Abstract
Optics and optical devices and systems are disclosed that employ a plurality of refractive and/or reflective optical elements, such as lenses and mirrors, with different shapes to achieve a desired illumination pattern. In various aspects, a plurality of lenses in which at least two of the lenses have different boundary shapes are arranged, e.g., according to a predefined pattern, to receive light from one or more light sources and to redirect the received light to form collectively a desired far-field illumination pattern. For example, the lenses can be configured such that the far-field illumination pattern has a boundary shape that is different from the boundary shape of a far-field illumination pattern that can be provided individually by the lenses.
