About Light Emitting Diodes (LEDs)
Light Emitting Diodes (LEDs) are semi conductive devices that convert electrical energy into a discrete color of light: red, green, or blue. White LEDs are also available, though these are actually blue LEDs equipped with special phosphors. LEDs themselves are not new, but only recently have they become bright enough and economical enough for everyday lighting uses.
LEDs are a the world's most advanced illumination technology, delivering beautiful light while consuming a fraction of the energy and lasting up to 20 times longer compared with conventional lighting. As such, they are rapidly replacing traditional incandescent & fluorescent sources of light in a number of applications. The advantages are manifest:
- Ultra energy efficient. LEDs produce far more light per watt consumed than ordinary bulbs. This is primarily because they produce very little heat, resulting in little wasted energy.
- Ultra long life, with usable life of up to 10 years. LEDs never burn out, unlike traditional sources.
- Low maintenance costs, with no gels, filters, lamps or parts to replace.
- Quiet & safe, with no buzzing, humming, or fan/engine distractions; and no UV radiation or harmful pollutants.
- Beauty and control. LEDs are built on semiconductor technology, so they are inherently capable of digital control. This enables an unprecedented amount of customization, control, and programmability of light.
The efficiency benefits and payback periods of LEDs are especially compelling in locations with long working hours such as airports or hospitals. And with increasing concern about climate change and the global impact of energy consumption, never have they been more relevant or needed, whatever the application.
LEDs enable more beautiful architecture, greater visibility for displays or events, more effective corporate branding/imaging, and better functionality where moods are environments largely depend on the light. And all of this in an extraordinarily durable and energy efficient package.
With these compelling benefits, LEDs are poised to fundamentally change how spaces are illuminated in the years to come.
