The US Department of Energy (DOE) has published another in its series of Gateway reports that evaluate the performance of real-world solid-state lighting (SSL) projects in general illumination applications. The latest Gateway project primarily uses OLED-based lighting, although some LED-based products were used to hit required light levels. The report states that the OLED lighting delivers light on vertical surfaces better than LED products and makes faces and expressions clearly visible, but the OLED products increase lighting power density relative to a primarily LED-based installation.

　　The latest Gateway report is based on the new offices of accounting firm DeJoy, Knauf & Blood, LLP (often called TeamDKB) located in Rochester, NY. David DeJoy is a founding partner at the firm and is also the founder and CEO of OLEDWorks — a manufacturer of OLED panels. OLEDWorks had pursued OLED panel technology on its own for years and then also acquired the Lumiblade OLED operation from Philips Lighting in 2015.

　　The TeamDKB office project uses luminaires from a number of lighting manufacturers, but all of the products installed are based on panels from OLEDWorks. The OLED lighting products were installed in what were called visually-prominent areas including partners’ offices, conference rooms, entry corridors and reception, and the break room and lounge area. Amber OLED fixtures were also installed in a Zen/mother’s room and OLED desk lamps are located on desks in many offices. Recessed and pendant linear luminaires and recessed downlights based on LEDs were used in other private offices and in the open office space.

　　As the nearby image reveals, OLED luminaires can make a compelling design statement. Some offices feature the Visa Limit OLED pendant with a zigzag form that directs light where it’s needed while also delivering style. Moreover, the Acuity Winona Trilia adds geometric ceiling elements while delivering diffuse light. We discussed Trilia relative to another DOE Gateway report on an office project last year. Visa’s stylish Petal pendants serve in a lounge area. Other OLED products used came from Birot Zhen, OMLED, and OLED Devices.
