Abstract
A cooling device for cooling a light-emitting semiconductor device, such as a LED device (), comprises a ceramic plate () having coolant-conveying channels () incorporated therein. The ceramic plate () is adapted for forming an integral part of the optical system of the light-emitting semiconductor device () and to cool a light-emitting portion () of the light-emitting semiconductor device (). A method of forming a cooling device comprises the steps of forming a charge of ceramic particles, embossing the charge with a stamp to form coolant-conveying channels in the charge, hardening the charge, and providing a cover on top of the channels to seal them.
