At the Light+Building 2018 show in Frankfurt, Germany (18-23 March), Osram Opto Semiconductors GmbH of Regensburg, Germany has unveiled the prototype of the Oslon Pure 1010 LED, targeted at use in spotlights for retail lighting (where exceptionally 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 enables flexibility in putting together individual lighting solutions.
Osram says that, with typical luminous flux of 100lm at a drive current of 350mA and a color temperature of 3000K, the prototype almost perfectly follows Lambert’s law and achieves a flux density of 237lm/mm² when operating at 1000mA. The achieved luminance is then much higher for the same component size. This property is useful particularly if the new LED is used for illuminating merchandise in retail outlets.
Because of its compact 1.0mm x 1.0mm x 0.25mm dimensions, the Oslon Pure 1010 gives lighting designers a high degree of flexibility. The new LED comes without a primary lens, and the reduction in height is due to the chip-scale package. 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, so 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, appropriate secondary optics can simply be added. Due 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, Osram Opto unveiled the prototype of the Oslon Pure 1010 in the CRI-80 version. The LED will be available as early as May. A CRI-90 version will then follow in fall 2018.
