Osram releases a 13.5-mm COB LED for halogen spotlight retrofits

The Soleriq S 13 shines over a small illuminated surface with a brightness of 1,500 lm

The high-power Soleriq LED family from Osram Opto Semiconductors has a new member: The Soleriq S 13 boasts high brightness from a light-emitting surface measuring just 13.5 mm in diameter and is available in all color temperatures. This Soleriq LED is also designed for use in luminaires subject to high performance requirements. In hotel and restaurant, as well as shop and luxury residential lighting, the Soleriq S 13 – installed in LED luminaires or lamps – replaces high-wattage halogen spotlights.

The new Soleriq S 13 provides outstanding basic lighting, particularly in the professional sector, thanks to its brightness of 1,500 lm and a light-emitting surface of 13.5 mm. Installed in LED luminaires or lamps as a so-called retrofit, it replaces halogen spotlights with high wattages. “The Soleriq S 13 is predestined for the hospitality and home lighting sector, because in addition to its high brightness, it covers all color temperatures. What is more, the color rendering index for all color temperatures is over 80. As a result, the S 13 significantly expands the application portfolio of the Soleriq LED family, whose existing E 30 and E 45 versions previously were designed for downlights,” explains Andreas Vogler, Product Manager in Marketing SSL responsible for the Soleriq LED family at Osram Opto Semiconductors.

Uniform colour and light appearance

Like the E 30 and E 45, the Soleriq S 13 greatly simplifies luminaire design, because thanks to its excellent 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 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.

Simple installation with no SMT soldering (Surface Mount Technology)

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. 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.

* The Zhaga Consortium was established to define standards for LED modules. It gives consideration to mechanical, thermal, photometric and electrical interface parameters. With these defined standards, Zhaga-certified light engines will become the counterpart to standardized light sources in traditional lighting, such as incandescent or fluorescent lamps.
