UM Startups Amaze As Tech Tour Continues
"ArborLight is working on mellowing the harsh, highly directional light emitted by LEDs by “spreading that light out, making it more glare free, by using wave guides and changing the color of the light.”
Initially ArborLight was working in replacements for T8 flourescent bulbs — but that’s a brutally competitive market. Intead, ArborLIght is working on something called daylight emulation.
“Daylight through a window has unique spectrum, temperature and dynamics, and it changes throughout the day,” Forbis siad. “It plays into one’s circadian rhythm, one’s alertness.”
So imagine having a skylight in a room stories underground, or in the middle of an office building under several floors above and far away from any window. ArborLight is creating ceiling fixtures that look amazingly like skylights. The light can be adjusted so that mornings and evenings, it’s more yellow and less intense. At noontime, it’s more blue and intense."

Arborlight: Hitting the switch on clean, high-quality fluorescent replacements
"ANN ARBOR, Mich. – A University of Michigan clean energy start-up looks to turn on investors and future customers to a new lighting technology that offers a cleaner, longer lasting and higher quality alternative to today’s fluorescent tubes.
Headquartered in the U-M Tech Transfer’s Venture Accelerator, Arborlight LLC develops sophisticated lighting solutions for clients and leverages its patent-pending technology to develop a light-emitting diode (LED)-based, drop-in replacement for linear, fluorescent tubes. These replacements are mercury-free, last more than 50,000 hours, and provide a cost-effective source of uniform, bright light – desired features currently unmet in the LED lighting market.
'Our current designs suggest that our lamps will be considerably more efficient, more durable and robust than today’s glass fluorescent tubes,' said Max Shtein, a U-M materials science and engineering professor, who with U-M Electrical Engineering and Computer Science Professor P.C. Ku, conceived of the lighting architecture at the heart of Arborlight. 'The opportunity here is tremendous because there are hundreds of millions of these kinds of fluorescent tubes being replaced every year in the U.S.
'In addition to this being a commercial opportunity, we could improve energy efficiency in lighting and eliminate over five metric tons of mercury from the waste processing stream each year in the U.S. alone.'"
