9.1 Introduction Light Processor
Light Processor
The Light Processor is the heart of the projector. The prism of the Light Processor splits homogeneous white
light coming from the Light Pipe into red, green and blue light. The video information on the three DMD's is
converted to these red green and blue light beams. The prism merges the three integrated light beams back in
to one full color video image, which is projected via the lens onto the screen.
Each DMD has its own formatting board (satellite board) which drives the micro mirrors to convert the video
signal into the light beam. Heat is produced during the integration of the video information. To protect the
DMD's from overheating the Light Processor is cooled by several fans and four temperature sensors. Each
channel is equipped with its own dedicated fan, heatsink and temperature sensor to protect the Light
Processor for overheating.
Both the blue and the green channel DMD are equipped with three convergence adjustment knobs each. The
red channel DMD is fixed and serves as the reference channel for convergence alignment. Two of the three
adjustment knobs per channel (red/green) are extended for easier access.
All critical air-gabs are sealed. The DMD are also sealed.
At the bottom of the prism exit a
“
touch
”
sensor is mounted to protect the prism against accidental lens
movements.

Troubleshooting of the Light Processor
There are several potential reasons why removal or replacing of the Light Processor could be required.
Nevertheless, try to avoid unnecessary removal of the Light Processor. The list below gives an overview of the
