What is LED?
A light source that is created by a Light Emitting Diode (LED) which is a semiconductor device that emits light when an electric current is passed through it.
For decades, LEDs have been used as indicator lights on myriad products; however, starting in the 2000s, they began to replace incandescent, halogen and fluorescent bulbs. LEDs draw considerably less power and are up to 80% more efficient.
LEDs use much less energy than incandescent bulbs because diode light is much more efficient, power-wise, than filament light. LED bulbs use more than 75% less energy than incandescent lighting.
It's called solid-state lighting because unlike incandescent and fluorescent lighting technologies, there are no gases involved in LEDs. Instead, energy is passed through a semiconductor (usually a solid chemical element or compound that can conduct electricity), lighting up the LED light bulb.
Difference Between a LED Bulb and a Regular Lamp?
LED light bulbs use the light-emitting diode to produce light when negatively charged semiconductors are applied voltage, hence causing electrons to combine which leads to a unit of light. On the other hand, regular bulbs generate light when electric current flows through the heating of a tungsten filament.
Advantages of LED Bulbs
- Long life. The components of an LED and the way that they generate light significantly extend the lifespan of these bulbs.
- Energy efficiency.
- High brightness and intensity.
- Exceptional color range.
- Low radiated heat.
- Reliability.
- Instantaneous illumination.
- Directional lighting.
