Three LED lighting pioneers share Nobel physics prize

LEDs hugely popular in British Columbia; Save on LED lighting this Offtober

BC Hydro's customers love smart new technologies, and nothing has been shown quite as much love as the ENERGY STAR® LED. One B.C. man did the math two and a half years ago, switching 124 lights in his home to LEDs after calculating that replacing energy-sucking incandescents would save him $11,000 over 20 years.

For that, we can thank two Japanese scientists and a Japanese-born American, winners this week of the Nobel prize for physics.

Isamu Akasaki, Hiroshi Amano and naturalized U.S. citizen Shuji Nakamura revolutionized lighting technology two decades ago when they invented blue light-emitting diodes. Red and green LEDs had been around since the mid-20th century, but the blue LED dramatically expanded LED use to home and business lighting, streetlights, computers and TVs.

At BC Hydro Power Smart, the task of getting customers to switch to LEDs has been relatively easy, at least since the price of LED lighting began to drop. Consumers across the planet now recognize that, even if LEDs are more expensive to buy, a light that lasts 22 years and uses at least 75% less energy than incandescent lighting is the smart choice.

“[The three scientists] succeeded where everyone else had failed," the Nobel committee said. "Incandescent light bulbs lit the 20th century; the 21st century will be lit by LED lamps."

The Nobel committee recognized the impact LEDs will have on the planet's resources, noting that about a quarter of world electricity consumption is used for lighting. For their work, Akasaki, Amano and Nakamura will split the Nobel award of about $1.1 million Cdn.
