Patent ID: 8157418

Claim:
An illumination device ( 1 ) comprising at least one substrate plate ( 2 ), at least two light-emitting diodes ( 3 ) (LEDs) arranged on the same side (A) of the substrate plate ( 2 ), the LEDs ( 3 ) are each embedded into a housing ( 6 ) placed on the substrate plate in order to dissipate waste heat of the LEDs ( 3 ), and at least one electrically conductive cooling device ( 8 ) arranged on the opposite side (B) of the substrate plate ( 2 ) wherein at least two LEDs ( 3 ) are thermally operatively connected to the cooling device ( 8 ) by means of in each case at least one thermal coupling device ( 9 ) formed from an electrically conductive material, characterized in that the cooling device ( 8 ) has at least two regions ( 8 a , 8 b , 8 c ) which are electrically isolated from one another, wherein a first region ( 8 b ) is thermally and electrically operatively connected to at least one first LED ( 3 ), and a second region ( 8 a , 8 c ) is thermally and electrically operatively connected to at least one second LED ( 3 ) and characterized in that at least one mechanical connecting element ( 13 ) is arranged between at least two regions ( 8 a , 8 b , 8 c ) of the cooling device ( 8 ) while maintaining the at least two regions electrically isolated from one another.
