    Abstract: A compact lamp unit and associated socket for use in a projection system such as a slide projector, microfilm viewer, and so forth. The lamp unit includes a reflector molded from a plastic material and an electric lamp secured within the reflector. In order to decrease the axial dimension of the reflector and to avoid the use of pin connectors, electrical contacts for the lamp are pressed into recesses formed in the outer surface of the reflector. The reflector includes an opening at its apex through which electrical leads from the lamp extend outwardly of the reflector. The electrical leads are secured to the contacts by being forced into the recesses along with the contacts. This construction technique is fast and simple.The lamp unit also includes a handle to enable a heated lamp unit to be replaced by the user and a guide means to enable the lamp unit to be oriented quickly and accurately upon insertion into the socket.

    Abstract: The efficacy, life and beam intensity of a sealed-beam headlamp are enhanced by employing a compact baseless halogen-cycle incandescent lamp as the inner light source and mounting it in optically coupled relationship with the reflector component of the sealed-beam housing by a holder assembly that is rugged, light in weight, and inexpensive from both a material and manufacturing standpoint. The holder assembly comprises one or several sheet-metal components that are locked in embracing interfitting relationship with the press seal of the lamp envelope by welding the components to one or more of the lamp lead-in conductors and to the rigid main conductors carried by the reflector component. The halogen-cycle lamp and its rigid lead-in conductors thus constitute integral structural parts of the finished mount that mechanically retain the various components in their assembled relationship.

    Abstract: An improved lamp and socket assembly is disclosed in which a socket collar is mechanically secured to the 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.

  • Patent number: 4056718
    Abstract: A wide beam floodlight fixture by which the light from a lamp bulb that radiates light in all directions away from its axis, directs that light in a wide well defined beam. The fixture comprises a housing with a transparent front wall, and opposite opaque top, bottom and side walls. A curved reflector in the rear of the fixture housing embraces the lamp bulb and directs its light out of the transparent front wall. The top and bottom walls of the fixture have aligned access ports through either of which the lamp bulb may be removed and replaced. A socket housing removably attached to the bottom wall of the fixture housing closes the bottom access port and has the socket for the lamp bulb base shock-resistantly mounted therein. The access port in the top wall of the fixture housing is closed by a removable cover, from the underside of which a flanged ring is resiliently supported to embrace the upper end portion of the lamp bulb.
