Abstract
A lighting module has an array of light emitting elements arranged on a substrate in an x-y grid, and a reflector plate arranged on the substrate, the reflector plate having an array of openings arranged on an x-y grid such that the openings correspond to the light emitting elements, the dimensions of the reflector plate and the openings arranged to partially collimate light from the light emitting elements. A method of manufacturing a lighting module includes arranging an array of light emitting elements on a substrate, manufacturing a reflector plate having an array of openings, the openings located so as to correspond to the light emitting elements and created so as to only partially collimate light from the light emitting elements, and attaching the reflector plate to the substrate such that each opening in the reflector plate is centered on a light emitting element.
