[0002] LED light panels are mainly composed of LED lamp beads, substrates, light guide plates, shells and other parts. The LED lamp beads emit light, which is conducted through the substrate and evenly distributed on the light guide plate to form a soft and uniform lighting effect. At present, LED light panels usually use aluminum heat sink fins as part of the shell to increase the heat dissipation area, and the existing aluminum heat sink fin shell and LED lampshade are mostly connected in a snap-fit ​​form. However, if the LED light panel is damaged and needs to be repaired, the aluminum heat sink fin shell and the LED lampshade will be difficult to separate in a snap-fit ​​form. If the operation is improper, the buckle will be damaged and cannot be used. Therefore, a heat dissipation connection structure of the LED light panel is proposed. Utility Model Content

[0036] The first fixing plate 53 is kept vertically with one of the vertical slots.

[0037] The lampshade 3 is sleeved on the bottom of the fixing frame 1 and pushed upward, the lug 4 contacts with the bottom of the abutment block 63, and the abutment block 63 and the projection 66 are pushed upward to move up and compress the spring piece 62. During the upward movement of the projection 66, the transmission column 51 and the first fixing plate 53 are driven to rotate ninety degrees through the arc groove in the guide groove 52. At this time, the projection 66 is located at the top of the vertical groove of the guide groove 52, and one end of the first fixing plate 53 is located at the bottom of the lug 4.

At the same time, the abutment block 63 always abuts against the top of the lug 4 under the action of the spring sheet 62, thereby improving the stability of the connection between the lampshade 3 and the fixing frame 1.

[0045] The working principle and use process of this utility model:

[0046] The lampshade 3 is sleeved on the bottom of the fixing frame 1, and the lampshade 3 is pushed upward, the lug 4 contacts the bottom of the abutment block 63, and pushes the abutment block 63 and the projection 66 upward to compress the spring 62. During the upward movement of the projection 66, the transmission column 51 and the first fixing plate 53 are driven to rotate 90 degrees through the arc groove in the guide groove 52. At this time, the projection 66 is located at the top of the vertical groove of the guide groove 52, and one end of the first fixing plate 53 is located at the bottom of the lug 4.
