High-power LED for lighting

22 July 2015 Opto-Electronics

Duris S 10, the latest addition to the chip array SMD (CAS) family from OSRAM Opto Semiconductors, is characterised by high efficiency, high light output and uniform colour appearance.

Efficient surface mounted device (SMD) technology makes assembly simple and leads to cost savings of up to 30% in system and optic designs, depending on the particular application. The LED has a compact footprint and is available in two output classes of up to 1400 lumens, simplifying the design of lamps and luminaires, and is ideal for use in spotlights, down lights, directional and omnidirectional retrofits.

The lumen packages were chosen specifically for standard applications, such as MR16 retrofits, and enable the creation of lamp and luminaire designs on the basis of a single Duris S 10. This helps prevent multiple shadow effects – an advantage over frequently used multi-LED clusters.

Both single-spot versions have the same footprint of 7 x 7 mm, offering flexibility in the design of compact luminaires with high luminous flux. The small size of the LED and simplified design of the optics makes it easier to integrate standard accessories such as lenses and reflectors.

These new CAS parts are binned according to the familiar MacAdam ellipses, resulting in a uniform colour appearance. In view of the surface-mounted design of the LED, a printed circuit board (PCB) must be incorporated in the luminaire. This opens up numerous design options such as integrating thermal fuses, connectors or driver components on the LED board.
