Light-emitting diodes, or LEDs, have become popular with backpackers and cyclists who mount them on headbands for a reliable, hands-free source of illumination. Now, a new lab at Commerce's National Institute of Standards and Technology (NIST) is helping to bring these tiny but brilliant devices into your home, to help save both energy costs and the environment.
“LEDs can be very energy efficient, and they are a lot smaller and last a lot longer than light bulbs,” says NIST vision scientist Wendy Davis. “They’re what we’ll likely use in the future to light our houses and public places.”
It’s a vision of illumination’s future. And to realize it, Davis, along with Yoshi Ohno and a team of physicists, created the NIST Spectrally Tunable Lighting Facility (STLF). Their main goal is to improve the quality of the light that LEDs produce, so that when you turn them on, home feels homey. Read more | YouTube video
