Abstract
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.
