FIELD: physics.
SUBSTANCE: disclosed method involves placing bunches with a defined number of series-connected light-emitting elements (LEE) in an integral field in closed rectangular or square LEE fields lying in series from the centre. If that number is not a multiple, then its remainder or arrear is carried from neighbouring rectangular fields with an excess number of LEE by slightly transforming the boundary of neighbouring fields. The formed bunches of LEE are placed in fields in groups or in alternating sequences or all bunches are connected in parallel. The area of LEE and the size of the substrate are determined based on the given radiation power, the number of elements in the bunch and the number of bunches with constant current density in the LEE.
EFFECT: high density of arranging bunches of light-emitting elements in their integral array, invariable form of radiation of the light-emitting device when one or more bunches break down, reliability of the light-emitting array in manufacturing processes, inspection, classification, operation and, as a result, high yield of effective items.
