2.1.2 Optical System Connections (Optical Engine)
The optical system consists of 5 blocks: the lamp inner housing, light guide unit, optical
head/prism unit, and projector lens unit, which are shown below, and the driver board.
These units are specified as the optical engine, which is one replaceable part. In addition
to these five items, the FC board is attached at the bottom of the light guide unit. The relay
board connects the FC board in the lamp inner housing to the driver board. It is
independent of the optical functions.
