Session: A Lighting Designers’ LED Wish List

2012 DOE | Solid State Lighting R+D Workshop

Lighting defines a space, sets a mood, and enhances architectural features, engages the senses. It’s experiential

Lighting encourages direction, motivation, increased productivity and creates a sense of well-being.

Light crafts a luminous environment that is both aesthetically and performance oriented.

Light Form Fusion

Lighting can influence the experience

Technology can support lighting in creating that experience

Lighting Designer’s LED WISH LIST

Key areas to address

Color

Controllability

Efficiency

Comprehensive Reported Criteria

Lighting Designer’s LED WISH LIST

Produce LED’s as close to black body curve as possible (no greater than +/- 0.006 Duv)

Color

Color metrics that are meaningful to LED application to understand visual experience

Dynamic color dimming to replicate color shift of incandescent

• CRI including R9 Value • CQS – Color Quality Scale – Adopt • CCT – Correlated Color Temperature • Duv - Max +/- 0.006 (Delta off black body curve) • Delta u’ v’ - Max + 0.04 (Color shift over time)

Lighting Designer’s LED WISH LIST

Increase efficiency in LED directional sources for comparable alternative to PAR30, PAR38 and PAR56

Increased Efficiency

Tubular LED with color range and better efficiency to exceed existing fluorescent cost, life, watts per linear foot

Narrower beam equal to AR111 (10 degrees)

Lighting Designer’s LED WISH LIST

Controllability

Smooth dimming to off without “clicks”

Built in intelligence – occupancy sensor in the lamp, end of useful life signal

LED output adjusts light output/power consumption - as LED efficiency improves, we can replace modules in future with equal light output but less energy consumption

Lighting Designer’s LED WISH LIST

Manufacturer Report (Must include) • Lamp Current • Input Wattage & Power Factor or Volt Amps (preferred) • Lumen Output • Efficacy • CRI including R9 Value • CQS – Color Quality Scale metrics • CCT – Correlated Color Temperature • Duv - Max +/- 0.006 (Delta off black body curve extremes) • Delta u’ v’ - Max + 0.04 (Color shift over time)

Standardized Reported Criteria

Lighting Designer’s LED WISH LIST

• Parking Garage Luminaire with uplight (relocate heat sink)

• Customizable optics for Roadway fixtures for house side shield to achieve LEED point

• Fixture housings for harsh environments, Natatorium, Marine

• Flood light with equivalents optics, wattage, output to compete w CMHT9 technology

• Five to seven year warranties

• Optical accessories for glare control – roadway luminaires

• Line voltage LED fixtures
