Light-emitting diode chip
Abstract:
A light-emitting diode chip comprising:—a semiconductor body (1) having a plurality of active regions (2), wherein—at least one of the active regions (2) has at least two subregions (21 . . . 28),—the active region (2) has at least one barrier region (3) arranged between two adjacent subregions (21 . . . 28) of said at least two subregions (21 . . . 28),—the at least two subregions (21 . . . 28) emit light of mutually different colour during operation of the light-emitting diode chip,—in at least one of the subregions (21 . . . 28) the emission of light is generated electrically, and—the barrier region (3) is configured to hinder a thermally activated redistribution of charge carriers between the two adjacent subregions (21 . . . 28), is specified.
