Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

As shown in fig. 1 and 2, the LED flat lamp includes a frame 1, an LED strip and a light guide plate assembly 2, the frame 1 includes a plurality of sectional materials 11 connected end to end in sequence, and two adjacent sectional materials 11 are inserted into the same corner fitting 12 and fixed to each other.

As shown in fig. 3, 4 and 5, the profile 11 comprises, in cross section: corner portions, edge portions 112, and mounting portions. A first slot 111 is provided at the corner portion, and an insertion column 121 engaged with the first slot 111 is provided on the corner member 12. The rim 112 extends in the bezel thickness direction from the corner portions. The mounting portion extends from the corner portion to the inner side of the frame, in the mounting portion, a wire passing groove 113, a lamp groove 114 for accommodating the LED lamp strip, and a clamping groove 115 for accommodating the edge of the light guide plate assembly 2 are sequentially arranged from the corner portion to the inner side of the frame, wherein the wire passing groove 113 is open toward the edge portion, the lamp groove 114 and the clamping groove 115 are communicated with each other, and the clamping groove 115 is open toward the inner side of the frame.

Two adjacent section bars 11 are connected through corner pieces 12, a plurality of section bars 11 and corner pieces 12 are alternately connected to form a frame 1, and each edge of the light guide plate component 2 is inserted into the clamping groove 115 of the corresponding section bar 11, so that each part of the edge of the light guide plate component 2 is surrounded by the frame 1.

When the profile 11 and the corner fitting 12 are butted, the plug-in column 121 on the corner fitting 12 is inserted into the first slot 111 on the profile 11. At least two insertion columns 121 are arranged on the same corner fitting 12 to connect two adjacent section bars 11.

The LED lamp strip is arranged in the lamp strip groove 114, and the LED lamp strips in different sectional materials 11 are connected with a circuit by virtue of the wires in the wire passing grooves 113.

The holding groove 115 holds and fixes the upper and lower surfaces of the light guide plate assembly 2, and the side surface of the light guide plate assembly 2 is opposite to the wire passing groove 113. Through setting up lamp trough 114 and centre gripping groove 115 intercommunication each other, the light that can make the LED lamp area send penetrates light guide plate subassembly 2 through the distance as short as possible, reduces the scattering loss of light source through the optical path that shortens this section, and is more energy-conserving.

When the dull and stereotyped lamp of LED broke down, take out profile 11 with corner fittings 12, take out profile 11 with light guide plate subassembly 2, can expose LED lamp area and its connecting circuit in maintenance personal's the field of vision, conveniently find out the trouble reason.

In order to enhance the structural strength of the frame 1, in one embodiment, as shown in fig. 3, 4 and 5, a rib 116 is disposed on an outer wall of the first slot 111 facing the edge portion, and a second slot 122 for receiving the rib 116 is disposed on the corner member 12.

The ribs 116 extend along the length of the profile 11 and increase the strength of the profile 11. When the insertion column 121 is inserted into the first slot 111, the two ends of the rib 116 are inserted into the second slot 122, which increases the strength of the section bar 11 and the corner fitting 12 at the butt joint portion. The rib 116 is arranged at a position adjacent to the LED lamp strip, and the middle part of the length direction (which is consistent with the length direction of the LED lamp strip) of the rib 116 is exposed in the surrounding environment, so that the contact area between the sectional material 11 and air is increased, the heat exchange efficiency is improved, the heat dissipation of the LED flat lamp is facilitated, and the service life is prolonged.

In order to simplify the structure of the profile 11 and facilitate the processing, in one embodiment, as shown in fig. 3, a limiting step 117 is provided at a communication portion between the lamp groove 114 and the clamping groove 115 to limit the LED strip in the lamp groove 114.

On the cross section in LED lamp area, the both sides in LED lamp area and spacing step 117 counterbalance spacingly, and the light emitting component in LED lamp area is direct along the contact with the side of light guide plate subassembly 2, improves light energy utilization ratio.

Specifically, in one embodiment, the light guide plate assembly 2 includes a reflective plate 21, a light guide plate 22 and a diffusion plate 23 stacked in sequence, a light emitting side of the LED strip faces a side edge of the light guide plate 22, and a side of the diffusion plate 23 facing away from the reflective plate 21 is a light emitting surface of the LED flat lamp. The light emitted by the LED lamp strip is uniformly emitted to the diffusion plate 23 through the light guide plate 22, so that the comfort of a user is improved. Light scattering is further increased by the diffuser plate 23, improving user comfort.

In one embodiment, as shown in fig. 5, the corner fitting includes a body 123, a plug post 121, and a wing 124. The body 123 is provided with a mounting hole 125 penetrating in the thickness direction of the bezel 1. The number of the inserting columns 121 is two, and the two inserting columns are respectively positioned on one side of the body 123, which is butted with the corresponding section bar. The two wing plates 124 are respectively located on the body 123 at the side where the corresponding section bar is butted, and each wing plate 124 is bent to form the second slot 122.

The body 123 is used for filling the gap between two adjacent profiles 11, and the two flanges 124 are used for abutting two adjacent profiles 11. The wing plate 124 is integrally formed with the body 123, and is convenient to manufacture. The wing 124 is bent at the second slot 122 to form a top wall overlying the rib 116 and two side walls that grip the fixed rib 116 from both sides. The mounting holes 125 are used to secure the LED flat panel lamp to a building wall at the installation site.

In order to make the connection between the profile 11 and the corner fitting 12 more secure, in one embodiment, as shown in fig. 4 and 5, two ribs 116 on the outer wall of the first slot 111 are arranged side by side, a limiting slot 118 is arranged between the two ribs 116, two wing plates 124 are provided with limiting holes 126 corresponding to the limiting slot 118, a fastening member (not shown) is installed in the limiting hole 126, and a part of the fastening member extends and is fixed in the limiting slot 118.

After the section bar 11 is inserted into the corner fitting 12, the position of the limiting hole 126 is opposite to the position of the limiting clamping groove 118, and at this time, the rib 116 of the section bar 11 may be pulled out from the second slot 122 of the corner fitting 12 due to looseness, and in order to make the butt joint of the section bar 11 and the corner fitting 12 more firm, a fastener is additionally arranged. The upper half section of the fastener is clamped into the limiting hole 126, and the lower half section of the fastener is clamped into the limiting clamping groove 118, so that the section bar 11 and the corner fitting 12 are limited in the length direction of the section bar 11. In one embodiment, the fasteners are screws.
