4. “LEDs Demystified for Interior Designers”
LED terminology and technology explained in simple
concise terms to assist designers in selection of lighting
fixtures and lamps.
5. 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
8. 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
9. 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
39. 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
44. 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!
45. 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!
46. THEY WILL ALLOW FOR
SOPHISTICATED CONTROLS EVEN AFTERMARKET LAMPS DIM WARM
Bi-level switching
Dimming
Remote control
Tuneable white light
