Abstract
Description
Technical Field
[0001] This utility model relates to the field of side-emitting cabinet lights, and more specifically, to a side-emitting cabinet light. Background Technology
[0002] Currently, most side-emitting cabinet lights on the market suffer from fixed light sources and reflective structures. The internal LED light source arrangement and reflector angles are fixed at the factory, making it impossible to flexibly adjust them according to actual lighting needs during use. This rigid design prevents users from adjusting the light projection angle for items of different heights, cabinet spaces of different depths, or special display requirements. When it's necessary to focus on illuminating items deep within the cabinet or change the light coverage, the only solution is to reinstall the light fixture, reducing usability and limiting precise control of the lighting effect. Especially in variable scenarios such as kitchen countertops and display cabinets, fixed illumination angles can easily create blind spots or glare, severely impacting the product's adaptability to different scenarios and the user experience. Utility Model Content
[0003] (a) Technical problems to be solved
[0004] To address the problems existing in the prior art, this utility model provides a side-emitting cabinet light to solve the technical problem mentioned in the background art that the illumination angle of the side-emitting cabinet light can be flexibly adjusted.
[0005] (II) Technical Solution
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A side-emitting cabinet light includes a base shell, with a light strip inclinedly arranged at the bottom inner end of the base shell. A light guide plate is arranged above the light strip, and mounting shafts are arranged at both ends of the light guide plate. Protective side plates are arranged on both sides of the base shell, and mounting slots are formed on the protective side plates. The mounting shafts are rotatably arranged in the mounting slots, and damping pads are arranged between them and the inner walls of the mounting slots. One side of the mounting shaft extends to the outer side of the protective side plate and is provided with an adjustment knob. The surface of the light guide plate is provided with a light-guiding shape. A heat-conducting sheet is arranged at the bottom inner end of the base shell, and a heat dissipation fin is arranged at the bottom end of the heat-conducting sheet. The heat dissipation fin extends to the outer end of the base shell, and a lampshade is arranged at the front end of the base shell.
[0008] The present invention is further configured such that an installation port is provided at the front end of the bottom shell, and the lampshade is disposed at the installation port. By placing the lampshade at the installation port, it can cooperate with the light strip and the light guide plate to transmit the light source emitted by the light strip outward to achieve illumination.
[0009] The present invention is further configured such that a locking groove is provided at the mounting opening, and the lampshade is sealed and locked in the locking groove, thereby achieving stable installation of the lampshade on the bottom shell through the locking groove.
[0010] The present invention is further configured such that mounting seats are symmetrically arranged inside the bottom shell, and mounting grooves are provided on the mounting seats. The light strip is arranged in the mounting grooves, and the light strip is quickly and conveniently installed in the bottom shell through the cooperation of the mounting seats and the mounting grooves.
[0011] The present invention is further configured such that the interior of the bottom shell is provided with a limiting protrusion, and the interior of the protective side plate is provided with a limiting snap tooth. The limiting snap tooth and the limiting protrusion are mutually limiting and engaging, and the protective side plate can be quickly installed and removed from the bottom shell through the cooperation of the limiting protrusion and the limiting snap tooth.
[0012] The present invention is further configured such that the inner end of the mounting shaft connected to one side of the adjustment knob is provided with a connecting section, and the light guide plate is provided with a connecting groove. The connecting section and the connecting groove are engaged with each other and are both non-circular. During installation, when the corresponding protective side plate is engaged and fixed on the bottom shell, the connecting end on the inner side of the corresponding mounting shaft engages into the corresponding connecting groove. In this way, while realizing the rotation adjustment of the light guide plate, it is convenient to install and remove the protective side plate. Power interface, control button and other related structures can be installed on the protective side plate. This is the prior art and has little to do with the structural improvement of the present invention. The present invention will not elaborate on this.
[0013] The present invention is further configured such that the light guide shape is a fine ridge or a diffusion particle, which reduces the light spot and improves uniformity.
[0014] The present invention is further configured such that a diffusion film is laminated on the surface of the light guide plate, which can further soften the light and avoid "graininess".
[0015] (III) Beneficial Effects
[0016] Compared with the prior art, this utility model provides a side-emitting cabinet light, which has the following beneficial effects:
[0017] 1. This utility model has an inclined light strip installed at the bottom of the inner shell, and a light guide plate installed above the light strip. The two ends of the light guide plate are rotatably mounted between two sets of protective side plates through the cooperation of mounting shafts, mounting slots, and damping pads. An adjustment knob is installed in conjunction with the mounting shaft. In use, rotating the adjustment knob can control the mounting shaft to drive the light guide plate to rotate, so that the light source emitted by the light strip can directly illuminate the light guide plate. By rotating the angle of the light guide plate, the angle of the light source reflected by the light guide plate can be adjusted, thereby realizing flexible adjustment of the lighting angle.
[0018] 2. This invention features a light-guiding shape on the surface of a light guide plate, which can be a fine ridge or diffuser particles. These ridges or diffuser particles effectively control the light propagation path: the ridges guide side-incident light to the front through refraction / reflection, improving light uniformity; the diffuser particles eliminate local bright spots through scattering, softening the light. Together, they reduce glare, achieving a highly uniform surface light source effect, while also improving luminous efficiency (reducing light leakage), and the beam angle can be adjusted through the texture design.
[0019] 3. This utility model has a heat-conducting plate at the bottom of the inner shell, and a heat dissipation fin at the bottom of the heat-conducting plate, which extends to the outer end of the shell. The heat-conducting plate and the heat dissipation fin are preferably made of materials with good thermal conductivity and heat dissipation, such as aluminum-based, copper, thermally conductive ceramic, thermally conductive silicone, etc., which can be freely selected according to insulation requirements. In this way, after the light strip is installed inside the shell, the bottom end of the light strip can be in contact with the heat-conducting plate, so that the heat generated by the light strip can be quickly transferred to the outside through the heat-conducting plate and the heat dissipation fin, thereby improving the heat dissipation effect of the light strip.

[0039] This invention features a light guide shape 9 on the surface of a light guide plate 3. The light guide shape 9 is either a fine ridge or a diffusion particle.
