THE FUTURE OF LIGHT
Once Limited To Simple Status Indicators, Light Emitting Diodes (leds) Now Play Prominent Roles In
Back Lighting, Panel Indication, Decorative Illumination, Emergency Lighting, Animated Signage,
Etc.... The Emergence Of Leds As A Viable Alternative To Incandescent Lighting Can Be Attributed To
New Manufacturing Technologies, Packaging Innovations And An Increasing Number Of Colors. These
Factors Along With The Growing Awareness Of The Advantages Of Leds (e.g., A Life Span Measured In
Years Not Hours, Vivid Sunlight-visible Colors And Low Power Requirements) Have Engineers, Product
Designers, Purchasing Agents And Component Vendors Viewing Leds In A Whole New Light.
For many
Applications Led Lamps Are Superior To Incandescent Lighting. So Why Is It That In Tens Of Millions
Of Switches, Indicators, Control Panels, Signs, Annunciators, Displays, Decor Lights And Dozens Of
other
Although Advances Made In Led Technology In The Past Few Years Have Dramatically Broadened The
Applications For These Rugged Little Light Sources, It Wasn't That Long Ago That Red Was The Only
"daylight-visible" Colored Led. And That Wasn't The Only Thing Limiting Their Use!
Unlike Incandescent Bulbs That Give Off The Full Spectrum Of Light In A Spherical Pattern, Leds Emit
A Focused Beam Of A Single Wavelength (color) In Only One Direction, In A Variety Of Angles. For
many
Applications, Such As Indicators Or Switch Illuminators, This Is Not A Problem, But It Took The
Development Of Multi-chip Arrays And High-flux Led Chips To Begin To Achieve The Effect Of An
incandescent filament.
Major Advancements In Led Technology Have Taken Place In Recent Years Such As Development Of New
"doping" Technologies That Increase Led Light Output By As Much As 20 Times Over Earlier
Generations, And Allow The Production Of Daylight-visible Leds In Virtually Any Color Of The
Spectrum. In Addition To Red, Yellow, And Amber/orange, Leds Are Now Available In Many Colors From
Leaf Green To Ultra Blue. Even White Light, Long Thought To Be An Impossibility, Is Now Available In
three different shades as a light-emitting diode.
The efficiency of LEDs is most apparent in
Applications Requiring Color. Light From A Typical Incandescent Bulb Must Be Filtered So That Only
Light From A Particular Part Of The Spectrum (e.g., Red, Amber Or Green, Etc...) For Example-is
Visible. While Leds Deliver 100 Percent Of Their Energy As Colored Light, Incandescent Bulbs Waste
90 Percent Or More Of Their Energy In Light Blocked By The Colored Lens Or Filter. Incandescent
Bulbs Also Waste 80 Percent To 90 Percent Of Their Energy On Heat Generation To Reach The
temperature for which (Kelvin scale) they are designed.
The Point Is That What Was Once A Fairly Marginal Light Source Isn't Marginal Any More. In Many
Applications, Leds Exceed The Energy Available From Incandescent Bulbs And Offer Significant
Additional Benefits Making Led Clusters And Lamps As Friendly To The Environment As They Are To The
operating budget.
