According to estimates from industry analyst firm Strategies Unlimited, the LED street and area lighting market in 2010 was $327 million. The market is expected to increase at a compound annual unit growth rate of approximately 26 percent from 2010 to 2015. North America, Europe and China lead in the deployment of LED lighting technology.
"The deployment of high-performance solid state lighting fixtures is accelerating and customers are beginning to benefit from the improved efficiency and longer lifetimes these products deliver," stated Roger Holliday, vice president of Marketing for Microsemi's Analog Mixed Signal Group. "Microsemi's leadership in power conversion and light management, combined with our analog mixed-signal design expertise and unique supply chain setup, is why fixture manufacturers globally are choosing us as their lighting solutions technology partner."
"Street lights often represent one of the highest operating expenses for municipalities because of electricity, maintenance and replacement costs," said Irene Signorino, director of Marketing for Microsemi's Analog Mixed Signal Group. "LEDs help solve this issue by minimizing energy consumption and reducing replacement frequency. If dimming and thermal protection are supported in conjunction with the elimination of the step-down transformer losses as in our new driver, operating costs can be decreased even further."
In Canada and in the United States, power is often distributed to an outdoor lighting fixture at 347V or 480V. The fixture must then convert the power to much lower voltages (often less than 60V in the U.S.) to properly drive the LED. Until now, this conversion was accomplished using bulky and inefficient step-down transformers. Microsemi's LXMG221D-0700040-D2F eliminates the need for these transformers, accomplishing the voltage conversion in one step. In addition, since multiple power supplies can be used in a modular fashion, many models of street lights (40W, 80W and more) are supported.
Undetected and unreported non-functioning fixtures are a key issue for municipalities responsible for the illumination of public areas. Microsemi's new LED driver includes fault detection and management capabilities, which can allow operators to address this issue and respond more quickly to light fixture failures.
pursuing energy-saving light-emitting diode equipment, which will save money in the long run, according to City Manager Ed Gil de Rubio. LED lights will increase the original $200,000 lighting budget by $80,000. That figure is $40,000 less than projected costs using traditional lights, and would stretch the payments from three to seven years. That would lower the city’s 2012 payment from $156,000 to $75,400.

LED (light-emitting diode) lights as a way to address the needs of photographers working on motion projects. “Moving photographs,” as Ferri calls them, which are essentially stills that come to life and have no narrative, have become increasingly popular for online and tablet usage, especially with fashion clients. However clients rarely have the time or the budget to retouch the motion projects frame-by-frame. “When you are doing video particularly, you need to have control [of the light] so you don’t have anything to fix after,” Ferri says. “That’s a big thing.”

The 5-year extension of the partnership was sealed this afternoon in the Rijksmuseum by Frans van Houten, CEO of Philips, and Wim Pijbes, General Director of the Rijksmuseum. The Night Watch was relit for the occasion by Philips, combining innovative LED lighting with an advanced light control system. The new lighting will help reduce the Rijksmuseum’s energy consumption.
LED technology has been developed to the point that the Rijksmuseum felt it needed to adopt this innovation. The new lamps ensure optimal color rendering, lending an even greater expressive quality to the objects. In terms of light quality, the LED solution easily outstrips the halogen spot, praised for its warm color and broad spectrum.
A key element in the partnership between Philips and the Rijksmuseum lies in the intensive exchange of knowledge between the two parties with regard to the development of LED solutions for lighting art and architecture.
As Founder, Philips has been involved since 2001 in the biggest restoration and renovation project in the 126-year history of the Rijksmuseum. During the renovation, the highlights of the Golden Age have been on display in the Philips Wing, attracting an average of 950,000 visitors a year since it opened in 2003. Starting in 2014, major exhibitions will be held in the wing, which will be permanently named the Philips Wing. From 2013 onward, the Rijksmuseum expects to welcome about 2 million visitors each year.

$15 million more. The Livermore company seeks ways to make more efficient lights using LEDs. It hopes to have a product on sale in 2013.
Diamond Jo Casino replaced 750 of its existing incandescent down lights with Cree LRP-38 LED lamps. Since the casino lights remain on at all times, installing LRP-38 lamps, which are designed to last 35,000-50,000 hours (depending on application), can result in significant energy and maintenance savings. By eliminating the need for regular bulb replacements and associated labor costs, Diamond Jo anticipates reducing maintenance costs by nearly $23,000 a year while providing high-quality lighting throughout its facility. According to Chad Darter, Director of Facilities at Diamond Jo Casino, the long lifetime and high color quality of the LED lighting is a great match for the 24/7 operation of the casino.
According to lighting contractor Crescent Electric Supply Company, switching to Cree’s LRP-38 lamps, which consume only 11 watts of power compared to 100 watts from the original PAR-38 incandescent lamps, can save Diamond Jo Casino more than $46,000 in electrical costs annually. These savings, combined with anticipated maintenance savings result in a payback calculation of nearly one year for the installation with an ongoing annual savings of almost $70,000.
The casino was built in 2007 specifically to achieve “carbon neutral” certification under the Clean Air Conservancy's NetZero program. In addition to the energy-efficient LED lighting, the casino’s other green features include: a white roof designed to reflect heat and conserve energy, bar floor of reclaimed wood and a central plant heating and cooling system. In its partnership with the Clean Air Conservancy, Diamond Jo initiated the “Go Green Challenge” for Dubuque residents and businesses, as well as the Diamond Conservation Fund, including an annual commitment from the casino to help fund conservation efforts within its community.

Designed to meet today's demanding energy and environmental needs, Cooper Lighting's LightBAR technology features the company's patented AccuLED Optics, which sets the industry benchmark for reliable photometric performance, scalability and energy efficiency. The system's unique application-specific design allows lumen and energy output to be customized to fulfill the exact needs of the outdoor space--eliminating wasted energy and obtrusive spill light. Designed for both new construction applications or to replace inefficient luminaires, the next generation LightBAR technology is available in two versions (7 LEDs and 21 LEDs), three standard color options (3000K, 4000K and 6000K correlated color temperatures (CCT)), and offered in 13 different optical distributions, providing versatility for every outdoor need, including street lighting, area/site, floodlighting, wall mount, parking garage, canopy and pathway solutions.
The updated LightBAR technology offers an increase in efficiency in all optical distributions without degrading optical performance, lumen depreciation or lumens per watt (lm/W). Boasting more task lumens per watt, the high efficiency 21 LED LightBAR optical fixtures deliver up to 100 lm/W or 2400 lumens per LightBAR, which outperforms the original 21 LED LightBAR fixture (1800 lumens) by 600 lumens - (using the same number of AccuLED Optics) -, while the 7 LED LightBAR optical choice (1900 lumens) also increases its lumen output over the original 21 LED LightBAR.
The efficiency and performance improvement roadmaps of LED technology guarantee the availability of improved lm/W packages in the future. To address future retrofits of higher performing packages, Cooper's unique LightBAR design is backwards compatible or future-proof both electrically and thermally, meaning there are no changes to the driver or the heat sink, making future LED upgrade replacements to its fixtures simple.
Cooper Lighting also expanded the color options to include a 3000K and 6000K CCT as standard in addition to the preferred color choice, warm white color of 4000K CCT. While typical LED outdoor solutions are standardized on a cold blue color temperature (6000-6500K CCT), Cooper Lighting LightBAR-equipped fixtures, by comparison, provide specifiers and end-users a desired color choice.
Cooper Lighting's LightBAR technology provides energy savings between 30-75% over standard H.I.D. systems while also providing a 50,000+ hour rated life-six times longer than the traditional metal halide sources found in most outdoor commercial applications.
The LightBAR technology, integrated into the industry's leading portfolio of outdoor product lines represented across four of Cooper Lighting's company brands - Invue, McGraw-Edison, Lumark and Streetworks, - offers lighting solutions that qualify for many local utility rebates.

Traditional NVG filtering is achieved by fitting a filter to the full display area, which dims the image and adds an undesirable green tint that is visible in both daytime and nighttime operations. With CWCEC's Dual LED Backlit Skyquest Displays, this filter is removed from the front of the screen. Instead, the filtering occurs in the backlight located behind the LCD. A simple toggle switch enables the selection of either white daylight LEDs or green NVG-filtered LEDs integrated in the backlight within the display, providing complete control over the type of light emitted from the screen. The result is a very high brightness, full color image readable in direct sunlight during daytime operations, and a fully filtered display ideal for NVG operations.
"Our new Dual LED backlit Skyquest displays provide a high performance upgrade to older cathode tube technology and a truly unique way of achieving Night Vision Goggle compatibility," said Lynn Bamford, vice president and general manager of Curtiss-Wright Controls Embedded Computing. "We are introducing new LED displays across our product range, that can be used by system integrators as standalone displays or as part of an intelligent, centralized Skyquest multi-display video management system."
The new LED displays provide a number of significant advantages over older cathode tube technology. Because they use solid state devices instead of glass tubes, the LED displays are much more rugged as issues associated with the mounting of glass tubes and shock breakage are eliminated. LED displays, which offer highly precise brightness control, enable the system integrator to create different lighting regimes for different application areas.
About Skyquest VMS systems The Skyquest VMS surveillance system uniquely delivers video switching, recording, and display capabilities. It provides extensive, flexible video management capability including touch screen control, multiple video sources on any display, and direct control of recorders all from any of the on-board rugged video displays. The Skyquest VMS is currently fielded with leading law enforcement and military customers throughout the world, including UK Ministry of Defense (MOD), most UK law enforcement operators, and the U.S. Army Air National Guard.
