Philips has announced the release of a wearable device that uses blue LED light to manage mild to moderate cases of psoriasis vulgaris. The device, which will be available through distributors this month in Germany, Netherlands and the U.K., is called Philips BlueControl and will offer an effective form of treatment for the skin condition without requiring medication. Psoriasis is a skin condition that effects 125 million people across the planet. Of those suffering from the condition, 80% have the most common form, psoriasis vulgaris. Also known as plaque psoriasis, the condition causes plaques on the skin in the form of red raised skin and flakey “scales” that arise when the skin cells die. Symptoms of the condition include itching, pain and cracking. Needless to say, the physical and psychological effects can be debilitating for those patients suffering from this disease. While the precise causes of psoriasis are unknown, it’s generally accepted that the condition arises following damage to the immune system, enzymes and other materials, which leads to uncontrollable growth of keratinocytes (immature skin cells that produce keratin, a tough protein found in nails, hair and skin) that triggers the skin flakes and inflammation as the body works to rid itself of the growth. Existing treatments to reduce the symptoms of the condition include topical applications, prescription drugs and UV phototheraphy—a treatment which taxes patients and medical services by requiring frequent visits to doctors’ offices. Looking for a better way to treat this incurable condition, researchers have found simple LED blue light treatment slows rapid cell division and can also reduce inflammation, which are the root causes of psoriasis vulgarsis. Conducting clinical trials in Germany, Philips worked with researchers at the University Hospital of Aachen to investigate the safety and efficacy of the Philips BlueControl device to manage...

In New York City, 300,000 to 400,000 people recently took to the streets calling for action on climate change. These concerned world citizens would be pleased to note that as we shift away from inefficient incandescent bulbs, those who choose LED lights are helping address climate change by minimizing humanity’s environmental impact. Electricity production is the single largest contributor to CO2 emissions, accounting for 38% of U.S. emissions from 1990-2012. LEDs help us address climate change by lowering our electricity demand and therefore lowering our CO2 emissions. While installing LED strip lights in your kitchen won’t stop global warming, if you choose to make the investment in LEDs, you’re doing your part to slow its progress. Here are the top environmental reasons for choosing LEDs over other conventional lighting sources: Energy Efficiency High quality LED lights work at 80% efficiency. That means that 80% of the electricity used by an LED chip goes straight into producing light. Compare that to an incandescent bulb, which in many cases is just 20% efficient — 80% of the electricity used is transferred into heat instead of light. The U.S. Energy Information Administration estimates that in 2012, lighting constituted 17% of the total energy used by homes and businesses in the United States. Switching our lights over to LEDs, making them use electricity with 80% more efficiency, would have a dramatic impact on our CO2 emissions. There are other cases where LEDs will come in handy as well, such as LED refrigerator display lighting and poultry farming, where we can further lower energy demands since cool LED running temperatures require less artificial cooling. Furthermore, LEDs produce directional light, meaning light isn’t wasted in directions where it isn’t needed. Less Waste The typical lifespan of an incandescent bulb is 750 to 1,000 hours. CFLs,...

The U.S. Department of Energy (DOE) has announced a $4 billion loan guarantee program to lower greenhouse gas emissions in the United States. LED lighting projects will qualify for the program. To qualify for the loans, projects must meet one of the following requirements: renewable energy systems; efficient electrical generation, transmission and distribution technologies; or efficient end-use energy technology (LEDs qualify as an efficient end-use energy technology). Applicants should have a project that is market-ready, replicable and would not likely be fully financed on a long-term basis by commercial banks. The DOE loan program is primarily geared toward renewables. LEDs are increasingly being incorporated with renewable technologies such as solar energy, and are helping to make renewable technologies more viable. The efficiency and reduced costs of solar-powered LEDs means they have already started to outperform electrical grid wiring in applications such as road and bus shelter lighting all the way from Boston to Abu Dhabi. The primary opportunity for LED lighting in this federal loan guarantee program lies in its compliance with the efficient end-use category. LEDs use 80% less energy than standard incandescent lighting. Not only that, but the advanced programing capabilities and rapid “on/off” switching of LEDs lend themselves to home automation projects and use in intelligent lighting projects aimed to reduce energy usage. LEDs are more efficient than other light sources because the vast majority of energy they use is transferred into light rather than heat. With an estimated 17% of the total energy used in commercial and residential sectors in 2012 going to lighting, the potential for LED energy savings across the nation is enormous. Initial applications for the federal guaranteed loan programs are due October 1, 2014, along with a $50,000 fee for the first phase of the DOE loan guarantee...

Chickens raised using an intelligent poultry LED lighting system have been found to produce higher quantity and quality of eggs, develop into maturity at a faster rate and enjoy an improved standard of health as compared to chickens raised under traditional light sources. Using LED-based technology chicken farmers can: Lower lighting costs Increase musculoskeletal development and weight gain Induce earlier maturity for hens destined to lay eggs Increase egg output and quality Regulate reproduction cycles Increase length of reproductive life Furthermore, farmers can adjust the color of the LED lights to promote certain outcomes. For example, using red light, farmers were able to stimulate sexual activity and reduce the amount of feed necessary to produce each egg — even though there was no difference in the size, or quality of the egg. The red LED lights were able to increase egg production by up to 38 per hen while decreasing food consumption by 20 percent. Green lights promotes chicken growth at early stages of development, while blue light promotes growth later along the life cycle of the chicken. Blue and green light improved feed conversion (the efficiency at which an animal converts animal feed into desired output such as eggs or meat) by up to 4%, and therefore reduced cost per pound of the chicken by up to 3%. Why is Poultry LED Lighting Superior to Traditional Poultry Lighting? Visible “white” light is actually composed of a range of colors, which can be viewed by refracting light through a dispersive prism. Incandescents, the most common form of poultry barn lighting, are missing many critical portions of the full spectrum found in sunlight. For instance, an incandescent bulb produces a highly diminished amount of both greens and blues. CFLs produce only narrow bands of color in...
