Rutronik: compact multi-chip LED for interior lighting from Osram


Osram Opto Semiconductors extends its Duris “S” LED series by the Duris S 8. The new multi-chip, high-power LED offers lots of light from a small surface. It is primarily used in directional and omnidirectional retrofits, as well as in LED spots in indoor lighting. It is particularly suitable for directional lighting in office and business premises, as well as in the home. Rutronik distributes the new Duris S 8 in two versions as of now. The very good color consistency (color binning) in the directional retrofits is achieved through the close grouping of the LEDs, which corresponds to the coverage of a 5-step MacAdam ellipse. 3-step MacAdam grouping is additionally available for applications requiring very good color homogeneity. The Duris S 8 is grouped by color coordinates at the junction temperature of 100°C instead of at room temperature. In terms of color rendering, it has a CRI of more than 80. The new Duris S 8 measures only 5.8 × 5.2mm and is available in two versions: with six or eight chips. Version 1 (six chips) comes with a grouping current of 200mA, forward voltage of 18.6 up to 22.2V and a luminous flux of 390lm at typical 25°C and 3,000K.
