Abstract
An LED arrangement (light emitting diode) has a plurality of adjacent radiating LEDs that are nearly identically aligned for forming an extended area light source. The LEDs are attached to a metallic multi-film support having sandwich-like insulating intermediate layers and having at least a step-like structure with at least one step. At least one LED chip is placed on each step on a metal film and the metal layer directly above is formed of a corresponding shortening or recess for mounting an LED.
