Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a panel lamp. Background Art

[0002] Panel lights are a type of lighting equipment, usually used for indoor lighting, especially in places that require uniform lighting, such as offices, shopping malls, homes, hospitals, etc. Conventional panel lights have a frame around the periphery of the lamp housing, and the lampshade is fixedly connected to the frame of the lamp housing. Generally, the lampshade and the frame are connected by snap-on connection, screw fixing connection or glue bonding.

[0003] For example, a Chinese utility model patent with application number 202321981198.7 discloses an all-plastic panel lamp, including a chassis and a diffuser plate. The chassis is provided with a accommodating cavity, and a plurality of light source boards and a driving board are provided in the accommodating cavity. The light source board is electrically connected to the driving board, and the driving board is connected to an input line. A plurality of lamp beads are provided on the light source board. A frame is provided on the outer side of the chassis. A glue groove is provided on the surface of the frame facing the light emitting surface. Glue is coated in the glue groove, and the bottom surface of the diffuser plate is bonded to the frame by glue.

[0004] In the above structure, the bottom surface of the diffuser plate is bonded to the frame by glue, which can hide the frame structure of the diffuser plate, so that only the diffuser plate is exposed on the entire installation surface, and the entire installation surface is neat and beautiful. However, the above structure still has the following problems: first, the firmness of the glue bonding needs to be verified; in addition, the above structure only does not see the frame on the installation surface, but actually has a frame, which is redundant in structure. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a frameless panel lamp with simple structure and reliable connection in view of the current status of the prior art.

[0006] The technical solution adopted by the utility model to solve the above-mentioned technical problems is: a panel lamp, including a lamp housing, a light-emitting component arranged in the lamp housing and a lampshade arranged below the lamp housing, the lamp housing including a shell top and a peripheral wall extending downward from the periphery of the shell top, the periphery of the peripheral wall extending outwardly with a first connecting plate, the periphery of the lampshade is bent inwardly to form a fourth connecting plate, and the first connecting plate is clamped in the gap between the fourth connecting plate and the upper surface of the lampshade.

[0007] In order to facilitate processing, the lamp housing is a metal housing, the lamp shade is a plastic plate, and the fourth connecting plate is formed by thermal deformation processing on the lamp shade. Thermal deformation processing of plastics mainly involves the processing methods of thermoplastic plastics and thermosetting plastics, which is a conventional processing method; in this embodiment, the lamp housing is a metal housing, and the thermal deformation processing temperature of plastics is usually much lower than the thermal processing temperature of metals, so thermal deformation processing on the lamp shade will not have adverse effects on the lamp housing.

[0008] In order to reduce the difficulty of forming the fourth connecting plate during the thermal deformation process, the top of the lamp housing is rectangular, and accordingly, the lampshade is also rectangular, and the fourth connecting plate extends from each side of the lampshade, and a second gap is provided between adjacent fourth connecting plates. The rectangular lampshade only needs to be thermally deformed on four sides, and each side can be simply bent; in other embodiments, the lampshade can also be a polygon with other side lengths; when the lampshade is thermally deformed on each side, redundant lampshade plastic plates will appear at the corners of adjacent sides. Before the thermal deformation process, the lampshade plastic plates at the corners of the adjacent sides of the lampshade can be cut off, for example, a rectangular lampshade plastic plate is cut off at each corner, so that a second gap is provided between adjacent fourth connecting plates.

[0009] In order to reduce the difficulty of thermal deformation processing, a second connecting plate extends upward from the outer edge of the first connecting plate, a third connecting plate extends upward from the periphery of the lampshade, and a fourth connecting plate extends inward from the end of the third connecting plate. The upper end of the second connecting plate abuts against the fourth connecting plate, and the lower end of the second connecting plate abuts against the upper surface of the lampshade.

[0010] Preferably, the fourth connecting plate is formed by thermal deformation of the third connecting plate. The third connecting plate can be stamped integrally with the lampshade, and during assembly, the third connecting plate only needs to be thermally deformed to form the fourth connecting plate.

[0011] Preferably, the third connecting plate is formed by thermal deformation processing on the lampshade. In this embodiment, the fourth connecting plate and the third connecting plate are both formed by thermal deformation processing.

[0012] Preferably, the top of the lamp housing is rectangular, and correspondingly, the lampshade is also rectangular, the third connecting plate and the fourth connecting plate extend on each side of the lampshade, the second gap is spaced between adjacent fourth connecting plates, and the first gap is spaced between adjacent third connecting plates.

[0013] Preferably, the peripheral wall extends downward and outward from the periphery of the shell top, and hooks for connecting with the outside are arranged on two opposite outer side walls of the peripheral wall.

[0014] Preferably, a junction box is provided on the outer side wall of the peripheral wall, and the side wall where the hook is located is adjacent to the side wall where the junction box is located.

[0015] Compared with the prior art, the utility model has the advantages of: no frame is required, the lampshade is directly connected to the lamp housing, and the structure of the panel lamp is simplified; in addition, the lampshade is bent and deformed to be connected with the lamp housing, and the two are firmly connected.

[0020] The lamp housing 1 is a metal housing having a rectangular housing top 11 . A peripheral wall 12 extends outward and downward from each side of the housing top 11 . A first connecting plate 121 extends horizontally outward from the periphery of the peripheral wall 12 . A second connecting plate 122 extends upward from the outer edge of the first connecting plate 121 .

[0021] The lampshade 3 is a plastic plate, and the lampshade 3 is roughly rectangular. A third connecting plate 31 first extends upward on each side of the lampshade 3, and the third connecting plate 31 extends inward to form a fourth connecting plate 32. The second connecting plate 122 is located in the gap between the fourth connecting plate 32 and the upper surface of the lampshade 3, and the upper end of the second connecting plate 122 of the lamp housing 1 abuts against the fourth connecting plate 32, and the lower end of the second connecting plate 122 abuts against the upper surface of the lampshade 3. The fourth connecting plate 32 is formed by heat deformation processing on the third connecting plate 31, and the third connecting plate 31 can be stamped and formed integrally with the lampshade, or can be formed by heat deformation processing on the lampshade 3.

[0022] On the lampshade 3, there is a first gap 31a between adjacent third connecting plates 31, and there is a second gap 32a between adjacent fourth connecting plates 32. In this embodiment, the third connecting plates 31 and the fourth connecting plates 32 are both formed by thermal deformation processing. Before the thermal deformation processing, the lampshade plastic plates at the corners of the adjacent sides of the lampshade are cut off, for example, a rectangular lampshade plastic plate is cut off at each corner. After the thermal deformation processing, there is a first gap 31a between adjacent third connecting plates 31; before the thermal deformation processing of the fourth connecting plates 32, the lampshade plastic plates are also cut off in a similar manner, so that there is a second gap 32a between adjacent fourth connecting plates 32.
