Sunnyvale, Calif., (May 5, 2015) - Osram Opto Semiconductors extends its Duris product portfolio with a compact version without a classic package. The Duris S 2  is in the low to middle output range and offers a high typical luminous efficacy of 160 lm/W, excellent color homogeneity, and color stability. This new DURIS LED is capable of achieving homogeneous illumination in LED products designed as replacements for fluorescent tubes.

Due to its compact footprint of only 2.0 mm x 1.6 mm, this space-saving LED is ideal for linear lighting solutions. With an emission angle of 150 degrees, this chip-size LED emits more light to the side than LEDs with classic packages. Therefore, the light is better distributed in linear lamps and luminaires, and hot spots, or visible points of light, are reduced. This enables a reduction in both the number of LEDs and costs. By overdriving the LED up to 150 mA, the range of applications for the new Duris S 2 can be extended to recessed ceiling luminaires and panel luminaires.

The Duris S 2 is the first Osram LED to use a new lead frame material made out of an epoxy molding compound (EMC).

“Due to this lead frame material, the Duris S 2 has a longer life of up to 50,000 hours”, said Marc Dyble, Marketing & Business Development Manager for General Lighting at Osram Opto Semiconductors. “This  new product exceeds the life of existing Duris products such as the  E 3, which has a lifetime of 35,000 hours. Other products featuring this technology will follow.”

The S 2 is the smallest LED in the Duris family measuring only 2.0 mm x 1.6 mm and joins the existing S 5 and S 8 versions. The Duris S 2 is available in different correlated color temperatures: 3000, 3500, 4000 and 5000 Kelvin (K). Additional versions with color temperatures of 2700 to 6500 K will follow in the summer of 2015. This new LED is currently undergoing extensive quality testing. The certification process, based on the LM-80 standard, is in progress and the results are expected to be available in the winter of 2015/2016.
