the chip with high efficiency resulting in high luminous intensity

The three independently controllable LED chips in blue, red and green in the MultiLED are available in different brightness groups thanks to finely defined grouping (known as binning). They can be individually combined to produce a large color spectrum. All three chip colors are the product led high bay of state-of-the-art technology: Blue and green in UX:3 technology, red in the latest thin-film technology. The light is therefore extracted from the chip with high efficiency resulting in high luminous intensity. In the upper blue wavelength range, for example, a figure of up to 560 millicandelas is achieved at an operating current of 20 mA. Luminous intensity in candela (cd) corresponds to luminous flux in lumen (lm) emitted by a light source in a particular solid angle. The typical thermal resistance between the chip and the solder point is 127 K/W for blue and green, and 96 K/W for red.

Osram Opto Semiconductors launches the Duris S 8, a new, multi-chip, high-power member of the Duris “S” LED series. The close grouping of the LED permits very good color consistency in combination with a high luminous flux. The new Duris S 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.

The very good color consistency (color binning) in the directional retrofits is achieved through the close grouping of the led high bay light, 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, as is customary. “In terms of color rendering, the Duris S 8 has a CRI of more than 80. An even higher CRI will be the next step,” says Janick Ihringer, the responsible Product Manager SSL at Osram Opto Semiconductors.
