Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and in particular to an LED ceiling light that facilitates heat dissipation. Background Technology

[0002] Ceiling lights are lighting fixtures embedded in the ceiling, projecting light downwards. In terms of price, ceiling lights using energy-saving lamps as their light source are more common than LED ceiling lights; however, in terms of luminous efficacy, LED ceiling lights are far superior to traditional energy-saving lamps. An LED ceiling light typically includes a lamp housing, reflector, LED light source, heat sink, and power driver.

[0003] Existing LED ceiling lights generally have the following problems: First, the LED light source and power driver are integrated inside the housing. As a result, the heat generated by the LED light source and power driver will accumulate inside, which can easily lead to overheating. Second, existing LED ceiling lights are installed on the ceiling using elastic fasteners. The position of these elastic fasteners cannot be adjusted, resulting in poor adaptability to different ceiling types. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an LED ceiling light that facilitates heat dissipation.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] An LED ceiling light includes a reflector, a heat sink detachably mounted on the upper end of the reflector, a light source assembly disposed within the reflector, a power driver disposed on the upper surface of the heat sink, and two sets of mounting fasteners arranged on the left and right sides, wherein the heat sink or reflector is connected and fixed to the mounting fasteners.

[0007] In a preferred embodiment of this utility model, the radiator is a metal plate, and the edge of the radiator is provided with a plurality of heat dissipation fins at intervals.

[0008] In a preferred embodiment of this utility model, a support column is provided on the upper surface of the heat sink, and the power driver is supported on the support column so that a gap is left between the power driver and the heat sink.

[0009] In a preferred embodiment of this utility model, the lower end of the reflector cup is provided with an outwardly extending horizontal baffle, and the upper surface of the horizontal baffle is provided with an elastic buffer sheet.

[0010] In a preferred embodiment of this utility model, the elastic buffer sheet is a sponge sheet.

[0011] In a preferred embodiment of the present invention, the edge of the radiator is provided with a base plate, the mounting fastener includes a torsion spring and a torsion spring mounting plate that can be moved up and down on the base plate, the base plate is provided with a fastener that can lock the torsion spring mounting plate, the torsion spring mounting plate is provided with a transverse locking block, the torsion spring includes an annular body sleeved on the transverse locking block and two torsion arms, the two torsion arms being arranged one in front of the other.

[0012] In a preferred embodiment of this utility model, the fastener is a threaded fastener, the base plate is provided with a transverse through hole through which the threaded fastener can pass, and the torsion spring mounting plate is provided with a vertical elongated hole corresponding to the transverse through hole. The threaded fastener passes through the transverse through hole and the vertical elongated hole to lock the base plate and the torsion spring mounting plate.

[0013] The beneficial effects of this utility model are: the LED ceiling light has the power driver installed outside the reflector cup, which separates the power driver and the light source assembly, making heat dissipation easier. At the same time, the power driver is located above the heat sink, which can effectively utilize the space between the ceiling and the floor slab. Attached Figure Description

[0017] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings.

[0018] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indicator will also change accordingly. Furthermore, descriptions involving "preferred," "second-preferred," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "preferred" or "second-preferred" may explicitly or implicitly include at least one of those features.

[0019] Reference Figures 1 to 3This utility model proposes an LED ceiling light, including a reflector cup 1, a heat sink 2 detachably installed on the upper end of the reflector cup 1, a light source assembly 8 disposed in the reflector cup 1, a power driver 3 disposed on the upper surface of the heat sink 2, and two sets of mounting fasteners arranged on the left and right sides, wherein the heat sink 2 or the reflector cup 1 is connected and fixed to the mounting fasteners.

[0020] The heat sink 2 is a metal plate, and multiple heat dissipation fins 21 are spaced apart along the edge of the heat sink 2. The light source assembly 8 includes a lamp plate 7 that is attached to the lower surface of the heat sink 2 and LED beads disposed on the lower surface of the lamp plate.

[0021] Preferably, the reflector 1 and the radiator 2 are screwed together. The screwing method can be: 1. The reflector 1 is made of plastic, with a vertical through hole at its upper end for mounting bolts. The radiator 2 has a corresponding vertical through hole for mounting bolts, and the two are locked together using bolts and nuts. 2. The reflector 1 is made of metal, with at least three connecting pieces welded to its upper edge, and the radiator 2 is screwed together with these connecting pieces.

[0022] The LED ceiling light has the power driver 3 installed outside the reflector cup 1, which separates the power driver 3 from the light source assembly 8, making heat dissipation easier. At the same time, the power driver 3 is located above the heat sink 2, which can effectively utilize the space between the ceiling and the floor slab.

[0023] Furthermore, a support column 22 is provided on the upper surface of the heat sink 2, and the power driver 3 is supported on the support column 22 to leave a gap between the power driver 3 and the heat sink 2. The power driver 3 is connected to the support column 22 by screws. This design can further improve the heat dissipation efficiency of the heat sink 2.

[0024] Reference Figure 1 and Figure 3 The lower end of the reflector cup 1 is provided with an outwardly extending horizontal baffle 11, and the upper surface of the horizontal baffle 11 is provided with an elastic buffer sheet 4. Preferably, the elastic buffer sheet 4 is a sponge sheet. When the ceiling light is installed on the ceiling, the elastic buffer sheet 4 is located between the horizontal baffle 11 and the ceiling, which can form a buffer and avoid rigid contact between the two to prevent indentation.

[0025] Reference Figure 3The heat sink 2 has a base plate 5 at its edge, and the heat sink 2 is screwed or welded to the base plate 5. The mounting fastener includes a torsion spring 62 and a torsion spring mounting plate 61 that is movably mounted on the base plate 5. The base plate 5 has fasteners that can lock the torsion spring mounting plate 61. The torsion spring mounting plate 61 has a transverse locking block 611. The torsion spring 62 includes an annular body fitted onto the transverse locking block 611 and two torsion arms, which are arranged one in front of the other. When the ceiling light is installed on the ceiling, the two torsion arms of each torsion spring 62 press against the upper surface of the ceiling panel to provide support for the LED ceiling light.

[0026] Furthermore, the fasteners are threaded fasteners, such as screw assemblies, bolt assemblies, etc. The base plate 5 has a transverse through hole 51 through which the threaded fasteners can pass, and the torsion spring mounting plate 61 has a vertical elongated hole 612 corresponding to the transverse through hole 51. The threaded fasteners pass through the transverse through hole 51 and the vertical elongated hole 612 to lock the base plate 5 and the torsion spring mounting plate 61 together. This design allows the vertical position of the torsion spring 62 to be adjusted. By adjusting the vertical position of the torsion spring 62, the resistance force between the torsion spring 62 and the ceiling can be adjusted, keeping this resistance force within a reasonable range.

[0027] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
