It is used to prevent
However, if the mesh of the net is made larger in order to increase the amount of light emitted, there is a problem that microwave leakage occurs, and there is a drawback that the use of the net must be done at the expense of light utilization efficiency. Ta.

3 is a magnetron antenna, 3 is a waveguide for guiding microwaves, 4 is a microwave cavity formed by rotationally symmetrical inner wall 41 and whose front opening is covered with a net 42, and 5 is an empty space. A microwave power supply port is provided at the joint between the body 4 and the waveguide 3, 6 is a spherical discharge lamp disposed within the cavity 4, and 7 is connected to the magnetron 1 and means (not shown). a fan 8 for cooling the discharge lamp 6 fixed to the
9 is a vent provided in a part of the waveguide 3, and 9 is a box that covers the magnetron 1, the waveguide 3, the cavity 4, etc.

12および取付ネジ13により固定されている。 In such a device, the above-mentioned net body 42
A second mesh body 43 is provided at a distance from the center. That is, the second net 43 is connected to the net 42 through a ring-shaped spacer 11 that corresponds to the flange 44 formed at the opening edge of the inner wall 41, and whose surfaces are parallel to each other. 42 and is fixed by the fixture 12 and the mounting screw 13 while being spaced apart from each other so as to form a space therebetween.

量を高めることができる。 In the microwave discharge light source device configured in this manner, the second net 43 allows the light that has passed through the net 42 to pass to the outside according to its own aperture ratio. On the other hand, unlike light, microwaves have the characteristic that the energy that passes through a mesh-like network is greatly attenuated. Therefore, the net body 42
Even if microwaves leak from the second net 43
effectively reflects microwaves. Therefore, net body 4
By appropriately selecting the aperture ratio of the mesh of the second net 42 and the second net 43 and the installation interval between the two nets 42 and 43, the amount of light emitted to the outside can be increased while preventing microwave leakage.

ある。 Note that both net bodies 42 and 43 in the above embodiment
The material used was formed by etching a metal plate having a thickness of several tens to hundreds of microns. Furthermore, if the aperture ratios of both the nets 42 and 43 are made the same, the number of types of parts can be reduced and errors during assembly can be prevented. Furthermore, by setting the aperture ratio of the net 42 to be smaller than that of the second net 43, microwaves can be effectively absorbed into the discharge lamp 6, thereby increasing the light output of the discharge lamp 6. be.
