Abstract: A battery housing electrical connector assembly that utilizes a pair of plates with these plates to be lockingly connected together in an interlocked position. The locking together is achieved through the use of a pair of plug type electrical connectors each of which matingly connects with an opening. A connecting arrangement between the two plates is achieved by one plate being moved in a lineal direction with the other plate. There being at least one auxiliary electrical connector in the form of a protruding pin connected between the first plate and the second plate. The plate that does not have the protruding pin has an electrical contact which is to be moved transversely to the lineal direction to be either in contact with the protruding pin to achieve an electrical connection or to be spaced from the protruding pin not achieving an electrical connection. The battery housing is to also include an illuminatable display panel upon which is to be imprinted informative indicia.

Abstract: A portable high energy light having a U-shaped housing and vented cover. The housing has a front section containing light treatment parts and a back section containing a bulb assembly. The front section is cooled by an elongated slot directing ambient air between the light treatment parts and bulb assembly. The back section is cooled by an enlarged opening in the housing bottom wall located directly below the bulb assembly. A guard flange extending into the opening helps guide ambient air directly past heat generating portions of the bulb assembly.

Abstract: An electric light having a housing enclosed on the top and back end by a pivotable cover. The cover is hinged at the back upper corner of the housing sidewalls. A bulb and socket assembly is secured to a flange extending from the cover interior. The flange conducts heat from the bulb and socket assembly to the cover for dissipation into the atmosphere. When the cover is lifted by rotation about the hinge connection, the assembly will rotate with the cover and be readily accessible for repair or bulb replacement. For additional cooling, the cover back end is spaced from the housing to permit a flow of cooling air past the bulb and socket assembly.

Abstract: A portable electric lighting device is provided having an open top closable by two rotatable members oppositely hinged. The members allow easy access to the interior of the device for bulb, light filter or lens changing. Heat from the lamp is dissipated by including air vents in the members and constructing at least one member with heavy heat conductive material. The device includes a bulb ejector lever and resilient biasing wires to maintain the bulb in a secure position.
