Technical Field
[0001] This utility model relates to the field of panel light technology, and more specifically, to a waterproof and dustproof double-sided light-emitting panel light. Background Technology
[0002] LED panel lights are aesthetically pleasing, simple, and luxurious. With their excellent illuminance uniformity, soft and even light, and comfortable lighting effect, they can effectively relieve eye fatigue. They are widely used in offices, schools, hospitals, shopping malls, homes, and other places. They are the best product to replace traditional fluorescent tubes and grid light panels in the LED era. According to the light emission mode, LED panel lights can be divided into two categories: side-emitting and direct-lit.
[0003] A search revealed a Chinese patent application with patent number 202021932983.X, which discloses a side-emitting panel light. The light includes a frame, a light source plate circumferentially fixed to the inner walls of the frame, a detachable back plate fixed to the upper part of the frame, and reflective paper, a light guide plate, and a diffuser plate arranged sequentially from top to bottom inside the frame. It also includes a first flexible sealing ring, a second flexible sealing ring, and an EVA buffer pad. This invention achieves a flexible seal between the first flexible sealing ring and the diffuser plate to prevent water from entering the frame from the diffuser plate, and a similar flexible seal between the second flexible sealing ring and the back plate to prevent water from entering the frame from the back plate. The EVA buffer pad provides a tight seal, achieving waterproofing without the need for glue. This simplifies production steps, reduces labor costs, and effectively avoids the scrapping of the light guide plate and light source plate, thus reducing production costs. Furthermore, the detachable design makes maintenance convenient. However, the aforementioned patents have the following shortcomings: after long-term use, the first and second flexible sealing rings will age and deform, leading to localized sealing failure and allowing moisture to easily penetrate the interior of the frame. Therefore, this utility model proposes a new solution. Utility Model Content

[0028] 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, not all, of the embodiments of this utility model.
[0029] like Figures 1-6As shown, this embodiment proposes a waterproof and dustproof dual-sided light-emitting panel lamp, including a frame 1, a light source plate 9 circumferentially fixed to the inner wall of the frame 1, a back plate 6 detachably installed on the upper part of the frame 1, and reflective paper 4, a light guide plate 3, and a diffuser plate 2 arranged sequentially from top to bottom inside the frame 1. An EVA buffer pad 5 is provided between the reflective paper 4 and the back plate 6. A first groove 12 circumferentially distributed is opened at the bottom of the inner wall of the frame 1, and a first flexible sealing ring 7 is installed inside the first groove 12. The top of the inner wall of the frame 1 is opened... The frame 1 includes a second groove 13 arranged in a ring, with a second flexible sealing ring 8 disposed inside the second groove 13. A third groove 14 arranged in a ring is located on the bottom of the inner wall of the frame 1, outside the first groove 12. A fourth groove 16 arranged in a ring is located on the top of the frame 1, inside the second groove 13. The frame also includes a first absorption ring 15, detachably installed inside the third groove 14, which absorbs air entering the frame from the gap between the diffuser plate 2 and the frame 1. Moisture inside body 1; second absorption ring 17, detachably installed inside the second absorption ring 17, the second absorption ring 17 is used to absorb moisture entering the frame 1 from the gap between the back plate 6 and the frame 1. The first absorption ring 15 and the second absorption ring 17 can be made of water-absorbing material. In use, the first flexible sealing ring 7 and the second flexible sealing ring 8 can ensure the sealing of the frame 1 and prevent moisture and dust from entering the frame 1. At the same time, the first absorption ring 15 and the second absorption ring 17 can also absorb moisture passing through the first flexible sealing ring 7 and the second flexible sealing ring 8, thereby solving the problem that external moisture can easily enter the frame 1 when the first flexible sealing ring 7 and the second flexible sealing ring 8 fail to seal locally due to aging and deformation. This can effectively improve the service life of the panel light. At the same time, the detachable first absorption ring 15 and the second absorption ring 17 can be easily replaced; elastic limiting cylinder 20, fixedly connected to the bottom of the back plate 6, and the top of the frame 1 is provided with a fifth groove 18 for accommodating the elastic limiting cylinder 20.The inner wall of the fifth groove 18 is fixedly equipped with multiple evenly distributed locking blocks 19. The outer wall of the elastic limiting cylinder 20 has a locking groove 21 that cooperates with the locking blocks 19. With the locking blocks 19, the elastic limiting cylinder 20, and the locking groove 21, when installing the back plate 6, simply align the elastic limiting cylinder 20 with the fifth groove 18 and press it down, so that the locking blocks 19 are locked in the locking groove 21 on the outer wall of the elastic limiting cylinder 20. This completes the fixation between the frame 1 and the back plate 6 without the need for screws, thus facilitating the installation and removal of the back plate 6. It also allows for easy replacement of the first flexible sealing ring 7, the second flexible sealing ring 8, the first absorption ring 15, and the second absorption ring 17 during use. During use, the multiple locking blocks 19 inside the locking groove 21 also block moisture and dust, thereby assisting the second flexible sealing ring 8 in improving the seal between the frame 1 and the back plate 6, further preventing moisture and dust from entering the interior of the frame 1 through the gap between the frame 1 and the back plate 6.
[0030] like Figures 1-4 As shown, in a preferred embodiment, based on the above method, the back plate 6 is further provided with a mounting hole 22, and a connector 11 that mates with the light source board 9 is installed inside the mounting hole 22. It should be noted that the mounting hole 22 facilitates the installation of the connector 11, and the connector 11 facilitates the connection between the light source board 9 and the driving power supply.
[0031] like Figure 4 and Figure 5 As shown, in a preferred embodiment, based on the above method, the connector 11 further includes a housing 111 that passes through the mounting hole 22 through the back plate 6. Multiple wires 114 are disposed inside the housing 111, and a waterproof adhesive 112 is provided inside the housing 111. A limiting switch 113 located at the bottom of the back plate 6 is threadedly connected to the outer side of the housing 111. It should be noted that tightening the limiting switch 113 during use will cause the housing 111 to fit tightly against the top of the back plate 6, preventing moisture from entering the interior of the frame 1 through the mounting hole 22. The waterproof adhesive 112 seals the wires 114 and the housing 111, preventing moisture or dust from entering the interior of the frame 1.
[0032] like Figure 3 and Figure 6As shown, in a preferred embodiment, based on the above method, a circumferentially distributed limiting platform 23 is further fixedly installed on the bottom of the inner wall of the frame 1. The limiting platform 23 is used to accommodate the diffuser plate 2. The limiting platform 23 is located on one side of the third groove 14. A sixth groove 24 is opened on the side wall of the limiting platform 23 facing the diffuser plate 2. An L-shaped sealing gasket 25 is fixedly installed inside the sixth groove 24. It should be noted that by setting the limiting platform 23, the position of the diffuser plate 2 can be restricted, preventing the diffuser plate 2 from becoming loose. By setting the sealing gasket 25, the inner wall of the limiting platform 23 and the edge of the diffuser plate 2 can be sealed, thereby improving the overall sealing performance in conjunction with the first flexible sealing ring 7, and further preventing moisture and dust from entering through the gap between the diffuser plate 2 and the frame 1.
[0033] like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, the top of the frame 1 is further connected with a plurality of hanging rings 10 evenly distributed on the outer side of the back plate 6. It should be noted that the hanging rings 10 facilitate the installation of the panel light.
[0034] Specifically, the working principle of this waterproof and dustproof double-sided luminous panel light is as follows: During use, the panel light is fixed to the ceiling or embedded in the suspended ceiling using the hanging ring 10 or conversion frame. The light source board 9 and the driver power supply are then connected via connector 11. After the driver power supply supplies power to the light source board 9, the LED beads on the light source board 9 will emit light and form side light. The side light converges in the light guide plate 3 and is refracted downwards by the reflective paper 4, finally scattering outwards through the diffuser plate 2. When installing the back plate 6, simply align the elastic limiting cylinder 20 with the fifth groove 18 and press it down, so that the locking block 19 is locked in the slot 21 on the outer wall of the elastic limiting cylinder 20, thus completing the installation of the frame 1 and the back plate 6. The back panel 6 is fixed together. When it is necessary to remove the back panel 6, it can be attached to the top of the back panel 6 by suction cup. Pulling the back panel 6 will allow the locking block 19 to be released from the inside of the locking slot 21. During use, the first flexible sealing ring 7, the second flexible sealing ring 8 and the sealing gasket 25 can ensure the sealing of the frame 1 and prevent moisture and dust from entering the interior of the frame 1. When the first flexible sealing ring 7 and the second flexible sealing ring 8 experience partial sealing failure due to aging or deformation, the first absorption ring 15 and the second absorption ring 17 can absorb the moisture that passes through the first flexible sealing ring 7 and the second flexible sealing ring 8, preventing moisture from directly entering the interior of the frame 1 and extending the service life of the panel light.
[0035] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
