Abstract

PROBLEM TO BE SOLVED: To provide a light source that can extend lifetime of a discharge tube. SOLUTION: In this light source, a heat radiator is made to contact with a side-on type discharge tube 10 with a projection 1pr. Light from the discharge tube 10 exits through a light exit window 1ww located atop the projection 1pr. The radiator is kept in contact with a sidewall 1w at a peripheral region 1ws, located on the foot of the projection 1pr. The radiator consists of a spring member 101sp, in direct contact with the peripheral region 1ws and a radiator block 101bl that connects the spring member 101sp to a radiator box 101bx. Because the substances produced by sputter or the like of electrodes in the discharge tube 10 deposit mainly on the peripheral region 1ws, quantity of materials deposited on the light exit window 1ww can be lowered to make lifetime of the discharge tube longer.

2. Description of the Related Art Lamps utilizing microwaves are disclosed in
No. 182910. The lamp described in this publication encloses a gas in a container and irradiates the gas with microwaves to excite the gas to generate light. The gas contains a fluorine-based gas, and the fluorine-based gas etches the inner surface of the quartz glass container, and Si impurities generated by the etching adhere to the inner surface of the container. Therefore, in the lamp described in the publication, a cooling pipe is penetrated into the container to adsorb impurities generated by etching with fluorine gas.

On the other hand, a discharge tube utilizing an arc discharge between electrodes has been conventionally known. Such discharge tubes are known. As a side-on type discharge tube, a deuterium lamp, a xenon flash lamp, and the like are known. A side-on type discharge tube encloses a gas such as deuterium or xenon in a container having a cylindrical side wall, and emits light emitted from the gas between the electrodes by a discharge between a pair of electrodes disposed inside the container. The light is output to the outside through the light exit window on the side wall.

[0005] However, even in a discharge tube such as a deuterium lamp or a xenon flash lamp, the output light intensity is reduced by prolonged use. This was initially thought to be due to the deterioration of the cathode. Of course, the cathode deteriorates with prolonged use, but the present inventors have found that the major cause of the decrease in light output is not the deterioration of the cathode. In other words, it has been found that the decrease in light output is due to the fact that the substance released into the container due to the sputtering of the cathode and the like accompanying the discharge between the electrodes in the discharge tube adheres to the light exit window of the container. Obtained. The present invention is based on such knowledge, and has an object to provide a light source capable of extending the life of a discharge tube.
