Abstract:
An array of light-emitting elements, having a light-emitting surface side and a semiconductor layer of a first conductive type, with a plurality of light-emitting regions of a second conductive type disposed in the semiconductor layer, the light-emitting regions emitting light through the light-emitting surface side, the semiconductor layer having an edge positioned so as to reduce a useful intensity of light emitted by a first one of said light-emitting regions that, among said light-emitting regions, is closest to said edge, comprising:at least one emission-altering element extending from the light-emitting surface side into the semiconductor layer, separated from all of the light-emitting regions, separated from a second one of the light-emitting regions by a distance substantially equal to a distance from said edge of the semiconductor layer to said first one of the light-emitting regions altering an amount of light emitted from said second one of the light-emitting regions with no other intervening emission altering elements.
