Osram Opto Semiconductors has extended their Duris product portfolio with a compact version without a classic package. The Duris S2 is in the low to middle output range and offers a high typical luminous efficacy of 160lm/w. It has excellent color homogeneity and color stability and capable of achieving homogeneous illumination in LED products designed as replacements for fluorescent tubes.https://cdn.specpick.com/images/photonics/duris_s2_gw_sblma1_ec_300.jpg712370

It is compact with dimensions of 2.0 mm x 1.6 mm. The LED is ideal for linear lighting solutions. With an emission angle of 150°, this 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. This in turn enables the number of LEDs and therefore costs also to be reduced. 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 S2 is the first Osram LED that uses an epoxy molding compound (EMC). Due to this material, the Duris S2 has a longer life of up to 50,000 hours. This is more than that of the existing Duris products such as the sister LED Duris E 3 that has a lifetime of 35,000 hours.

The S2 is the smallest LED in the Duris family. The new product joins the existing S5 and S8 versions. The new Duris S2 is available in different correlated color temperatures such as 3000, 3500, 4000 and 5000 kelvin (K). From summer 2015 additional versions with color temperatures of 2700 to 6500 K will follow. The LED is currently being subjected to extensive quality testing.
