ABSTRACT:
A light integrator is mounted in a housing or cover that allows aligning the light integrator relative to a color wheel or other sequential color element. In some embodiments, a plate is attached to one end of a light rod and supports the light rod in the cover in a cantilever fashion or in combination with other support. The light rod is aligned to a light source, such as a lamp, and then the color wheel is aligned to the output of the light rod without altering the relationship between the light rod and the lamp.
