Abstract
A luminaire includes a light source configured to generate an emitted light beam and a diffusion wheel subsystem. The subsystem includes a first diffusion wheel to provide different degrees of diffusion to the light beam, and a second diffusion wheel stacked with the first diffusion wheel and to provide different degrees of diffusion to the light beam. A first diffusion region of the first diffusion wheel provides a lowest degree of diffusion, and the first diffusion region of the first diffusion wheel is located at a first edge of the first diffusion wheel. A first diffusion region of the second diffusion wheel provides a degree of diffusion approximately equal to that of the first diffusion region of the first diffusion wheel, and is located at a second edge of the second diffusion wheel.
