Abstract
This portable light source apparatus accommodates a deuterium lamp in a lamp box and, at the same time, in a housing in order for the influence of temperature changes in the outside air to become very small. Namely, the deuterium lamp, which is susceptible to changes in temperature, is enveloped not only by the lamp box but also by the housing, thereby being accommodated in a double shield structure. Further, it has been known that ozone is generated when ultraviolet rays are emitted in the air. Therefore, a light guide tube for extending a light exit opening of the lamp box is provided, so that cooling winds do not traverse the ultraviolet rays. As a result, ozone is restrained from occurring in the part where the ultraviolet rays occur within the housing, whereby the emitted light is appropriately kept from fluctuating due to the occurrence of ozone.
