Osram presents 'borderless' chip-size Duris S2 LED as fluorescent tube replacement

Osram Opto Semiconductors GmbH of Regensburg, Germany is extending its Duris product portfolio with a compact version without a classic package. Joining the existing S 5 and S 8 versions, the Duris S2 is in the low to middle output range and offers a high typical luminous efficacy of 160lm/W (at 65mA) and what is claimed to be excellent color homogeneity and color stability. It is therefore capable of achieving homogeneous illumination in LED products designed as replacements for fluorescent tubes.

Due to its compact footprint of only 2.0mm x 1.6mm, the space-saving LED (the smallest in the Duris family) is suitable for linear lighting solutions. With an emission beam angle of 150°, the chip-size LED emits more light to the side than LEDs with classic packages. The light is therefore better distributed in linear lamps and luminaires, and hot spots (visible points of light) are reduced, says Osram. This in turn enables the number of LEDs and hence costs also to be reduced. By overdriving the LED up to a current of 150mA, the range of applications for the new Duris S 2 can be extended to recessed ceiling luminaires and panel luminaires.

The S 2 is the first Osram LED to use a new lead frame material, an epoxy molding compound (EMC). "Thanks to this material the Duris S 2 has a longer life of up to 50,000 hours," says Tony Tam, project manager responsible for the Duris product family. This is more than that of existing Duris products such as the sister LED Duris E 3, which has a lifetime of 35,000 hours. "Other products featuring this technology will follow," adds Tam.

The Duris S 2 is available in different correlated correlated color temperatures (CCTs): 3000K, 3500K, 4000K and 5000K. From summer, additional versions with color temperatures of 2700-6500K will follow. The new LED is currently being subjected to extensive quality testing. Certification based on the LM-80 standard (Energy Star) is in progress and the results are likely to be available in winter 2015/2016.
