Technical Field

[0001] The invention belongs to the technical field, and in particular relates to a panel light back cover with a built-in power supply. Background Art

[0002] The existing side-emitting panel lights on the market, during the installation process, first install the LED light bar on the side of the frame, then stack the rear cover, reflector, light guide plate, and diffuser plate on the frame and fix them, and finally install the LED power driver on the outer surface of the cover, and align the light source of the LED light bar with the light guide plate to achieve lighting; due to the compact structure of the side-emitting panel lights, the LED power driver can only be installed externally;

[0003] The back cover of the backlit panel light has more space inside, and the LED light strip can be installed on the back cover, such as a new type of backlit panel light in CN201721884879.6, but its LED power driver can only be external;

[0004] The external LED power driver for backlit panel lights has the following shortcomings: 1. The panel lights and LED power drivers sold by the manufacturer need to be packaged and sold separately, which increases packaging time and cost; 2. When installing the LED power driver, if there is no reserved installation hole on the back cover, it is necessary to punch holes separately, which increases the installation steps, and during the drilling process, you must pay attention to the position of the built-in LED light strip and not damage the LED light strip; 3. The external LED power driver does not have any protection and is easily damaged by dust. Summary of the invention

[0027] The present invention will be further described below with reference to specific embodiments in conjunction with the accompanying drawings;

[0028] The present embodiment provides a panel light back cover 01 with a built-in power supply, comprising the back cover 01, a power supply housing 02 is installed on the inner surface of the top plate of the back cover 01; the power supply housing 02 is box-shaped with a wall opening, an LED power driver is installed in the power supply housing 02, the outer surfaces of both side walls of the power supply housing 02 are recessed to form a step-shaped slide 020, and the slide 020 is injection molded by the power supply housing 02; two card blocks 010 with a "7"-shaped cross-section protrude from the inner surface of the top plate of the back cover 01, the card blocks 010 are integrally formed with the back cover 01, and the heads of the two card blocks 010 are arranged facing each other to form a first card slot 011; the power supply housing 02 is inserted into the first card slot 011 and the slide 020 is pressed by the head of the card block 010 to be clamped and fixed. The LED power driver of the present invention is installed on the back cover 01 through the power housing 02. The power housing 02 and the card slot are connected in a plug-in manner, which is a detachable structure. It not only realizes the built-in LED driver power supply, but also is different from the built-in LED power driver fixed by screws. The power housing 02 is detachable, which is convenient for later disassembly and replacement;

[0029] Usage process: The LED power driver is installed in the power housing 02, and the two side guides 020 of the power housing 02 are then slid into the first card slot 011, and the card block 010 fixes the power housing 02 to realize the internal installation of the LED power driver;

[0030] Furthermore, the inner surfaces of the two side walls of the power supply housing 02 are protruded with first male buckles 021 with a triangular cross section, and the LED power supply driver is buckled into the power supply housing 02 through the first male buckle 021 to form a buckle fixation; the LED power supply driver is installed in the power supply housing 02 by the buckle method, which is convenient for disassembly and assembly;

[0031] Furthermore, another card block 010 is included, and the three card blocks 010 are connected to form a triangle and two of the card blocks 010 are on the same straight line; the three card blocks 010 are arranged in a triangle, which can clamp the power supply housing 02 more firmly and not easily fall off;

[0032] Furthermore, it also includes a stopper 012; a rectangular stopper 012 protrudes from the inner surface of the top plate of the rear cover 01, and the stopper 012 is located between the side plate of the rear cover 01 and the block 010 to block the power supply housing 02; the stopper 012 plays a limiting role to prevent the power supply housing 02 from being pushed in too much. With the stopper 012, people only need to push the power supply housing 02 to the position of the stopper 012, which is convenient for operation;

[0033] Furthermore, the connecting edge of the top plate and the side plate of the rear cover 01 is recessed to form a mounting pit 013, and a first toothed card 014 is provided inside the mounting pit 013. The top upper surface of the first toothed card 014 is toothed and wavy, and both sides of the first toothed card 014 protrude connecting columns 015 with a hollow center. A first through hole 016 penetrating the rear cover 01 is provided on the side wall of the mounting pit 013, and the first through hole 016 is used for the wires on the LED power driver to pass through; it also includes a wire pressing block 03; two second through holes 030 are provided on the top of the wire pressing block 03, and screws pass through the second through holes to fix the wire pressing block in the mounting pit; two second through holes 030 protrude between the two second through holes Two toothed cards 031, the bottom lower surface of the second toothed card 031 is toothed and wavy, and the first toothed card 014 is located between the two second toothed cards 031; the first toothed card 014 and the second toothed card 031 are used to clamp and fix the wire on the LED power driver; the first toothed card 014 cooperates with the second toothed card to clamp the guide on the LED power driver and pass it through the second through hole 030, and the screw passes through to fix the wire pressing block 03 in the installation pit 013, which not only plays the role of fixing the wire, but also pulls and fixes the LED power driver relative to it, and plays a double protection under the action of the power shell 02, so that the LED power driver is less likely to fall;

[0034] Furthermore, a support plate 017 protrudes from the outside of the installation pit 013, and a second slot 0170 is provided on the top of the support plate 017. The second slot 0170 is used to place the wire driven by the LED power supply; the second slot 0170 is used to clamp the wire to prevent the wire from being tangled randomly;

[0035] Furthermore, a triangular marking pit 022 is provided on the top surface of the side wall of the power supply housing 02; the triangular marking pit 022 serves as a mark to guide people to insert the power supply housing 02 into the first card slot 011 in the direction of the arrow.

[0036] Furthermore, the outer surface of the top plate of the rear cover 01 is concave to form a first concave pit 018; the first concave pit 018 is used to stick a note, and the note stuck on the top outer surface of the rear cover 01 will not have a convex visual sense;

[0037] A panel light has the above-mentioned back cover 01, and also includes an aluminum frame and a diffusion plate. The aluminum frame is welded by four profiles, and the diffusion plate is pasted on the aluminum frame. Then the aluminum frame and the back cover 01 are pasted to complete the assembly. The back cover 01 is made of ABS plastic, and 4 light strips are pasted on the inner surface of the back cover 01. Then, wires are connected to the LED power drive, and the power input line is pressed with a pressure block. Then, glue is applied on the aluminum frame to stick the back cover 01 to achieve a waterproof and sealing effect.
