Abstract From the Canadian patent

An improved lamp and socket assembly is disclosed in which a socket collar is mechanically secured to a panel or reflector when the lamp is used. The base of the lamp attaches to the collar as does the electrical connector. The combination enables a more repeatable alignment of the lamp in the panel or reflector. A compact assembly is achieved by using nested cylinders in the parts.
