Abstract
A light module for a vehicle lighting device comprises a semiconductor light source mounted on a carrier element designed. on/including a first printed-circuit board. A control module is electrically connected to and structurally spaced from the light source and designed on/includes a second printed-circuit board and includes an electric circuit constructed upon the second board and a connection element adapted w be connected to a higher-level controller and/or vehicle power supply. The control module is an electronic component of the light source such that a cable does not connect the control module and light source to each other. A highly thermally conductive carrier module is arranged between the light source and control module and directly attached to the carrier element, second printed-circuit board, and electric circuit. An electrical connection is located on the carrier module between the fight source or carrier element and electric circuit or second printed-circuit board.
