11. How we Do it cont… - As of 6/1/13

12. LED 101

13. Origin of LEDs • Electroluminescent Discovered in 1907 • First LED Created in 1927 • First Practical Use LED Created in 1962 • Used Indicator Lamps, Alarm Clocks, Scientific • Instruments

14. What is an LED • Light-Emitting Diode: a semiconductor diode that emits light when conducting current and is used in electronic equipment. • Tiny “Chip” comprised of layers of Semi-Conducting Material • Generate light through Electroluminescence

15. Traditional Lighting vs LED • Source Directionality Differences • Traditional light sources emit radiant energy in all directions (OMNI-Directional) • Light Distribution Differences • Near-Point Sources vs Multiple Point-Source Illumination • Lamp Housings vs Individual Optics • Light Generation Differences • Incandescent – Heated Filament • Fluorescent – Gas Discharge/Phosphors • HID – Electric Arc Discharge • All need glass bulb to contain gases/coatings

16. Traditional Lighting vs LED - Example 460 Watt Parking Lot Fixtures 105 Watt LED Fixtures

17. Traditional Lighting vs LED Cont… • Light Trespass • When light strays from intended purpose and becomes a annoyance, • nuisance, municipal code violation, or determent to visual performance • Wasted Light • Glare • Sensation produced by luminance • within the visual field that is greater than • light to which the eye is adapted, in turn • causing discomfort or loss is visibility and • visual performance • Sky Glow • Brightening of night sky as a result of • reflected radiation scattered from the • atmosphere, in the direction of observer.

18. Traditional Lighting vs LED Cont… • Form Factor • Small size and directional light emissions enable low-profile and compact • lighting solutions • Must be carefully engineered (heat dissipation) • Infrared and Ultraviolet Emissions • LED are more efficient at generating light • Incandescent – Infrared radiation accounts for 90% of energy consumed • HID – Require ultraviolet-blocking outer bulb

19. Evaluating LED Lighting

20. Testing and Qualifications • LM-79 • Optics and Light Distribution Capabilities • Standard test method for measuring the photometric properties of SSL • devices, allowing calculation of Luminaire efficacy. • LM-80 • Lifetime Test • Thermal Management • Standard method for measuring lumen • depreciation of LEDs, allowing the calculation • of LED lifetime. • Both tests should be performed DOE approved Testing Laboratories

21. Evaluating LEDs Cont… • Lifetime • Lumen Maintenance • LM-79 – Absolute Testing • Percentage of initial light output produced by a light source at some percentage of rated useful life • Can be difficult when comparing to traditional lighting due to different methods used for testing • L70 • “Rated-Life” term utilized by LED fixtures.

22. Evaluating LEDs • Color • CCT • Correlated Color Temperature • Relative color appearance of • white light source • 2700K-6000K • CRI • Color Rendering Index • Measure of how a light • source renders • colors of objects • “0-100”.” 100 being equal • to actual object color

23. Evaluating LEDs Cont… • Light Output and Light Levels • Light Output • Lumen Output – Amount of light generated by luminaire • CCT Effect • Perception must be considered, but can be difficult to quantify • Foot-candles • Amount of Light that actually falls on a given • surface • Most important measurement for establishing • equivalency between traditional lighting and LEDs, • as well as comparing the effectiveness of various • LED luminaries.

24. Certifications and Listings • Designlights Consortium • LED Fixtures only • Energy Star • LED Lamps and certain fixtures • Non-LED products • Many utility companies that provide rebates will follow the guidelines • provided by either DLC or Energy Star.

25. Benefits of LED Lighting

26. Benefits of LED’s – Energy Reduction Form Factor Example - 458 Watt HID Highbay 143 Watt LED Highbay

27. Benefits of LED’s – Maintenance Reduction • Light Generation Difference • Solid-State vs Gas or Filament • Fixture/Lamp Designed around functionality • Durability • Vibration and ON/Off Cycling Resistance • Lack of adverse heat effects (fusing) • Light Level Maintenance • Light Levels maintained longer • Consistent Light Quality

28. Benefits of LED’s – Visual Performance • Light Levels • Less “Hot Spots” • High average Foot-Candles • Light Quality • CCT and CRI • Perception of “Brightness” and safety • Directional Control • Light Trespass avoidance • Sky Glow avoidance (Dark Sky Compliant)

29. Benefits of LED’s – Controls! • Dimming • Many (not) LED products can be dimmed • Compatibility issues with existing Dimmers • CFL – Limited Dimming Range • HID – No dimming Range • On/Off Cycling and Instant On • LED’s not susceptible to life degradation from ON/Off cycles • Lumen output not affect • No Re-strike time • Control • Wireless control can enable multiple luminaire system wide • controls of on/off and dimming • Compatibly with communication types and existing control • systems

30. Benefits of LED Lighting - Conclusion “It is estimated that switching to LED lighting over the next two decades could save the country $250 billion in energy costs over that period, reduce the electricity consumption for lighting by nearly one half, and avoid 1,800 million metric tons of carbon emission” -Department of Energy Energy Efficiency and Renewable Energy

31. Funding Options • Straight Purchase (COSTARS Approved Vendor) • Phased Approach • Performance Contracting
