BridgeLux Raises the Bar with 60-mil ''Bulb Buster'' for the KO Family of Power-LED Chips; Solid State Lighting Packagers and OEMs Gaining New Choices.


SUNNYVALE, Calif. -- BridgeLux, Inc. (formerly eLite Optoelectronics), a leading supplier of energy saving, power-LED chips to high-volume solid state lighting market segments, today announced the introduction of the KO family of LEDs, including the only 60-mil chip available in production volumes today. Power-LEDs are generally recognized as those devices that operate at 350mA and greater current, and are appropriate for solid state lighting applications requiring maximum brightness in minimum space, including automotive forward lighting, camera flashes and general illumination. The increased efficiency and reliability of solid state lighting promises to help to reduce worldwide energy consumption and conserve our planet's valuable natural resources.

, "The development objective with the KO series was to reduce the input voltage while increasing the overall light extraction. The net result is a fully scalable family of LED chips that yields a 10-30% increase in its light output efficiency." Decreasing the input or "forward" voltage required for a given drive current results in a device with lower overall power consumption and lower heat generation for a given amount of light, all of which contribute to producing more "lumens-per-watt."

 or fluorescent bulb's space requirements. The KO blue family is available in 60, 40, 30 and 24-mil chip sizes (1.5mm to .6mm). The 1.5mm KO is the only 60-mil chip available in volume production today. Color choices range from 445 to 475-nm blue, as well as high efficiency cyan and green. Die bonding options include traditional silver epoxy epoxy

 as well as the newer eutectic techniques.

When combined with phosphors to generate white light, depending upon packaging design, the 60-mil KO can support up to 1.2A drive current enabling a targeted white output of 140 lumens. The entire family is designed to stand up to 150 degrees C junction temperatures Junction temperature is the temperature of the actual semiconductor in an electronic device. In operation it is usually higher than case temperature, the temperature of the part's exterior.  and 40% higher drive currents than is commonly found for similarly sized devices, all without compromising overall reliability. Dr. Walker commented that, "These chips are designed for brightness. Combining 6 of these devices produces roughly the light output of your typical 60-watt incandescent bulb bulb, thickened, fleshy plant bud, usually formed under the surface of the soil, which carries the plant over from one blooming season to another. It may have many fleshy layers (as in the onion and hyacinth) or thin dry scales (as in some lilies)—both of which , but requires less than one-third the power. We've nicknamed the 60-mil KO, 'the bulb buster' since we have something here that can really begin to challenge traditional lighting solutions in general purpose illumination."

With much of the early intellectual property in power-LEDs having been closely held A phrase used to describe the ownership, management, and operation of a corporation by a small group of people.

In a closely held corporation, the same people often act as shareholders, directors, and officers, and no outside investors exist.
 by just a few manufacturers, LED packagers have had limited access to merchant supply sources for power-LED chips. Those that had been available were often from suppliers who also produced their own packaged devices, effectively putting them in competition with their own customers. BridgeLux encourages the industry to respect IP, and advance the technology through competitive innovation. The company's power-LEDs are patent-protected and conformant to the recently announced intellectual property substantiation standards of the IP-Secure Lighting Alliance (www.IPSLA.org).
