What factors contribute to visual comfort? – Light levels – Glare – Color – Uniformity – Visual Interest – How does LED impact?
Visual Comfort
![Page 20: Architectural Ambient Lighting for Office Applications](https://reader036.vdocuments.us/reader036/viewer/2022090905/613c87e8a9aa48668d4a1f2d/html5/thumbnails/20.jpg)
20
Light Levels – Lower levels are visually comforting
• May lack adequate levels to perform certain tasks – Higher levels are more task oriented
• May be less aesthetically pleasing – Choosing the “right” light levels for the
environment is critical to visual comfort • IESNA can be referenced for recommended light levels
for individual tasks
Glare – Direct Glare: bright fixtures and windows in line of sight – Reflected Glare: light sources reflected on glossy surfaces
Visual Comfort
![Page 21: Architectural Ambient Lighting for Office Applications](https://reader036.vdocuments.us/reader036/viewer/2022090905/613c87e8a9aa48668d4a1f2d/html5/thumbnails/21.jpg)
21
Color – Important in differentiation of the perception of
light. – Measured by color temperature and color
rendering (CRI). Higher the CRI, truer the color is perceived
• High CRI = Retail, High end office spaces • Low CRI = Parking garages, lots
Uniformity – Bi-product of efficient lighting – Vertical surface brightness
• Sense of Spaciousness – Less stress on the eye
Visual Comfort
![Page 22: Architectural Ambient Lighting for Office Applications](https://reader036.vdocuments.us/reader036/viewer/2022090905/613c87e8a9aa48668d4a1f2d/html5/thumbnails/22.jpg)
22
Visual Interest – Non-uniform lighting with peripheral emphasis
(accent lighting) – Brings presence to architecturenim
LED Impact – Earlier solutions offered lower delivered lumens
to minimize source brightness and glare – Optimized solutions offer higher LPW while
maintaining visual comfort – Control friendly solutions with minimal cost add
Visual Comfort

• Mixing Type A (main voltage) and B lamps (low voltage) • Shock and fire hazards • Catastrophic failure
o Lamp holder issues with heavier LED lamp • Construction difference of LED vs. LFL creates weight
increase on average of 0.80 lbs. • Areas subject to motion, vibration or impact increases
probability of incident
o Installer “know-how” o Training, staff turnover, retention of legacy knowledge base o Misplaced or missing warning labels
o Future replacement issues • Compatibility • Controls (dimming)
Not “Future Proof” Rewiring Best done by a Certified Electrician
Sockets Not Designed for Added Weight

Installation & Maintenance o Hardware Challenges
• Parts bags provide another level of product management
• Loose Hardware makes installation a challenge
o Pre-Wiring & Assembled Required • Must remove 90% of existing luminaire before Kit install • Assembly and wiring still required for many versions • Creates equal install time vs. fixture
o Thermal Control • Unpredictable thermal impact on lumen output
o Will the Kit Fit? • Complications in fitting 3rd party fixtures (non-universal) • Mounting is vastly different from LFL

Linear LED Key Design Goals
•Platform Approach •Needs to be quickly/easily integrated into existing architectural linear platforms across many brands
•Exceed Fluorescent •If delivered lumens per watt, and color quality does not exceed fluorescent, then no value proposition exists
•Gen I- Existing Platforms •In order for early technology adoption across varied product, must integrate in existing fixture platforms
•“Fluorescent-Like” •Must “behave” like fluorescent. We can not introduce visual discomfort (glare)… regardless of tipping point discussion
•Gen II- “Form follows LED” •Now that we have a viable LED module the sky is the limit.
•Reliability •Quality Testing and Assurance
•Thermal •Electrical/Optical Labs
•Design •UL
