Moore’s Law for LED Lighting

The efficiency and

light output of LED

lighting doubles

every 36 months

CREE Examples

Theoretical limit for LED is 400 lumens/watt!

Myth #2: LEDs Aren’t Bright

• LED fixtures produce a soft voluminous white light that resembles natural daylight

• Less glare

• Fluorescent fixtures produce a green hue

• LED lighting doesn’t attract insects!

CREE LED Lighting

SiC & GaN semiconductor vs GaAs

Integrated design improves reliability

Driver

LED semiconductor

Heat sink

Result: 0.5% reliability for 50,000 - 125,000 hours

Incandescent mean lamp life is 750 hours

50% of CFLs go out after 10,000 hours

50% of Fluorescent tubes go out after 20,000 hours

Expensive

Reduces energy between 55-85%

Reduces annual lighting

maintenance cost between 70-90%
