1. A luminaire comprising:
- a mixing chamber having an array of apertures in one wall;
a light source to supply light into the mixing chamber; and
an array of optics outside the mixing chamber, each positioned to cooperate with a respective one of the apertures to emit light from the mixing chamber as a beam; and
wherein the array of optics and at least an effective edge of the array of apertures are relatively displaceable parallel to said one wall.

Abstract
A luminaire includes a mixing chamber having an array of apertures in one wall, a light source to supply light into the mixing chamber, and an array of optics outside the mixing chamber, each positioned to cooperate with a respective one of the apertures to emit light from the mixing chamber as a beam. The shape, size, and/or direction of the output light beam are controllably varied by controlling the shape, size, and/or position of each aperture relative to its associated optic.

9. A luminaire comprising:
-
a mixing chamber having an array of apertures in one wall; a light source to supply light into the mixing chamber; and an array of optics outside the mixing chamber, each positioned to cooperate with a respective one of the apertures to emit light from the mixing chamber as a beam; and wherein at least one of said array of apertures and said array of optics are non-uniform such that different pairs of an optic and its respective aperture cooperate to produce beams of light that are different in at least one of shape and direction, said different beams combining to form an overall beam of a desired beam pattern.
