DOE Publishes GATEWAY Report on OLEDs in an Office Space

The Department of Energy’s GATEWAY program recently published a new report on a project prominently featuring OLED lighting at the Rochester, NY offices of DeJoy, Knauf & Blood, LLP, an accounting firm. One of the firm’s founding partners, David DeJoy, is also co-founder and CEO of OLEDWorks, the only US-based OLED manufacturer.

Among the key findings:

• The OLED panels are almost all driven by dedicated OLED drivers, and two of the luminaire types incorporate OLED panels with integral drivers, eliminating installation of a remote driver.
• The OLED luminaires are dimmable in almost all areas and exhibit virtually no flicker that would exceed the guidelines of the IEEE Standard P1789-2015 in either maximum or minimum output range of the dimmer.
• In nine months of operation, there have been no OLED panel or driver failures.
• While the efficacies of the OLED luminaires (21-58 lm/W) are well below those of the LED products (80-90 lm/W), projected efficacy for the next generation of OLED panels is 80-90 lm/W.
• The exposed OLED panels deliver soft, minimal-shadow lighting that makes faces and expressions visible and increases room brightness by delivering light to vertical surfaces. At the panel luminances used, this is achieved without employees reporting glare.
• Feedback from employees indicates they find the lighting system functional and enjoyable.

    Are there any comparisons made on the Luminance/sqmt between luminaires with OLED panels and luminaires such as mirror optics etc. I am studying the effect of high luminance LED sources on visibility of objects. The report mentions this metric only for OLED panels.

    Are there any observations made on stroboscopic effects from Wall or Ceing or Floor Mounted observed due to ceiling fans in residential or commercial applications.
