Beware Glare • Energy codes set minimum efficiencies in
Lumens per Watt • Efficiency - Optical control = Glare
![Page 22: DOE - SSL R&D Summit - Energy.gov · DOE - SSL R&D Summit Changing architecture to incorporate LED lighting . Scott J. Hershman • 10 years Theatrical Lighting Design • 20 years](https://reader034.vdocuments.us/reader034/viewer/2022043010/5f9e976f9538ef613420925a/html5/thumbnails/22.jpg)
Glare Considerations • Smaller source permits more effective optics for a
given size of luminaire • Reflectors (legacy solution) are efficient but not
precise. Good for wide distributions. • Refractors and lenses offer more precise control
at the cost of efficiency • Efficiency should consider lumens reaching the
task, not lumens exiting the fixture.
![Page 23: DOE - SSL R&D Summit - Energy.gov · DOE - SSL R&D Summit Changing architecture to incorporate LED lighting . Scott J. Hershman • 10 years Theatrical Lighting Design • 20 years](https://reader034.vdocuments.us/reader034/viewer/2022043010/5f9e976f9538ef613420925a/html5/thumbnails/23.jpg)
Digital Control • Drivers in each luminaire are an opportunity to
distribute the control system throughout the project. • Control over more than just intensity. Color and color
temperature are now able to be easily addressed. • Existing infrastructure and lighting grid is offers ideal
placement for replacement solutions. • Bidirectional communication and integration of sensors
into the luminaire with minimal impact on fixture cost.

Digital Control Consideration Flicker • When the current stops the LED stops producing
light. Unintended disruptions in the power to the LED can cause visual disturbance.
• Flicker Index • Percent flicker
![Page 25: DOE - SSL R&D Summit - Energy.gov · DOE - SSL R&D Summit Changing architecture to incorporate LED lighting . Scott J. Hershman • 10 years Theatrical Lighting Design • 20 years](https://reader034.vdocuments.us/reader034/viewer/2022043010/5f9e976f9538ef613420925a/html5/thumbnails/25.jpg)
Digital - Control Luminaires can do more than just provide illumination • Bidirectional communication and integration of
sensors into the luminaire with minimal impact on fixture cost.
• Lights can communicate information visually with Color
• Lights can communicate non visually with Lifi

Color Tuning Considerations • Effects on health are still being determined
and debated. • Cost effective systems take a shortcut across
the BBL.
