Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically a light guide plate type cabinet light. Background Technology

[0002] Cabinet lights, also known as cabinet lights, are primarily used for localized lighting and decoration within cabinets. Originating in the 1980s, cabinet lights have evolved over the years from simple quartz lamps to dedicated lighting fixtures for each section of the cabinet. They have also progressed from halogen lamps to fluorescent lamps, and finally to LED lights, meeting the demands for safety, energy efficiency, and environmental friendliness.

[0003] Traditional cabinet lights typically use high-density LED strips that need to be mounted on a U-shaped profile at least 10mm high, with a PC milky white cover on the surface. This process requires sufficient space to fit cabinets of this height, and the uniformity of light output will vary depending on the color of the light emitted by different LED beads.

[0004] Based on this, ordinary cabinet lights currently on the market cannot be made flat to suit small spaces, and there are also problems with inconsistent light colors caused by high-density LEDs, resulting in differences in the color of the light emitted by the entire lamp, which affects the user experience. Therefore, a light guide plate type cabinet light is proposed to solve the problems mentioned above. Utility Model Content

It solves the problems of ordinary cabinet lights on the market that cannot be made flat to suit small spaces, and that high-density LEDs may have inconsistent light colors, resulting in color differences in the overall light output of the lamp.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a light guide plate type cabinet light, comprising an aluminum profile, wherein a light assembly is provided on the inner side of the aluminum profile; The lighting assembly includes an LED light source board, a white light-diffusing film is provided on the upper side of the LED light source board, a light guide plate is provided on the upper side of the white light-diffusing film, the LED light source board, the white light-diffusing film and the light guide plate are integrally embedded in the inner side of the aluminum profile, and a first plastic plug and a second plastic plug are respectively inserted into both ends of the aluminum profile, and a power supply wire is provided on the outer side of the first plastic plug.

[0007] Furthermore, the light guide plate is an acrylic light guide plate.

[0008] Furthermore, the bottom of the aluminum profile is provided with two mounting clips.

[0009] Furthermore, the white light-diffusing film is bonded to the bottom of the light guide plate.

[0010] Furthermore, the power supply wire is connected to the LED light source board.

[0011] Furthermore, a wire hole is provided on the inner side of the first plastic plug, and the power supply wire passes through the inner side of the wire hole.

[0012] Furthermore, the inner side of the aluminum profile is integrally adapted to the LED light source board, the white light-diffusing film, and the light guide plate.

[0013] Compared with the prior art, this utility model provides a light guide plate type cabinet light, which has the following beneficial effects: This light guide plate type cabinet light uses an LED light source board, a white light-diffusing film, and a light guide plate in combination to replace the traditional front lighting technology. The LEDs at both ends of the LED light source board illuminate the cross-sections at both ends of the light guide plate. The light beam enters the interior of the light guide plate through the cross-section and then emits light evenly from the front of the light guide plate. Only two LEDs are needed to achieve uniform light output from the light guide plate and ensure uniform light output height. The combination of LED light source board, white light-diffusing film, light guide plate, and aluminum profile results in a compact structure, small footprint, and wide applicability, making it effective for use in various spaces.
