Abstract:
1. A lighting device, comprising: at least a first light control element comprising light control structures; at least a first light source positioned so that at least a portion of light emitted by the first light source passes through at least a portion of the first light control element; at least a first luminescent material, at least a portion of the first luminescent material spaced from the first light source, the first luminescent material positioned so that at least a portion of light emitted by the first light source excites at least a portion of the first luminescent material, wherein each light control structure causes light that is incident on the light control structure to be at least one of (1) collimated, in which at least 50% of incident light is caused to travel in a first direction or substantially parallel to the first direction, and (2) distributed, in which comparatively less light incident on the light control structure is directed to a location directly below the light control structure and comparatively more light is directed to one or more locations spaced from directly below the light control structure.
