Title:
重水素ランプボックス及びポータブル型光源装置
Document Type and Number:
Japanese Patent JP4326631
Kind Code:
B2
Abstract:
In a deuterium lamp box 50 in accordance with the present invention, a wavelength of light different from that of a deuterium lamp 10 can be forwardly let out from a light exit opening 69. Namely, when the deuterium lamp 10 of a see-through type is lit, the light generated from the deuterium lamp 10 can be let out from the light exit opening 69. When a second lamp 85 is lit while the deuterium lamp 10 is turned off, the light generated from the second lamp 85 passes through the deuterium lamp 10 while in a state collected by a lens 84, and is let out from the light exit opening 69. When the deuterium lamp 10 and the second lamp 85 are lit at the same time, different wavelengths of light are let out from the light exit opening 69 while in a mixed state. Thus, three kinds of light can be made depending on how the lamps 10, 85 are lit, whereby this lamp box is considered to have a versatility much higher than that of a lamp box accommodating only one lamp.
