The maintenance methods for light bulbs mainly include:

1. Do not turn on or off the power of the lights too frequently.

2. Do not let the light bulb shine continuously for too long.

3. Do not connect too many electrical appliances in parallel on the wiring board.

4. Do not plug or unplug the power supply or even turn off the light bulb while the light is on.

5. Do not immediately place the heated light bulb in a cold environment, and vice versa.

A light bulb, also known as an electric bulb or incandescent lamp, is a type of lighting source that emits light and generates heat through electrical energy. Its working principle is based on the thermal effect of current: when the light bulb is connected to the rated voltage, the current passes through the filament and heats it to an incandescent state (temperature above 2000 ° C), causing the filament to heat and emit light, converting electrical energy into internal and light energy.
