LED from Osram shines with 1,500lm

Osram Opto Semiconductors has released another member of its high-power Soleriq LED family that the company said provides outstanding basic lighting, particularly in the professional sector, thanks to its brightness of 1,500lm and a light-emitting surface of 13.5mm. The Soleriq S 13, available in all colour temperatures, is also designed for luminaires subject to high performance requirements.

The device, installed in LED luminaires or lamps as a so-called retrofit, aims to replace halogen spotlights with high wattages. Like the E 30 and E 45, the Soleriq S 13 greatly simplifies luminaire design because 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 a 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. Typical LED benefits, such as high energy efficiency, long lamp life and the associated minimal maintenance costs, also are evident in downlights fitted with a Soleriq S 13.

This high-power light source is relatively simple to work with. Unlike other commercially available high-power LEDs, no SMT soldering is necessary to mount the Soleriq S 13; glue, screws or solderless connector do the job, added the firm. Although the connecting wires can still be joined by simple manual soldering, and then glued or screwed to the heat sink, the simpler option by far is to use a solderless connector that takes care of both the electrical contact and mechanical mounting. It eliminates the need for soldering; the connecting wires need only be inserted in the terminals provided.
