  2. 2.  Speaker: Diana Mesh, IES, DLF of HTA Lighting.
  3. 3.  “LEDs Demystified for Interior Designers”  LED terminology and technology explained in simple concise terms to assist designers in selection of lighting fixtures and lamps.
  4. 4. 1. Basic Lighting terms for LEDs explained 2. LED color explained in detail 3. How LEDs work and why this affects your plans 4. How to understand light levels easily 5. LED fixture requirements explained
  5. 5. -you have been warned!
  6. 6. -Let’s take this apart piece by piece
  7. 7.  Color-”atmosphere”- why is it so lacking?  Reading a spec sheet- learning a new language  Wrong light levels- yes you are in the dark  Electrical field issues - not remotely interesting  The Ugly
  8. 8. CHIP ON BOARD AFTER MARKET  When LEDs are integral to the fixture.  Lamps that simply screw in or have a base to work with an existing fixture that is not LED by design
  9. 9. CHIP ON BOARD AFTER MARKET
  10. 10. CHIP ON BOARD AFTER MARKET
  11. 11. CHIP ON BOARD FRONT AND BACK
  12. 12. CHIP ON BOARD INTEGRAL LED
  13. 13. STRIP LIGHTING NOTICE WHITE CIRCUIT BOARDS
  14. 14. FOR EDISON BASE EVEN CANDELABRA
  15. 15. EVEN FOR BI-PIN BASES EVEN FOR FL LAMPS  Even straight lamps
  16. 16. WHAT YOU NEED TO KNOW JUST TO BUY A LAMP!
  17. 17. WHITE LIGHT IS THE ISSUE RAINBOW REVEALS THE SPECTRUM  Note, there is no such thing as a white ray of sunshine. White is the sum of all colors.
  18. 18. WHITE DOESN’T EXIST! REMOTE PHOSPHOR  Blue substrate + coating
  19. 19. Color temperature Does it seem warm or cool?
  20. 20.  Kelvin temperature
  21. 21. Color issues Color Temperature
  22. 22. Color rendition A critical issue for interior lighting
  23. 23. Color rendition Poor CRI will dull colors
  24. 24. POOR CRI HIGH CRI  Less than 80 for interiors Look for 85 to 97
  25. 25. R VALUES YOU WANT R9  CRI numbers didn’t seem to say it all. New metrics had to come into play.
  26. 26. MACADAM ELLIPSE COLOR CONSISTENCY
  27. 27. WHERE WILL YOU FIND IT WHERE YOU WON’T
  28. 28. EXPENSIVE BUT IS IT WORTH IT?  Knock a whole in your budget
  29. 29. The BAD Light distribution of LEDs is different How do you gauge light level? Electrical requirements are different
  30. 30. THEY ARE NOT OMNI DIRECTIONAL, CHIPS ARE FLAT
  31. 31. PENDANT WITH CHIP ON BOARD PENDANT WITH AFTER MARKET  Light may only go downward.. You have to ask
  32. 32. FLAT CHIP TIGHT FILAMENT  Not easy to get tighter than 8 degrees-  Low voltage pin spots a thing of the past?
  33. 33. LUMENS NOT WATTS  32 watt FL lamp= 2800 lumens  40 watt A15 = 415 lumens
  34. 34. LUMENS LUMENS  What you used to know 60 A19 =865 lumens 75 A19 = 1150 lumens 100 A19 = 1710 lumens 150 A21= 2780 lumens
  35. 35. LUMENS CANDELAS  Amount of light versus amount of light in specific direction
  36. 36. LEDS ARE LOW VOLTAGE AND DC CURRENT DRIVERS AND TRANSFORMERS REQUIRED  Generally 24 volt DC but you have to check  Where will they be located?
  37. 37. DRIVERS NEEDED BUT WHERE?
  38. 38. HEAT SINKS LEDS DON’T CREATE HEAT OUT THE FRONT OF THE FIXTURE, BUT THE BACK OF THE CIRCUIT BOARD DOES GET WARM AND A HEAT SINK MUST BE USED AND AIR HAS TO MOVE AROUND THE FIXTURE
  39. 39. DIMMING GET THE INFO  0-10 volt  ELV or even non-dim
  40. 40. DIMMING TO WARM NOW POSSIBLE
  41. 41. READ THE SPEC SHEET READ THE LABELS
  42. 42. Yes, there is plenty of good
  43. 43. ENERGY SAVINGS LUMENS PER WATT KEEPS INCREASING  Lumens per watt is now over 100 in some cases  Incandescent lamps consume about 5 to 6 times the wattage for same amount of light!
  44. 44. THEY DO LAST A LONG TIME CHIP ON BOARD LAST LONGER THAN AFTER MARKET LAMPS  COB = 50,000- 85,000 hours  After Market= 10,000 t0 25,000 hours.. Read the labels!
  45. 45. THEY WILL ALLOW FOR SOPHISTICATED CONTROLS EVEN AFTERMARKET LAMPS DIM WARM  Bi-level switching  Dimming  Remote control  Tuneable white light
  46. 46. THEY HAVE LITTLE OR NO UV ART COLLECTIONS
  47. 47. LESS FADING OR DAMAGE EVEN LIGHTING LARGE PLANES  On fabrics, rugs
  48. 48. THEY CAN BE TINY AND HAVE BIG EFFECTS
  49. 49. THEY CAN CURVE THEY CAN BEND
  50. 50. THEY MAKE NEW FIXTURES POSSIBLE SLEEK DESIGNS ARE POSSIBLE
  51. 51. NEW DESIGNS ARE POSSIBLE THAT REQUIRE NO MAINTENANCE
  52. 52. THEY CAN ADD COLOR INDOORS OR OUT
  53. 53. THEY CAN BE MINIMAL BUT OH SO FUNCTIONAL!
  54. 54. THEY CAN BE SLEEK INCORPORATE INTO ARCHITECTURAL SURFACES  Require little depth and don’t get too hot
  55. 55. THEY CAN BE CONTINOUS LINES OF LIGHT UNLIKE FLUORESCENTS
  56. 56. THEY FIT IN SMALL SPACES WITHOUT DARK SPOTS
  57. 57. THEY CAN START IN COLD WEATHER INSTANT ON!
  58. 58. THEY FIT IN SMALL SPACES ALLOW FOR SMALL FIXTURES
  59. 59. THEY LEAD US THEY SOOTHE US
  60. 60. THEY CAN ADD FUN THEY CAN ADD GLAMOUR
  61. 61. THEY ARE HERE TAKE OUR DOCENT TOUR  LEDucation 10!
  62. 62. Thank you so much for attending!
  63. 63. This concludes The American Institute of Architects Continuing Education Systems Course
