High-power white LED

4 September 2013 Opto-Electronics

The high-power Soleriq LED family from OSRAM Opto Semiconductors has a new member in the form of the S 13, boasting high brightness from a light emitting surface measuring just 13,5 mm in diameter and available in all colour temperatures.

This LED is designed for use in luminaires subject to high performance requirements. In hotel and restaurant, as well as shop and luxury residential lighting, it can be used to replace high-wattage halogen spotlights. The LED boasts a brightness of 1500 lm.

Like the E 30 and E 45, the Soleriq S 13 simplifies luminaire design since, thanks to its brightness, only one component needs to be installed in a luminaire instead of several. The individual chips are very closely arranged and all located under a conversion layer (chip-on-board), giving the impression of an homogeneous light emitting surface and ensuring a uniform colour and light appearance.

For even better homogeneity, the chips are arranged in a circle under the conversion layer. This greatly simplifies the coupling of the LEDs into external, light-guiding optics. The light generated can be used with much lower optical losses, which in turn makes the LED lamps and luminaires more efficient.

Unlike other commercially available high-power LEDs, no SMT soldering is necessary to mount the Soleriq S 13; glue, screws or solderless connector are sufficient.
