Brief introduction of led hard strip lamp
Led bar lights are mainly used for lighting and decoration, and are mostly used in hotel lobbies, guest rooms, bars, restaurants and other places. In addition, they are also used in automobile decoration, stage decoration, architectural decoration, advertising decoration, lighting engineering of cinemas and public facilities. It can be seen that led bar lights have played an important role in our lives.
Introduction of installation points of led hard strip lamp
Point 1: Prepare the necessary materials.
The materials to be used are led hard strip lamp, driving power supply, multi-strand copper wire and glass glue. Before installation, the commercial power must be converted into a safe DC voltage that matches the driving power supply voltage.
Point 2: Do a good job of inspection.
First, check and try the power supply and light bar to ensure that it will not be damaged more during transportation. Then, calculate the power of the power supply and determine how many meters of light bars a power supply needs to connect. Then, the best wiring scheme is determined to make the connection line shortest and the wiring work simplest.
The third point: the connection mode of DC power supply
The hard led light bar is connected to the live wire after passing through the power switch, where N is connected to the zero line, +V is connected to the red line of the light bar, and -V is connected to the black line or black red line of the light bar. The reverse connection of +V and -V will not damage the light bar, so don't worry.
The fourth point: the connection mode of DC power supply
There are two connection modes of DC power supply: series connection and parallel connection. It should be noted that if series connection is adopted, it is recommended that the line length should not exceed 3m. If it does exceed 3m, it needs to be reconnected from the DC power supply terminal, otherwise the back of the light bar is not bright enough.
Point 5: Selection of power supply for light bar
Connecting wires also need power, so the power of the light bar cannot be greater than 80% of the rated power of DC power supply, and the light bar of 72 pearl cabinets is per meter 17.2 watts.
Sixth point: Pay attention to the installation environment.
The led lamp tube has normal heat dissipation function. However, if it is located in a dusty place, it is easy to cause dust to cover its radiator and affect the normal heat dissipation of led tubes. In addition, there should be no water vapor, oil fume and other substances in the installation position, because there are tiny gaps in the lamp body itself, and these media can easily enter, which will seriously affect the normal work of the lamp strip. If it is unavoidable, it is recommended to take protective measures.
The installation points of led strip lamp are introduced. I hope you can remember these points and apply them in the actual installation work.
