Abstract
A light fixture has an array of light emitting diodes arranged on a substrate, an array of lenses arranged adjacent the diodes, each lens corresponding to a diode, and having a center, the array of lenses arranged such that the each lens center is offset from a location of the diode. A light fixture has an array of light emitting diodes arranged in a x-y grid on a substrate, and an array of lenses arranged adjacent the array of light emitting diodes, each lens corresponding to a diode and having a center, the array of lenses arranged such that each lens center is offset a distance along a location axis of the diode.
