Abstract
A stoplight system that includes a light source for providing a light output, and an array of non-overlapping lenslets comprised of first lenslets and second lenslets, each first lenslet configured to refract a portion of the light output of the light source into a first predetermined angular field comprising a central angular region having vertical and horizontal extent, and each second lenslet configured to refract a portion of the light output of the light source into a second predetermined angular field comprising first and second peripheral angular regions that are horizontally on either side of the central angular region, whereby the portions of the light output of the light source that are refracted by the first and second lenslets form stoplight illumination.
