ABSTRACT:
A foamable copolymer based coupling is provided for securely affixing a light emitting glass lamp in a metal base to form a lamp assembly. The copolymer is preferably selected from ethylene vinyl acetate, ethylene methyl acrylate, and combinations thereof. The foamable coupling may be placed around one end of the glass lamp or in the lamp base before the lamp and base are matingly engaged. The assembled lamp is then heated to a temperature, which causes the foamable coupling to expand and securely affix the lamp in the base.
