Osram unveiled the prototype of its 1 mm x 1mm LED designed to be used in spotlights for retail lighting where exceptionally compact LEDs with high light output are needed to bathe articles on display in a particularly attractive light.
The Oslon Pure 1010 gives lighting designers a high degree of flexibility because of its extremely compact 1.0 mm x 1.0 mm x 0.25 mm dimensions.
The new LED features a typical luminous flux of 100 lm at 350 mA and a color temperature of 3,000 K almost perfectly follows Lambert’s law and 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 jeweler’s shop, for example.
What’s noteworthy is that the LED gives lighting designers a high degree of flexibility because of its extremely compact 1.0 mm x 1.0 mm x 0.25 mm dimensions. It comes without a primary lens. The reduction in height is due to CSP 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, explained Osram.
If applications call for highly concentrated spotlighting, customers can simply add appropriate secondary optics. The compact dimensions and directional emission of the LED allow the secondary optics to also be very small, which in turn means that the overall solution will save even more space and cost.
