Osram Duris for Colour Mixing Applications

Dec 17 2015

For smart lighting solutions and all kinds of coloured lighting applications, the new Duris S 5 colour LEDs from Osram Opto Semiconductors are available in four colour versions — red, amber, green and deep blue — offering high efficacy and temperature stability. The footprint of 3.0 mm x 3.0 mm complies with industrial standards.

All red, amber, green and deep blue Duris S 5 colour versions can be used in colour mixing systems, as well as in combination with white LEDs. They are all based on the same chip technology using phosphor conversion to generate the saturated red, amber and green colours. Therefore, they all feature the same electrical behaviour and are compatible with the Duris S 5 White, which greatly simplifies driver design. In addition, the red and amber Duris S 5 versions are best in their class for lumen maintenance and temperature stability between 25° and 85° Celsius, reducing the complexity of colour management in different conditions.

The use of red and amber in combination with white LEDs can compensate for missing colours in the white spectrum, thereby increasing the colour rendering index (CRI) with rich Ra values. Further characteristics include an epoxy-based package and a footprint of 3.0 mm x 3.0 mm that complies with industrial standards.

The green colour versions offer an extremely high efficacy of 170 lm/W – a value which is three times higher than that of comparable standard green colour LEDs. This reduces assembly costs as customers need fewer Duris S 5 colour LEDs to achieve the same brightness level for their applications and can be more flexible in their PCB design. Brightness levels are high: 28 lm for red, 45 lm for amber, 170 lm for green and 420 mW for deep blue
