Colour LEDs for architectural lighting

15 May 2013 Opto-Electronics

OSRAM Opto Semiconductors is now offering the mid-power LED Duris P 5 in colour. The five new variants are ideal for architecture lighting and for the hospitality sector.

The five colour versions of Duris P 5 are deep blue (450 nm), blue (470 nm), true green (528 nm), yellow (590 nm) and red (615 to 625 nm). At the heart of the different colours are state-of-the-art chip technologies based on either the InGaN (Indium Gallium Nitrite) material system or InGaAlP (Indium Gallium Aluminium Phosphite) depending on the wavelength.

Low forward voltages and optimised light extraction result in high luminous efficacies for all types. The deep blue version, for example, delivers a light output of 140 mW (at 100 mA and 25°C), corresponding to a typical efficiency of 48%.

As members of the mid-power class, the colour versions of Duris P 5 are ideal for linear, area or omnidirectional lighting applications in which the light has to be distributed as uniformly as possible. Colour mixing is also possible for applications involving several colours.
