Compact individual LED is an alternative to low-lumen Chip-on-Board LEDs
DURIS S 10 is the latest addition to the Chip Array SMD family (CAS) from OSRAM Opto Semiconductors. This new LED is characterized by high efficiency, high light output and uniform color appearance. Efficient surface mounted device (SMD) technology makes assembly simple and leads to significant cost savings in system and optic designs of up to 30 percent, depending on the particular application. The DURIS S 10 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.
“With typical luminous flux packages of 1050 and 1400 lumens and a light-emitting surface of only 7.7 mm in diameter, the new DURIS S 10 forms the basis for compact optics and extremely narrow beam angles,” explained Marc Dyble, Marketing & Business Development Manager for General Lighting at OSRAM Opto Semiconductors.
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 – a clear advantage over the frequently used multi-LED clusters. Both single-spot versions have the same footprint of 7.0 mm x 7.0 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 is easier to integrate standard accessories, such as lenses and reflectors.
Both DURIS S 10 CAS LEDs are binned according to the familiar MacAdam ellipses, resulting in a more uniform color 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. In standard Chip-on-Board (CoB) solutions, these functions needed to be accommodated on a separate PCB, taking up more space. Compared to these established solutions, the two new DURIS S 10 LEDs are excellent alternatives in this luminous flux category.
