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, the light source mounted on a wall of the mixing chamber at a location that does not cause light emitted from the light source to directly exit the apertures but causes reflection and scattering of the emitted light within the mixing chamber before passing through an aperture of the array; and
an array of lenses 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 lenses and at least an effective edge of the array of apertures are relatively displaceable parallel to said one wall;
wherein the array of lenses are configured to steer a direction of the beam based on the relative displacement.

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.

10. A luminaire comprising:
-
a mixing chamber having an array of fixed apertures in one wall; a light source to supply light into the mixing chamber, the light source mounted on a wall of the mixing chamber at a location that does not cause light emitted from the light source to directly exit the apertures but causes reflection and scattering of the emitted light within the mixing chamber before passing through an aperture of the array; and an array of optics outside the mixing chamber, each positioned to cooperate with a respective one of the fixed apertures to emit light from the mixing chamber as a beam; and wherein at least one of said array of fixed apertures and said array of optics are non-uniform such that different pairs of an optic and its respective fixed 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. - View Dependent Claims (14)

11. A luminaire comprising:
-
a mixing chamber having an array of apertures in one wall; a light source to supply light into the mixing chamber, the light source mounted on a wall of the mixing chamber at a location that does not cause light emitted from the light source to directly exit the apertures but causes reflection and scattering of the emitted light within the mixing chamber before passing through an aperture of the array; 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 an external surface of said one wall bears a pattern or design that is visible through said array of optics at least when said luminaire is not illuminated. - View Dependent Claims (12, 13)
