Red-Blue LED Light Treatments Enhances Lettuce Photochemicals, Antioxidant Contents

Increasingly, vegetables are being efficiently grown using soilless techniques such as hydroponics. Hydroponic systems are favored for their ability to improve water and nutrient use efficiency and crop yields, and have the added benefit of allowing growers to use fewer chemical fertilizers. Researchers in China and United Kingdom studied the effects of LED light combinations on lettuce grown in hydroponic systems to determine whether the treatments could reduce nitrate accumulation, and to find out what effect the treatments might have on phytochemical levels.

DOE's Proposed Light Bulb Energy Efficiency Standards to Save Consumers an Annual US$12.5 Billion

New light bulb energy efficiency standards proposed by the U. S. Department of Energy (DOE) completed the gradual phase-out of inefficient everyday incandescent bulbs required under a 2007 law passed by a bipartisan Congress with industry support. And once all of America's approximately 4 billion lighting sockets contain energy-saving bulbs that meet the standards, U.S. consumers and businesses will save about $12.5 billion every year--and gain cleaner air and a healthier environment.

Smart Lighting Designs in LCD Backlight Proximity Sensors

One of the benefits of automating control systems within buildings is the ability to customize services and personalize a user’s environment; the human machine interface (HMI) is the gateway to such controls. The addition of proximity sensing is an underutilized improvement to many interfaces in an automated building ecosystem, including thermostats, security-system keypads, monitors and elevator call buttons. Proximity sensors can improve the user experience, decrease power consumption, and increase the life of the liquid crystal display (LCD) and backlight.
