Researchers develop tool to predict the level of driver discomfort caused by LED lighting
(Phys.org) —Long hours of nighttime driving can cause eyestrain because while our vision adapts to the surrounding darkness, the sudden stabs of brightness from streetlamps can be irritating, distracting ...
Lighter, cheaper, LED light bulbs are starting to enter the marketplace
Just when you were finally warming up to the idea of swapping out your old light bulbs with compact fluorescent ones, you may soon find a new alternative at your local hardware store.
New LED streetlight design curbs light pollution
Streetlights illuminate the night, shining upon roadways and sidewalks across the world, but these ubiquitous elements of the urban environment are notoriously inefficient and major contributors to light ...
New material for warm-white LEDs invented
Light emitting diodes, more commonly called LEDs, are known for their energy efficiency and durability, but the bluish, cold light of current white LEDs has precluded their widespread use for indoor lighting.
New kind of ultraviolet LED could lead to portable, low-cost devices
Commercial uses for ultraviolet (UV) light are growing, and now a new kind of LED under development at The Ohio State University could lead to more portable and low-cost uses of the technology.
