LED offers brighter stage lighting solution
The device contains two-square-millimeter high-current chips per color which can handle a maximum of 4.5 A per chip and 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 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 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.
The high-power LED 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 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.
