Osram adds high-power SMD LED
Osram Opto Semiconductors has added a new device to its Chip Array SMD family (CAS). Called DURIS S 10, the new LED is characterised by high efficiency, high light output and uniform colour appearance, according to the company.
In addition Osram says that 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.
"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 and 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 colour appearance. In view of the surface-mounted design of the LED, a printed circuit board must be incorporated in the luminaire. This opens up 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, says Osram.
The DURIS S 10 is suited for use in spotlights, down lights, directional and omnidirectional retrofits.
