Compact multi-chip LED for interior lighting

The DURIS S 8 for directional retrofits offers maximum light from a small surface area

OSRAM Opto Semiconductors today announced the DURIS S 8, a new multi-chip, high-power member of the DURIS S LED series. The close grouping of the LED die allows for good color consistency in combination with a high luminous flux. The new DURIS S 8 is targeted for use in directional and omnidirectional retrofit lamps,  and spotlights and downlights used in interior lighting. It is ideal for directional lighting in office and business applications, as well as in the home.

DURIS S 8The color consistency, also known as color binning, in directional retrofits is achieved through the close grouping of the LEDs, which corresponds to the coverage of a five-step MacAdam ellipse. Three-step MacAdam grouping is also available for applications that require high 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,” said Marc Dyble, Product Marketing Manager for SSL at OSRAM Opto Semiconductors.

The new DURIS S 8 emits a great deal of light from a small surface area, creating efficient optical solutions. It measures just 5.8 x 5.2 mm and is available in six- or eight-chip versions. Thanks to the luminous flux of 500 lm at 200 mA, even the eight-chip version can be used in directional retrofits. “Compact, low-cost driver modules are available on the market for forward voltages between 20 and 30 V. Their technical characteristics, such as a longer service life of 25,000 hours and operating temperatures of 110 °C, are perfectly tailored to the target applications,” said Dyble.

The DURIS S 8 can also reduce the costs of lighting systems. The package consists of an innovative plastic housing material that is not only resistant to aging due to high temperature and short wavelength (UV) light, but also costs less than the ceramic housings frequently used.
