With the development of society, the use of light bulbs has also undergone different changes. Initially, it may have been to provide convenience for production and life. However, with the progress of society, there have been significant changes in the use of light bulbs, including functional lights for different purposes such as cars, beautifying the environment, and decoration.

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.
