Bivar Introduces Industry's First TO-92, Extended-Life High Powered Ultraviolet LED Available in Multi-Chip and Cluster Arrays



IRVINE, Calif. - Oct.7, 2002 - BivarOpto(TM), the Optoelectronics Division of Bivar, Inc., has introduced the industry's first extended-life high powered ultraviolet LEDs featuring typical radiant flux of 12mW per chip and a typical stable wavelength of 400nm. The series is ideally suited for a wide range of specialty applications including currency validation in vending and change machines, automotive instrumentation, counterfeit bill detection/bill validation, medical equipment, high-pressure hydraulic leak detection systems, test and measurement and security/biometrics.

The new Ultraviolet LED Series is housed in an all metal and glass TO-92 package that eliminates the life shortening degradation of the standard clear epoxy encapsulation. The UV-400-TO92 series is rated for over 20,000 hours of continuous operation at 30mA compared to the typical live expectancy of only 2,000 hours for other commercially available devices. Extended life minimizes product replacement costs, as well as associated labor costs that would normally be spent unsoldering epoxy lenses.

The metal base also acts as an effective heat sink offering increased forward currents up to l50mA under 1/10 duty cycle operation. The series can also be specified with multi-chip configurations allowing for compound intensities up to 36mW per unit and in large cluster arrays of up to 144 units per PCB.

Solid-state ultraviolet (UV) emission provides increased energy efficiency and related cost economies, as well as longer life over traditional, bulky, non-solid state UV lighting. BivarOpto's UV LEDs offer a desirable alternative for many types of portable or battery operated test and detection devices. For example, in the medical field, UV LEDs can be used as light sources for lower wavelength spectrum analyzers. In the security and law enforcement fields, the solid-state UV light can be used over traditional methods to detect counterfeit bills and provide accurate finger print identification.

The new Ultraviolet LED series features a 30-degree viewing angle and stable 400nm wavelength ranges from 390nm to 410nm. Other performance characteristics include an operating temperature range of -25°C to +85°C and a resistance to shock and vibrations not afforded by traditional filament lamps.

"To our knowledge, there is no other UV LED on the market capable of producing 12 mW per chip at 20mA with a stable wavelength," said Anthony Vilgiate, Bivar Vice President Strategic Business Development. "We have been very gratified with the initial response from our core customer base and surprised by the wide-ranging potential for this technology. Our continued development and close cooperation with industry leaders have lead us to introduce this latest rendition of our UV series. The potential for this technology is growing by leaps and bounds."

Immediately available from stock, typical pricing in production quantities is from $2.35 each. For more information, contact Bivar, Inc. at 800-SPACERS or visit Bivar online at www.bivar.com.
