Osram Unveils LED For Retail Lighting

Chip scale package prototype delivers highest flux density for retail spotlights

Osram Opto Semiconductors has unveiled the prototype of the Oslon Pure 1010 at this year's Light+Building in Frankfurt. Sized at 1 mm x 1mm, the LED is destined to be used in spotlights for retail lighting where compact LEDs with high light output are needed to bathe articles on display in an attractive light.

The scalability of the chip scale package (CSP) LED gives customers flexibility in putting together their individual lighting solutions, according to the company.

The prototype of the new Oslon Pure 1010 with its typical luminous flux of 100 lm at 350 mA and a colour temperature of 3,000 K achieves a flux density of 237 lm/mm² when operating at 1,000 mA. The achieved luminance is then very much higher for the same component size. This property is useful particularly if the new LED is used for illuminating merchandise in retail outlets "“ diamond rings in a jeweller's shop, for example.

The Oslon Pure 1010 gives lighting designers a high degree of flexibility because of its compact 1.0 mm x 1.0 mm x 0.25 mm dimensions. The new LED comes without a primary lens.

The reduction in height is thanks to the chip scale package (CSP). The light-emitting surface is contacted not in the usual way with a bond wire from above but within the component itself without the need for bond wires.

These properties together with the small dimensions enable multiple LEDs to be placed very close together in a small space. Warm white and cold white LEDs can be combined "“ the number of individual LEDs, their arrangement and the relative proportions of warm white and cold white LEDs can be tailored to meet specific customer requirements.

If applications call for highly concentrated spotlighting, customers can simply add appropriate secondary optics. Thanks to the compact dimensions and directional emission of the Oslon Pure, the secondary optics can also be very small, which in turn means that the overall solution will save even more space and cost.

At Light+Building 2018 (March 18 through 23), Osram is unveiling the prototype of the Oslon Pure 1010 in the CRI-80 version. The LED will be available as early as May 2018. A CRI-90 version will then follow in the fall of 2018.
