Abstract
An image projection lighting device is provided which includes a variable homogenizing system. The variable homogenizing system may homogenize light projected by a lamp across a light valve. The variable homogenizing system may vary the light across the light valve from an existing state to a first state or from an existing state to a second state. The variable homogenizing system may be comprised of one or more lens arrays, which may be comprised of cylindrical or spherical lenses.

A stage lighting apparatus comprising
- an image projection lighting device comprising:
- a base;
- a lamp housing;
- wherein the lamp housing is remotely positioned in relation to the base by a motor;
- the lamp housing comprising
- a lamp;
- and a first light valve;
- and a variable homogenizing system;
- wherein the lamp creates a first light that is directed toward the variable homogenizing system;
- and wherein the variable homogenizing system homogenizes the first light to create a second light.
