Patent

CA 2205707

A closed-loop, tubular lamp envelope and methods of manufacturing closed-loop, tubular lamp envelopes are disclosed. A dome is formed at one end of a light-transmissive tube. A blister is molded on the dome, and a hole is formed in the molded blister. Next, a dome is formed at the other end of the light-transmissive tube. A blister is formed on the dome, and a second hole is formed in the molded blister. Each of the molded blisters includes a rim which defines the respective hole. A second tube is processed in the same way. The respective rims at the ends of the first and second tubes are fused together to form a sealed, closed-loop lamp envelope. Each tube may be bent to provide a desired shape of the lamp envelope. The molding of the rims insures that the sealing surfaces match.
