Trends in Office Lighting Design

19

What factors contribute to visual comfort? – Light levels – Glare – Color – Uniformity – Visual Interest – How does LED impact?

Visual Comfort

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

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

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

Ambient Market Choices

Continue Same Path Fluorescent Systems

– Lowest initial cost still – Operation cost higher to LED – More of the same…

LED Luminaire Higher selection choice Optimized lighting design Lowest labor costs Most reliable

50

LED Retrofit Kits Limited selection Sensible lighting design Labor cost slightly higher to

luminaires Dependent on existing

luminaire and installer

LED Retrofit Lamps Focus is more on wattage

reduction Worst lighting designs High risk of “misuse” / safety

concerns High labor cost

What is important?

How much energy is saved? How much does it cost? How long does it last? Is there enough light? How safe is it? How hard is it to install? How does it look?

degrees) • Light emitted directly below the fixture • Creates aesthetic and spacing issues

Maintenance Concerns o Wiring issues

• 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)

55

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

•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
