Description

Technical Field

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

[0002] LED flat panel light is a high-end indoor lighting fixture. Its outer frame is made of anodized aluminum alloy and the light source is LED. The whole lamp is beautifully designed, simple, and luxurious. The light passes through the high-transmittance light guide plate to form a uniform planar luminous effect. The illumination is uniform, the light is soft, comfortable and bright, and can effectively relieve eye fatigue.

[0003] At present, flat panel lights basically include an outer frame, a light source mounting plate and a light guide plate, wherein the light source mounting plate is provided with an LED lamp. When the light source mounting plate is connected to the outer frame, it is mostly screwed, which makes the operation more complicated and inconvenient to operate when disassembling for maintenance. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide an LED flat panel lamp with a simple structure, strong stability and easy disassembly.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] An LED flat panel lamp comprises an outer frame, a light source mounting plate and a light guide plate, wherein an LED light source is mounted on the light source mounting plate, the outer frame is annular and protrudes inward to form an annular supporting platform, the light guide plate is placed on the supporting platform, plug plates are arranged at circumferential intervals on the light source mounting plate, and a clamping structure for clamping the plug plates is fixedly mounted on the outer frame.

[0007] In this way, during the assembly process or the inspection and maintenance of the flat panel lamp, when the light source mounting plate and the outer frame need to be disassembled, the clamping structure releases the clamping of the plug-in board, and the light source mounting plate can be removed. This can be done directly manually without the need for additional tools, which greatly improves convenience.

[0008] Among them, the clamping structure includes a clamping frame with the same number as the plug-in boards, the clamping frame is fixedly installed on the outer frame, the clamping frame is in an inverted L shape, a slot that can be plugged and matched with the plug-in board is formed between the clamping frame and the outer frame, an internal threaded barrel is fixed on the clamping frame, and a clearance hole is provided through the internal threaded hole of the outer frame facing the internal threaded barrel, and the clamping bolt cooperates with the internal threaded barrel and is clamped on the plug-in board.

[0009] Wherein, the light source mounting plate is arranged to protrude upwards.

[0010] Wherein, the supporting platform is concave to form an annular groove, and a sealing strip is fixed in the annular groove.

[0011] Among them, the outer frame is integrally formed.

[0012] In summary, the LED flat lamp of the present invention has the advantages of simple structure, strong stability and convenient disassembly. Description of the Drawings

[0013] Figure 1 It is a schematic structural diagram of an LED flat lamp according to the present invention.

[0014] Figure 2 It is Figure 1 the front view of

[0015] Figure 3 It is Figure 2 the A-A cross-sectional view of

[0016] Figure 4 It is Figure 1 the enlarged schematic view at B of

[0017] Figure 5 It is Figure 1 the schematic view of another orientation after removing the light guide plate. Detailed Description of the Embodiment

[0018] The present invention will be further described in detail below with reference to the drawings. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the orientation words such as "upper, lower" and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, so it cannot be understood as a limitation on the protection scope of the present invention; the orientation words "inner, outer" refer to the inside and outside relative to the contour of each component itself.

[0019] As Figures 1-5 shown, an LED flat lamp includes an outer frame 1, a light source mounting plate 2 and a light guide plate 3. An LED light source 4 is mounted on the light source mounting plate. The outer frame is annular and protrudes inward to form an annular supporting platform. The light guide plate is placed on the supporting platform. Plug plates 5 are arranged at intervals in the circumferential direction of the light source mounting plate. A pressing structure for pressing the plug plates is fixedly mounted on the outer frame.

[0020] In this way, during the assembly process or the maintenance process of the flat lamp, when it is necessary to disassemble the light source mounting plate from the outer frame, the pressing structure releases the pressing on the plug plates, and then the light source mounting plate can be removed. It can be directly manually operated without additional tools, which greatly improves the convenience.

[0021] During implementation, the clamping structure includes a clamping frame 6 with the same number as the plug-in boards. The clamping frame is fixedly mounted on the outer frame and is in an inverted L shape. A slot that can be plugged and matched with the plug-in board is formed between the clamping frame and the outer frame. An internal threaded barrel is fixed on the clamping frame. A clearance hole is provided through the internal threaded hole of the outer frame facing the internal threaded barrel. The clamping bolt 7 cooperates with the internal threaded barrel and is clamped on the plug-in board. When connecting, place the plug-in board directly between the two clamping frames, the plug-in board abuts against the light guide plate, rotate the light source mounting plate so that the plug-in board rotates into the slot between the clamping frame and the frame, and then rotate the clamping bolt so that the clamping bolt passes through the clearance hole and is clamped on the light source mounting plate to complete the connection. When disassembling, loosen the clamping bolt, rotate the light source mounting plate, and turn the plug-in board out from under the bracket to remove the light source mounting plate.

[0022] During implementation, the light source installation plate is arranged to protrude upwards, so that the light source installation plate and the light guide plate are arranged at a distance, thereby preventing the heat of the light source from damaging the light guide plate.

[0023] During implementation, the support platform is concave to form an annular groove, and a sealing strip is fixed in the annular groove to prevent light leakage.

[0024] During implementation, the outer frame is integrally formed to facilitate processing.

[0025] Finally, it should be noted that those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include these modifications and variations.
