LEDs: The Move to a Digital World J. Chad Stalker III, LC March 21, 2012

Outline • LEDs… – We are beyond just source efficacy (LPW) – Quality of Light starts at the device – LEDs are evolving to the Lighting applications • Luminaires…

– There are solutions for general and specialized lighting applications • Lighting Systems…

– Connectivity and Control are inherent to the solutions being developed

Quality vs. Quality of Light “Quality”, Per Merriam “Quality of Light” Webster…

• IALD, ALA and IES have identified three elements as being integral to • peculiar and essential Quality of Light… character; an inherent feature • degree of excellence; Economic Human superiority in kind • a distinguishing attribute; an acquired skill Architecture

Different Ways to Achieve Freedom From Binning Post Production Sorting

Targeted Kitting

JND > 3 SDCM aka “Just Noticeably Different” • CDM: (source; leading CDM supplier brochure 2010) – A color consistency of 4 SDCM – A consistency of 5 SDM over lifetime • If we stay within 3 MacAdam ellipses, the majority of the people will not see a difference

Color vs. Angle Performance Consistency Throughout the Beam LED w/ Advanced Phosphor System Superior color vs. angle delivers consistent, pure white illumination

Standard LED Inconsistent phosphor conversion results in visual tint in the light beam

LED Luminaire Options • Fixed white light Produces one shade of cool, neutral, or warm white light • Tunable white light Combines cool and warm white LEDs to create a range of shades • Fixed color Produces light of a fixed hue — red, green, blue, amber . . .

• Color-changing (RGB) Combines red, green, and blue LEDs to produce millions of colors and color-changing effects • Multi-spectrum Combines multiple channels of colored and white LEDs to increase the range of colors
