Beam pattern projector with modulating array of light sources

Abstract

This disclosure provides systems, methods and apparatus for a beam pattern projection device that includes a modulating array of light sources. In one aspect, the beam pattern projection device may include a lens. The array of light sources can be positioned such that its output plane is substantially one focal length away from the lens along the optical axis. The output of the array of light sources can be controllable to create an adjustable beam pattern out of a plurality of possible beam patterns that are each associated with a power level of each light source in the array of light sources. The device can project at a distance the adjustable beam pattern created by the array of light sources.

Description

technical field [0001] The present invention relates to light projectors comprising, for example, compact light engines for use in directional lighting applications. Background technique [0002] Directional lighting systems are often used in illuminating displays. The system also finds use in architecture, theater and other applications. For example, directional lighting systems can be used in stores to illuminate product displays, or in museums and art galleries to create frames for objects of interest. The system can also be used to provide accent lighting in buildings or aerial spotlights in theater productions. Typically, if the target, beam pattern, spot size, brightness, or some other property of such a directional lighting system is to be reconfigured, a human operator must physically access the lighting system to make such adjustments. This can be inconvenient in situations where, for example, the directional lighting system is located out of human reach or other...
