Chip scale package LED from Osram takes retail lighting to another level

The prototype of the new Oslon Pure 1010 with its 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.

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 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.
