SSL Fixture Challenges for Lighting Quality and functionality of light Sculpting light distributions in space and time Managing glare Mixing of SSL sources Tuning the spectrum of light Compatibility with controls, artificial intelligence Personalization: digital controls and analog light shaping Differentiation of design Economics (initial & operating costs) Structure of Light Spectral Tuning Controls Market Advantage
The Solution Almost all SSL challenges are impacted or solved by the sculpting of light in space, and not just time:
Sculpting Light in Space. . . . . . Is Powerful
Like Semiconductor: Leveraging Scale Changes Everything Vacuum Tube Transistor Integrated Circuit Incumbent Transition Revolution Filament Tube Light Emitting Diode Integrated System The future of Lighting Leverages Scale of LED Courtesy of Dr. Roland Haitz
Implication #1: The changing physical scale NEW Scale of Light Old Scale of Light LED 100,000 times smaller Fluorescent Lamp LED Progress
Implication #2: The changing luminance scale Limit of visual tolerance Luminance (cd/m2) Office Fixture Limits 100 109 1,000,000 1000 100,000 10,000,000 10,000 100,000,000 T8 Lamp Raw LED LED 10,000+ times brighter Typical source SSL: 10,000X brighter than a typical source
Glare is “Visual Noise” “LEDs have not improved recessed troffers. But they have made them more efficient.” “Even diffuse LED lamps produced a more ‘stripy’ troffer appearance and increased perceived glare, compared to fluorescent lamping.”* *Naomi Miller, et. al, April 2013, “CALIPER 2013 – Exploratory Study: Recessed Troffer Lighting” “LEDs can cause glare, which may negatively impact adoption in some applications.”* SSL: Early Lessons Learned on the Way to Market (DOE 2014) Brighter LEDs only make the glare problem worse.
Simple Substitution = Undifferentiated Solutions Radiation patterns do not disclose glare or other “issues” DOE assessment of direct illumination SSL troffers *Naomi Miller, et. al, April 2013, “CALIPER 2013 – Exploratory Study: Recessed Troffer Lighting”
Light Without Glare A New Approach Introducing a new optical system that efficiently mixes and distributes light in a minimal structure with virtually no glare in fields of view. The Glare Free Filament The filament becomes the fixture
How Light SculptingWorks LEDs coupling Optical Efficiency > 90% mixing extractor Light is well mixed and tightly controlled so that it can be distributed more optimally in the space. reflector flux luminaire flux LEDs
Scale With Control Like a “Directed Linear Lamp” Glare Free Filament: fullcontrol Linear Fluorescent: no control
The Elimination of Glare Eliminates Hot Spots Above Fixture Low Brightness Zone Uniformly Illuminates Ceiling High Brightness Zone Low Brightness Zone Avoids Glare In Environment Moderate Brightness Zone (improves contrast on work surface)
How This Approach Achieves High Efficiency New Solution: Glare Free Filament™ Standard Solution: Conventional LED Luminaire “Lossless” (<1%) Lost in Transport Incoupling (<3%) Lost at Coupling Extraction (<6%) Lost at Extractor Lossy (3 - 15%) Lost Per Reflection Lossy (8 – 18%) Lost Per Diffusion • “Lossless” Total Internal Reflection (TIR) • Light is concentrated and mixed • Light is split and precisely sculpted • Glare is managed • Optical efficiency 90% + • Lossy Diffuse Reflection/Diffusion • Light bounces many times, it is WASTED • Creates semi-lambertian profile • Glare problems • Optical efficiency 65 - 85%
