LED Market Exploding
Sales of LED’s will
grow 40% in 2008 and
reach $1.6 billion by
2012.”
“By 2011, the total
market for LED’s in
lighting is forecast to
grow at a CAGR of
36.9%to reach
approximately $1
billion.”
“LED’s will save
Americans $280 billion
in energy costs over the
next 20 years and the
technology will make
up 70% of the market
by the end of that
period.”

What is an LED?
• A small semiconductor that emits photons when
electricity is applied
• Comparison to bulbs
• LED produces up to 100 lumens per watt; use
1/10 power vs incandescent bulbs

What Types of Outdoor Commercial Lighting
Can Use LED Light Engines?
“Wall pack” lights placed on the sides of buildings and warehouses
Parking lot “Pole Lighting”
Spot lighting
Walkway “Bollard” Lighting
Near Future: Street lights

•Aluminum Casting with Borosilicate

•150 to 250W Metal Halide Bulb

•Bulb requires replacement every 1-3
years
This and other wallpack lights are industry
standards for outdoor lighting
10
Why Use LED Lighting Now?
•
•
•
•
LED’s use far less energy; up to 75% less
LED’s last longer, up to 30 times longer
LED’s cost less to use over their lifetime
LED’s are now the most energy efficient lighting source
available. Wall Street Journal, Sept 2008
• LED reliability is vastly superior to any current lighting
technology
11
Reasons to Retrofit Your Lighting with LED’s
• Fluorescent light sources are energy efficient but do not
last long, plus contain mercury and other toxic substances
• Metal Halide requires frequent re-lamping
• Sodium (LPS) is long-lasting, but the light color is awful
• HPS has somewhat better color rendering, but still falls
short
• Utility rates are going up (PG&E is up 6% near term) and
will only go higher

Advantage to Building Owners
•
40% to 75% electric power savings, depending on application
•
No maintenance (greater cost savings than the cost of energy saved)
•
Less potential for Liability from failed lights (Reliability existing technology
cannot match)
•
Depending on the light size and type, the local cost of power, labor rates, etc.
the user can save as much as $1200 per light over the 14-yr life of the LED’s.
For 1,000 lights, that is $1.2M in savings, at today’s costs*
•
Capital cost payback in less than 3 years typically
•
5 year warranty
*
Which are certain to rise

Lifetime/Lumen Maintenance of the
Green Machine Light Engine
LED Manufacturer and Type
The high-brightness white LED’s we use in the Green Machine Light Engine are the
Philips Luxeon Rebel series.
We selected the Rebel device for the following reasons:
 High Lumen/Watt (efficiency) performance
 Excellent package design with low thermal resistance
 Availability of good reliability data with supporting design information
 Philip’s commitment to stand behind the product
The following pdf document is an excerpt from the Luxeon Rebel series reliability report,
which contains the manufacturer’s reliability information for the devices we are using.
Lumen maintenance reliability as a function of
device junction temperature:
B50 / L70
• B50, L70 means that 50% of a population of devices will output
70% of the Lumens as when new. The more current applied to
drive the LED, the more heat is generated. We drive the Rebel
LED at 700 mA, which is the red curve in the above illustration.
Referring to the illustration, note that the 60,000 hr Lumen
maintenance number applies to devices where the diode
junction temperature is held to about 135°C or below. This is
done by both electrical driver parameters and careful thermal
management in the system mechanical design.
• Our standard is to hold LED junction temperatures below
110°C, done by the use of special metal-clad circuit boards, the
spacing of the LEDs on the board, plus good heat sink design
for the assembly, and finally driving the LEDs at less than
maximum rated current.
Why Maintain Such a Low Junction
Temperature?
While according to the device specifications we could drive the LED’s
harder (up to 1A), LED efficiency drops substantially after a certain
point. While you can get more Lumens output at higher drive currents,
Lumens output per Watt input drops off substantially. So there are
other benefits to keeping the LED’s relatively cool. The driver
electronics would also be stressed at higher currents, and we prefer
to maintain good margins in all parts of the design. While there is no
published data on how much longer the LED’s could maintain 70% of
their initial Lumen output if run substantially cooler than 135°C,
experience suggests possibly both B50 and L70 could be enhanced..
System Reliability
GMLE’s designs incorporate other system practices that ensure
reliability, beyond what most other vendors have even considered. We
understand that the reliability of the system is what matters, not just
the LED light engine.
