LED driver for LED front projector

- File#1 OSRAM_LED_front_projector.bmp (84.4 KB) , download : 1 Driver technology from OSRAM i ( http:// ) is integrated into the first full HD home cinema projector with an LED lighting system. RAPCUR10 LED drivers enable LED front projectors to produce razor-sharp images of unparalleled quality.

With a resolution of 1,080p (1,920 x 1,080 pixels), a light intensity of more than 500 lumens on the projection surface and an extensive color scale, the full HD LED projector produces a far higher image quality than traditional devices thanks to the RAPCUR10 LED Driver from OSRAM.

Moreover, the shock-resistant LEDs have a lifespan of more than 25,000 hours which means that the usual change of light sources in the projector can be dispensed with.

The driver has three channels (for red, green and blue) and works in real time in the projector to process the complex control signals responsible for the exact control of the LEDs and thus for the high image quality.

For the first time, OSRAM is using an FPGA (Field Programmable Gate Array) which facilitates exceptionally fast and accurate signal processing. The high LED currents of up to 30A and the very short switching constraints demand high switching speeds.

The RAPCUR10 driver facilitates switch-on and switch-off times of less than 1μs with currents of 30A. The LED driver can also supply 255 gradations of current. It is a perfect solution for numerous projection applications such as front and rear projectors, video wall And special projectors.
