About LED (Light Emitting Diode) Technology

LED means Light Emitting Diode. An LED is small electronic device  (semiconductor) that emits light when a current flows through it.

Unless conventional bulbs, Almost all of the energy in an LED radiates within the visible spectrum.

Advantages of using LED technology include:

• High-levels of brightness and intensity
• High-efficiency
• Low-voltage and current requirements
• Low heat
• High reliability (resistant to shock and vibration)
• No UV Rays
• Can be easily controlled and programmed

The Future of Light

Over the past several years, LED technology has advanced by leaps and bounds. In the past, lack of colors and the low intensity made LED’s useful only as indicator lights. As the manufacturing methods and technology have improved, the LED has quickly found itself suitable in many more applications. As this technology advances further and more applications are attained, the light emitting diode will be the light source of choice for virtually all lighting scenarios.

Long Life Reliability

LED’s have a functional lifetime that is far longer than the more traditional lighting technologies. However, contrary to some claims, LED life is finite, and will vary with color and chip make-up. LED’s will degrade over their life span.

An LED can last from 30,000 to 100,000+ hours, almost 50 times longer than most incandescent light sources (2000 hours) or up to 10 times longer than fluorescent sources (10,000 hours).

Long Life:
Realizing rated LED lamp life is dependent on meeting LED manufacturer’s recommendations for:

• operating temperature
• operating voltage & current
• electrical junction temperature
• thermal dissipation
