During installation, one end with the connecting contact rod 9 is inserted into the connecting plate 6 at the front end, and the fixing rod 5 and the connecting plate 6 are fixed together by the screws 7, thereby fixing the connecting plate 6 to the outside of the circuit board 1.

[0021] It should be noted that before use, people need to make the LED lights into light strips, or directly purchase pre-formed light strips and cut them into the required length, and weld connecting contact rods 9 and contact points 11 at the front and rear ends of the LED light strip 4 to transmit external power and signals through the connecting contact rods 9 and contact points 11.

When installing the LED light strip 4, select LED light strips 4 of different lengths according to the required installation position. After selection, insert the connecting contact rod 9 forward into the embedded groove 10 set in the circuit board 1, push it forward until the connecting contact rod 9 passes through the connecting plate 6 at the front end until it is inserted, and then install the connecting plate 6 at the rear end. After the connecting plate 6 is fixed, the contact point 11 at the rear end of the LED light strip 4 contacts the connecting point 12 set in the rear end connecting plate 6.
