Osram launches 1W ultra-white LED for general lighting

Osram Opto Semiconductors GmbH of Regensburg, Germany has launched the 1W-class ultra-white OSLON SSL LED, available in a package that measures just 3mm x 3mm.

Osram Opto says that is properties provide the basis for high application efficiency due to its high luminous efficacy (typically 100lm/W) even at high current, as well as its simplified thermal management, high reliability and a beam angle of 80° (suiting the injection of light into external lenses). The light emission meets the requirements for use in general lighting, including use as a replacement for halogen lamps in spotlights, desk lights, reading lights and ceiling floodlights (as well as retrofit applications), says Osram Opto.

“Its ability to handle high currents efficiently enables our customers to create particularly energy-efficient and cost-saving lighting solutions,” says SSL marketing manager Dr Gunnar Moos. “Its low thermal resistance of 7K/W simplifies thermal management,” he adds. If particularly strong light is needed, several light sources can be combined in a cluster. In addition to ultra-white (5700-6500K), the LED will be available this summer in neutral-white and warm-white color temperatures (ranging from 2700K to 4500K).

At an operating current of 350mA, the OSLON SSL achieves a typical brightness of 110lm in ultra-white (5700 and 6500K), with a maximum possible luminous flux of 130lm at present. At an operating current of 350mA and a color temperature of 3000K, it achieves a typical efficiency of 75lm/W and a brightness of 85lm. Also, brightness is 155lm at an operating current of 700mA (warm white). Applications that demand high lighting levels can therefore be achieved using fewer LEDs, says he firm.
