DEUTERIUM LAMP
First Claim
1. A deuterium lamp comprising:
- a light-emitting portion having a cathode and an anode for generating an electric discharge, and emitting a discharge light toward a predetermined direction;
a sealed container having a storing space in which said light-emitting portion is stored while being filled with a deuterium gas, said sealed container having a hollow body portion for which said light-emitting portion is stored in an internal space constituting a part of the storing space, and a hollow guide portion extending along an emitting direction of a discharge light from said hollow body portion with its internal space being directly communicated with the internal space of said hollow body portion and on whose front end a light exit window for emitting the discharge light out side is provided;
an axis adjusting member extending along a predetermined center axis and at whose both ends openings are provided, said axis adjusting member being fixed to said hollow guide portion while storing at least a part of said hollow guide portion; and
a sealing layer including an adhesive material, provided between an outer periphery surface of said hollow guide portion and an inner wall surface of said axis adjusting member, said sealing layer fixing said axis adjusting member to said hollow guide portion with the center axis of said axis adjusting member being made coincident with the emitting direction of a discharge light.

Abstract
The present invention relates to a deuterium lamp with a structure to enable high-accuracy positioning with respect to a mounting object such as an analyzer. The deuterium lamp comprises a sealed container in which a light-emitting portion to emit a discharge light in a predetermined direction is stored. The sealed container is constituted by a hollow body portion in which the light-emitting portion is stored and a hollow guide portion which guides a discharge light from the light-emitting portion to a light exit window provided at its front end. The deuterium lamp further comprises an axis adjusting member fixed to the hollow guide portion while storing at least a part of the hollow guide portion and a sealing layer for fixing the hollow guide portion and the axis adjusting member to each other. In particular, the sealing layer makes it possible to fix the axis adjusting member to the hollow guide portion with the center axis of the axis adjusting member being made coincident with the emitting direction of a discharge light. Thereby, even when misalignment has occurred between the center axis of the hollow guide portion and the emitting direction of a discharge light due to a manufacturing error in manufacturing of the container, since the axis adjusting member itself is directly fixed to the mounting object, it becomes possible to fix said deuterium lamp to an analyzer or the like with the optical axis aligned at a high accuracy.
