New York, N.Y. OSRAM Opto Semiconductors debuts its new compact, high-power OSTAR light-emitting diode (LED) at this week's Lightfair International 2005 conference. Setting new size and high brightness standards, the new LED offers more than 120 lumens output in a small 30 x 10-mm footprint. This new device can be used in both general and mobile illumination applications.
The OSTAR LED is available in red with a 120 lumens typical light output, true green with a 160 lumens typical light output, and blue with 36 lumens typical light output. The tri-color RGB version offers a rating of 120 lumens typical light output when tuned in white color.
Each OSTAR LED contains four high-power, thin-film indium gallium aluminum phosphide (InGaAlP) or indium gallium nitrite (InGaN) chips. 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, said the company. It can be mounted to lighting fixtures without any soldering, and it offers a surface-mount electrical connector. The LED itself can be mounted to a heat sink with a thermal paste for optimum heat dissipation.
"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, in a statement. "OSRAM is taking lighting to new levels by creating and enabling dynamic technological achievements to align with the visions of our customers."
Applications include colored and red-green-blue (RGB) white architectural lighting, fiber optics illumination, portable RGB light sources, medical lighting, aircraft illumination, automotive exterior lighting applications, and portable projection units.
An evaluation kit is priced at $65.00. The kit includes a four-chip OSTAR module that can be ordered with any combination of red, green and blue chips. Also included is a preliminary data sheet along with measured data. The OSTAR LED is currently available for sampling with a delivery of eight weeks. Production volume is scheduled for fourth quarter 2005. Click here for a preliminary OSTAR datasheet.
