Abstract
This portable light source apparatus accommodates a deuterium lamp in a lamp box and housing in order to minimize influence of temperature changes in the outside air. The deuterium lamp, which is susceptible to changes in temperature, is enveloped both by the lamp box and the housing for accommodation in a double shield structure. Consequently, the temperature change of the housing, which is the most likely to be affected by the outside air, is harder to be transmitted to the deuterium lamp, whereby the latter can be utilized without consideration of weather changes during outdoor operations or influences of air conditioners and the like during indoor operations. The deuterium lamp can be inserted into and removed from the lamp box from thereabove, so that lamp replacement becomes easier even when the housing is made compact, whereby the light source apparatus can be carried easier outdoors and in the field.
