When installing LED Downlights, maybe we are always confused should we distinguish the live wire and neutral wire, firstly, we need to know what is a live wire and a neutral wire.
Understand the live wires and neutral wires of LED downlights
Under normal circumstances, the standard wire usage habits: Red and brown wires are live wires, referred to as L. Blue wires are neutral, referred to as N.
Why LED lamp wiring does not distinguish between neutral and live wires?
LED lamps are DC appliances that need to be converted from AC power to DC power to work properly. Therefore, the circuit of LED lamps must contain a rectifier circuit to convert AC power to DC power. In the rectifier circuit, the current will only flow in one direction, so there is no positive and negative distinction in the circuit of LED lamps; that is, there is no distinction between live wires and neutral wires.
Safety specifications and operating requirements
Although the LED lamp itself does not distinguish between live wires and neutral wires, in actual circuit design, for safety reasons, the switch should usually be connected to the live wire. In this way, when the switch is turned off, the LED lamp will not be charged, and it will be safer when changing the bulb. If the switch is connected to the neutral wire, although the LED lamp will not light up, it will still be charged, which may cause safety problems. Sometimes, some lights are sensitive and may emit a faint light.
In addition, when purchasing LED lights, you should pay attention to checking the relevant inspection certificates and quality assurance of the products to ensure their quality and safety. If the quality of the LED lights you purchase is not good, there may be safety hazards such as short circuits and leakage.
When installing LED lights, you should follow the following safety specifications and operating requirements:
1. Make sure that the circuit is powered off before installation and maintenance.
2. Make sure that the circuit meets national standards and safety specifications.
3. Make sure that the switch in the circuit is connected to the live wire.
4. Make sure that the lines in the circuit are firmly connected, and there should be no looseness or poor contact.
5. Make sure that the insulating materials in the circuit meet national standards and safety specifications.
6. Make sure that the load in the circuit does not exceed the rated power of the LED lamp.
Conclusion
Although the neutral and live wires are not divided when the LED Downlights are wired, in the actual circuit design and installation process, certain safety specifications and operating requirements still need to be followed to ensure the safety and stability of the circuit.
When purchasing LED lights, you should pay attention to checking the relevant inspection certificates and quality assurance of the products to ensure their quality and safety. Only by following safety regulations and operating requirements can we better play the advantages of LED lights and bring more convenience and comfort to our lives.
