摘要：
A cooling device for cooling a light-emitting semiconductor device, such as a LED device (20), comprises a ceramic plate (15) having coolant-conveying channels (12) incorporated therein. The ceramic plate (15) is adapted for forming an integral part of the optical system of the light-emitting semiconductor device (20) and to cool a light-emitting portion (26) of the light-emitting semiconductor device (20). 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.
