Osram’s four-chip OSTAR Lighting Plus offers powerful, efficient and surface-mountable incandescent replacement

Osram Opto Semiconductors GmbH of Regensburg, Germany says that, due to its high brightness and color stability, its new OSTAR Lighting Plus LED can be used without any problems in retrofits for incandescent lamps or halogen lamps. Containing four chips fabricated in UX:3 chip technology and emitting either cold-white or warm-white light, the new LED provides a large amount of light from a small area and improves efficiency compared with its predecessors.

Brightness is 425lm (5700–6500K) or 365lm (2700–4000K) at an operating current of 350mA, corresponding to typical efficiency of about 100lm/W or 80lm/W, respectively. “OSTAR Lighting Plus is also very efficient at higher currents and offers high light output thanks to the extremely uniform flux distribution over the entire chip surface,” says Andreas Vogler, marketing manager General Illumination (SSL). The greater brightness level per chip area suits applications where space is tight, such as LED luminaires and retrofits, he adds. Homogenous white light is ensured by an ANSI-compatible binning system with finely graded classes. The LED is also easy to handle due to its compatibility with surface-mount technology (SMT), says the firm.

With a power draw of less than 5W, the 365lm output of the warm-white OSTAR Lighting Plus is much brighter than a 25W incandescent lamp, which manages just 220lm. Energy savings of more than 80% can therefore be made despite a luminous flux that is 65% higher. Only four OSTAR Lighting Plus units are therefore needed to replace a frosted 100W incandescent lamp. Also, the color rendering index (CRI) is 80.

Applications for the new power LED cover interior lighting for shops, offices and homes, including many applications that require strong directional light from a small unit, such as spotlighting. The small dimensions of OSTAR Lighting Plus also suit applications that are currently being served mostly by halogen lamps.

OSTAR Lighting Plus will be premiered at November’s electronica 2010 show in Munich, Germany and will be available on the market at the start of 2011.
