Description

Technical Field

[0001] This application relates to the field of lighting technology, and particularly to a low-cost panel light. Background Art

[0002] The existing lamp housing structure is a housing with an open lower end. This lamp housing with a closed upper end is made by stretching aluminum materials using a mold. The disadvantages of manufacturing the lamp housing by mold stretching are that the mold manufacturing cost is high and one set of mold can only produce lamp housings of one specification, with poor versatility and room for further improvement.

[0003] For this reason, a spliced lamp housing structure is designed, including an annular housing. A back plate is installed on the upper part of the annular housing, and a light-transmitting plate is installed on the lower part of the annular housing. The annular housing is composed of at least three sequentially connected profiles. The annular housing composed of profile splicing in the present utility model, together with the back plate and the light-transmitting plate, forms a complete lamp housing. The annular housing composed of profile splicing can cut the profiles according to different product shapes and sizes to realize splicing the profiles according to different product specifications, which not only saves the mold opening cost but also has good versatility.

[0004] However, both the back plate and the annular housing in the above-mentioned spliced lamp housing structure are made of aluminum profiles, with high material costs. And there are insertion grooves provided on the inner wall surface of the upper part of the profile, and the side of the back plate is inserted into the insertion groove, which is not convenient for assembly.

[0033] Referring to Figures 1 to 4 , embodiments of the present application are proposed. The low-cost flat panel lamp described in this embodiment includes:

[0034] A plastic bottom shell 1, including a bottom plate 11, and the four sides of the bottom plate 11 are bent downward to form an annular border 12. The annular border 12 and the bottom plate 11 enclose a space with an open lower end for accommodating a light-emitting component.

[0035] An annular metal bracket 20 is installed at the lower end of the annular border 12.

[0036] A diffusion plate 30 is installed at the lower end of the metal bracket 20.

[0037] In the present application, the metal bracket 20 is provided with a buckle for clamping with a ceiling keel. On the basis of ensuring that the flat panel lamp can be stably installed on the wall, the plastic bottom shell is designed to be made of plastic, preferably integrally formed by plastic injection molding, which is convenient for manufacturing and assembling and reduces material costs.

[0038] Preferably, a first annular groove 121 is provided at the lower end of the annular border 12, and an installation part 21 matching the first annular groove 121 is provided on the metal bracket 20. The installation part 21 extends into the first annular groove 121 and is connected to the annular border 12. After the installation part 21 extends into the first annular groove 121, a blocking structure is formed between the groove wall of the first annular groove 121 and the installation part 21. The blocking structure can prevent water flushing, which is beneficial to improving the waterproof performance of the flat panel lamp; at the same time, after the installation part 21 extends into the first annular groove 121, it is connected to the annular border 12, which is convenient for installation.

[0039] In this embodiment, after the second annular groove 211 extends into the first annular groove 121, the bottom plate 11 and the metal bracket 20 are connected by fasteners, which is convenient for installation. In another embodiment, as Figure 5 shown, a clamping structure is provided between the metal bracket 20 and the annular border 12 for clamping.

[0040] Based on the above, further, a second annular groove 211 is provided at the upper end of the installation part 21, and the second annular groove 211 extends into the first annular groove 121 to further improve the waterproof performance of the blocking structure.

[0041] In order to further improve the waterproof performance of the flat lamp, in this embodiment, a waterproof structure is also provided at the wire hole 40 of the bottom plate 11.

[0042] The waterproof structure includes a waterproof cover 50. An annular boss 60 surrounding the wire hole 40 is provided at the upper end of the bottom plate 11. A first semi-circular hole 61 is provided on one side of the boss 60. A second semi-circular hole 51 is provided on the side wall of the waterproof cover 50. The waterproof cover 50 is installed on the upper end of the bottom plate 11 and covers the boss 60. Referring to the attached Figure 2 As shown, the waterproof cover 50 is snap-fitted on the outer wall of the boss 60, and a through hole for the wire 70 to pass through and abut against the wire 70 is formed by enclosing between the first semi-circular hole 61 and the second semi-circular hole 51.

[0043] A light-emitting component is arranged in the space. The wire 70 on the light-emitting component passes through the wire hole 40 and then passes out from the through hole. The waterproof cover 50 covers the wire 70 inside it, and the outer wall of the wire 70 abuts against the hole wall of the through hole to form a first-level waterproof structure.

[0044] Based on the above, further, a first rib 80 is provided between the wire hole 40 and the through hole at the upper end of the bottom plate 11. A second rib 90 is provided on the top wall of the waterproof cover 50. The waterproof cover 50 is installed on the upper end of the bottom plate 11 and the first rib 80 and the second rib 90 are vertically corresponding and enclose a hole matching the wire 70. When the wire passes through the wire hole 40 and the through hole, the first rib 80 and the second rib 90 abut against the wire 70 to form a second-level waterproof structure.

[0045] Based on the above, in this application, the waterproof structure further includes a sealing ring 100. The sealing ring 100 is used to be sleeved on the wire 70 and abut against the first rib 80 and the second rib 90 to form multi-level waterproofing and improve the waterproof performance.

[0046] In this embodiment, an opening matching the shape of the diffusion plate 30 is provided at the lower end of the metal bracket 20. The diffusion plate 30 is arranged at the opening and connected to the metal bracket 20. The diffusion plate 30 can be installed at the opening at the lower end of the metal bracket 20 by adhesion, maximizing the light-emitting area of the flat lamp, improving the light efficiency of the flat lamp, and being more energy-efficient.

[0047] Certainly, the present utility model is not limited to the above embodiments. Those skilled in the art can make equivalent deformations or substitutions without departing from the spirit of the present utility model, and these equivalent deformations and substitutions are all included in the scope defined by the claims of this application.
