OSRAM OPTO SEMICONDUCTORS REDEFINES LIGHTING AT LIGHTFAIR INTERNATIONAL 2005

OSRAM Premiers its OSTAR LED for Emerging Illumination Applications

New York, NY - (April 12- 14, 2005) - OSRAM Opto Semiconductors today announced it will premiere its revolutionary, versatile OSTAR(tm) light-emitting diode (LED) at LIGHTFAIR INTERNATIONAL 2005.  OSRAM's OSTAR LED, announced in October 2004, is a compact, high-power LED that offers more than 120 lumens output and measures 30x10 millimeters.  Setting new size and brightness records, the OSTAR LED provides extreme degrees of design flexibility, making the product ideal for both general and mobile illumination applications.

"OSRAM's OSTAR LED technology breakthrough enables new and exciting LED illumination application options for lighting designers and specifiers looking for brighter, compact light sources," said Ellen Sizemore, director, LED Products Group, OSRAM Opto Semiconductors. "OSRAM is taking lighting to new levels by creating and enabling dynamic technological achievements to align with the visions of our customers."

About OSTAR
Each OSTAR LED contains four chips in high-power, thin-film indium gallium aluminum phosphide (InGaAlP) or indium gallium nitrite (InGaN). Because OSRAM's thin-film chip emits light only from its top surface, the high chip luminance can increase the optical system efficiency and reduce the size of optics for lighting applications. The OSTAR LED is assembled in modules without a soldering process, and it offers a surface-mount technology electrical connection. The LED itself is screwed directly onto a heat sink with a thermal paste to achieve efficient heat dissipation. 

The OSTAR LED's high brightness, uniform light and low-profile package make it ideal for use in new general illumination applications.  These applications include colored and red-green-blue (RGB) white architectural lighting, fiber optics illumination, portable RGB light sources, medical lighting, aircraft illumination and automotive exterior lighting applications.  The OSTAR LED is also ideal for portable projection units that may be no larger than a deck of cards. 

Pricing and Availability
OSRAM's OSTAR LED is available in the following packages:

* Red - 120 lumens typical light output

* True Green - 160 lumens typical light output

* Blue - 36 lumens typical light output

* Tri-color RGB - 120 lumens typical light output when tuned in white color

The OSTAR is currently available for sampling, and production delivery is scheduled to begin in July 2005.  For more information, please contact your local OSRAM sales representative at www.osram-os.com.
