Highly-efficient LED modules rated for 50,000 hrs

OptoElectronix has introduced a new series of small, highly efficient, 180 LED modules designed for retail display lighting, appliances and task lights. The round, 60mm (2.35-inch) diameter, aluminum modules are engineered for optimal thermal management. They integrate the LED, lens and electronics, and are rated for 50,000 hours. The modules are designed to flush mount through a standard 44.5mm (1.75-inch) mounting hole with three screws, and the flange and lens are only 4mm (0.16 inches) thick.

These off-the-shelf modules will appeal to manufacturers who wish to offer their end users the significant energy savings and reliability of an LED solution. The ULE21VW1-F-25W, for example, offers 85 percent savings in total cost of ownership, including reduced maintenance and replacement bulb cost, as well as energy cost savings over a five-year period of continuous operation. In a commercial application this would equate to an amortization period of 21 months.

Each module uses about one-fourth the energy of incandescent lamps with comparable light output. All variants come in cool white (6,000K) and warm white (3,000K), and connect directly to 12VDC or 12VAC power sources. All four models have a 180 beam angle.

1. ULE21VW1-F-25W: 200 lumens at 3.6W, typical; 25W equivalent
2. ULE21VW1-F-38W: 450 lumens at 7.2W, typical; 38W equivalent
3. ULE21VW1-F-45W: 600 lumens at 10.8W, typical; 45W equivalent
4. ULE21VW1-F-60W: 900 lumens at 14.4W, typical; 60W equivalent.

Energy savings
The new ULE21VW1-F series is based on the OptoElectronix Universal Light Engine platforman important new lighting platform that provides the world's highest LED light output per watt with the lowest electrical losses. Unique, proprietary thermal design maximizes heat transfer and contributes significantly to the 50,000-hour life.

"We believe that the future of illumination is LEDs," said Chuck Berghoff, CEO of OptoElectronix. "The significant energy savings and ultralong service lives will make LEDs the only choice for illumination. LEDs can be immediately integrated into products today such as appliances, display cases, and light fixtures where they are ideal for both replacement and new design applications."

Berghoff says that the challenges for LED illumination have been in four areas: light output, color rendering ability, manufacturing cost, and configuration standardseach of which is intimately interrelated with the other. "We believe that we are at the forefront of LED-based illumination," he said.

The ULE21VW1-F-25W and the ULE21VW1-F-38W LED Universal Light Engine modules are available through Nu Horizons Electronics, www.nuhorizons.com/nusolutions/lighting/oei/, or at www.optoelectronix.com. The ULE21VW1-F-45W and the ULE21VW1-F-60W will be available on June 1.
