METHODS AND APPARATUS FOR CREATING DIRECTIONAL LIGHTING EFFECTS

摘要

Disclosed is a lighting fixture (10) that illuminates a presentation object or surface. The lighting fixture includes a first member (18) that at least partially surrounds or encompasses the presentation object and has a plurality of LED-based light sources (12) which can create a variety of lighting effects based on one or more characteristics of the presentation object. The lighting fixture further has a sensor (34) that detects a characteristic of the presentation object, and a controller (26) connected to the sensor such that, as a result of the individual addressability of the LED-based light sources, create or modify a directional lighting effect based on the detected characteristic.

主权项

1. A lighting fixture configured to illuminate an object, the lighting fixture comprising:
a first member comprising a plurality of LED-based light sources and defining a central region, wherein each of said plurality of LED-based light sources is individually addressable, and further wherein the plurality of LED-based light sources are configured to create one or more of a plurality of lighting effects, wherein the first member comprises a circular member and the plurality of LED-based light sources are disposed along the circular member; a sensor configured to determine a parameter of an object placed at least partially within the central region; and
a controller operably connected between said sensor and said plurality of individually addressable LED-based light sources, wherein said controller is configured to control one or more of said plurality of individually addressable LED-based light sources to result in one of said plurality of lighting effects, wherein said resulting lighting effect is based at least in part on the determined parameter of said object.
