Lamp ribbon
First Claim
1. A lamp ribbon, comprising:
- (a) a thin flexible belt construction, comprising;
(a1) an upper belt layer and a lower belt layer, each generally formed as a strip and made of a flexible electrically insulating material, said upper and lower belt layers being laid against one another, aligned together, and fixed to one another continuously along their respective lengths; and
(a2) two conductors, each formed as a strip and made of an electrically conducting material, which are laid between said upper belt layer and said lower belt layer parallel to one another and separated by a certain distance, and which are held by being sandwiched between said upper belt layer and said lower belt layer;
(a3) parts of said lower belt layer at a plurality of places thereon being absent, so as to expose said two conductors for a certain longitudinal distance at each of said plurality of places, at each such place a pair of apertures being formed through said upper belt layer between said two conductors so as to open to said place; and
(b) a plurality of lamp units, each comprising;
(b1) a bulb socket which is rigidly attached to said belt construction opposed to a one of said plurality of places where said lower belt layer is absent;
(b2) a pair of terminals which protrude from said bulb socket, each of said terminals passing through one of the pair of apertures formed in said upper belt layer opening to said one of said plurality of places and then being bent over and being soldered to one of said conductors; and
(b3) a bulb comprising a pair of terminals and a bulb base into which said bulb is detachably fitted with said terminals of said bulb being bent so as to hold said bulb to said bulb base, said bulb base being slidably fittable into said bulb socket so that each one of said pair of terminals of said bulb is thus electrically connected to one of said terminals of said bulb socket.

Abstract
A lamp ribbon is made of a number of lamp units fixed to a belt construction. The belt construction is made of an upper belt layer and a lower belt layer, each generally formed as a strip and made of a flexible electrically insulating material, which are laid against and fixed to one another, and also includes two strip shaped conductors which are laid between the upper and lower belt layers in parallel and are sandwiched therebetween. Parts of the lower belt layer at a number of places are absent, so as to expose the two conductors for a certain distance at each of these places, and at each such place a pair of apertures are formed through the upper belt layer between the two conductors. Each of the lamp units includes a bulb socket abutted against a part of the outer surface of the upper belt layer opposed to one of the places where the lower belt layer is absent. The bulb socket has a pair of terminals which protrude from it, and each of these terminals passes through one of the corresponding pair of apertures in the upper belt layer and then is bent over and soldered to one of the conductors. A bulb is detachably mounted to the bulb socket, and has a pair of terminals each of which is electrically connected to one of the terminals of the bulb socket.
