Description

Technical Field

[0001] This utility model belongs to the field of panel light technology, and specifically relates to a novel panel light structure. Background Technology

[0002] Panel lights are a common type of lighting fixture, characterized by their large and uniform light-emitting surface and slim overall design. They are widely used in various environments. Existing panel lights typically consist of a frame made of spliced ​​profiles, a diffuser plate, a light guide plate, reflective paper, and a light source module housed within the frame, as shown in 202223371890.6. While these lights can meet general usage requirements, the heat generated by the light source module during use is difficult to dissipate effectively in confined spaces. When a significant amount of heat accumulates, it can negatively impact the lifespan of the light source module, thus limiting its applicability. Utility Model Content

[0003] The purpose of this invention is to provide a novel panel light structure with a reasonable structural design and strong heat dissipation performance.

[0004] The technical solution to achieve the purpose of this utility model is a novel panel light structure, including a frame edge formed by splicing, a C-shaped groove provided on the inner side of the frame edge, a base plate, a reflector plate, a light guide plate, and a light-transmitting panel arranged sequentially from top to bottom inside the frame edge, a light source plate provided on the inner wall of the C-shaped groove, and the edges of the base plate, reflector plate, light guide plate, and light-transmitting panel being locked and limited in the C-shaped groove, and a plurality of strip grooves provided on the side wall of the frame edge;

[0005] It is also provided with heat dissipation fins, the ends of which are integrally formed with arc-shaped protrusions to increase the contact area;

[0006] The heat dissipation fins are inserted into the strip grooves, and the arc-shaped protrusions are located in the C-shaped grooves;

[0007] The light source board is attached to the surface of the arc-shaped protrusion through a silicone thermal conductive layer.

[0008] A further preferred embodiment is that the thickness of the heat dissipation fins matches the width of the strip groove;

[0009] The width of the arc-shaped protrusion is greater than the thickness of the heat dissipation fins.

[0010] A further preferred embodiment is that the heat dissipation fins are strip-shaped, arc-shaped, or S-shaped.

[0011] A further preferred embodiment is that a driving power supply connected to the light source board is provided above the base plate.

[0012] A further preferred embodiment is that the frame edge is made of plastic material or aluminum profile.

[0013] A further preferred embodiment is that the light source board is a monochrome or multicolor light source board.

[0014] This utility model has positive effects: The structure of this utility model is reasonable. There is a strip groove on the side wall of the frame, which can be used to install heat dissipation fins. After assembly, the ends of the heat dissipation fins extend out of the frame, which not only improves the heat dissipation performance, but also allows for the replacement of heat dissipation fins of different shapes as needed, which also helps to improve the decorative effect. In addition, the ends of the heat dissipation fins have arc-shaped protrusions, and the light source board is attached to the arc-shaped protrusions, which can increase the heat conduction contact area and improve the effectiveness of heat conduction and heat dissipation, making it highly applicable.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example

[0022] See Figures 1 to 3As shown, a novel panel light structure includes a frame 1 formed by splicing. A C-shaped groove 2 is provided on the inner side of the frame. From top to bottom, a base plate 3, a reflector 4, a light guide plate 5, and a light-transmitting panel 6 are sequentially arranged inside the frame. A light source plate 7 is provided on the inner wall of the C-shaped groove. The edges of the base plate, reflector, light guide plate, and light-transmitting panel are engaged and limited within the C-shaped groove. This structure is a conventional structure in the prior art. The light source plate is a single-color or multi-color light source plate. The frame is made of plastic or aluminum profile.

[0023] In this embodiment, several strip grooves 8 are provided on the sidewall of the frame edge; these strip grooves can be vertically or horizontally arranged, and heat dissipation fins 9 are also provided. The ends of the heat dissipation fins are integrally formed with arc-shaped protrusions 10 to increase the contact area. During assembly, the heat dissipation fins are inserted into the strip grooves, and the arc-shaped protrusions are located in the C-shaped grooves. The light source plate is attached to the surface of the arc-shaped protrusions through a silicone thermal conductive layer 11. The heat from the light source plate is guided to the arc-shaped protrusions through the silicone thermal conductive layer and dissipated outwards by the heat dissipation fins. Through the above structure, not only is it convenient to disassemble, install, and replace the heat dissipation fins for maintenance, but also different shaped heat dissipation fins can be installed to enhance the decorative effect of the panel light.

[0024] In this embodiment, the thickness of the heat dissipation fins matches the width of the strip groove; the width of the arc-shaped protrusion is greater than the thickness of the heat dissipation fins. This structure ensures that the heat dissipation fins are not easily loosened, shaken, or shifted after assembly. Furthermore, the heat dissipation fins are strip-shaped, arc-shaped, or S-shaped. A driving power supply 11 connected to the light source board is disposed above the base plate. This driving power supply uses a conventional structure from the prior art, simply applied in a basic manner.

[0025] This utility model has positive effects: The structure of this utility model is reasonable. There is a strip groove on the side wall of the frame, which can be used to install heat dissipation fins. After assembly, the ends of the heat dissipation fins extend out of the frame, which not only improves the heat dissipation performance, but also allows for the replacement of heat dissipation fins of different shapes as needed, which also helps to improve the decorative effect. In addition, the ends of the heat dissipation fins have arc-shaped protrusions, and the light source board is attached to the arc-shaped protrusions, which can increase the heat conduction contact area and improve the effectiveness of heat conduction and heat dissipation, making it highly applicable.

[0026] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0027] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
