By arranging a plurality of light-emitting components 2 which can generate light of differentiated wavelengths on the PCB board 1, light of multiple wavelengths can be irradiated in the same direction and overlapped to form a phototherapy area, which ensures that the phototherapy area is completely covered by light of each wavelength, so that the phototherapy area has unified diversified functions, and can also optimize the equipment, reduce the equipment cost, and improve the user experience.

The upper shell 5 is formed by extrusion, which is convenient for cutting a suitable length according to needs and blocking the ports at both ends of the accommodating cavity 13 by the end caps 11, which not only effectively improves the structural strength of the upper shell 5, but also facilitates installation and operation. An axial hole is provided on the vertical section of the upper shell 5, and the axis of the axial hole is arranged along the length direction of the upper shell 5, so that the end caps 11 are conveniently fixed by fasteners.

[0026] In actual operation, the light-emitting assembly includes a diffuser plate 3 arranged below the light-emitting element 2, and the light-emitting element 2 is arranged on the bottom surface of the PCB board 1. The diffuser plate 3 is provided with lenses 4 vertically aligned with the light-emitting element 2 one by one, and the light generated by the light-emitting element 2 is diffused through the lenses 4 and superimposed to form the phototherapy area. The light-emitting elements 2 are arranged in a matrix on the PCB board 1, and the lenses 4 on the diffuser plate 3 and the diffuser ports 15 on the lower cover 6 are arranged in a matrix, so that the light-emitting element 2, the lenses 4 and the diffuser ports 15 are vertically aligned to ensure that the light generated by the light-emitting element 2 can pass through the lens 4 downward and then irradiate outward through the diffuser ports 15. The light increases the irradiation area through the lens 4, so that multiple beams of light with different wavelengths are superimposed to form a phototherapy area, and a phototherapy operation is performed on a specific area of ​​the user and the corresponding function is obtained. In a preferred embodiment, the light-emitting element 2 is four and can generate four different wavelengths of light. The light-emitting elements 2 within the range of 2*2 are set as a group and four light-emitting elements 2 that can generate light of different wavelengths are configured to increase the area of ​​the phototherapy area formed by the superposition of the four light rays.

The cross-sectional profile of the accommodating cavity 13 is an isosceles trapezoid with a small top and a large bottom. The cross-sectional profile of the bracket 7 matches the top profile of the accommodating cavity 13.
