出し効率を上げるものである。Conventionally, a technique for inserting a white light reflecting plate into the cavity of a microwave-operated lamp is described in Japanese Utility Model Application No. 104559/1983. This device consists of a microwave power source, a waveguide, and a microwave cavity. The cavity is hemispherical, and a spherical electrodeless lamp is placed inside it. The flat part of the cavity is made of wire mesh to extract light, and the inside of the spherical part is made of mirror-finished material such as aluminum to reflect light. A hole is provided in the spherical cavity to supply power from the waveguide. This hole does not reflect light, resulting in a loss. The above conventional technology is
A white ceramic reflector is placed in this hole to increase the efficiency of light extraction.

では加工が難しい。In the above-mentioned conventional technology, a part of the light reflecting surface is made of ceramic, and most of the other part is made of metal such as aluminum. When aluminum is used at high temperatures for long periods of time, it undergoes oxidation and other deterioration, resulting in poor light reflectance. To prevent this, the entire reflective surface could be made of a stable material such as ceramic, but it would be difficult to process a spherical cavity like the conventional technology.
本発明の目的は、加工が簡単で、かつ、安定な光反射板

Among them, for example, rare gases, rare gases and Hg, Cd, Zn.
, various metals such as As or their halides,
Contains iodine, diuterium, etc. When using ultraviolet light, the lamp 2 is made of an ultraviolet-transmissive material such as quartz. The lamp 2 is lit by high-frequency induction discharge, so there is no need to attach electrodes.Microwave power is supplied from the microwave power supply 6 through the waveguide 5 and the power supply port 4 to the empty IrF41
to go into. The microwave power source 6 has frequencies 2 and 4, for example.
It is a magnetron with a frequency of 5 GHz and a wavelength of 12.24 c+m. At least one side of cavity 1 extracts light,
It has wire mesh 3. Due to this configuration.
