Reduction of defective pixel appearance in light-emitting arrays

A lighting system comprising:

• a light-emitting module comprising
• an array of LEDs, one or more of the LEDs being defective,
• a set of one or more transmissive optical elements positioned at a light-emitting surface of the LED array, each transmissive optical element of the set being positioned at a location of a corresponding one of the one or more defective LEDs and extending over the corresponding defective LED and laterally at least partly over one or more LEDs of the array adjacent to the corresponding defective LED, and
• a power and control module including circuitry structured and connected so as to enable selective activation of one or more LEDs of the array or one or more groups of LEDs of the array,
• each transmissive optical element of the set being arranged so as to transmit laterally at least a portion of light emitted by the one or more corresponding adjacent LEDs to propagate away from the array from the location of the corresponding defective LED;
• and
• a set of one or more secondary optical elements arranged for projecting an image of the array of LEDs, lateral transmission of light by each transmissive element resulting in reduced or eliminated appearance of the corresponding defective LED in the image of the array.
