Architectural lighting distributed from contained radially collimated light

A light distribution means comprising first and second collimation optics each containing a separate quasi point source, a containment optics for limiting axial dispersion of light from said first and second collimation optics, and distribution optics receiving light from both said first and second collimation optics, whereby light from both sources may be mixed and distributed in a distribution pattern of the light distribution optics.

Light distribution means consisting of a downlight comprising segmented collimation optics having an axial extent in an axial degree of freedom, said collimation optics comprising means for providing radially collimated and lineally collimated light from a quasi point source , containment means for limiting axial dispersion of collimated light with respect to distance from the source, and distribution optics substantially contained within the axial extent of said collimation optics and receiving both the radially collimated and lineally collimated light and directing the beams to provide a combination of beams, whereby a preselected combination of light patterns for surface illumination and wall washing is provided.

In a light distribution means for distributing and shaping light from a quasi point source comprising:

• radial collimation optics surrounding said quasi point source over a preselected angular extent around an axis, said collimation optics including entrance aperture means extending in an axial direction for intercepting light from said source and distribution optics located radially outwardly of said collimation optics for intercepting light directed within a radial degree of freedom, said distribution optics being shaped to provide a selected light distribution pattern, the improvement wherein said collimation optics is divided into segments each subtending a selected arc of a circle surrounding said quasi point source.

Light distribution means for distributing and shaping light from a quasi-point source comprising:

• radial collimation optics surrounding said quasi point source over a preselected angular extent around an axis, said collimation optics including entrance aperture means extending in an axial direction for intercepting light from said source, and distribution optics located radially outwardly of said collimation optics for intercepting light directed within a radial degree of freedom, said collimation and said distribution optics being formed to contain substantially all light from the source in a segment of a radial plane and wherein the distribution optics comprising first reflector which is parabolic in the radial plane and wherein the source is at a focus of the parabolic in the radial plane and wherein the source is at a focus of the parabola, said reflector having a dimension in an axial degree of freedom substantially corresponding to that of said collimation optics, and wherein said reflector is formed to capture substantially all radiating from said collimation means in an arc subtended by said reflector.
