Abstract

A character generator for a printer or copier which illuminates a surface of a photoconductor is provided with a cooling device, wherein a line of LEDs is mounted on a bearing surface of a hollow, thin walled profile that runs along the direction of the LED row. The hollow interior is filled with a liquid. On the other side of the hollow profile from the row of LEDs is a heat dissipating structure, such as a finned heat sink.
