Why are incandescent light bulbs considered to be lower efficiency than led bulbs?(1point)
Incandescent light bulbs are considered to be lower efficiency than LED bulbs due to the difference in their mechanisms of producing light. Incandescent bulbs work by passing electricity through a filament, which gets extremely hot and emits light as a byproduct of the heat. This process releases a significant amount of energy in the form of heat, making incandescent bulbs inefficient in converting electricity to light.
On the other hand, LED (Light Emitting Diode) bulbs work by passing electricity through a semiconductor material, which emits light directly as a result of the movement of electrons between layers of the material. This process is more efficient as it produces minimal heat, allowing LEDs to convert a higher percentage of electricity into visible light while wasting less energy.
Overall, LED bulbs can convert electricity into light at a much greater efficiency compared to incandescent bulbs, making them more energy-efficient and cost-effective in the long run.
