Osram Opto to Debut Highest Flux Density Chip Scale Package LED at Light + Building

Osram Opto Semiconductors Oslon 1010 CSP LED prototype

At this year’s Light + Building in Frankfurt, Germany, Osram Opto Semiconductors is debuting the prototype of the Oslon Pure 1010. The chip scale package LED measuring just 1 mm by 1 mm boasts a flux density of 237 lm/mm² when operating at 1,000 mA. The company created the LED for applications such as retail spotlights where exceptionally compact LEDs with high light output are required to bathe items on display in an attractive light.

The prototype of the new Oslon Pure 1010 features a typical luminous flux of 100 lm at 350 mA and a color temperature of 3,000 K. The company claims that the CSP LED almost perfectly follows Lambert’s law to achieve its unprecedented flux density. This obtained luminance is then very much higher than any other component with the same size, making the LED particularly useful in illuminating wares at retail shops

The scalability of the chip scale package (CSP) LED gives customers outstanding flexibility in putting together their individual lighting solutions. The Oslon Pure 1010 is also just 0.25 mm thick and comes without a primary lens. The chip scale package enables the reduction in height.

Oslon Pure 1010 Contacted Without Wire Bonds

According to the company, the light-emitting surface is contacted not in a typical way with a bond wire from above but within the component itself without needing bond wires. So, multiple Oslon Pure 1010 LEDs can be positioned close together in a small space. Also, warm white and cold white LEDs can be combined into a single array. The number of individual LEDs in such an array, their arrangement, and the relative proportions of cold white and warm white LEDs can be customized to meet specific customer needs.

For applications calling for highly concentrated spotlights, customers can add suitable secondary optics. Due to the compact footprint and the directional emission of the Oslon Pure, the secondary optics can also be very small, which in turn allows the overall solution to save even more space, and the small size also reduces the total cost of materials.

At Light+Building 2018, Osram Opto Semiconductors will reveal the prototype of the Oslon Pure 1010 in the CRI-80 version for the first time in Hall 6.2, booth C04. The company plans to make the LED available as early as May 2018 and intends to bring a 90 CRI version to market in the fall of 2018.
