How Bulb Emits Light at Lara Tolmie blog

How Bulb Emits Light. Led bulbs produce light by passing a current through a semiconductor, which emits light energy in the form of photons. This energized mercury vapor emits ultraviolet radiation to the phosphor coating on the inner walls of the bulb, causing it to emit light energy. Hot objects emit light, so the bulb glows. As the current travels through the wires and the filament, the filament heats up to the point where it begins to emit photons, which are small packets of visible light. The production of visible light via thermal radiation is exploited in incandescent light bulbs. The amount of heat produced by. When electricity passes through the filament, it heats up and emits visible light—this is what we see when the bulb is switched on. The higher the temperature, the more intense the glow, and the more white the light. In these bulbs a tungsten filament inside them.
