10. LIGHT PROCESSOR + LIGHT PIPE ASSEMBLY
About this chapter
This chapter describes briefly the functionality of the light processor and light pipe and the procedures which must be followed to
replace this unit.
Functionality
The light processor and light pipe have three major parts, namely:
• The light processor. The prism of the light processor first splits up the homogeneous white light coming from the light
pipe into
red, green and blue light. Then integrates the video information on the three DMD’s with the red green and blue light beams.
Next, 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.
• The Formatting Interface Board (FIB), which is the interface between the Pixel Mapping Processor (PMP) and the Formatting
boards of the DMD’s.
• The light pipe, which transforms the light emitted by the lamp into a homogeneous light beam and f
ocuses this beam precisely
on the active surface of the DMD’s.
Note that the light processor and light pipe assembly includes: Light processor, light pipe, cooling circuit for the DMD’s and light pipe
entrance, integration rod, Formatter Interface Board (FIB), motorized shutter and motorized contrast enhancement.
