DURIS E 3: Small footprint with high power

DURIS E 3 OSRAM LED ApplicationCost-effective LED for linear tubes

OSRAM Opto Semiconductors is presenting a new version of the well-established DURIS product family: the DURIS E 3 (GW JCLMS1.EC). Featuring a new leadframe material, the LED offers a longer lifetime and greater performance reliability than its predecessors. In linear tube lighting applications, the new DURIS E version boasts a high efficacy of typically 135 lm/W at 4000 K and 65 mA as well as one of the best lumen/cost ratios in the series.

The package of the new DURIS E 3 is made from a special PCT leadframe material that permits a longer lifetime and higher performance reliability than the PPA material used in the current DURIS E 3 version (LxW JNSH.EC). As a result, it achieves the best brightness level per dollar (lm/$) within the DURIS E series. Furthermore, the new LED has a high efficacy of typically 135 lm/W at 4000 K. The new DURIS E 3 offers a range of lumen packages from 25 lumens (lm) to 30 lm, which can optimally be used in linear tube light applications. Integrated in these lighting solutions, the number of LEDs can be minimized and the so-called hot-spot effect can be avoided. The DURIS E 3’s thermal resistance is typ. 41 K/W.

With a beam angle of 110°, the DURIS E 3 is ideal for homogenous and uniform light distribution. Another advantage is the small footprint of 3.0 mm x 1.4 mm, a competitive value by industry standards. With its excellent color uniformity, stability and a good color rendering of min. 80, the new LED is particularly suitable for interior lighting applications like linear, troffer or panel lights, retrofits – especially fluorescent replacement lamps – downlights and fixtures. The new DURIS E 3 will be available in seven different color temperatures from 2700 to 6500 Kelvin (K) by mid-February 2015.
