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.

Abstract: A projector can include a projection lens that is positioned substantially one focal length away from a spatial light modulator. The projector may also include a non-imaging optic configured to illuminate the spatial light modulator. The non-imaging optic may include a light emitter and an etendue-preserving reflector. The projector can be configured to project an image created by the spatial light modulator at a distance using light from the non-imaging optic.

Abstract: This disclosure provides systems, methods, and apparatuses for array illumination. In one aspect, an array of light engines is coupled to a support structure. Each light engine can be separately controlled to achieve a desired output beam. In another aspect, a support structure includes an array of LED emitters. The support structure is configured to removably receive a plurality of light guides over the array of LED emitters, thereby forming an array of light engines. The support structure can include an integrated heat sink in thermal communication with the array of LED emitters. Light from the LED emitters is distributed over the surface of the light guides to produce a desired output beam. The light engines can be configured to produce output beams of differing color, direction, shape and/or size.

Abstract: This disclosure provides systems, methods, and apparatuses for a multi-beam light engine. In one aspect, a light source is coupled with an optical film such that light emitted from the light source passes through the optical film. The optical film can be a composite film including one or more sections, each of which is configured to operate differently on the input beam emitted from the light source. The optical film can be configured to produce one or more output beams of differing color, direction, and/or beam width.

Abstract: An illumination apparatus includes a light bar, a plurality of indentations in the light bar on a first side of the light bar, and a contoured reflective surface including a plurality of protruding surface portions, such that the surface portions reflect light transmitted through sloping sidewalls of the indentations. The light bar has a first end for receiving light from a light source. The light bar includes material that supports propagation of the light along the length of the light bar. The turning microstructure is configured to turn at least a substantial portion of the light incident on the first side and to direct the portion of light out the second opposite side of the light bar. The protrusions on the contoured reflective surface and the indentations on the light bar can have complimentary shapes and/or aligned in certain embodiments.

Abstract: In various embodiments described herein, a front light guide panel comprises a plurality surface relief features having a variety of different sloping surface portions. Light injected into an edge of the light guide propagates though the light guide until it strikes one of the surface relief features. The light is then turned by total internal reflection such that the light is directed onto a reflective modulator array rearward of the light guide panel. The light reflects from the modulator array and is transmitted back through the surface features of the light guide panel. However, depending upon where the light is incident on the surface features, the light will be refracted at different angles by the different sloping surface portions. As a result, light reflected from a single point on the modulator array appears to originate from different locations, and ghost images appear.
