一. Preparation tools before installation:
1. LED linear light: light source;
2. DC12V drive power supply: convert AC220V mains into safe DC voltage DC12V;
3. Multi-strand copper core flexible wire 0.75mm2: connect the bending light bar;
4, glass glue: fixed line lights.
2, the chimney lighting project DC power wiring installation:
1. L is connected to the "live wire" after passing through the power switch (that is, the wire with electricity is detected by an electric pen);
2. plus V is connected to the red wire of the light bar, -V(COM) is connected to the red and black wire or black wire of the light bar; if the light is not turned on, it will not be damaged.
3. DC power wiring method:
There are two main ways to connect the DC power supply, one is series connection and the other is parallel connection. It is also recommended that the length of the series connection should not exceed 3 meters. If it exceeds 3 meters, please rewire from the DC power supply terminal, otherwise the front light will not be bright enough and the back light will not be enough.
4. Installation preparation:
1. Please try the power supply and each linear light first to make sure that it is not damaged during transportation;
2. Calculate the power of the power supply and determine how many meters of light bars are connected to a power supply. Calculation method: the power of the outdoor linear light per meter X the length of the light bar ÷ 0.8, the calculation method for series and parallel is the same;
3. Determine the wiring scheme to ensure the shortest connecting wires and the simplest wiring;
4. To start the installation, stick the aluminum groove to the inside of the counter. During the installation process, care should be taken to avoid breaking the wire of the linear light.
5. Installation location selection
The waterproof led linear light has a normal heat dissipation function, but if it is in a place with heavy dust, it is easy to cause dust to cover its radiator, which affects the normal heat dissipation of the led hard strip light. Because there are small gaps in the lamp body, these media are easy to enter, which will seriously affect the normal operation of the linear light. If it is unavoidable, it is recommended to take protective measures.
