Osram Opto Semiconductors GmbH of Regensurg, Germany has added to its Duris S 5 family of LEDs with two further models with color rendering index of more than 90, suitable for the home (e.g. installed in downlights or LED retrofit lamps).
The one-chip version of the new Duris S 5 (GW PSLMS1.CC) has luminous flux of 20.5lm at 65mA (typically at 3000K). Typical forward voltage is 2.9V. The two-chip version (GW PSLPS1.CC) has high luminous flux of 83lm at 150mA (typically at 3000K). Typical forward voltage is 6.35V. The package size for both is 3.2mm x 3mm.
“This product family now offers customers even greater flexibility in terms of performance, areas of application and technology,” says Janick Ihringer, product manager for General Illumination. The previous Duris S 5 versions already had a high color rendering index of more than 80. The new 90-CRI LEDs are suitable particularly for applications where the colors have to appear as natural as possible. Their main use will therefore be in the home. For example, light from the new Duris S 5 models make the colors of wooden dining tables and flooring look rich and natural, says Osram. Natural color rendering also plays an important role in shop lighting, whether for clothing or food.
The new LEDs are part of the Duris product family. The E, P and S series contain LED versions in different qualities of light and for all output ranges (high-power, mid-power and low-power) suitable for numerous lighting applications. A robust plastic package, a compact design and a particularly homogeneous distribution of light are other properties common to all members of the family, says Osram.
