OLED Lighting in the Offices of DeJoy, Knauf & Blood, LLP Prepared for the U.S. Department of Energy Solid-State Lighting Program (July 2017) OLED Stakeholder Meeting Minneapolis, MN October 10 11, 2017
Gateway definition GATEWAY conducts field evaluations of high-performance SSL products to collect empirical data and document experience with field installations. GATEWAY provides independent, third-party data (unbiased) for use in decision-making by lighting manufacturers, users, and other professionals. Real-world installations often reveal product limitations and application issues that are not apparent from laboratory testing. GATEWAY typically documents pre- and post-installation light levels, color characteristics, energy intensity, and other performance attributes, and addresses application and maintenance of SSL products. DOE does not sponsor or pay for GATEWAY installations. All products studied in GATEWAY must be commercially available.
Objectives - DeJoy, Knauf and Blood (TeamDKB) Modern office space to attract and retain talent, convey leadership with customers, and incorporate energy efficient technologies including solid-state for all lighting solutions. Promote Rochester, New York as OLED technology center by providing real world, accessible, SSL experience for architects, designers and specifies.
Objectives - Department of Energy (DOE) Track SSL technology performance improvement over time. Identify technology challenges that impact performance and application of SSL. Spur continued advancements in SSL technology, product design, and application. Maximize energy efficiency and decrease U.S. energy use, while improving lighting quality. Note: DOE does not endorse any commercial product or in any way provide assurance that other users will achieve similar results through use of these products.

TeamDKB - An Accounting Firm Original Office: 1980 s rabbit warren layout T8 Fluorescents, 3700K, CRI 81, R9 6 New digs: 13,905 ft 2, open office design, combination of OLED (3000K) and LED (3500K)
TeamDKB - Office Layout OLED lighting used for- 1. Areas with low access to natural light 2. Exterior Partner offices long hours, lighting during night hours 3. Meeting and shared areas 4. Mother s Room (Zen room) 5. Add design elements in entry area
Commercially Available OLED Fixtures
Commercially Available OLED Fixtures Brite 1 OLEDWorks Lumiblade Panels in all fixtures except Acuity Brands Trilia and Olessence which used Brite 2 OLEDWorks Lumiblade Panels Visa Lighting has since qualified Brite 2 in the Limit & Petal for ~45% increase in efficacy Color: 3000K, Broad spectrum captures colors not measured in CRI Brite 1 Brite 2
Commercially Available OLED Fixtures Power: 1) Direct to wall power, drive multiple panels 2) Power conversion to 24VDC to single panel drivers Pendant hanging cords double as 24VDC supply Net fixture efficiency depends on driver and power supply chosen Controls: 0-10V wall dimming
Conference Rooms Trilia (Acuity Brands) Glare not an issue due to cosine light distribution 75 vs 300 vs 200 lumens More opportunities with smaller panel count. Birot Emphasizes thinness
Multipurpose Room Emphasize the LED vs OLED component and lighting results Brite 2 upgrade now available for Visa fixtures
Zen Room (Mother s Room) Unintended benefits (migraines) No blue LED option, rarely if ever used
Fixture Characterization
Only Flicker issue was due to customer s own driver
TeamDKB Feedback and Experience Positive, especially given the contrast to their previous office with fluorescent luminaires. The soft distribution of light from the OLED panels also produces relatively high vertical illuminances on walls and faces in a space, and reduces the sharpness of projected shadows from objects, much like the effect from indirect lighting. Also like the LED luminaires, although some find them excessively bright to view. They appreciate the soft, comfortable appearance of the OLED lighting, and enjoy showing a new kind of SSL to visiting friends and colleagues, and those that have explored the dimming options appreciate that flexibility. For OLEDS only, despite high luminance, none of the office occupants reported glare issues. Some said LED glare bothersome.
Team DKB Feedback and Experience Two people appreciated portable OLED lamp, especially for reading fine print financial documents Employees liked the ability to control light level with dimmers. The appearance of the OLED luminaires wins high praise from employees. Several commented that friends and family wanted to install the Visa Petal pendants in their own homes because they are residential scale, and neat-looking. Now training and conference rooms have dimming control, and that allows a uniform note-taking light that also illuminates the presenter s face without interfering with presentation screen visibility. One advantage of the OLED panels and their soft cosine light distribution is their ability to illuminate faces in a conference setting without harsh shadows.
Additional observations Power outage no failures No panel failures in 1 year operation for Brite 2 1 Brite 1 panel replaced but may have been power timing problem Costs: installation; product costs; maintenance
Impact Education and awareness Architects, developers, lighting designers Trigger orders Designers/developers love the light quality, direct light experience EXPERIENTIAL Customer collaboration Feedback on what decision makers need to grow market adoption TeamDKB Employees: Office feels contemporary, conveys leadership
