The present invention discloses a dual spiral fluorescent lamp that is
smaller in volume than a conventional one. To provide for a reduced size
compact fluorescent lamp, the end portions of the spiral glass tube are
anchored into the holes within the cover of a bi-pin case. Inside of each
end portion is a glass stem through which a pair of cathode support wires
are passed. The cathode itself is welded to the extreme ends of each
cathode support wire. To achieve the short-legged lamp, the cathode
support wires lying between the cathode and the stem are bent downward at
approximately 60 degrees from the vertically positioned stem. Therefore,
by successfully avoiding the cathode coming in contact with the phosphor
coating lining the interior of the tube, which may affect the natural
lighting emitted by the fluorescent lamp, the two end portions of the
fluorescent lamp of the present invention can be much shortened,
resulting in a smaller volume than a conventional compact fluorescent
lamp.
