Osram Ostar Projection Power family

With the Ostar Projection Power family, Osram has achieved projector brightness levels beyond the 3000 ANSI lumen barrier using LEDs instead of conventional lamps, making them accessible to a broad market.

Depending on the ambient light conditions and the distance to the projection surface, requirements differ for the light source. Osram offers three different power classes for RGB solutions in deep blue (440 nm), blue (456 nm), converted green (520 nm) and amber (614 nm). In the lowest power class, two chips of the same colour per component provide projector brightness of up to 1500 ANSI lm. In the mid-power class, four chips of the same colour per component can achieve 2500 ANSI lm. In the highest power class, six chips of the same colour per LED can achieve more than 3000 ANSI lm. The family thus offers an alternative to the high-pressure discharge lamps previously used in projectors above 2000 ANSI lm.

The developers at Osram have modified the individual LED chips, allowing them to be electrically connected in a series on the copper board. The system designer thus benefits not only from a lower operating current (with the same power consumption) and reduced complexity of the LED driver, but also from the simpler contacting of the component. In addition, direct coupling of the LEDs to a heat sink is possible.

The mechanical design remains largely unchanged compared to previous products, enabling a fast and uncomplicated exchange of the products in existing projector systems. Users can easily integrate the latest components in their desired power class into their system design.
