Disclosed is an LED lighting array comprising at least one multilayer circuit board (1), on which LED chips substantially emitting in one direction are arranged on several staggered metal layers (21, 22, 23, 24) in order to form planar emitters having a three-dimensional structure, at least one electrical connection of an LED chip (2) to the metal layer (n) on which the LED chip is mounted, at least one other direct electrical connection (4) of an LED chip (2) to the metal layer (n+1) lying thereabove, and at least one more electrical connection between the metal layer (n) and a lower-lying metal layer (n-1). |
