  1. THE LED REVOLUTION Is Your Showroom Ready ?

  2. The history of LED’S

  3. 1929 - Soviet patent granted for a “ light relay” • 1961 - Modern LED invented at Texas Instruments • 1962 - Red LED invented - First mass produced “indicator lights” • 1970’s - Used extensively in indicator lights and numerical displays - Increased light output10 X - First colored LED produced

  4. 1980’s - Traffic signals • 1990’s - Exit signs and automotive lamps • late 1990’s - First blue LED with vastly increased light output - RGB becomes practical - mainly used theatrically • 2000 - High brightness white produced using RGB method and phosphor coating method • 2008 - Introduction of wide array of LED lighting products

  5. Colour White

  6. Which makes them good for applications requiring a spot light.

  7. Efficiency: Lumens, Watts, & Efficacy • Lumens:total “light” • Watts:total power • Efficacy:how much light for the power (lumens per watt, LPW) (similar to miles per gallon) _______ Watts

  8. Quantity = Footcandles Quantity = Footcandles • Foot Candles: Light per square foot on a surface • Footcandles are what we measure with a light meter • Different tasks require different levels of Footcandles

  9. Color Rendering...ColorRenderingIndex ( CRI ) How Natural And Normal Do People And Things Appear Under Artificial Light? CRI Scale goes from: 0 - 100, with 100 being the best CRI

  15. Currently few LED’s are consistently available in that warm a colour temperature. 5000K 3000K 4000K

  16. Illumination Levels

  17. Junolightinggroup.com • Online training e.luminance

  18. The advantages of LED’S

  19. Size • Efficiency • Life expectancy • Dimmable • Low temperatures • Toxin free

  20. The challenges of LED’S

  21. Cost • Colour • Directional distribution • Performance • Life expectancy of components • Colour shift • Interface with controls • Replacement parts

  22. The best applications of LED’S
