Duris is Osram's primary mid-power LED offering comprising a number of form factors with the LEDs embedded in plastic packages. The company announced the family with the launch of the Duris E 3 LED family for linear applications back in 2011. The company subsequently launched the larger Duris E 5 LED for retrofit lamp applications. The near-square Duris S 5 family measures 3.2×3 mm, and targets a variety of lamp and luminaire applications.
Previously, the Duris S 5 LEDs featured a maximum CRI of 80. Indeed, most mid-power LEDs in the industry have maxed out at that level of color rendition, which is generally accepted as sufficient for residential lighting and many commercial and industrial applications.
Bumping the CRI to 90, however, will expand the Duris market. "This product family now offers customers even greater flexibility in terms of performance, areas of application and technology than ever before," said Marc Dyble, product marketing manager for general illumination at Osram.
Specifically, Osram said the new LEDs will offer benefits such as making wood surfaces look more natural and appealing. Moreover, high CRI is important in rendering skin tones, clothing, and food.
