The lamp envelope is rotated about an axis passing therethrough while at least a stream of cooling gas is directed at it. A plurality of such streams may be positioned in or near a plane in which envelope hot spots are found to develop. A spherical lamp envelope at the center of a spherical microwave chamber is effectively cooled by this technique. | |
