METHODS AND DEVICES FOR PROJECTION OF LIGHTING EFFECTS CARRYING INFORMATION
First Claim
1. A lighting fixture, comprising:
- A housing;
least two light-emitting diodes (LEDs) contained on or within the housing and configured to project at least two spatially-limited lighting effects on one or more surfaces;
a controller contained within the housing and operably coupled to the at least two LEDs and configured to selectively energize the at least two LEDs to cause the at least two projected lighting effects to carry at least two distinct coded light signals simultaneously, wherein at least one of the at least two projected lighting effects carries a coded light signal.

Abstract
Methods, apparatus, and systems are disclosed herein for projecting lighting effects (124, 224, 324, 424) carrying light messages onto surfaces. A first of one or more light-emitting diodes (LEDs, 554) of a lighting fixture (120, 220, 320, 420, 520) may be selectively energized to produce a first coded light signal conveying a first light message associable with a first location. Light emitted from the first LED may be projected onto a first surface, e.g., as a spatially-limited lighting effect. In some embodiments, a second of the one or more LEDs of the lighting fixture may be selectively energized to produce a second coded light signal conveying a second light message associable with a second location distinct from the first location. Light emitted from the second LED may be projected onto the first surface or a second surface. Alternatively, lighting effects of various shapes and hues may convey information.

16. A method, comprising:
-
selectively energizing, by a controller of a lighting fixture, a first of a plurality of light-emitting diodes (LEDs) of the lighting fixture to produce a first coded light signal that conveys a first light message associable with a first location; projecting, by the lighting fixture, light emitted from the first LED onto a first surface; selectively energizing, by the controller, a second of the plurality of LEDs of the lighting fixture to produce a second coded light signal that conveys a second light message associable with a second location distinct from the first location; and projecting, by the lighting fixture, light emitted from the second LED onto the first surface or a second surface. - View Dependent Claims (17, 18, 19, 20)

21. A lighting comprising:
-
a housing; first and second light-emitting diode (LEDs) contained within the housing; first and second optical elements mounted on the housing and configured to direct light emitted from the first and second LEDs onto one or more surfaces; and a controller operably coupled to the first and second LEDs and configured to; illuminate the first LED to produce a first coded light signal that conveys a first light message associable with a first location; and illuminate the second LED to produce a second coded light signal that conveys a second light message associable with a second location distinct from the first location. - View Dependent Claims (22, 23)
