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.
