Abstract: The present disclosure describes a plasma illumination device with microwave pumping, comprising: a hermetically sealed casing, a magnetron, a microwave resonator containing a rotatable electrodeless plasma lamp, a coaxial coupling line running parallel to the casing axis, for transmitting microwave power from the magnetron to the microwave resonator, at least one heat sink located on the inner walls of the casing and providing heat transfer through the casing to the external environment, and a light-transmitting hermetically sealed hollow cylinder fitted in a hermetically sealed way on the casing above the microwave resonator. This results in an illumination device with microwave pumping, which may be used to illuminate objects located in unfavorable environmental conditions, particularly those in which there is a high content of dust or other contaminants, or in an aqueous environment at great depths.
