Abstract
An imaging light source module that includes a plurality of light guides, a plurality of light emitting sources, and an intermediate image surface is disclosed. Each of the plurality of light guides has an entrance face, an exit face, and at least one side wall, and all of the light guides are capable of delivering light along associated light distribution axes intersecting a common reference point. Each of the plurality of light emitting sources delivers light only to a single light guide of the plurality of light guides. The intermediate image surface comprises a plurality of pixels, where each pixel receives light from the exit face of a single associated light guide of the plurality of light guides.
