Abstract
There is disclosed an electric lamp assembly with a threaded base, the assembly including a lamp envelope, a threaded base, and a light source. The electric lamp with threaded base includes portions of the threaded base positioned in concavities formed on a tubular end of the lamp envelope. No melt junction, and no glues are needed in coupling the envelope and base. The coupling is strong enough to resist decoupling by hand and grows stronger with time.
