Attention should be paid to the light bulb not being affected by external interference, and it should be beautiful, practical, sturdy, and safe.

1. The connection of wires should be standardized and reasonable.

2. The switch should control the live wire.

3. The screw sleeve of the screw socket can only be connected to the neutral line.

4. The two wires in the lamp holder should be insulated from each other and secured with safety buckles.

A light bulb is a type of lamp that uses a resistor to heat a thin wire (usually tungsten wire in modern times) to incandescence through electricity, in order to emit light. The periphery of the electric bulb is made of glass, which keeps the filament under a vacuum or low-pressure inert gas to prevent oxidation of the filament at high temperatures.
