Rutronik now has in stock the new Ostar Stage LEDs from Osram Opto Semiconductors. The LEDs offer high luminance of 48 Mcd/m² and tunable colour tones from cold white to warm white.
Two warm-white and two cold-white chips, arranged diagonally in the package, enable colours to be mixed perfectly at component level and allow all white tones between 2.700K (warm white) and 10.000K (cold white) to be produced with appropriate control. The LED achieves a high colour rendering index of 94 for warm white and 74 for cold white. Thanks to the low-profile design with a height of only 1.23mm, a footprint of only 5.9mm x 4.8mm and glass cover with an anti-reflective coating, the LED provides the basis for compact spotlights with an extremely narrow beam. The LED’s etendue in conjunction with external optics is retained, enabling the very narrow beam of light (+/-9°) to be produced. This beam is smaller by factor 2 than for spotlights based on plastic-encapsulated LEDs, consequently, the luminance of the spotlight is greater by factor 2.
Based on the Osram Ostar SMT platform, the Osram Ostar Stage is suitable for standard solder processes. The chips are fabricated in state-of-the-art-thin-film technology so that almost all the light produced internally is emitted at the top. In continuous operation the chips can handle an operating current of up to 900mA, which gives maximum values of 390lm in cold white (10.000K) and 210lm in warm white (2.700K). At a typical value of 1.8K/W the thermal resistance is very low and heat removal is therefore no problem. The LED’s life time is 50,000 hours. This LED is ideal for use in moving head spotlights on stage, for booth lighting and trade fairs and for architectural lighting.
