- Humble light bulb helps Japan fill nuclear gap – Chicago Tribune: When the Fukushima nuclear meltdown of 2011 resulted in the closure of many of Japan’s reactors, a national campaign was started to reduce energy consumption. Since the start of 2012, 73 million LED light bulbs have been sold in Japan, comprising about 30 percent of all bulbs sold there. As LED adoption continues to increase, the country is also pursuing alternative energy sources such as solar power to help relieve the pressure caused by the shuttering of its nuclear energy program.
- Revamped Dubai park to bask in the sunshine – Khaleej Times: Al Khazan Park – which officially opened to the public on March 2 – has been revamped into Dubai’s first sustainable park. An off-grid solar power system and LED lights will reduce the amount of CO2 emissions annually by 44.5 tons, which is the equivalent to saving 1,100 trees.
- Europe to have 2.9 bn general lighting LED lamp installations by 2019 – Greentech Lead: According to an ElectroniCast Consultants report, the number of LED lights installed for general lighting in Europe will grow at an average annual rate of 58.7 percent, rising from 288 million in 2014 to 2.9 billion in 2019. The European market is predicted to grow at a slightly faster rate than the U.S. market during the same time frame. Europe is expected to maintain its leadership in relative market share throughout the forecasted period.
- SF Ferry Building Gets Makeover for World’s Fair Centennial Anniversary – ABC 7: To celebrate the centennial anniversary of the San Francisco World’s Fair, the iconic Ferry Building has been lit up the same way it was when the fair opened in 1915. Only this time the building will be lit up with nearly 1,100 energy efficient LED lights. The lights will stay up through December with two large beacons commemorating the year 1915.
In honor of the 75th anniversary of the Bay Bridge, the city of San Francisco and non-profit Illuminate the Arts unveiled a new light exhibition, The Bay Lights, a 1.8 mile-long installation of 25,000 white LED lights along the West Span of the bridge that spans San Francisco Bay from San Francisco to Oakland. The LED lights are on from dusk until 2:00 a.m. for the length of the two year exhibition.
The project was created by world renowned light artist Leo Villareal. Known internationally for his light sculptures and site-specific architectural work, Villareal’s art is in permanent collections of prestigious museums including the Museum of Modern Art in New York and Naoshima Contemporary Art Museum in Kagawa, Japan.
According to Villareal in LEDs Magazine, “This isn’t about just lighting another bridge with white or colored light. The Bay Lights emphasizes the use of intelligent lighting, fully utilizing individual control and the ability to create 255 levels of brightness per node.”
The project uses Philips Color Kinetics eW Flex SLX product in a 4200K CCT. These LEDs are made up of flexible strings of individually controllable white LED nodes that are attached at 1-ft intervals on the suspension cables. Each cable features LEDs that light up in specially programmed patterns including animations moving across the span, multi-dimensional waves of movement, and light-level changes for impact.
For the energy conscious, The Bay Lights is estimated to cost $11,000 in energy a year. The Bay Lights organizers believe that the project will bring upwards of $100 million to San Francisco in tourism revenue. While not visible to travelers on the bridge itself, San Francisco’s Mayor Ed Lee believes that an estimated 50 million people in San Francisco and the North and East Bay will eventually see the lights.
