UC Santa Barbara sues Amazon and IKEA over LED lighting
UC Santa Barbara has had enough of retailers selling its patented LED light bulb technology without authorization. This week, the university filed a lawsuit charging Amazon, IKEA, Walmart, Target and Bed Bath & Beyond with infringing its patents. According to Nixon Peabody, the law firm representing UC Santa Barbara, this is the "first-of-its-kind direct patent enforcement campaign against an entire industry."
Ultra-powerful laser could make incandescent light bulbs more efficient
Look, LED light bulbs are fanciful, great for Ma Earth and a fine addition to any home, barber shop or underground fight club. But let's be honest -- even the guy that bikes through blizzards to get to work and wears garb that he grew in his basement isn't apt to shell out $120 a pop to have what's likely the most efficient light bulb American dollars can buy. Enter Chunlei Guo from the University of Rochester, who has helped discover a process which could morph a traditional incandescent light bulb into a beacon of burning light without using nearly as much energy as before. In fact, his usage of the femtosecond laser pulse -- which creates a "unique array of nano- and micro-scale structures on the surface of a regular tungsten filament" -- could enable a bulb to increase output efficiency in order to emit 100-watts worth of light while sucking down less than 60-watts of power. Per usual, there's no telling when this new hotness is likely to hit the commercial realm, but one's thing for sure: we bet GE's paying attention.[Via Physorg]
