OSRAM Opto has released the new ultra-white Oslon SSL LED in a package measuring just 3 x 3 mm. The Oslon LED has a typical luminous efficacy value of 100 lm/W, and features simplified thermal management, high reliability and a beam angle of 80°. The Oslon LED is an LED in the 1 W class and meets the requirements for use in general lighting, like in spotlights, desk lights and ceiling floodlights.

“Its ability to handle high currents efficiently enables our customers to create particularly energy-efficient and cost-saving lighting solutions. The Oslon LED therefore has all the attributes to become the ‘green’ light source of the future”, said Dr. Gunnar Moos, SSL Marketing Manager at OSRAM Opto Semiconductors.

The Oslon LED has a thermal resistance of 7K/W. Its small size gives designers the flexibility to create extremely sophisticated solutions. If particularly strong light is needed, several light sources can be combined in a cluster. In addition to ultra-white (5700 to 6500 K), the LED will be available this summer in neutral white and warm white. Its color temperature will range from 2700 to 4500 K.

The Oslon SSL is manufactured using the latest chip technology, ensuring a high luminous efficacy. At an operating current of 350 mA this light source provides a typical brightness of 110 lm in ultra-white (5700 and 6500 K), with a maximum possible luminous flux of 130 lm at present. At an operating current of 350 mA and a color temperature of 3000 K it achieves a typical efficiency of 75 lm/W and a brightness of 85 lm. And when the operating current increases to 700 mA (warm white), the brightness is as high as 155 lm. The advantage here is that applications that demand high lighting levels can be completed with fewer LEDs.
