- Monuments Around The Globe Are Turning Blue For Autism Awareness – BuzzFeed: In an effort to increase autism awareness, 13,000 buildings across the globe shined bright blue on the evening of April 1. An annual tradition since 2008, major world landmarks, such as the Empire State Building and its LED Lighting System, lit up blue in honor of World Autism Awareness Day.
- Taiwan Expanding Into Indoor LED-lit, Pesticide-free Farms – Lancaster Online: A new generation of Taiwanese farmers is growing vegetables indoors under bright LED lights in climate-controlled “grow rooms”. High-tech indoor farms are now yielding more crops per area than soil and because of the intensity of lights and nutrients provided in the water, plants grown under LED lights grow twice as fast.
- Hotels Light Up to Influence Human Behavior – Sourceable: Amongst furnishings and art, lighting is emerging as the most important factor that can evoke emotion and create ambiance for hotel guests. A case study by electrical firm Leviton, demonstrated how LED lamps are able to transform lobby areas with colors and aesthetics that couldn’t be achieved with standard incandescent lighting.
- LA Connects, Controls its LED Street Lights – Energy Manager Today: The Los Angeles Bureau of Street Lighting has implemented a new management system that allows it to remotely control the city’s LED street lights, along with monitor power usage. Made up of about 7,500 centerline miles of LED street lights, LA’s entire system can be managed remotely through any web browser, eliminating on-site commissioning.
We like to report on interesting applications using LEDs. This latest application we are focusing on takes LEDs and combines them with farming to leverage unique properties – temperature and wavelenghths — of LEDs to grow more, better plants, indoors without the use of pesticides.
Chicago’s Green Sense Farms takes advantage of LEDs to make the largest indoor commercial vertical farm in the United States. According to a report in Gizmodo, Green Sense Farms recently announced two new huge climate-controlled grow rooms in its Chicago-area production warehouse. Green Sense Farms combines towering racks of vertical hydroponic systems with Philips “light recipe” LED grow lights.
Philips is building a database of ‘light recipes’ for different plant varieties since each plant has its own needs for light. A Philips Horticulture “light recipe” is an instruction based on knowledge of how to use light to grow a certain crop under certain conditions. Because LEDs produce less heat than traditional lighting, the light fixtures can be placed much closer to the crops without fear of burning them— reducing the vertical farm’s footprint and ensuring that each leaf gets the light it needs.
Using the system, Green Sense Farms is able to harvest its crops 26 times a year while using 85 percent less energy, 1/10th the amount of water, no pesticides or herbicides, and reducing the facility’s CO2 output by two tons a month. And, to make the Earth a better place, it even produces an average of 46 pounds of oxygen daily.
