Smart Printing: Fraunhofer IAP Develops Power Generating Films and Luminescent Glass

They turn light into electricity or vice versa: the inkjet inks developed by researchers at the Fraunhofer IAP can be printed on solid substrates as well as on flexible foils. In effect, solar cells and organic displays can be produced fast and cost-effectively.

The great outdoor debate

You may have read in our March issue that outdoor lighting best practices continue to be disputed, with representatives from both the American Medical Association (AMA) and the Illuminating Engineering Society (IES) weighing in on controversial questions surrounding blue light, light levels, and CCT in outdoor area lighting and street lighting in particular. We plan to bring you more on the viewpoints that were raised by this reported Strategies in Light panel discussion back in February and are considering various delivery formats for that information.

Where Are the Street Lights Paid With Gold?

A recent report from Research and Markets indicates that municipalities will be converting streetlights to LEDs due to efficiency reasons, just like many other lighting applications. So why are distributors choosing to take a pass on this ripe market?

College campuses and outdoor lighting design: things to consider

During the darkest hours, people are still walking through campus — it’s pretty much a 24/7 operation even if it’s not a high-traffic time. From late-night library stints to postgame parties during football season, college campuses know no “closing time.” How can outdoor lighting address the unique needs of a college campus?

Tunable Lighting Put to the Test

Following the renovation of two floors of an existing hospital wing, the new Swedish Medical Behavioral Health Unit (BHU) opened to provide mental health services to the public. The nearly 15,000-square-foot BHU features 22 beds. ZGF Architects produced the design, which includes state-of-the-art lighting.

For the lighting, the designers wanted to blend the best of old and new based on biophilic/circadian design principles. They retained an existing outdoor space and a large skylight in the common area. They also specified downlights in BHU’s corridors and dining/activity space that provide both color tuning and dimming.
