Abstract (en)
A recording head comprises a linear array of light-emitting diodes (LEDs) on a common thermally conductive LED carrier bar (30). The carrier bar carries a series of modules, each module containing N LEDs with their associated drivers. The carrier bar is provided with a cooling means in thermally conductive contact therewith. The cooling means comprises a U-shaped duct inside a thermally conductive body (50) in thermally conductive contact with the carrier bar (30), said duct extending between a fluid inlet and a fluid outlet. The duct (57) has flowing therethrough a cooling fluid such as water. <IMAGE>
