About Electroluminescent (EL) Lighting:
EL Light is created when light emitting phosphor crystals are excited by being exposed to an electric current.
|
|
| _ |
 Low energy consumption (Most efficient light source on Earth!)
|
There are no No hazardous materials and is landfill friendly! |
Extremely Flexible |
Cool to the touch, virtually no heat emission |
Highly visible in darkness, smoke, fog etc. versus point-sources of light |
Paper thin |
Can be seen at greater distances than point source lamps in the dark |
Maintenance Free |
Easy to look at, pleasing to the eye |
No filament to break – never fails to light! |
Does not impair night vision |
| |
|
| Photometrics – Measuring Light: |
| |
|
| Luminance is measured in |
| ____Foot-Lamberts or Candelas per meter squared |
| ____1 Foot-Lambert = 3.426 Candelas/m 2 |
| Luminance measures how easy something is to see |
| ____i.e. Exit Signage, A Full Moon, FLATLITE |
| Illuminance is measured in |
| ____Foot-Candles and Lux |
| Foot-Candles measures how much light there is to see by |
| ____i.e. Emergency Lights (level on the floor), The Sun (daytime) |
| EL is a light source intended to be seen, not to see by |
| |
|
| EL Phosphor Facts: |
|
| |
|
| All electroluminescent phosphors emit light when placed in a field of __alternating current |
The higher the voltage and / or frequency, the brighter the light, but the __shorter the life- Color also changes with Frequency |
All EL Phosphors will slowly lose their ability to produce light over their __operating life – they are not affected by turning on and off |
| Un-encapsulated EL Phosphors are highly vulnerable to damage due to __moisture :FLATLITE utilizes encapsulated phosphors |
| Phosphors are manufactured to give off specific colors when energized |
__Blue and green phosphors tend to have longest life and brightness |
| |
|
| EL Phosphor Encapsulation: |
|
| |
| EL Lamps use either encapsulated or un-encapsulated phosphors |
| |
Encapsulated phosphors have each microscopic phosphor particle __surrounded by a glass-like protector |
This acts as a moisture barrier to the phosphor, providing reasonable __protection from moisture - Manufacturing and lamination offer additional __protection |
| Limited worldwide suppliers of encapsulated phosphors |
| FLAT LITE ® uses encapsulated phosphors |
| |
|
| Colors: |
|
| |
| FLAT LITE ® is manufactured using 2 basic phosphor formulas. One __appears pink when off and white when energized, and the other __appears white when off and green/blue when energized. |
| Nu-World Distribution makes available 6 color overlays – yellow, orange, __red, green, magenta, blue. |
| Unlimited numbers of overlays available from third party suppliers can be __added per installation |
