The external control LED guardrail tube finds out the direction of the signal. Generally, the male head is the signal input, and the female head is the signal output; then install it according to the signal direction diagram provided by the manufacturer. Effort and money. The other is the power supply installation: if it is a DC (direct current) LED digital tube, you must pay attention. Under normal circumstances: the two-core small plug is the power supply, the red is the positive pole, and the blue line is the negative pole; be sure to check first after installation Circuit, confirm OK, and then power on; otherwise, the LED digital tube will be burned out, which will seriously affect the project acceptance.

           LED strip installation

            LED light strips include LED rainbow tubes, LED flexible neon lights, etc. When installing, try not to remove all the light strips from the reel, and then pull them all over the building for installation; because if the force is too strong, it will lead to the light strip. The main line is broken, causing irreparable damage to the light strip; if there is a non-lighting unit in the middle, you can use a blade to cut off the non-lighting unit, and then connect it with an intermediate connector.

When using outdoors, the docking plug and tail plug should be waterproof.

          In addition: pay attention to the negative sum of power when using wires; when the power consumption of the project is not large, the main wire of the national standard 4 square millimeters is used, and the route from the transformer to the lamp tube is used 2.5 square millimeters of wire. The signal line should use the super five network cable as much as possible.
