[0028] Reference Figure 1-3The light strip comprises a shell 100, a diffuser 200 and a light board 300, wherein lamp beads 310 are provided on the light board 300, and the shell 100 and the diffuser 200 are both long strips. The shell 100 is a U-shaped shell structure surrounded by an upper wall 110, a lower wall 120 and a rear wall 130. The diffuser 200 is located at the front side of the shell 100 and is connected between the upper wall 110 and the lower wall 120. The shell 100 and the diffuser 200 together surround an elongated inner cavity, and the lamp board 300 is installed in the inner cavity along the length direction of the inner cavity, the lamp board 300 is arranged between the upper wall 110 and the lower wall 120, and the lamp beads 310 face the diffuser 200. A reflector 500 is provided on the inner side of the upper wall 110 and the inner side of the lower wall 120, and the reflector 500 is located between the lamp board 300 and the diffuser 200. The shell 100, the diffuser 200 and the reflector 500 are an integrated structure. Specifically, the housing 100 , the diffuser 200 and the reflector 500 are manufactured by an integrated three-color extrusion process, and different mirror cabinets are cut to different lengths according to actual size requirements.

[0029] The utility model comprises a diffuser 200, upper and lower reflectors 500 and a lamp panel 300 to form an optical cavity 410. Light is emitted from the lamp beads 310. After the light reaches the diffuser 200, part of the light is scattered through the diffuser 200, and part of the light is reflected back into the optical cavity 410. The light is reflected and mixed back and forth between the diffuser 200, the lamp panel 300 and the upper and lower reflectors 500. Finally, most of the light is scattered out in the diffuser 200. Therefore, before passing through the diffuser 200, the light has been fully mixed in the optical cavity 410, achieving a uniform and efficient light output effect.

[0030] In some embodiments of the present invention, the reflector 500 completely covers the housing 100 located between the light panel 300 and the diffuser 200 .

[0031] In some embodiments of the present invention, both the upper wall 110 and the lower wall 120 are provided with a slot 600 , which is arranged along the length direction of the housing 100 , and the light board 300 is embedded in the slot 600 . The slot 600 is used to fix the light board 300 .

[0032] Some embodiments of the present invention also include two end caps 700, one on each side of the housing 100, to seal the inner cavity. The end caps 700 are internally bonded to the lamp body (using glue, snaps, ultrasonic welding, or other methods), resulting in a clean, elegant design without screw holes and a strong sense of integrity for the light strip.

[0033] In some embodiments of the present invention, a mounting bracket 710 is provided on the rear side of the end cap 700. The mounting bracket 710 is arranged in a front-to-back direction, and the end cap 700 and the mounting bracket 710 are an integral structure. The mounting bracket 710 is long and is used to fix the light bar to the cabinet top. The mounting bracket 710 can be fastened to the cabinet top using screws.

[0034] In some embodiments of the present invention, the lamp beads 310 are located above the light board 300, close to the upper wall 110. These LED lamp beads 310 are offset on the light board 300, leaving more space below for arranging the power supply, controller, and wiring of the light board 300, thereby increasing the usable space of the light board 300. Furthermore, the upward placement of the lamp beads 310 allows more light to be reflected downward from the reflector 500 on the upper wall 110, increasing downlighting.

[0035] In some embodiments of the present invention, a space is left between the light panel 300 and the rear wall 130 to form a housing cavity 420. This cavity 420 houses the light strip's power supply, controller, and wiring for the light panel 300. The light panel 300 divides its interior into an optical cavity 410 and a housing cavity 420. The optical cavity 410 is located at the front of the light panel 300, while the housing cavity 420 is located at the rear. By integrating the power supply and controller into the light strip through the housing cavity 420, the integrated design optimizes the fixture's spatial layout and significantly improves assembly speed and quality.

[0036] In some embodiments of the present invention, the width of the upper wall 110 is greater than that of the lower wall 120, and the diffuser cover 200 is curved and tilted downward. When the light bar is placed on the cabinet top, the light passes through the downward-tilted diffuser cover 200 and is evenly distributed in a direction approximately 0.5 meters in front of the mirror. The light is evenly distributed in any angle between 0° and 90° directly in front of the mirror cabinet.

[0037] In some embodiments of the present invention, the housing 100, diffuser 200, and reflector 500 are made of one of PC, PMMA, or PP. The housing 100 is dark, the diffuser 200 is translucent, and the reflector 500 is white. The housing 100 can be dark gray to absorb some of the light that leaks while matching the dark color of the cabinet.

[0038] A mirror cabinet includes the above-mentioned light strip. The entire light strip is placed on the cabinet top, the light strip adopts rear-exit wiring, and the light strip is tightly matched with the cabinet body, which has strong integrity and integrated functions, and greatly improves assembly speed and quality.

[0039] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
