DOE Shines $21M on Advanced Lighting Research

coondoggie writes to mention that the US Department of Energy is planning to fork over close to $21 million for 13 projects promising to advance solid-state lighting research and development. "SSL lighting is an advanced technology that creates light with considerably less heat than incandescent and fluorescent lamps, allowing for increased energy efficiency. Unlike incandescent and fluorescent bulbs, SSL uses a semi-conducting material to convert electricity directly into light, which maximizes the light's energy efficiency, the DOE said in a release. Solid-state lighting encompasses a variety of light-producing semi-conductor devices, including light-emitting diodes (LEDs) and organic light-emitting diodes (OLEDs). "

Re:Save energy: don't send so much light into spac

There are also studies linking light pollution to increases in breast cancer. On the face of it, might seem a little whacky, but basically the theory is, light at night causes decreased endogenous melatonin production (it doesn't take much light to cause a significant drop in melatonin production) Melatonin is a strong anti-oxidant that they theorize helps keep breast cancer in check. Anyway, that's the current theory to explain the studies.

Interesting. Do you have any references for properly lighting your home for maximum crime deterrence?

I have a streetlight right in front of my house, but have still had a couple minor criminal incidents.

Hmm... if you have trichromatic light of wavelengths 570nm, 540nm, and 430nm shining on an object that absorbs everything except 550nm, then the object will appear black won't it? Whereas if true white light were shining on it, it would reflect the 550nm wavelengths and our eye would interpret that as... yellow or something. Is that wrong?
