Deuterium lamp box and portable light source apparatus

Abstract

In a deuterium lamp box in accordance with the present invention, a wavelength of light different from that of a deuterium lamp can be forwardly let out from a light exit opening. Namely, when the deuterium lamp of a see-through type is lit, the light generated from the deuterium lamp can be let out from the light exit opening. When a second lamp is lit while the deuterium lamp is turned off, the light generated from the second lamp 85 passes through the deuterium lamp while in a state collected by a lens, and is let out from the light exit opening. When the deuterium lamp and the second lamp are lit at the same time, different wavelengths of light are let out from the light exit opening while in a mixed state. Thus, three kinds of light can be made depending on how the lamps are lit, whereby this lamp box is considered to have a versatility much higher than that of a lamp box accommodating only one lamp.
