Description

Technical Field

[0001] This utility model relates to the field of LED panel light technology, and more specifically, to an LED panel light. Background Technology

[0002] LED panel lights are planar lighting fixtures that use LEDs as the light source. They are characterized by their ultra-thinness, high brightness, and uniform light distribution, and are widely used in commercial, office, and residential indoor lighting applications. During routine highway maintenance, workers need to use ditch cleaning devices to clean the roadside ditches. For example, the LED panel light disclosed in publication number "CN103939774A" includes an outer frame, a lampshade, a panel, and a top cover. The lampshade is installed below the outer frame, the panel is located above the lampshade, and the top cover is installed above the panel. A power connection device is provided on the back of the top cover. Several LED beads are installed on the lower surface of the panel, and a reflective layer is also covered on the lower surface of the panel.

[0003] However, in the above technical solution, the LED panel light will accumulate a lot of dust on the surface of the lampshade after long-term use. It is necessary for staff to use ladders to move to a high place to clean the lampshade. This not only requires additional manpower, but climbing the ladder may also cause safety accidents such as falls and slips. Utility Model Content

[0004] The main purpose of this utility model is to provide an LED panel light that can effectively solve the problem that in the background technology, after a long period of use, the surface of the LED panel light will accumulate a lot of dust, requiring workers to use ladders to move to a high place to clean the light cover. This not only requires additional manpower, but also poses a safety accident such as falling or slipping when climbing the ladder.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An LED panel light includes a mounting back plate, a circuit board disposed inside the mounting back plate, a plurality of bulbs electrically disposed on the lower surface of the circuit board, a clamping plate fixedly mounted on the outer wall of the mounting back plate, a connecting groove being formed through the upper surface of the clamping plate, a lampshade fixedly mounted on the lower surface of the mounting back plate, a cleaning component for cleaning the lampshade disposed in the connecting groove, and a lifting component for driving the cleaning component to rise and fall on the upper surface of the mounting back plate.

[0007] Preferably, the cleaning assembly includes a lifting frame, which is slidably disposed in a connecting groove. Positioning frames are fixedly installed on both sides of the upper surface of the lifting frame. A lead screw is rotatably installed between the two sides of the inner wall of one of the positioning frames. A movable plate is threaded on one side of the lead screw. Connecting frames are fixedly installed on both sides of the upper surface of the movable plate. A brush roller is disposed between the two sides of the inner wall of the connecting frame.

[0008] A first motor is fixedly installed on one side of the positioning frame near the lead screw, and one end of the lead screw passes through the corresponding positioning frame and is fixedly connected to the output shaft end of the first motor.

[0009] Preferably, a positioning rod is fixedly installed between the two sides of the inner wall of another positioning frame, and the movable plate is slidably disposed on one side of the positioning rod.

[0010] Preferably, a rack is fixedly installed between the two sides of the inner wall of the positioning frame near the lead screw, and a crossbar is rotatably installed between the two sides of the inner wall of the connecting frame, with the brush roller sleeved on the crossbar.

[0011] One end of the crossbar passes through the connecting frame and is fitted with a gear, which meshes with the rack.

[0012] Preferably, the lifting assembly includes a second motor, which is fixedly mounted on one side of the upper surface of the mounting back plate. A threaded column is fixedly mounted on the output shaft end of the second motor, and a movable frame is threaded on one side of the column. The lower surface of the movable frame is fixedly connected to the lifting frame on both sides.

[0013] Preferably, a vertical pole is fixedly installed on the other side of the upper surface of the mounting back plate, and the movable frame is slidably disposed on one side of the vertical pole.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) By activating the lifting component, the staff can drive the lifting frame to descend, so that the connecting frame and brush roller are lowered to the lampshade position. Then, the staff can start the first motor, so that its output shaft drives the lead screw to rotate. The rotating lead screw drives the moving plate to move along the positioning rod through the screw thread, so that the moving plate drives the brush roller to move, so that the brush roller can clean the dust on the surface of the lampshade. This eliminates the need for staff to climb up and clean manually, avoids safety accidents, and reduces the workload of staff. Attached Figure Description

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0023] like Figures 1-5 As shown, an LED panel light includes a mounting back plate 1, a circuit board 2 disposed inside the mounting back plate 1, a plurality of bulbs 3 electrically disposed on the lower surface of the circuit board 2, a clamping plate 4 fixedly mounted on the outer wall of the mounting back plate 1, a connecting groove 5 through-cut on the upper surface of the clamping plate 4, a lampshade 6 fixedly mounted on the lower surface of the mounting back plate 1, a cleaning component 7 for cleaning the lampshade 6 disposed in the connecting groove 5, and a lifting component 8 for driving the cleaning component 7 to rise and fall on the upper surface of the mounting back plate 1.

[0024] The cleaning component 7 includes a lifting frame 701, which is slidably disposed in the connecting groove 5. Positioning frames 702 are fixedly installed on both sides of the upper surface of the lifting frame 701. A lead screw 703 is rotatably installed between the two sides of the inner wall of one of the positioning frames 702. A movable plate 704 is threaded on one side of the lead screw 703. A connecting frame 705 is fixedly installed on both sides of the upper surface of the movable plate 704. A brush roller 706 is disposed between the two sides of the inner wall of the connecting frame 705.

[0025] A first motor 707 is fixedly installed on one side of the positioning frame 702 near the lead screw 703. One end of the lead screw 703 passes through the corresponding positioning frame 702 and is fixedly connected to the output shaft end of the first motor 707.

[0026] Another positioning frame 702 has a positioning rod 708 fixedly installed between the two sides of the inner wall, and a movable plate 704 is slidably set on one side of the positioning rod 708.

[0027] The worker engages the mounting plate 4 with the ceiling keel structure, allowing them to secure the mounting back plate 1. Then, the worker supplies power to the power board, illuminating the bulb 3. Next, the worker activates the lifting assembly 8, which drives the lifting frame 701 to descend, lowering the connecting frame 705 and brush roller 706 to the lampshade 6. The worker then starts the first motor 707, causing its output shaft to rotate the lead screw 703. The rotating lead screw 703, through its threaded operation, moves the moving plate 704 along the positioning rod 708, causing the brush roller 706 to move and clean the dust from the lampshade 6. This eliminates the need for manual cleaning by workers climbing to a height, preventing accidents and reducing workload.

[0028] After cleaning is completed, the staff controls the brush roller 706 to reset, and then activates the lifting assembly 8 to drive the lifting frame 701 to reset, so as to prevent the lifting frame 701 from blocking the light source.

[0029] In another embodiment of the present invention, a rack 9 is fixedly installed between the two sides of the inner wall of the positioning frame 702 near the lead screw 703, and a crossbar 10 is rotatably installed between the two sides of the inner wall of the connecting frame 705, and a brush roller 706 is sleeved on the body of the crossbar 10.

[0030] One end of the crossbar 10 passes through the connecting frame 705 and is fitted with a gear 11, which meshes with the rack 9.

[0031] When the brush roller 706 moves, under the meshing action of the gear 11 and the rack 9, the gear 11 drives the crossbar 10 to rotate, so that the brush roller 706 rotates with the crossbar 10 as the reference, which increases the friction between the brush bristles on the surface of the brush roller 706 and the surface of the lampshade 6, so that the dust falls off more fully and the cleaning effect is improved.

[0032] In another embodiment of the present invention, the lifting assembly 8 includes a second motor 801, which is fixedly installed on one side of the upper surface of the mounting back plate 1. A threaded column 802 is fixedly installed on the output shaft end of the second motor 801. A movable frame 803 is threaded on one side of the column body of the threaded column 802. The two sides of the lower surface of the movable frame 803 are fixedly connected to the lifting frame 701.

[0033] A pole 804 is fixedly installed on the other side of the upper surface of the mounting back plate 1, and a movable frame 803 is slidably set on one side of the pole 804.

[0034] The staff started the second motor 801, which caused its output shaft to drive the threaded column 802 to rotate. The rotating threaded column 802 drove the moving frame 803 to rise and fall along the direction of the upright 804 by the threaded advance, so that the lifting frame 701 could drive the brush roller 706 to rise and fall.

[0035] The working principle of this type of LED panel light:

[0036] In use, the staff engages the clamping plate 4 with the ceiling keel structure, allowing them to secure the mounting back plate 1. Then, the staff supplies power to the power board, illuminating the bulb 3. Next, the staff activates the lifting assembly 8, which drives the lifting frame 701 to descend, lowering the connecting frame 705 and brush roller 706 to the lampshade 6. The staff then starts the first motor 707, causing its output shaft to rotate the lead screw 703. The rotating lead screw 703, through threaded screwing, moves the moving plate 704 along the positioning rod 708, causing the moving plate 704 to move the brush roller 706. This allows the brush roller 706 to clean the dust from the surface of the lampshade 6, eliminating the need for staff to climb and manually clean, thus preventing accidents and reducing workload.

[0037] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
