Description

Technical Field

[0001] This utility model belongs to the field of ceiling light technology, specifically designing an LED ceiling light with a heat dissipation structure. Background Technology

[0002] Ceiling lights are a common type of lighting fixture, consisting of a ceiling bracket, lamp holder, light source board, and lampshade. During assembly, the light source board is fixed to the lamp holder, and the lamp holder is snapped together with the ceiling bracket. While this can meet general usage needs, the lamp holder's limited space for heat dissipation due to its attachment to the ceiling bracket during installation results in ineffective heat dissipation. Over time, this can affect the lifespan of the light source board, thus limiting its applicability and practicality. Utility Model Content

[0003] The purpose of this invention is to provide an LED ceiling light with a reasonable structural design that is conducive to improving heat dissipation performance.

[0004] The technical solution to achieve the purpose of this utility model is an LED ceiling light with a heat dissipation structure, including a ceiling bracket fixed on the ceiling, a lamp body set on the ceiling bracket, the lamp body including a lamp holder, a light source plate and a lamp cover fixed on the lamp holder, a protruding ring fixed on the top surface of the lamp holder, an L-shaped slot provided on the side wall of the protruding ring, and the ceiling bracket being located inside the protruding ring and locked into the L-shaped slot for positioning;

[0005] The top and bottom surfaces of the lamp holder are integrally formed with an annular protrusion, and the light source plate is fixed to the bottom surface of the annular protrusion.

[0006] A cooling fan is fixed in the middle of the inner cavity of the annular protrusion, and a heat conduction hole is provided on the top wall of the lamp holder, the heat conduction hole being located inside the annular protrusion.

[0007] The lower part of the side wall of the lamp holder and the lower part of the annular protrusion are both provided with air inlets;

[0008] When the cooling fan is activated, the air inlet, the annular protrusion, and the heat conduction holes form a heat dissipation channel.

[0009] A further preferred embodiment is that a rubber pad is provided between the edge of the light source plate and the inner wall of the lamp holder;

[0010] The edge of the light source board is seamlessly connected to the lamp holder via a rubber abutment.

[0011] A further preferred embodiment is that: an annular protective cylinder is provided on the outer surface of the lamp holder, and a guide wheel is provided on the top of the side wall of the lamp holder;

[0012] A Z-shaped pry bar is rotatably mounted on the side wall of the annular protrusion via a pin. One end of the Z-shaped pry bar extends into the inner cavity of the annular protrusion, and the outer end of the Z-shaped pry bar is connected to the top of the annular protective cylinder via a pull wire, with the pull wire positioned on a guide wheel.

[0013] The cooling fan blows air, and the annular protrusion causes the Z-shaped fins to rotate around the pivot pin. The pull wire moves the annular protective cylinder upward away from the air inlet, thus opening the air inlet.

[0014] A further preferred embodiment is that the annular protective cylinder is a plastic cylinder with a thickness of 0.1-0.5 mm.

[0015] A further preferred embodiment is that the height of the annular protective cylinder is 1 / 3 to 1 / 2 of the height of the lamp holder;

[0017] A further preferred embodiment is that a return spring is provided between the Z-shaped paddle and the outer wall of the annular protrusion.

[0018] This utility model has positive effects: The structure of this utility model is reasonably designed. Through the air inlet, the annular protrusion, the cooling fan and the heat conduction hole, a heat dissipation channel can be formed, which can quickly and effectively dissipate the heat in the lamp holder to the outside, improve the heat dissipation performance, and will not affect the ease of disassembly and assembly of the lamp holder and the ceiling base, making it highly practical.

[0019] Furthermore, it is equipped with a ring-shaped protective cylinder in conjunction with a Z-shaped fin and a pull wire. When the cooling fan is started, the airflow will drive the Z-shaped fin to rotate. Since the length of the pull wire is fixed, the ring-shaped protective cylinder can be pulled upward by the pull wire when the Z-shaped fin rotates. Normally, it can cover the air inlet hole, which helps to improve the overall appearance. When blowing air, the air inlet hole will be exposed to ensure the effectiveness of heat dissipation and air intake, improve the stability and reliability of heat dissipation, and is highly practical.

Detailed Implementation

[0025] 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.

[0026] Example

[0027] See Figures 1 to 3 As shown, an LED ceiling light with a heat dissipation structure includes a ceiling bracket 1 fixed to the ceiling and a light fixture body 2 mounted on the ceiling bracket. The light fixture body includes a lamp holder 21, a light source plate 22 fixed to the lamp holder, and a lampshade 23. A protruding ring 3 is fixed on the top surface of the lamp holder, and an L-shaped groove 4 is provided on the side wall of the protruding ring. The ceiling bracket is located inside the protruding ring and is positioned by being engaged in the L-shaped groove. In this embodiment, the above structures are all conventional structures in the prior art, so they are not described in detail, but are simply applied.

[0028] In practical applications, the top and bottom surfaces of the lamp holder are integrally formed with an annular protrusion 5, and the light source plate is fixed to the bottom surface of the annular protrusion. Through the above structure, not only can the installation convenience of the light source plate be improved, but also a certain gap can be made between the light source plate and the top surface of the lamp holder.

[0029] Furthermore, in practical applications, a cooling fan 6 is fixed in the center of the annular protrusion, and a heat-conducting hole 7 is provided on the top wall of the lamp holder, located within the annular protrusion. Air inlets 8 are provided on the lower part of the side wall of the lamp holder and the lower part of the annular protrusion. During use, the cooling fan is activated, forming a heat dissipation channel between the air inlets, the annular protrusion, and the heat-conducting holes. In use, the air inlets and heat-conducting holes are separated by the top wall of the lamp holder, and the air inlets are located on the lower part of the side wall of the lamp holder, which reduces the interference between air intake and exhaust.

[0030] In practical applications, a rubber pad 9 is provided between the edge of the light source plate and the inner wall of the lamp holder; the edge of the light source plate and the lamp holder are seamlessly connected by the rubber pad. This structure prevents dust and other contaminants from entering between the light source plate and the lamp cover, ensuring the stability and effectiveness of the lamp's illumination.

[0031] In practical applications, the outer surface of the lamp holder is provided with an annular protective cylinder 10, and the top of the side wall of the lamp holder is provided with a guide wheel 11. A Z-shaped pry bar 13 is rotatably mounted on the side wall of the annular protrusion via a pin 12. One end of the Z-shaped pry bar extends into the inner cavity of the annular protrusion, and the outer end of the Z-shaped pry bar is connected to the top of the annular protective cylinder via a pull wire 15, which is positioned on the guide wheel. During use, the cooling fan blows air, and the airflow from the annular protrusion drives the Z-shaped pry bar to rotate around the pin. The pull wire then moves the annular protective cylinder upwards away from the air inlet, opening the air inlet. This structure allows the air inlet to be covered under normal conditions, improving the overall aesthetics. During operation, the air inlet is exposed, ensuring effective heat dissipation and improving the stability and reliability of heat dissipation.

[0032] Furthermore, in practical applications, to reduce the weight of the annular protective cylinder, it is made of plastic with a thickness of 0.1-0.5mm. This allows for the smooth and effective lifting and lowering of the annular protective cylinder via a pull cable.

[0033] In practical applications, the height of the annular protective cylinder is 1 / 3 to 1 / 2 of the lamp holder height; the inner surface of the annular protective cylinder is attached to the outer surface of the lamp holder. This structure improves the effectiveness of the annular protective cylinder's lifting and lowering. In this embodiment, a decorative surface can also be provided on the outer wall of the annular protective cylinder.

[0034] In practical applications, a return spring 14 is provided between the Z-shaped rocker and the outer wall of the annular protrusion. The spring force of the return spring is small, which can achieve the return without affecting the rotation of the Z-shaped rocker, thus ensuring the effectiveness of the entire operation.

[0035] This utility model has positive effects: The structure of this utility model is reasonably designed. Through the air inlet, the annular protrusion, the cooling fan and the heat conduction hole, a heat dissipation channel can be formed, which can quickly and effectively dissipate the heat in the lamp holder to the outside, improve the heat dissipation performance, and will not affect the ease of disassembly and assembly of the lamp holder and the ceiling base, making it highly practical.

[0036] Furthermore, it is equipped with a ring-shaped protective cylinder in conjunction with a Z-shaped fin and a pull wire. When the cooling fan is started, the airflow will drive the Z-shaped fin to rotate. Since the length of the pull wire is fixed, the ring-shaped protective cylinder can be pulled upward by the pull wire when the Z-shaped fin rotates. Normally, it can cover the air inlet hole, which helps to improve the overall appearance. When blowing air, the air inlet hole will be exposed to ensure the effectiveness of heat dissipation and air intake, improve the stability and reliability of heat dissipation, and is highly practical.

[0037] 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.

[0038] 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.
