Abstract
An optical system includes a light source, a lens, and a light effect ring. The lens has first and second surfaces and receives a first light beam from the light source at the first surface and emits a second light beam from the second surface. The light effect ring includes a first plurality of light emitters emitting second light beams that obliquely illuminate the first surface of the lens and a second plurality of emitters that emit third light beams through the lens. The light effect ring may include a plurality of segments that move into and out of the first light beam, where each segment includes a first subset of the first plurality of light emitters and a second subset of the second plurality of emitters.
