Led

Light emitting diodes or what we know as LEDs are basically small bulbs which produce and emit light. LEDs are found in various electrical devices such as watches, blinkers, remote controls, TV indicators, and presently, even LED bulbs and lamps. With the development of LED technology in recent years, light emitting diodes are now commonly used not only as electronic indicators but also as independent light sources in place of the common incandescent bulbs and lamps.One advantage that these light emitting diodes have over the regular incandescent bulbs is that they do not have filaments that burn out so they last much longer. Also, LEDs do not emit heat in the production of light so less energy is wasted in the process of producing illumination.

LED is now considered as one innovative light source which can provide us with many energy advantages. Now, LEDs are independently used as sufficient light sources in different forms. However, its technology is still being currently developed in order to maximize its potentials.

Aside from its ability to last longer due to the lack of filaments, LED lights and lamps are also housed in plastic bulbs which makes them all the more durable. LED is also high on efficacy as it produces less heat than regular filament-based bulbs and light sources. This means that LED has the better ability to produce light without having to waste energy through the release of heat. This high level of efficacy means that LED lights can produce the needed electricity with less energy consumption so it cuts down the demand for more electricity.

LEDs come in various colors of red, blue, green, white, yellow, violet, orange, ultraviolet and infrared. Most of the present LED lamps used in homes now emit white bluish colored light. LEDs are produced in many shapes and sizes depending on their specific function. The typical 5mm LEDs are usually used as indicators in home appliances while the bigger white LEDs are used as lamps. LEDs are still being developed as they are seen to have a huge role in the future of energy and light sources as highly efficient substitutes to both incandescent and fluorescent lights.
