Description

Technical Field

[0001] This utility model belongs to the field of lighting technology, and specifically relates to lighting fixtures with heat dissipation function. Background Technology

[0002] With the rapid development of lighting technology, lamps are being used more and more widely, but the resulting heat dissipation problem has gradually become a focus of industry attention. Traditional lamp designs, while pursuing lighting effects, often neglect the effective heat dissipation of key heat-generating components such as LED strips. Under prolonged high-load operation, these components easily accumulate a large amount of heat, leading to excessively high internal temperatures and damage to the lamp. This overheating phenomenon severely shortens the lifespan of the lamp. Utility Model Content

[0003] The purpose of this invention is to overcome the problem that existing lamps tend to accumulate a lot of heat under long-term high-load operation, leading to excessive internal temperature and damage, and to provide a lamp with heat dissipation function.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A luminaire with heat dissipation function includes a luminaire body, a decorative structure, a light strip, and a light source diffuser plate. The luminaire body has a lighting cavity with an opening at the bottom, and a support edge is provided on the inner circumference of the lower end of the lighting cavity. The decorative structure includes a heat dissipation ring and a light strip assembly ring located on the outer upper side of the heat dissipation ring, with a step formed between the light strip assembly ring and the top surface of the heat dissipation ring. The light strip is arranged circumferentially on the inner circumference of the light strip assembly ring. The light source diffuser plate is installed on the step and is installed inside the lighting cavity when the bottom of the decorative structure rests on the support edge.

[0006] Compared with existing technologies, this utility model's heat dissipation lamp utilizes a decorative structure on the outer periphery of the bottom of the light source diffuser plate. This decorative structure includes a heat dissipation ring and a light strip assembly ring connected to the outer upper end of the heat dissipation ring. The light strip is installed inside the light strip assembly ring, projecting light onto the light source diffuser plate. This allows the heat generated by the light strip during operation to be transferred to the heat dissipation ring for cooling, effectively preventing the lamp's internal temperature from becoming too high and thus avoiding the risk of damage due to overheating. Furthermore, the stepped portion formed between the light strip assembly ring and the top surface of the heat dissipation ring not only facilitates the installation of the light source diffuser plate but also further enhances the lamp's heat dissipation performance, improving the stability and reliability of the lighting system.

[0007] Furthermore, the heat dissipation ring and the light strip assembly ring are an integral structure, and the decorative structure is made of metal material; with this arrangement, the decorative structure made of metal material has better heat conduction effect.

[0008] Furthermore, the inner circumference of the heat dissipation ring has multiple inwardly protruding heat dissipation portions; the heat dissipation portions are rectangular, circular, or irregular in shape; by setting it in this way, the heat dissipation ring has a larger heat dissipation area, better heat dissipation effect, and can also improve the decorative effect of the decorative structure.

[0009] Furthermore, the heat dissipation part extends downward and its back abuts against the outer end of the support edge; with this arrangement, the heat dissipation part extends downward and covers the outer end of the support edge, making the lamp more aesthetically pleasing.

[0010] Furthermore, the lamp body includes an upper shell assembly and a decorative ring. The decorative ring is installed on the outer periphery of the bottom of the upper shell assembly, and the lighting cavity is formed between the decorative ring and the upper shell assembly. The support edge is located on the inner periphery of the decorative ring. With this arrangement, the lamp body structure is simple in design and convenient for product manufacturing.

[0011] Furthermore, it also includes a clamping plate located on top of the light source diffuser plate. The clamping plate includes a clamping part, a clearance part, and a connecting edge respectively arranged along the outer direction. The bottom of the clearance part is provided with a clearance groove that cooperates with the lamp strip assembly ring. The connecting edge is connected to the top of the decorative ring by screws so that the clamping part presses the light source diffuser plate firmly onto the step part. With this arrangement, the installation of the light source diffuser plate is stable, effectively improving the reliability of the product.

[0012] Furthermore, the bottom surface of the decorative ring is arranged to be inclined upward along the outer direction to form a guide decorative surface; with this arrangement, the decorative ring has an upwardly inclined arrangement to form a guide decorative surface, making the lamp fixture three-dimensional and more aesthetically pleasing.

[0013] Furthermore, it also includes light-emitting components and light-transmitting ring covers. Several light-emitting components are provided and are respectively located in the lamp grooves on the outer periphery of the upper shell component. The light-transmitting ring covers cover the lamp grooves. With this arrangement, the light-emitting components are located at the top of the lamp body, so that the light generated at the top of the lamp can be scattered into the room through the ceiling, resulting in a good lighting atmosphere.

[0014] Furthermore, the light-emitting component includes an LED bead disposed at the bottom of the lamp slot and a polarizing lens. The polarizing lens is disposed above the LED bead, and the LED bead is located inside the lens cavity with an opening at the bottom of the polarizing lens. With this arrangement, the light generated by the LED bead is deflected and scattered outward through the polarizing lens, resulting in better indoor lighting effect. Attached Figure Description
