CONTROL OF LUMINOUS INTENSITY DISTRIBUTION FROM AN ARRAY OF POINT LIGHT SOURCES

摘要

A luminaire that provides predetermined luminous intensity distribution, the luminaire comprising an array 100 of light-emitting elements 110 and, disposed over the light-emitting elements, a lens array comprising a plurality of aspheric lens elements 150 each optically coupled to a respective one of light-emitting elements 110 and producing an out-of-focus image thereof, the images combining to generate a predetermined luminous intensity distribution, e.g., providing constant illuminance on a plane.
