Abstract

PURPOSE:To obviate softening of adhesives binding a stem and an inner tube, by securing a couple of inner tubes with a sealed electrode each, in an airtight state, to the inner tube insertion hole formed in a stem, after the stem has been sealed on the bottom of an outer tube. CONSTITUTION:After a stem 3 provided with a couple of inner tube insertion holes has been sealed on the bottom of a cylindrical glass-make outer tube 1 in which mercury and a noble gas are sealed up, an electrode 6 is air-tightly sealed to one end in the inner tube insertion holes, while phosphor layer clad somethings 8 are inserted through into the inside wall of the paired rectilinear glass inner tubes 5 having the other end opened and bonded to the stem 3 with glass frit 7 whereby a compacted discharge lamp is thus made up. Therefore, the glass frit 7 can securely hold the inner tubes 5 without causing any heat liable to possible softening after it has been set. Thus, any tilt of inner tubes 5 or generation of gap(s) may be prevented, duly enhancing the grade of product as merchandise.

A typical example is a disk-shaped stem (3) K with an electrode (6) protruding from it, and an inner tube (5) with both ends open so as to contain the electrode (6) therein. The stem (3) is further sealed to the outer tube (1) to form a discharge path regulated in a U-shape by the inner tube (5) within the outer tube (1). (9) Thin tube for public exhaust. Therefore,
The size of the tube can be reduced to about 1/2 that of a straight tube discharge lamp, and the light source can be made similar in shape to a conventional incandescent light bulb.
