LED Lighting - Why?

LED is solid-state lamp that uses light-emitting diodes (LEDs) as the source of light. It is a Semiconductor devices like Diode. It is safe to environment and it has a very long service life.


Traditional Incandescent Bulb generate light by passing electric current through a resistive filament, thereby heating the filament to a very high temperature so that it glows and emits visible light. Incandescent light is highly inefficient, as about 98% of the energy input is emitted as heat. A 100 W light bulb emits about 1,700 lumens, about 17 lumens/W. Incandescent lamps are relatively inexpensive to make. The typical lifespan of an AC incandescent lamp is around 1,000 hours.They work well with dimmers. Most older light fixtures are designed for the size and shape of these traditional bulbs.


Fluorescent tube or lamps work by passing electricity through mercury vapor, which in turn emits ultraviolet light. The ultraviolet light is then absorbed by a phosphor coating inside the lamp, causing it to glow, or fluoresce. While the heat generated by a fluorescent lamp is much less than its incandescent counterpart, energy is still lost in generating the ultraviolet light and converting this light into visible light. If the lamp breaks, exposure to mercury can occur.

Compare on these 3 different lighting technology, very significantly that LED is the most efficient technology in delivering lighting as Incandescent and Fluorescent lighting is wasting most of the energy as heat.


LED Lighting REDUCE the usage on electrical energy to produce light.


And with lesser HEAT produced by LED Lighting, electric energy needed on our home or office Air Conditioner also REDUCED.
