| Breakthroughs in light-emitting diode (LED) and organic light-emitting diode (OLED) technology are catalyzing development of energy-efficient solid-state lighting (SSL). Once used only for indicator lights, SSL technology is now found in a variety of specialty applications, including automobile brake lights, traffic signals, exit signs, and flashlights. Nowadays white LED devices are created with a record setting efficacy greater than 100 lumens per watt (lm/W) and polymer- based white OLED with a record efficiency of 64 lm/W (small molecule based), the highest known efficiency achieved to date. Research to achieve further technology advances is under way, driving toward development of efficient, full-spectrum, white-light SSL sources that will replace low-efficiency incandescent and fluorescent lamps used for general illumination |
Why Solid-State Lighting? |
|
Solid-state lighting is more and more used in a variety of lighting applications because it offers many benefits, such as: |
|
• |
Long life LEDs can provide 50,000 hours or more of life, which can reduce maintenance costs. In comparison, an incandescent light bulb lasts approximately 1,000 hours. |
• |
Energy savings Commercial white LEDs provide more than 100 lumens per watt, compared to 14-20 lumens per watt for incandescent lighting. LEDs are especially advantageous for colored lighting applications because filters are not needed. |
• |
Better quality light output LEDs have no ultraviolet and infrared radiation. |
• |
Intrinsically safe LED systems are low voltage and have a low temperature (<60C) |
• |
Smaller flexible light fixtures The small size of LEDs makes them useful for lighting tight spaces. |
• |
Robust LEDs have no filament to break and can withstand vibrations. |
