A typical car light consists of a tightly coiled thin tungsten filament in a bulb filled with an inert gas. When an electric current is passed through the tungsten filament, it burns and emits white-hot light. Under the action of very high temperature , the tungsten atoms in the tungsten filament are in a state of evaporation. Over time, more and more tungsten atoms will evaporate, and the tungsten filament will become thinner and thinner, and eventually burn out, and the tungsten atoms will be deposited on the relatively cold bulb glass. On, there will be a layer of shadow over time, blocking the light, the brightness of the lamp will be weakened and aging, affecting driving safety.
