Osram ‘s OSTAR LEDs Put Predecessors in the Shade
The firm says only four OSTAR Lighting Plus units are needed to replace a frosted 100 W incandescent lamp with a color rendering index of 80.
OSTAR Lighting Plus is the new power pack from Osram Opto Semiconductors, providing a large amount of light from a small area and putting its predecessors firmly in the shade in terms of efficiency. With its impressive brightness and color stability this high-power LED can be used without any problems in retrofits for incandescent lamps or halogen lamps. It contains four chips fabricated in state-of-the-art UX:3 chip technology and emits either cold white or warm white light.
impressive brightness and high color stability in different white tones.
The LED has a brightness of 425 lm (5700 K to 6500 K) or 365 lm (2700 K to 4000 K) at an operating current of 350 mA. This corresponds to a typical efficiency of around 100 lm/W or around 80 lm/W.
“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,” said Andreas Vogler, Marketing Manager General Illumination (SSL) at Osram Opto .“The greater brightness level per chip area makes the OSTAR Lighting Plus ideal for applications where space is tight, such as LED luminaires and retrofits.”
Homogenous white light is ensured by an ANSI- compatible binning system with finely graded classes. The LED is easy to handle thanks to its SMT compatibility.
With a power draw of less than 5 W the warm white OSTAR version produces 365 lm – and from only four chips – which is much brighter than a 25 W incandescent lamps which manages only 220 lm. Energy savings of more than 80% can therefore be made despite a luminous flux that is 65% higher – a major contribution to energy-efficient lighting.
Only four OSTAR Lighting Plus units are needed to replace a frosted 100 W incandescent lamp. And a color rendering index of 80 is no less impressive.
The 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 make it ideal for applications that are currently being served mostly by halogen lamps.
Osram Opto Semiconductors, a subsidiary of Osram offers its customers solutions based on semiconductor technology for lighting, sensor and visualization applications. The firm has production sites in Regensburg (Germany) and Penang (Malaysia). Its headquarters for North America are in Sunnyvale (USA), and for Asia in Hong Kong.
