitting component 2 can flash to warn to remind the user to adjust the distance to be in a proper range. When the distance value is in a preset range, the main control circuit board can adjust the intensity of the lamplight according to the distance; the smaller the distance, the weaker the light; the larger the distance is, the stronger the lamplight is; the purpose of this control is to make the light intensity reaching the user's face approximately equal at different distances to combat the light decay caused by the increase in distance and to keep the light intensity received by the user always within a suitable range.

The light-emitting panel 21 includes a dimming film, specifically, the light-emitting panel 21 includes a lamp cover 214 positioned in front of the lamp panel 211, and the dimming film is positioned on the lamp cover 214; light emitted by the lamp panel 211 is transmitted through the dimming film; the distance measuring mechanism 22 is used for detecting the distance between the light emitting panel 21 and the user to control the transparency of the dimming film. The light modulation film can adjust the transparency of the light modulation film according to the electric signal output from the main control circuit board; when the electric signal is not received, the dimming film presents frosted glass texture, one part of light cannot pass through, and the other part of light is scattered when passing through; when the electric signal received from the main control circuit board changes from small to large, the transparency of the dimming film can be increased along with the increase of the received electric signal, the transparency of the dimming film is changed according to the distance detected by the distance measuring mechanism 22, when the distance is large, in order to enable the light intensity reaching a user to be enough, the transparency of the dimming film can be improved, when the distance is small, the light stroke is prevented from being too short to cause insufficient scattering, light spots and dark areas are formed on the face of the user, and the transparency of the dimming film can be reduced; when the electric signal received from the main control circuit board is maximum, the dimming film is completely transparent, and the lamp can normally permeate as if the lamp penetrates through transparent glass; in actual use, when the distance is smaller, in order to prevent insufficient scattering caused by too short light stroke, light spots and dark areas are formed on the face of the user, and the transparency of the dimming film is reduced, so that the light emitted by the light-emitting panel 21 is fully scattered, and uniform illumination is formed on the face of the user; when the distance is large, the transparency of the light control film is improved to ensure high transmittance of light emitted from the light emitting panel 21 in order to make the light intensity reaching the user sufficient. The transparency of the dimming film increases with the increase of the input voltage (namely, the electric signal); the smaller the distance detected by the distance measuring mechanism 22, the smaller the voltage output to the dimming film by the main control circuit board, and the lower the transparency of the dimming film. Under low transparency, the texture of the dimming film is close to that of frosted glass, so that a part of light can be blocked, the transmitted light can be fully scattered, and uneven light spots are prevented from being formed on the face of a user when the distance is too short, and the phototherapy effect is prevented from being influenced; on the contrary, when the distance is larger, the voltage output to the dimming film by the main control circuit board is larger, the transparency of the dimming film is higher, the scattering rate of the light is reduced, and the transmittance is improved, so that the condition that the light intensity reaching a user in a long distance is enough and the light decays along with the propagation distance is effectively bridged.

The foregoing is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto, and any person skilled in the art will be able to make insubstantial modifications of the present utility model within the scope of the present utility model disclosed herein by this concept, which falls within the actions of invading the protection scope of the present utility model.
