Up to 2.6 times the brightness from a component surface only 30 percent larger
OSRAM Opto Semiconductors presents a new LED for stage lighting. Compared with previous members of the product family, OSRAM OSTAR Stage offers more than twice the lumen output. At the same time, the component surface is only 30 percent larger. The new version contains two-square-millimeter high-current chips per color which can handle a maximum of 4.5 amps (A) per chip. This will enable moving heads for stage and exhibition lighting to be more compact and more powerful.
The new OSRAM OSTAR Stage is equipped with four high-current chips based on the latest thin-film and UX:3 chip technologies. With an area of 2 mm² each, the chips are twice as large as the previous ones but at 5.7 mm x 6.4 mm x 1.3 mm the package size is only slightly larger. Thin-film chips in red and UX:3 chips in green, blue and white are used. Up to 4.5 amps (A) can be applied to each chip, which allows more light to be produced from such a small surface area. With a binning current of 1.4 A the red chips achieve typical values of 140 lumen (lm), and the green chips 280 lm. The “deep blue” chip provides a light output of 1.8 watts (W). If the LED is operated at the maximum current of 4.5 A, the brightness per color increases by factor 2.6. The white chip in the new OSRAM OSTAR Stage will have a lifetime of 20,000 hours (L50/B50) at full output thanks to a new ceramic converter, achieving a brightness of more than 1000 lm.
Quality products in different output classes
The new OSRAM OSTAR Stage from OSRAM Opto Semiconductors is the latest high-output addition to the company’s LED product family for stage, exhibition and architecture lighting. “We are continually developing the chips and the package for the OSRAM OSTAR Stage family so that we can offer our customers high-quality products in different output classes”, said Wolfgang Schnabel, Product Marketing LED Industry at OSRAM Opto Semiconductors. “Our aim with this new LED is to raise the standard for moving heads in the high-output category.”
Compact spotlights thanks to high luminous intensity
The new OSRAM OSTAR Stage is the latest step by the Regensburg based company on the path toward high-power LEDs for stage spotlights which emit a large amount of light from a small surface area, leading to more compact spotlight designs. This family of products is ideal not only for stage lighting but also for moving heads and spotlights for trade fairs and architectural lighting.
The new OSRAM OSTAR Stage LED will be unveiled for the first time at the 2015 International Consumer Electronics Show (CES) which takes place from January 6 to 9, 2015 in Las Vegas, USA.
