Abstract:
The invention relates to an electroluminescent lighting device, which is based on an array of standard electroluminescent tiles (D1-Dn) combined with an array of ballast components (R1-Rn) mounted on a carrier board (30) in such a way that the power loss is evenly spread across the whole board area to minimize local electric power in the ballast components. The unavoidable remaining hot spots and electroluminescent tiles are thermally coupled in such a way that the additional thermal load on the electro-luminescent emission layer is as symmetric as possible with respect to the self heating of the electroluminescent device. This can be achieved by a combination of properly designed heat spreading and thermal isolation of the electroluminescent and ballast components. Heat spreading is achieved by a properly designed interconnection structure (40) on the carrier board. Different options are proposed to thermally isolate the electroluminescent tiles from the hot spots.
