- LED lights to save $50K annually for Bridge Authority – Poughkeepsie Journal: The New York State Bridge Authority has announced a new project to improve lighting around the Mid-Hudson Bridge through the installation of LED lights. The project, which will generate more than $53,000 in annual savings, calls for the installation of 174 LED lights. The project will cost $57,069 and include 120 street lights, 22 high mast lights and 32 tower lights.
Nowadays, LEDs are ubiquitous. Whether we’re talking about a football stadium, a street light, or nightlight, LEDs are used virtually anywhere lighting is needed.
What most people don’t know is that LEDs are also at the forefront of an “illumination revolution” in developing countries throughout the world.
While we live in a technologically driven society, we may not realize that access to safe and reliable electricity remains one of the key challengers plaguing more than 1.5 billion people in developing countries around the world.
Where do LEDs fit in?
According to International Finance Corporation, 2.1 million LED-solar products have been sold in countries that lack access to electrical grids.
In Africa — A growing portion of the more than 1 billion people living without reliable sources of electricity now have access to lights, thanks in part to LED technology. Nearly 5 percent of Africans without access to electricity — or some 28.5 million people — now use solar-powered LED lights.
A women in Senegal charges her cellphone using a port in her solar-powered LED lantern.
In India — Pollinate Energy has one simple mission: improve the lives of India’s urban poor by providing access to sustainable technologies, including solar lights and improved stoves for cooking.
With the help of LEDs and kerosene-free cooking equipment, local Indian communities can save money, experience reduced indoor smoke and enjoy better lights in homes and businesses.
Pollinate has already helped more than 25,000 people in Bangalore switch to solar LED lighting in their homes.
So how are LEDs changing the equation?
Eight to 10 years ago, the high cost of LEDs made them unrealistic for use in applications like this. But the efficiency of LEDs is rising, and prices are dropping, finally allowing LEDs to become a viable option.
The shift is taking place thanks to sapphire — the foundation for more than 95 percent of high brightness white LEDs. Large diameter sapphire wafers and patterned sapphire substrates contribute to greater efficiency and lower costs for LED lighting.

- Jefferson scientist’s study of SAD took him to space and back – philly.com: Lack of light is scientifically proven to be one of the most depressing things about winter. Neuroscientist George Brainard has been testing the biological impact of light and its connection with those who suffer from Seasonal Affective Disorder (SAD). His studies have led him to predict that LED lights will soon displace all other forms of lighting because they offer more flexibility in brightness and color, improving overall health and well-being.
- Making City Streets Smarter, More Efficient – Manufacturing.net: Lighting and software engineers are working on a new breed of LED street lights that contain sensors with the ability to gather traffic data. The traffic data collected could help ease congestion and help drivers avoid busy roads and intersections. These LEDs are building off of existing technologies that have the ability to dim outdoor lights when no one is around.
In August 2012, Rubicon Technology announced a ground-breaking project to produce large-area sapphire windows of optical quality for military sensing applications. Dubbed Large-Area Net-shape Crystal Extraction (LANCE), the project was supported by a contract from the United States Air Force Research Laboratory (AFRL) Electronic & Sensors Branch, Materials & Manufacturing Directorate, totaling $4.7 million over three years.
Fast forward to today.
Rubicon announced it has reached a key project milestone — successfully producing the first-ever synthetic sapphire crystal of its size and thickness, coming in at an incredible 36 x 18 x 2 inches.
Previous sapphire production methods were incapable of supporting the growth of quality sapphire at the size and thickness needed by the AFRL, so Rubicon developed a new growth platform to achieve the production of very large sapphire windows up to 2 inches thick. The process of creating sapphire of this size was incredibly complex and time-intensive, but Rubicon was determined to deliver a product unlike anything the market had ever seen before.
The military and other high-performance Industries desire sapphire at this size due to a variety of its qualities, including:
- Optical clarity in the visible and infrared spectra
- Abrasion resistance
- Thermal conductivity
Once thoroughly tested, the sapphire slab produced by Rubicon will be evaluated for use as infrared windows in extreme environments, such as space or the deep sea, where both durability and optical clarity are essential. The potential uses are almost limitless. Large-format sapphire will serve demanding applications in defense along with future commercial and industrial applications.
While the project is not yet complete, this is an encouraging breakthrough.

When you picture LED light bulbs, do your thoughts initially jump to how efficient, durable and cost-effective they are? After all, they represent the most recent advancement in the evolution of the light bulb.
But beyond their innovative qualities, do you ever stop to consider LEDs as beautiful, colorful or even artistic?
Photographer Patrick Rochon certainly does. Over the past few years, he has taken eye-catching photographs involving LED lights, long exposures and flash, making his stills appear as though he painted them with light. Rochon’s most recent work, Inspired Light, was done in collaboration with Infiniti Motors in Dubai and features SUVs with approximately 60 feet of LED strips carefully fixed onto them.
The images, which take weeks of planning and measuring to set up, are not digitally manipulated in any way. Instead, Rochon uses different exposure times and settings to create a single image. For this shoot, it took four experienced technicians four hours to prepare each vehicle.
