Layout started

We are starting the PCB layout today which will be used in both the 2 foot square rigid Virtual Skylight, it has 36 warm white and 36 cool white Luxeon LEDs on a very narrow strip pcb. The same strips will be used on the flex version. Next up will be a cool video showing […]

Roll Up Virtual Skylight

Ceiling invisibility cloak

The Virtual Skylight may be considered a form of invisibility cloak, in that the sky above is mapped to the ceiling panel in brightness and color. As such it is a single pixel wireless video link. Compare this to the Tower Infinity now going up in South Korea, and entire skyscraper coated in video screens […]

Juno’s Scott Roos on LEDs and Circadian Rhythms

For example, warm-to-dim LEDs used at home will certainly support better […]

Tunable white in health care

Health Facilities Management magazine (6May2015) highlighted the transition to mimicking daylight in health care. According to Lou Calvo, Director Sales & Marketing at Waldmann Lighting: The latest LED innovation is digital dimming and color control to create biodynamic lighting that replicates natural daylight throughout the day, experts agree. “This concept involves changing the color temperature […]
