Osram extends LED portfolio in sub-1W power range

Osram Opto Semiconductors GmbH of Regensburg, Germany has launched a new LED product family in the low-power range, starting with the DURIS E 3.

The firm says that the small dimensions and wide beam angle of the new LEDs suit applications that require uniform illumination, and the highly efficient LEDs can be used as replacements for conventional fluorescent lamps in T5 or T8 luminaires for example.

The DURIS E 3 has been designed specifically for applications that call for uniform distribution of light, high efficiency and low procurement costs. The main areas of application are hence lighting systems in industry (such as open-plan offices), production facilities, conference rooms and warehouses that have been equipped with T5 and T8 luminaires. “Bright LEDs are also recommended for smaller offers, shop lighting and signage,” says Andreas Vogler, product manager SSL at Osram Opto. “This new LED extends our portfolio in the low-power range,” he adds.

Osram Opto claims that DURIS E 3 offers everything that is needed for uniform light. Its small size of 3mm x 1.4mm means that they can be placed very close to each other. Its beam angle of 120° ensures that in closely packed arrays the light from each LED overlaps that from its neighbor, yielding an extremely uniform distribution of light. Individual points of light can no longer be seen; instead, the impression is of a single bright strip of light.

The LED covers the entire white color spectrum with color temperatures from 3000K to 6500K. At a color temperature of 5000K, for example, it offers a color rendering index (CRI) of 72 and an efficiency of about 110lm/W, suiting use in industrial applications.

This summer, Osram Opto will debut the next member in the new family of low-power LEDs (the DURIS E 5, providing a high luminous flux and package dimensions of 5.6mm x 3mm).
