This is a data brief about the OSRAM OSTAR projection LED board. The board features outstanding brightness and luminance, suitable for additional optics. It includes red, green, and blue LEDs with a light emitting surface of 2.1 x 2.1 mm2. The luminance of the red LED is 18*106 cd/m2, the luminance of the green LED is 14*106 cd/m2, and the luminance of the blue LED is 3.5*106 cd/m2. The green LED has an efficacy of 86.0 lm/W, and the blue LED has an efficacy of 17.0 lm/W.
This document describes the STEVAL-ILLOO9V3, an evaluation board designed for the OSRAM OSTAR® projection LED. The board integrates a single package containing red, green, and blue LEDs to create superior color effects compared to separate components. It is intended to be connected via a 30-pin connector to the STEVAL-ILLOO9V1 control board to demonstrate light effects.
