Incandescent lamps rely on tungsten wires to emit light, but the source of this light actually comes from the heating of the tungsten wires. Just like how a red iron wire naturally produces a certain level of brightness, from a physical perspective, this is the process of converting electrical energy into thermal energy, causing the electrical energy to split and the amount of converted light energy to decrease, resulting in a decrease in the amount of light emitted. On LED lights, it is very light. It should be noted that LED is essentially a light-emitting diode. When electricity is applied to it, it will cause collisions between electrons and holes, forming photons. Ultimately, the light will also burst out in the form of photons. After receiving electrical energy, the vast majority of LED lights are converted into light energy, which is highly efficient. In addition, the mode of LED lights using photons as light sources also makes them appear brighter.
