LEDs bring several advantages to the lighting industry, including high efficacy and durability, and, with superior life over other lamp sources, their required maintenance is greatly reduced. This translates into energy savings, maintenance savings, and environmental sustainability. There is also the potential for greater optical control (more controllable source), dimming, instant on/off, and reduced rate of lumen depreciation (potential for long application life).

LEDs began to be used in the lighting industry in the late 1990’s typically in aesthetic, effect, or specialty lighting applications, including architectural highlighting. The use of LED luminaires in applications such as street lighting, area lighting, parking structures, security lighting, and even general lighting for interior spaces is viable today both economically and from an illumination performance standpoint.

Some of the strategies for reducing the cost of LEDs in the future are:

  • Reduction in the production process.
  • Simplification and reduction in the number of components.
  • Introduction of new materials.

LEDs are made of electronic components that need to be packaged together to offer long lasting efficient light sources to the end user. Apart from the LED chip itself which has sapphire and gallium in the semiconductor, the process of packaging with materials like ceramic, rare earth phosphors, silicone, solder and gold wire add to the overall cost. White LEDs require further tests for calibration and standardization.

Yes, LED light is said to be a safer, healthier light. LED’s do not produce any ultraviolet radiation which causes fading in art, fabric, carpeting and other soft goods. With LED lights there is no “buzzing” or “flickering” that many people are sensitive to. Residential, Retail, Commercial and Industrial facilities will immediately benefit from LED lighting.

LEDs have no gases, filaments and no moving parts to fatigue. They provide light through a one-step process that takes place within the diode. There is no glass to break or screwed contacts to loosen.

The term solid state lighting is used because the electronics produce light directly from solid materials in which the electrons are embedded. This is unlike other technologies, for example fluorescent technology, which requires a gaseous discharge medium to initiate production of light.

LEDs are light emitting diodes. These are electronic components that convert electrical energy directly to light through the movement of electrons within the material of the diode. LEDs are important because due to their efficiency and low energy, they are beginning to replace most conventional light sources.
