The conductive sleeve is detachably connected to the second positive conductive column and the second negative conductive column. When the whole lamp is used alone, the conductive sleeve can be removed from the conductive column to facilitate the installation of the whole lamp.

[0015] The conductive sleeve has a notch on its side, so that the longitudinal cross-section of the conductive sleeve is "C" shaped at various locations, and the first positive conductive column, the first negative conductive column, the second positive conductive column and the second negative conductive column are interference fit with the inner wall of the conductive sleeve.

The shelf frame supports the installation of the sealing plate; the pad provides support for the installation of the reflective paper; the light projected onto the reflective paper through the light guide plate can be reflected by the reflective paper, so that the light can also be effectively projected outward through the light-transmitting cover, thereby realizing the effective utilization of energy and avoiding energy waste; the light emitted by the LED lamp beads is projected onto the first light-transmitting plate under the action of the light guide plate, and then projected onto the light-transmitting cover through the first light-transmitting plate, and then projected to the outside through the light-transmitting cover, thereby realizing the uniformity of light output from the light-transmitting cover; by closely fitting the second light-transmitting plate on the first light-transmitting plate, the uniformity of light output is further realized, and at the same time, the second light-transmitting plate is covered on the square frame, and the light-transmitting cover is covered on the second light-transmitting plate, so that the light can be projected to the edge of the light-transmitting cover through the second light-transmitting plate, thereby realizing that the entire upper surface of the light-transmitting cover can emit uniform light.

[0020] The light-transmitting cover is a PC diffusion cover, and the PC diffusion cover includes a horizontally arranged diffusion plane, and the second light-transmitting plate is installed on the square frame by pressing the diffusion plane, so that the upper end surface of the second light-transmitting plate is installed in a close fit with the inner surface of the diffusion plane, and the four sides of the diffusion plane are provided with vertical installation walls, and the four installation walls are connected end to end to form an installation frame that matches the square frame, and the installation frame is provided with a plurality of positioning hooks, and the lower side of the square frame is surrounded by a concave positioning groove, and the PC diffusion cover is installed on the square frame by the positioning hooks hooked in the positioning grooves. The light-transmitting cover has a simple structure, and the stable installation of the PC diffusion cover and the square frame is achieved by the cooperation of the positioning hooks and the positioning grooves, and it is easy to disassemble and assemble.

[0021] The backing plate is an acrylic backing plate. The acrylic plate has the advantages of long service life, light weight, high recyclability, etc. It can effectively increase the service life of the whole lamp, reduce the weight of the whole lamp, and is environmentally friendly.

[0022] The first light-transmitting plate is arranged between the two light source plates, and the two outer end surfaces of the first light-transmitting plate are respectively fitted with the inner end surfaces of the two light source plates to cover the LED lamp beads. The two outer end surfaces of the first light-transmitting plate are respectively fitted with the inner end surfaces of the two light source plates to cover the LED lamp beads, ensuring that all light emitted by the LED lamp beads can be projected to the second light-transmitting plate through the first light-transmitting plate, and then projected to the PC diffusion cover, ensuring the uniformity of all light output.

[0023] The lower surface of the first light-transmitting plate is sprayed with white paint at a position facing the LED lamp beads to form a semi-transmitting area, and the width of the semi-transmitting area is greater than the straight-line distance between the inner side wall of the light source plate and the side of the light guide plate facing it. Through the semi-transmitting area, the brightness of the light transmitted through the area is basically consistent with the brightness of the light guided through the light guide plate, so as to achieve uniformity of the overall light output.

[0024] The first light-transmitting plate and the second light-transmitting plate are both transparent acrylic plates. The transparent acrylic plate has good light transmittance, which can reach more than 92%, and the required light intensity is relatively small, which saves electricity; at the same time, the acrylic plate has the advantages of long service life, light weight, high recyclability, etc., which can effectively increase the service life of the whole lamp, reduce the weight of the whole lamp, and save energy and protect the environment.

[0025] Compared with the prior art, the advantages of the present invention are: through the electrical connection plugs and the electrical connection sockets matched with the electrical connection plugs arranged opposite to each other on the two sides of the square frame, the positive pole of the LED light-emitting device in the lamp is connected to the positive pole of the electrical connection plug, the negative pole of the LED light-emitting device is connected to the negative pole of the electrical connection plug, the positive pole of the electrical connection plug is connected to the positive pole of the electrical connection socket, and the negative pole of the electrical connection plug is connected to the negative pole of the electrical connection socket. Not only can the independent installation and use of the whole lamp be realized, but also a safe and convenient series installation between multiple lamps of the structure can be realized through the plug-in cooperation between the matched electrical connection plugs and the electrical connection sockets. The structure is simple and the use is safe and convenient. BRIEF DESCRIPTION OF THE DRAWINGS
