OsramOpto Semiconductor has recently released the Oslon Square family – its first 2mm² LED family, which generates 2 times more light than the Oslon SSL 1mm² chip. The new design of cathode and anode increases the light extraction of the LED. Moreover, the efficacy of the chip is enhanced by the new package design improving reflection. The blue Oslon Square produces 270lm for 700mA, i.e. 123lm/W.

Manufactured in the new Osram UX:3 technology, the 2 components integrate a thin GaN LED bonded on a germanium substrate and a silicon protective diode in a tiny ceramic package (3mm x 3mm).

System Plus Consulting recently published a reverse costing report comparing OslonSquare 2mm² with Oslon SSL 1mm²: 2 blue LEDs from OSRAM.

This report provides a complete teardown of the 2 LEDs with:
