Abstract
Self-aligning mechanisms hold a condenser housing. The condenser housing is moved toward an integrator while tapered surfaces of the condenser housing of an LED light source unit are inserted along condenser lens guides of a projection unit. LED light source unit datum surfaces and datum surfaces of the projection unit abut against each other, and the tapered surfaces of the LED light source unit can no longer move toward the integrator along the condenser lens guides of the projection unit. In this state, the LED light source unit and the projection unit are coupled to each other.
