Spot lighting
Walkway “Bollard” Lighting Near Future: Street lights 9 9

10. A Standard WallPack Light
Aluminum Casting with Borosilicate Glass Diffuser
150 to 250W Metal Halide Bulb typical
Bulb requires replacement every 1-3 years
This and other wallpack lights are industry standards for outdoor lighting 10 10

11. 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
With the economy, everyone is trying to save money with current lighting
Current lighting maintenance costs are expensive 11 11

12. 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 12 12

13. Cost of Ownership vs. Metal Halide13 13

14. Cost of Ownership vs. Metal Halide14 14

15. 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

37. 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.

38. Lumen maintenance reliability as a function of device junction temperature:

39. 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.

40. 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.
