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.
Claims26
A mount assembly comprising:
- a mount;
- a motor movably attached to the mount;
- a color wheel fixedly attached to the motor, the color wheel having a spiral color filter with a filter edge;
- a light integrator rod having an input face and an output face proximate to the color wheel;
- and
- an alignment mechanism configured to move the motor with respect to the light integrator rod in a first direction and in a second direction to align the filter edge with respect to the output face of the light integrator rod.
A mount assembly comprising:
- a mount;
- a motor;
- a color wheel fixedly attached to the motor, the color wheel having a spiral color filter with a filter edge;
- a light integrator rod having an input face and an output face proximate to the color wheel;
- a cover extending along the integrator rod from the input face toward the output face;
- and
- a plate attached to the input face of the light integrator rod supporting the light integrator rod in a cantilever fashion within the cover and sealing a first end of the cover from dust intrusion.
A method of aligning a scrolling color light system comprising:
- adjustably attaching a motor mount having a motor with a scrolling color wheel to a light integrator mount supporting a light rod;
- aligning the light rod to an optical axis of a light source;
- and
- aligning an output face of the light rod to the scrolling color wheel without changing the alignment of the light rod with respect to the optical axis of the light source.
