The higher the temperature of the filament, the brighter the light emitted.

Qing buried 2, so called incandescent lamp, from the perspective of energy conversion, when the lamp is shining, a large amount of electrical energy will be converted into heat energy, only a very small part can be converted into useful light energy. The light emitted by electric lamps is panchromatic light, but the proportion of each color is determined by the luminescent substance (tungsten) and temperature. The imbalance in proportions leads to a color cast in the light, so the color of the object is not realistic under incandescent light.
