Referring to Figures 1-3, a dual-band light-emitting device includes:

The housing 100 has a cavity therein:

A lamp tube 200, wherein the lamp tube 200 is fixed in the housing 100, and a window for light to pass through is provided on the surface of the housing 100;

A reflective cup 300, wherein the opening of the reflective cup 300 faces the window of the housing 100 and covers the lamp cup;

The filter assembly 400 is fixed at the window of the housing 100;

There are two or more filters stacked in the filter assembly 400 , and the two or more filters in the filter assembly 400 cooperate with each other to filter the light of the lamp tube 200 at the same time.

The lamp tube 200 is fixed in the housing 100, and a window is provided on the surface of the housing 100 to allow light to pass through. The opening of the reflective cup 300 faces the window of the housing 100 and covers the lamp tube 200. The function of the reflective cup 300 is to reflect and focus the light emitted by the lamp tube 200 to enhance the lighting effect. The filter component 400 is fixed at the window of the housing 100, and two or more filters are superimposed in the filter component 400. The function of the filter component 400 is to filter the light of the lamp tube 200 and only pass light of a specific band. These filters can select different bands as needed to achieve multi-band phototherapy. When the device is working, the light emitted by the lamp tube 200 is filtered by the filter component 400, and only light of a specific band passes through. Then, these passing light rays are reflected and focused by the reflective cup 300 and projected onto the skin surface to achieve beauty treatment.

By stacking two or more filters in the filter assembly 400, multi-band phototherapy can be achieved. Users can choose different bands according to their needs to meet different beauty goals. The filter assembly 400 filters the light of the lamp tube 200 and only transmits light of a specific band. This ensures that only the required light is irradiated to the skin surface, improving the phototherapy effect.

In this embodiment, the two or more filters in the filter assembly 400 cooperate with each other to filter the light of the lamp tube 200. The presence of the heat insulation baffle 430 can effectively isolate the heat conduction between the filter and the lamp tube 200, preventing the filter from being damaged due to overheating. This helps to improve the stability and life of the device.

The heat insulation partition 430 is made of Teflon. Teflon is a material with excellent heat resistance and chemical inertness, and has good heat insulation performance. It can effectively isolate the heat conduction between the filter and the lamp 200, and provide better heat management for the device.

In this embodiment, the filter assembly 400 includes a first filter 410 and a second filter 420. The first filter 410 is a bandpass filter close to the light, and the second filter 420 is a bandstop filter. When the device is working, the light emitted by the lamp tube 200 first passes through the filter assembly 400. The first filter 410 is a bandpass filter, which allows a larger band of light to pass through. It has specific optical properties and can selectively transmit a certain range of spectral bands. The second filter 420 is a bandstop filter, which blocks the band of light. The light of the larger band passed by the first filter 410 is split into two different bands of light after passing through the second filter 420. The second filter 420 achieves light segmentation by blocking the band of part of the light.

This technical solution can achieve dual-band light output through the cooperation of the first filter 410 and the second filter 420. The combination of the first filter 410 and the second filter 420 achieves the band division of light. By blocking part of the light band, the device can achieve more accurate phototherapy and provide targeted treatment for different skin problems. Due to the cooperation of the first filter 410 and the second filter 420, the device has flexibility and adaptability. Users can choose the appropriate filter combination according to their needs to meet different phototherapy needs and treatment goals.

In this embodiment, the interval of the wavelength band passed by the first filter 410 includes the interval of the wavelength band blocked by the second filter 420. Through accurate wavelength selection, the device can provide more accurate phototherapy effects. Light of different wavelength bands can be used for targeted treatment of different skin problems, thereby improving the accuracy and effect of treatment.

Examples of the first filter and the second filter working together to achieve dual-band include but are not limited to:

The passing band of the first filter is 500-1800nm, the blocking band of the second filter is 650-900nm, and finally the dual-band light of 500-650nm and 900-1800nm is output. For example, it can be used for skin whitening and skin regeneration treatment.

The passing band of the first filter is 500-1200nm, the blocking band of the second filter is 680-800nm, and finally the dual-band light of 500-680nm and 800-1200nm is output. For example, it can be used for the treatment of acne and telangiectasia.

The first filter has a passband interval of 500-1200nm, the second filter has a blocking band interval of 670-870nm, and finally outputs dual-band light of 500-670nm and 870-1200nm. For example, it can be used for the treatment of reducing pigmentation and skin tightening.

The passing band of the first filter is 530-1200nm, the blocking band of the second filter is 650-900nm, and finally the dual-band light of 530-650nm and 900-1200nm is output. For example, it can be used for the treatment of freckle removal and skin anti-aging.

The passing band of the first filter is 400-1200nm, the blocking band of the second filter is 600-800nm, and finally the dual-band light of 400-600nm and 800-1200nm is output. For example, it can be used for acne treatment and hair removal treatment.

The device can output two bands of light at the same time. Such dual-band light therapy function provides more choices to meet different beauty needs and skin problems.

In this embodiment, the housing 100 is provided with an air inlet 110 and an air outlet 120, and the air inlet 110 and the air outlet 120 are connected to the cavity of the housing 100 to form a heat dissipation duct. The design of the air inlet 110, the air outlet 120 and the heat dissipation duct effectively promotes the dissipation of heat inside the device. This can reduce the operating temperature of the device and improve the stability and reliability of the equipment. The heat dissipation duct provides a channel for the flow of hot gas, so that the hot gas can quickly flow out of the device to avoid heat accumulation inside the device. This can improve the heat dissipation efficiency and maintain the normal operating temperature of the device.

In this implementation case, two ends of the reflective cup 300 are connected, and the reflective cup 300 is placed along the heat dissipation channel.

The reflective cup 300 is a cup-shaped structure, with both ends being conductive, that is, open, to form a channel. Through the conductive structure of the reflective cup 300, the hot gas can flow along the channel direction and be discharged from the other end. This can improve the flow efficiency of the hot gas and promote the rapid dissipation of heat. The conductive structure of the reflective cup 300 enables the hot gas to flow evenly in the channel. This helps to evenly distribute the heat inside the device, avoid the generation of hot spots, and improve the heat dissipation effect. By placing the conductive structure of the reflective cup 300 along the direction of the heat dissipation channel, the resistance of the hot gas in the channel can be reduced, and the possibility of hot gas accumulation and blockage can be reduced. This helps to improve the stability and reliability of the device.

In this embodiment, a heat sink 500 is also included, and the heat sink 500 is located in the heat dissipation duct and is in close contact with the back of the reflective cup 300. The close contact between the heat sink 500 and the reflective cup 300 helps to evenly conduct heat, thereby avoiding the generation of hot spots, improving the uniform distribution of heat inside the device, and further improving the uniformity of heat dissipation.

In this embodiment, a heat sink 500 is also included, and a heat sink fin is provided on the surface of the heat sink 500. The presence of the heat sink fin increases the surface area of the heat sink 500 and improves the efficiency of heat dissipation. In this way, heat can be dissipated more quickly and the temperature of the device can be reduced.

In this embodiment, both ends of the lamp tube 200 are provided with a current transfer plate 600, and the current transfer plate 600 penetrates the shell 100 and is connected to an external power supply. Through the design of the current transfer plate 600, the connection between the lamp tube 200 and the external power supply is simpler. No additional wires or sockets are required, and it is only necessary to connect to the external power supply through the current transfer plate 600. A sealing structure is provided at the connection point between the current transfer plate 600 and the shell 100 to ensure that the connection point has good insulation and sealing performance. In this way, the power supply of the lamp tube 200 can be guaranteed to be safe and reliable, and current leakage and other electrical problems can be avoided.
