What is an LED?
Early LED technology
Power limited to 1/8 watt maximum
Light Emitted Forward
Plastic encapsulated
Reflector
Anode Lead
Advanced LED Technology
Power up to 5W
Efficiency up to 150 lumen per Watt (*)
Light Emitted Forward
Reflector Cup
(*) Demonstrated efficiency in the lab by Nichia 2007.
LED’s offer a wide range of white light
• Warm White
– 3200 - 3500K nominal color temperature–
optimal CCT for general lighting
– Typical CRI > 85
– Efficiency of >65 lumen/Watt
• Daylight White
– 4000-5600K nominal color temperature
– Flux levels >85 lumen/Watt
– CRI >75
– 6500-9000K color temperature
– Flux levels >100 lumen/Watt
– CRI <60
