Description

Technical Field

[0001] This utility model relates to the field of lighting, specifically to an LED ceiling light that is easy to dissipate heat. Background Technology

[0002] Most commonly seen LED ceiling lights on the market today use a single, narrow, ring-shaped aluminum base panel structure, with lenses mounted on the surface of the LED chips for light distribution, while the driver power supply is usually installed in the center or on the side. However, this design has the following problems: First, because the aluminum-based lamp panel is small in area and the driver power supply is installed directly opposite the light-transmitting cover, it is easy to block the light and affect the uniformity of light output, resulting in dark areas in the lighting area. Although the lens light distribution can optimize the light distribution to a certain extent, it is still difficult to completely eliminate the phenomenon of uneven light spots.

[0003] Secondly, the narrow ring-shaped aluminum base lamp panel has a limited heat dissipation area, and the concentrated arrangement of LED beads on this structure will cause heat to accumulate. Furthermore, both the driver power supply and the lamp panel itself are heat sources, and the convergence of the two heat sources further affects the heat dissipation speed of the LED ceiling light. Long-term operation under such high temperature conditions will accelerate light decay and thus shorten the lifespan of the lamp. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides an LED ceiling light with easy heat dissipation, which has the beneficial effects of uniform light output, no dark areas, and easy heat dissipation.

[0005] The technical solution adopted by this utility model is as follows: A heat-dissipating LED ceiling light includes a light-transmitting cover 1, a first lamp plate 21, a second lamp plate 22, a chassis 3, a driving power supply 4, a first guide rail 51, and a second guide rail 52. The light-transmitting cover 1 is detachably installed on the chassis 3. The chassis 3 is provided with a concave power supply compartment that opens to its outer surface. The driving power supply 4 is placed in the concave power supply compartment. The concave power supply compartment protrudes to form a boss 31 on the inner surface of the chassis 3. The first lamp plate 21 is installed on the top surface of the boss 31. The second lamp plate 22 is installed on the horizontal surface of the inner surface of the chassis 3 excluding the area occupied by the boss 31. The first guide rail 51 is fixed to the outer surface of the chassis 3. The second guide rail 52 is fixed to the ceiling. The first guide rail 51 is slidably installed on the second guide rail 52.

[0006] Furthermore, the recessed power supply compartment is located in the middle of the chassis 3.

[0007] Furthermore, the concave power compartment is a hollow cylindrical shape.

[0008] Furthermore, the first light panel 21 is circular, the second light panel 22 is annular, the inner diameter of the second light panel 22 is larger than the diameter of the first light panel 21, and the outer diameter of the second light panel 22 is smaller than the diameter of the chassis 3.

[0009] Compared with the prior art, this utility model has the following advantages: (1) The recessed power supply compartment is provided on the outer surface of the chassis 3 to separate the two heat-generating elements, the lamp panel and the power supply, to avoid the phenomenon that the heat of the space where the light source is located is too high due to the heat accumulation caused by their simultaneous operation, thereby improving the service life of the ceiling light; at the same time, the recessed power supply compartment is provided with an opening to expand the heat dissipation space of the power supply, improve the heat dissipation efficiency, and facilitate subsequent maintenance of the power supply; in addition, the recessed design avoids occupying the space of the outer surface of the chassis 3, ensuring the aesthetics of the ceiling light installed behind the ceiling.

[0010] (2) By placing the power supply on the outer surface of the chassis 3, the occupancy rate of the lamp panel on the chassis 3 can be increased, the light-transmitting cover 1 can be fully utilized, the light output is more uniform, and the appearance of dark lighting areas is avoided.

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0014] Please refer to Figure 1-3 As shown, this utility model embodiment provides an easily heat-dissipating LED ceiling light, including a light-transmitting cover 1, a first lamp board 21, a second lamp board 22, a chassis 3, a driving power supply 4, a first guide rail 51, and a second guide rail 52.

[0015] The chassis 3 has an inner surface and an outer surface. The opening edge of the light-transmitting cover 1 is provided with a first thread. The inner surface edge of the chassis 3 has a raised side surface. The side surface of the inner surface of the chassis 3 is provided with a second thread that matches the first thread, so that the light-transmitting cover 1 can be detachably installed on the chassis 3. The light-transmitting cover 1 and the inner surface of the chassis 3 form a light source cavity.

[0016] The chassis 3 is circular and has a recessed power supply compartment with an opening on its outer surface. This recessed power supply compartment is located in the center of the chassis 3 and is hollow cylindrical in shape. The drive power supply 4 is housed within this recessed power supply compartment. Separating the light source from the drive power supply 4 prevents heat accumulation caused by simultaneous operation of the light source and power supply in the ceiling light, reducing the temperature of the space where the light source is located and extending the lifespan of the ceiling light. Simultaneously, the opening in the recessed power supply compartment expands the heat dissipation space of the power supply, improving heat dissipation efficiency and facilitating subsequent maintenance of the drive power supply 4. Furthermore, the recessed design avoids occupying space on the outer surface of the chassis 3, ensuring the aesthetic appearance of the ceiling light installed behind the ceiling.

[0017] The recessed power supply compartment protrudes from the inner surface of the chassis 3 to form a boss 31. The first lamp plate 21 is circular, and the second lamp plate 22 is annular. The inner diameter of the second lamp plate 22 is slightly larger than the diameter of the first lamp plate 21, and the outer diameter of the second lamp plate 22 is slightly smaller than the diameter of the chassis 3. The first lamp plate 21 is mounted on the top surface of the boss 31, and the second lamp plate 22 is mounted on the horizontal surface of the inner surface of the chassis 3 excluding the area occupied by the boss 31. The first lamp plate 21 and the second lamp plate 22 maximize their occupancy on the chassis 3, making full use of the light-transmitting cover 1, resulting in more uniform light output and avoiding the appearance of dark areas.

[0018] The chassis 3 is provided with a cable outlet hole for the power cord of the lamp panel to pass through. The chassis 3 is provided with a fixing hole. The first guide rail 51 is fixed to the outer surface of the chassis 3 by screws, and the second guide rail 52 is fixed to the ceiling by screws. The first guide rail 51 is slidably connected to the second guide rail 52.

[0019] LED beads are evenly soldered on the first lamp board 21 and the second lamp board 22 to further make the ceiling light emit light evenly. The input and output lines of the driving power supply 4 are electrically connected by plug-in terminals. When the ceiling light needs to be maintained, such as when the power supply is replaced, this embodiment does not require disassembling the entire ceiling light. The ceiling light can be removed by sliding the guide rail to see the power supply. Moreover, no installation tools are required. The power supply can be replaced by plugging and unplugging the terminals by hand.

[0020] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
