Abstract
A phosphor layer is formed efficiently in a gas discharge tube by drawing a mother material to fabricate a supporting member which is insertable in a small glass tube used for a gas discharge tube, forming a phosphor layer on the supporting member, and inserting and placing the supporting member in the small glass tube.
Claims11
A method for forming a phosphor layer in a gas discharge tube having discharge gas introduced therein and defining a discharge space, comprising:
- drawing a mother material to fabricate a supporting member which is insertable in a gas discharge tube;
- forming a phosphor layer on a surface of the supporting member;
- and
- inserting into the gas discharge tube the resulting phosphor layer supporting member having the phosphor layer formed thereon.
A method for fabricating a phosphor layer supporting member for supporting a phosphor layer in a gas discharge tube, comprising:
- drawing a mother material having an almost arc-shaped cross section similar to an outer shape of a gas discharge tube to fabricate a supporting member, the supporting member having an almost arc-shaped cross section of a size that is insertable in the gas discharge tube so as to form a phosphor layer on an arc-shaped internal surface of the supporting member.
