Abstract
A method of monitoring an illumination source including a reflector and a lamp. A reference orientation is defined where the reflector and a light producing luminary of the lamp are aligned to optimize light intensity reflected from the luminary to a desired target. The orientation of the lamp is monitored, and changes from the reference orientation are reported as an indication of a reduction in light intensity reflected from the luminary toward the desired target.
