  • Questions at any time you like
  • TVS = Transient Voltage SuppressorThe heat in an LED is primarily generated in the junction whereas traditional sources radiate heat outward in all directions.Light is emitted out the front of the LED with virtually no forward heat, so we can provide fixtures that are cool to the touch in the light beam.
  • applications = LEDs can emit infrared, visible or ultraviolet light, and can be used for lighting, to sterilize water and to stimulate the growth of plants“white” = blue LED with a yellow phosphor coating
  • Disclaimer I am not giving you enough information today to be qualified to design and install landscape lighting, please seek in depth training before you attempted this workDo not do this at home it can be dangerous, I am a professional

  • Voltage drop it a factor of wire length and wire load
  • Good way to start retrofitting without having to replace all of the fixtures at onceGives you a wider selection of path or spread lights.
  • Talk about color, optics ver reflectors and beam spread
  • May Jan cost at my house was .1141 cents

    2. 2. • What are the benefits of LED lighting• What is an LED (light emitting diode)• What are the short comings of LED• Design considerations for LED• Cost comparisons of LED and incandescent lighting
    3. 3. By Using LED Landscape Lighting, You Are Doing Your Part To Go Green! Fewer fossil fuels are used in the manufacturing of LED’s than in incandescent lamps.
    4. 4. • Energy $$$$ savings – Uses 1/3 of the energy per lumen compared to incandescent lamps• Maintenance $$$$ savings – No bulbs to be replaced
    5. 5. • Installation cost of the following items is lower – Wire - smaller size and less wire – Power console – fewer transformers and smaller transformers – Labor – less labor designing system wire schemas and less labor to install because of simplified wiring • Disclaimer – The fixtures are generally more expensive than your typical landscape lighting fixture.
    6. 6. • Easier to train your crews on installation techniques• You will have happier customers• You will earn more profits and have a better reputation, less call backs
    7. 7. • Bulbs, Lamps, Arc lamp, Beacon, Candle, Flame, Flare, Illuminator, Lantern, Taper, Torch, etc. What ever you call a Light Bulb LED’s don’t have them!• LED life expectancy is 40,000 hrs. or 18 years at 6 hours on per night
    8. 8. • L – light• E – emitting• D – diode
    9. 9. • Brief history of the LED – 1962 First practical LED (Holonyak, GE) 0.001 lumens – 1960’s Red indicator LEDs – 1970’s 7-segment displays – 1980’s Green LEDs – 1990’s “High brightness” blue (Nakamura, Nichia) 1 lumen – 2000’s Illumination LEDs 100+ lumens 100,000 times brighter than 1962
    10. 10. • Solid State Lighting or SSL – semiconductor die or chip – organically grown crystals – “LED” – packaged device
    11. 11. light emitted forwardHeat Must be conducted away from LED!
    12. 12. • Illumination LED’s in the raw produce a blue light• White light is produced by coating the LED with phosphors of a yellow tone to produce a white light• White light can also be produced using RGB mixing, expensive and complicated
    13. 13. Cosmic Gamma X-Rays UV IR Micro TV RadioRays Rays Waves 400nm 500nm 600nm 700nm
    14. 14. An LED directly converts electricity into light.Apply a forward voltage Vf and current (mA)flows from p to n…
    15. 15. • Are they pitfalls or just new parameters?• New parameters mean CHANGE• Change tends to freak people out!
    16. 16. • Number one Pitfall - The diode does not like high temperatures, end of story.
    17. 17. • High initial price: LEDs are currently more expensive, price per lumen, on an initial capital cost basis, than most conventional lighting technologies. 35w MR16 Accent Light $84.00 MR16 35w bulb $5.00 8.5W LED Accent Light $182.50 LED Retro Lamp $37.00 LED MR16 LED MR16
    18. 18. • Ridged in post installation modifications Foot Candles Beam Width
    19. 19. • High rate of malfunctions in outdoor fixtures.• A lot of manufacturers make bold claims that their bulbs last 50,000 hours yet will only warranty them for 1-2 years.• The color rendering of LED bulbs in a landscape setting can be less than desirable.• Initial overall cost to retrofit is high vs. potential savings. (this gap is narrowing quickly and may be non relevant already)
    20. 20. • Voltage Drop – Each LED manufacturer has a different range for acceptable voltage for lights to work properly – 7 to 18 volts on the extremes – 9 to 15 volts on average
    21. 21. • Wire size – We can use smaller wire size for the same number of fixtures with equivalent light output. – 12AWG wire can handle 192 watts at 12 volts • Equals five 35W incandescent fixtures • Equals fifteen 12.2VA LED fixtures
    22. 22. • Wire lengthT 64ft 175 W MR16T 369ft 12.2VA LED
    23. 23. • You can mix LED and incandescent – LED accent lights with incandescent path lights
    24. 24. HALOGIN LED LED
    25. 25. • No bulbs to change with LED’s
    26. 26. • LED lights tend not to draw insects

    31. 31. • LED is coming to age• It is a green product in its manufacturing, Its life cycle and its energy consumption• Benefits out weigh the pitfalls• Selection, quality and variety of fixtures is increasing rapidly• Cost effective in the long run
    32. 32. • Easy to design and install• Less call backs for repairs from customers• Don’t buy cheep or low cost LED’s they will cost you an arm and a leg when its all said and done.• Retrofit bulbs are worth looking at and will continue to improve with time
