Why are incandescent light Bob's considered to be low efficiency than LED light bulbs
Incandescent light bulbs are considered to be low efficiency compared to LED light bulbs for several reasons:
1. Incandescent bulbs produce light by heating a filament inside the bulb, which results in a lot of wasted energy in the form of heat. This means that a significant portion of the energy used by an incandescent bulb is not converted into light, making them less efficient.
2. LED bulbs produce light by passing an electrical current through a semiconductor diode, which converts energy into light much more efficiently. This method of producing light is much more energy-efficient compared to the heating process used by incandescent bulbs.
3. LED bulbs are also more efficient at producing light in specific directions, meaning they can be designed to direct light where it is needed without wasting energy on producing light in all directions like incandescent bulbs.
4. Because of their lower energy efficiency, incandescent bulbs have a shorter lifespan compared to LED bulbs, meaning they need to be replaced more frequently, leading to higher overall energy costs in the long run.
