OSRAM Introduces a CSP LED Prototype, Targeting Retail Lighting with High Throughput Density

At the 2018 Lighting Fair in Frankfurt, Germany, OSRAM Opto Semiconductors introduced the prototype of the Oslon Pure 1010 LED, targeting spotlights for retail lighting. The scalability of chip-scale package (CSP) LEDs allows them to flexibly combine lighting solutions.


OSRAM said that Oslon Pure 1010 LED's typical luminous flux is 100lm, the driving current is 350mA, and the color temperature is 3000K. It almost perfectly follows Lambert's law and the flux density reaches 237lm/mm2 when the current is 1000mA. For the same component size, this prototype achieves a much higher brightness and is particularly suitable for lighting items in retail stores.

With a compact 1.0mm x 1.0mm x 0.25mm size without the main lens, the Oslon Pure 1010 offers lighting designers a high degree of flexibility. Thanks to the CSP package, the height is reduced. The light emitting surface is not in contact in the usual manner but is in contact within the component itself, no bonding wire is required. These characteristics, together with the small size, allow the arrangement of multiple LEDs in close proximity in a narrow space. Warm white and cool white LEDs can be used in combination, so the number of individual LEDs, their arrangement, and the relative proportions of warm white and cool white LEDs can be tailored to specific customer requirements.

If you are using a highly concentrated spotlight, you can simply add the appropriate secondary optics. Thanks to Oslon Pure's compact size and directional luminescence, the secondary optics can also be very small, which means that the entire solution saves more space and costs.

The prototype exhibited at the show was the CRI-80 version, which was first listed in May. The CRI-90 version will be available this fall.
