Abstract
PURPOSE: To stably maintain high strength for a long time and to provide a light output having high resolution and a uniformity covering a wide area, by providing a means to support a microwave excitation type electrodeless light source in a microwave cavity in a freely rotatable state and a specific reflector. CONSTITUTION: In the upper part of a solid wall part 8a of a microwave cavity 8, a stem 18a with a spherical lamp 18b fixed to its free end is supported by two bearings 20, 23, a part to be rotated by a motor 25 through a sprocket 24 is composed of an end wall 11, a plate 22 and the like, and a microwave is introduced from a magnetron 15 through a wave guide 14 into a slot 10a provided on a side wall 10. Plural slots are provided to obtain a high output. In the lower part, a block 12 having a nozzle 31 to blow cooling gas for a lamp is provided. A mesh wall part 8b allows light to pass through but reflects the microwave. A multi-facet type reflector 40 uniformly irradiates light of high resolution on a wide area on a picture surface. An aperture part is protected by a screen 42 and a glass plate 44.
