Abstract
An example lighting device includes a luminaire having a miniature illumination light source matrix including miniature illumination light sources configured to be driven by electrical power to emit incoming light rays for illumination lighting. Luminaire further includes an optical lens sheet positioned directly over and abutting the miniature illumination light source matrix and configured to extend over the illumination light source matrix and including an input surface coupled to receive the incoming light rays and an output surface lens array. Input surface is a substantially planar lateral surface extending across an entirety of the miniature illumination light source matrix. Output surface lens array includes a plurality of miniature optical lenses, including a respective miniature optical lens for each of the miniature illumination light sources to refract the incoming light rays into an outputted beam pattern of output light rays for the illumination lighting.
