Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to an ultra-thin ceiling light. Background Technology

[0002] LED ceiling lights are a common lighting device widely used in various scenarios due to their high luminous efficacy, low power consumption, long lifespan, and ease of control. Existing ceiling lights include direct-emitting and side-emitting types. Side-emitting lights offer advantages such as a beautiful and simple appearance, a luxurious and elegant look, uniform and soft light emission, ultra-thin design, and convenient installation and transportation. However, achieving high luminous efficacy is difficult; currently, achieving around 120 lm / W requires significant cost. Additionally, panel lights using PS and MAS light guide plates may yellow over time. Direct-emitting lights, on the other hand, have the advantages of relatively simple technology and processes, with semi-automated production lines reducing labor costs. They offer sufficient brightness and are easy to achieve high luminous efficacy, currently reaching 135 lm / W, with minimal yellowing. They are also more affordable than side-emitting lights. The disadvantage is that the lamp body is relatively thicker. Utility Model Content

[0034] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0035] Reference Figures 1 to 11 The ultra-thin ceiling light of this utility model is illustrated in the following embodiments:

[0036] The ultra-thin ceiling light includes a chassis 100, a light source board 200, a lens module 300, and a lampshade 400.

[0037] The outer side of the chassis 100 is provided with a recessed heat dissipation groove 120. This groove serves two purposes: it avoids the mounting screws and it also helps dissipate heat when the chassis 100 is fixed to the ceiling. The recessed heat dissipation groove 120 is disc-shaped, but in some other implementations it may be rectangular or other shapes, depending on the specific circumstances.

[0038] The inner wall of the chassis 100 is provided with snap fasteners 110, and the outer wall of the lampshade 400 is provided with a groove 410 corresponding to the snap fasteners 110. The lampshade 400 and the chassis 100 are assembled by sliding engagement between the snap fasteners 110 and the grooves 410. In other words, the snap fasteners 110 on the side wall of the chassis 100 slide into the grooves 410 of the lampshade 400 for engagement, enabling rapid assembly of the lampshade 400 and the chassis 100. This improves assembly efficiency and reduces the use of screws. In this embodiment, the number of snap fasteners 110 corresponds to the number of grooves 410, and in this invention, there is no limitation on the number of snap fasteners 110 on the chassis 100 and the number of grooves 410 on the lampshade 400.

[0039] The light source plate 200 is arranged in a ring shape and is mounted on the chassis 100. Multiple light-emitting elements 210 are arranged in a ring around the light source plate 200. This ring-shaped arrangement results in a smaller area ratio, less material consumption, lower cost, and reduced overall weight of the lamp. Both the lens module 300 and the light source plate 200 are U-shaped. This allows for better coordination with the optical design of the lens body 310, the distance between the lampshade 400 and the light source, and the diffusion surface of the lampshade 400. This achieves uniform light distribution while reducing the number of light-emitting elements 210 and shortening the distance between the lampshade 400 and the light source plate 200, resulting in an ultra-thin 60mm design and lower costs. In some other embodiments, the light source plate 200 may also be ring-shaped.

[0040] Similarly, the lens module 300 is arranged in a ring shape and covers the light-emitting side of the light source plate 200. The lens module 300 has multiple lens bodies 310, which are arranged one-to-one with multiple light-emitting bodies 210. The lens body 310 covers the light-emitting body 210. In order to achieve a uniform light emission effect, the inner surface of the lens body 310 is a smooth curved surface 311. The inner surface of the lens body 310 has no protrusion structure, which reduces cost and facilitates production. The outer surface of the lens body 310 is a composite arc curved surface 312. The cross-section line formed by the composite arc curved surface 312 is a symmetrical parabolic structure, as shown in curve S2 and curve S3 of the lens body 310. The lamp cover 400 is connected to the chassis 100 and has a secondary light diffusion surface that convexes outward, as shown in curve S1 of the lamp cover 400. The functions of the three curves are shown in [reference needed]. Figure 9 , Figure 10 and Figure 11 The three diffusion surfaces work together to achieve uniform light output and an even thinner ultra-thin ceiling light effect. See details for specific effects. Figures 5 to 8 The rendering shows the effect. In summary, compared with existing LED ceiling lights, this utility model, through the combination of light source arrangement, self-designed lens, and 400mm diffuser surface of the lampshade, ultimately achieves an ultra-thin lamp with a simple structure, sufficient brightness, and easy high-gloss effect.

[0041] Specifically, an annular step 313 is provided on the opening side of the lens body 310. The light-emitting element 210 is located exactly at the middle of the annular step 313. At this time, an annular heat dissipation cavity 314 is formed between the light-emitting element 210 and the inner circumferential surface of the annular step 313. The annular heat dissipation cavity 314 can effectively dissipate heat and help reduce the heat generated by the light-emitting element 210 during operation.

[0042] The light emitter 210 has a disk-shaped structure and is in close contact with the opening of the smooth curved surface 311 of the lens body 310. This structural design allows all the light emitted by the light emitter 210 to be diffused through the smooth curved surface 311, thereby achieving a more uniform light distribution.

[0043] In addition, a retaining edge 330 extending towards the chassis 100 is provided on the outer side of the lens module 300. This retaining edge 330 can engage with the outer edge of the light source plate 200. This engagement structure not only facilitates the installation between the lens module 300 and the light source plate 200, but also plays a role in accurate positioning, ensuring the relative positional accuracy of the two during the installation process.

[0044] The inner wall of the chassis 100 is equipped with a power supply assembly 500, which includes a power drive module and a power housing. The power drive module is located inside the power housing. The power housing includes power housing fixing screws, a power housing top cover, and a power housing bottom cover. The bottom of the power housing top cover is connected to the top of the power housing bottom cover, and the power housing top cover and power housing bottom cover are fixed together by the power housing fixing screws to form the power housing. The chassis 100 has power housing mounting holes, through which the power housing bottom cover is mounted on the chassis 100, thus enabling the power housing to be mounted on the chassis 100.

[0045] The lens module 300 is provided with a port receiving slot 320, through which the power cable contacts the light source board 200. There are two port receiving slots 320, which are symmetrically arranged on the lens module 300. During installation, one of the port receiving slots 320 is aligned with the power supply assembly 500, and the power cable is connected to the power drive module.

[0046] The ultra-thin ceiling light also includes a metal grounding terminal 610 and a terminal fixing screw 620. The metal grounding terminal 610 has a screw hole, and the chassis 100 has a terminal mounting hole corresponding to the screw hole of the metal grounding terminal 610. The terminal fixing screw 620 first passes through the screw hole of the metal grounding terminal 610, and then screws into the terminal mounting hole of the chassis 100 to fix the metal grounding terminal 610 to the chassis 100.

[0047] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
