<p>A portable light source comprises a lamp (10) contained in a lamp box (42), which is housed in a case (41) to significantly reduce the influences of ambient temperature. In other words, the deuterium lamp (10), likely to be influenced by temperature, is enclosed in a double shield structure including the case (41) as well as the lamp box (42). As a result, the deuterium lamp (10) is kept fairly insensitive to the change in temperature of the case (41) that is most affected by ambient temperature, so the light source can be used outdoors regardless of the weather and indoors regardless of the influence of the air conditioner. Since the lamp box (42) is adapted to receive the deuterium lamp (10) through its top, the lamp (10) can be easily replaced if the case (41) is designed compact, thus increasing the portability of the light source outdoors.</p> |
