BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a socket used for a rod-shaped incandescent lamp.

[0002]

2. Description of the Related Art In recent years, the development of a rod-shaped incandescent lamp has made great progress and is reaching a practical level. Even if the rod-shaped incandescent lamp is put to practical use, it can be said that the cap of the rod-shaped incandescent lamp has a different structure and shape from the caps of the conventional spherical incandescent lamp and rod-shaped fluorescent lamp. That is, unlike the structure and shape in which a plurality of cap pins are axially projected from the end face of a cylindrical base such as a spherical incandescent lamp or a cylindrical base such as a rod-shaped fluorescent lamp, a relatively thick wall It is assumed to have a prismatic plate-like structure. However, even if the rod-shaped incandescent lamp has such a relatively thick-walled prismatic plate-shaped base, there is currently no socket adapted to it. Therefore, development of a socket adapted to a rod-shaped incandescent lamp is desired.

[0003]

The problem to be solved is that there is no socket suitable for a rod-shaped incandescent lamp.
