Watch the world's largest LED light sculpture in action July 23 2013

SAN FRANCISCO On March 5, the "Bay Lights" project made its official debut as the world's largest LED light sculpture. Created by light artist Leo Villareal, the installation includes more than 25,000 individually programmed LEDs strung along more than 100,000 feet of suspension cables on San Francisco's Bay Bridge. Inspired by the bridge's 75th anniversary, the sculpture will remain in place until 2015.

Taking his inspiration from nature, Villareal developed custom software to program the never-repeating light patterns and formations that appear on the bridge at night. The energy-efficient white LED lights will cost approximately $11,000 a year to power, and dedicated solar panels installed in nearby Davis, California, will offset the energy used. The project is presented by Illuminate the Arts, a San Francisco nonprofit dedicated to the creation of community-activating public art. 

Wanted: An LED Lamp That Could Outlast You October 07 2011

BY TAPPING MICROPROCESSOR COOLING TECHNOLOGY, INDUSTRIAL DESIGNER JACK DYSON DEVELOPS AN LED LAMP THAT CAN LAST 12 HOURS A DAY, FOR 37 YEARS.

LEDs are the best lightbulbs to meet the demands of an environmentally enlightened future, but they’ve got a dirty little secret: They aren’t always as efficient as advertised. One of the biggest problems is that they overheat, which chisels away at the bulbs’ life span. According to data from the Lighting Research Center, an LED at 45 degrees Celsius might last for about 100,000 hours, whereas an LED at 85 degrees Celsius might deteriorate in as few as 10,000 hours.

British industrial design studio Jake Dyson Products believes it has invented a way to extend LEDs’ longevity by tapping technology originally developed for satellites (now commonly used to cool microprocessors). Shaped like a construction crane, the CSYS LED task light has a pipe in the horizontal arm that conducts warmth away from the LEDs (at the arm’s tip) and discharges heat evenly over the rest of the arm. That keeps the light source cool enough to last 160,000 hours, or 12 hours a day for about 37 years, according to the studio’s calculations. As they tell it: "The chances are the LEDs will last longer than you do!"

The CSYS LED task light debuted at Designjunction during the London Design Festival late last month. It’ll be available in the United States in May for approximately $925.
