2.OSRAM Opto Semiconductors DURIS E5 LEDs introduction

OSRAM Opto Semiconductors DURIS E5 LEDs deliver a high efficacy of up to 112lm/W (at 6000K / 70 CRI) and a wide beam angle of 120o in a compact form factor (5.6mm x 3.0mm). These 0.5W LEDs are ANSI binned, ranging from 2700K to 6500K CCT, with CRI options between 70-85. The typical luminous flux ranges from 41lm (3000K / 85 CRI) to 45lm (6000K / 70 CRI) at 120mA. These features make OSRAM Opto Semiconductors DURIS? E5 LEDs ideal for homogeneous illumination applications where the DURIS E5 never fails to impress with its performance on system level. Packaging features and advantages for this series include die technology made with InGaN on Sapphire, and a white SMT package with colored, diffused silicone resin. Common applications for Duris E5 LEDs include retrofit lamps, task lights, white goods, and channel letters.

3.Official description about  Duris E5
Osram Opto Semiconductors presents a new Duris E5 with a significantly improved efficacy of more than 130 lm/W compared to the current version. A high color rendering index (CRI) of more than 90 and typically 95 enables high quality lighting solutions in shops or museums. Due to the same footprint and other common features the new mid-power LED can replace the current product versions very easily.
The new Duris E5 (GW JDSRS1.CC) will complement the well-known Duris product family of Osram Opto Semiconductors by mid of January 2015. With an improved efficacy of 131 lm/W at 4000 K and 120 mA it can perfectly be used for energy saving lighting applications. Furthermore, the new mid-power LED features an improved thermal conductivity as well as lower forward voltage (3.00 V at 120 mA). The optics are absolutely compatible to all members of the Duris family and the platform design is the same, so customers can replace the current LED versions easily.

The good color rendering of typically 95 makes the new Duris E5 ideal for applications in which the requirements for good quality of light are particularly high, e. g. professional lighting solutions in shops or museums, but they can also be used for non-directional indoor LED retrofits. The well-known package offers great design flexibility for the customers and facilitates the replacement of previous product versions, too.

The new LED is available with different color temperatures from 2700 to 4000 Kelvin (K). The certification process for the high lifetime standard of LM-80 is already under way and will be finished by early 2015.
