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 refers to an illumination source that emits light and heat through electrical energy. It was invented by Henry Goebbels in 1854, and Thomas Alva Edison found a more suitable material to develop an incandescent lamp. A light bulb is made based on the principle of the thermal effect of electric current. After the light bulb is connected to the rated voltage, the current passes through the filament and is heated to an incandescent state (above 2000C), generating heat and emitting light, thereby converting electrical energy into internal energy and light energy during operation.
