Abstract

A multi-view architectural lighting (MVAL) system includes one or more multi-view lighting units (“MV lights”) in which the apparent brightness and color of each MV light is individually and simultaneously controllable for different viewing angles. The MV lights can be pointed in arbitrary directions and installed in arbitrary locations in 3D space with respect to one another, consistent with the structure of a building, etc. This enables a lighting designer to create differentiated lighting experiences for different viewers based on their viewing angle with respect to the MV lights. A calibration system maps viewing locations to emitted light directions for each MV light. Using this information, the appearance of each MV light from a given viewing location relative to that MV light is set by adjusting the light (e.g., typically color and intensity, etc.) emitted in the corresponding direction/directions.

Claims26

Dependent claims

A multi-view architectural lighting system comprising:

a controller;
and
a plurality of multi-view lights that are controlled by the controller, wherein:
(A) each multi-view light consists of a single multi-view pixel, wherein the multi-view pixel is capable of generating a plurality of beamlets, each of which has a different emission direction from other of the beamlets of the plurality;
(B) a placement of each multi-view light with respect to a placement of each other multi-view light is not constrained to a plane or otherwise limited;
(C) at least some beamlets of the plurality thereof are selectively generated and emitted under the control of the controller so that, simultaneously and from the same plurality of multi-view lights:
(i) a first lighting pattern generated by at least some of the selectively generated beamlets is perceivable at a first viewing zone of a viewing region;
(ii) one of either:
(a) a second lighting pattern generated by at least some other of the selectively generated beamlets is perceivable at a second viewing zone of the viewing region;
or
(b) no lighting pattern is perceivable at the second viewing zone because beamlets having an emission direction for causing a lighting pattern to be perceivable in the second viewing zone are not generated;
(iii) the first viewing zone and the second viewing zone have a different viewing angle from one another with respect to the multi-view lights;
and
(iv) the second lighting pattern is not perceivable at the first viewing zone and the first lighting pattern is not perceivable at the second viewing zone.
