Claim Text:
1. An electroluminescent device comprising: a) a plurality of standard electroluminescent segments; b) a plurality of standard load elements; c) a common carrier substrate on which said electroluminescent segments and said elements are mounted; d) an interconnecting structure that is distinct from said load elements for connecting said electroluminescent segments and said load elements and for providing a predetermined heat spreading; and e) an isolation structure for thermally isolating said electroluminescent segments from hot spots created by said load elements; f) wherein said interconnecting structure and said isolation structure are arranged to combine said predetermined heat spreading and thermal isolation in such a way that local power loss is minimized at hot spots on said common carrier structure and that additional thermal load on an emission layer of said electroluminescent segments is symmetrized with respect to self heating of said light emitting device.
