Abstract
A Christmas lamp with a base has a cylindrical portion formed with a plurality of lengthwise ribs and a plurality of lengthwise slots defined by the ribs.

And, inner contact surfaces of the ribs are in close contact with an outer surface of the lamp to keep the lamp secured in the base.
Claims1
An electrical lamp base system comprising:
- (a) an elongated electrical bulb having an exterior surface and a pair of electrical leads extending from a lower section of said electrical bulb;
- and,
- (b) a cylindrically contoured longitudinally extended base member for insert into a socket, said base member defining an open internal chamber for insert of said electrical bulb therein and a pair of hollow leg members extending from a lower section of said base member forming a pair of lead wire through passages in open communication with said base member open internal chamber, said base member having a sidewall formed by said open internal chamber, said sidewall having a plurality of longitudinally extending slots passing through said sidewalls, said electrical bulb inserted into said base member internal chamber for contiguous contact with an internal surface of said sidewall for providing structural support for said electrical bulb within said base member and allowing heat dissipation through said slots, said pair of lead wires extending through respective hollow leg members and deformed into electrical contact with said socket.
