POWERWEB AWARDED NAVY DEVELOPMENT CONTRACT FOR ADVANCED LED OPTICAL LIGHTING SYSTEM

MEDIA, PA April 3, 2006 Powerweb, Inc. announced today an award by the United States Navy to develop an advanced new lighting system utilizing LED (Light Emitting Diode) technology. LED lighting is the next generation of general illumination. LED lights consume 1/3 less power than fluorescent lighting and will last 10 to 20 years without replacement.

As the name implies, the LED is a semiconductor diode that emits light when a sufficient DC voltage is applied across the electrodes of the device. The color of the emitted light is directly related to the chemical composition and structure of the device. By adding controlled amounts of impurities or dopants, it is possible to vary the color of the LED. Currently, high brightness (HB) LEDs are available in every region of the visible spectrum. Consequently, LEDs are uniquely suited to provide the colors required of the luminaires used by the Navy. In addition the combination of blue, green, red and amber LED's can provide a high quality white light whose color temperature could be varied to match the outdoor daylight conditions, thus minimizing adaptation time in an indoor/outdoor transition.

Naval ships utilize four basic colors of light when at sea. These colors include white light, red light, amber light, and also a color for compatibility with the ships Night Vision Systems. Currently, naval shipboard lighting relies on colored filters over a white fluorescent or incandescent light source. Intensity of incandescent light sources ivaried through voltage based dimming. In addition, these colors change periodically based on the ships operating location and mission profile. The use of all of these colors at all different times means that the ship is maintaining two or more redundant lighting systems, one white, one colored, and one for NVIS.

Powerweb, Inc has designed a new LED based lighting system that can be utilized to replace the standard lighting on Navy ships. Through the use of thermal management, optical control of the light distribution, and effective color mixing to produce selectable colors with the greatest efficacy and color qualities, this new LED system will allow for multiple colored light output (white, amber, red & NVIS) based on the ships
operational procedures. In addition, the new system will have a new Optical Configuration & Polymer Enclosure Technology that will achieve the highest performance by integrating the optics of the LED light source with optics of the polymer enclosure, this will provide optimum performance for extraction of light from the LED and deliver this light in a well-defined distribution.
