Abstract:
An electric, incandescent lamp including an electrically insulating (e.g., plastic) base which is securedly positioned on the lamp's sealed end portion without the need for adhesives or the like. The base functions to securedly retain the lamp's lead-in wires (a total of four in a dual filament lamp) in a preestablished alignment externally of the lamp's sealed end (from which the wires project) to thereby assure positive electrical connection thereto when the lamp and base are inserted within a corresponding electrical socket. The invention is ideally suited for use in a tail light assembly for an automobile.
Abstract:
A lamp base having an vibration adjustable support structure is disclosed. By supporting a bulb on a plastic clip having arms with fixed lengths, the rotational and axial location of the lamp may be fixed within a standard optical structure, such as reflector housing and lens system. The arms may then be oriented either radially, angularly, or as to thickness or width to control vibration transmission particular to a typical use. For example, standard bulbs, bases and reflector housings may be used with bulb holders variably tuned to accommodate the vibrations specific to particular vehicle models.
Abstract:
An improved electric lamp including an electrically insulating (e.g., plastic) base which is securedly positioned on the lamp's sealed end portion without the need for adhesives or the like. The base functions to securedly retain the lamp's lead-in wires (a total of four in a dual filament lamp) in a preestablished alignment externally of the lamp's sealed end (from which the wires project) to thereby assure positive electrical connection thereto when the lamp and base are inserted within a corresponding electrical socket. This wire retention is possible by embedding each conductor within designated channels in the base and subsequent deformation of the base's material to substantially cover the embedded wire. In addition, a locking arrangement between the lamp envelope's press sealed end and the base is provided to assist in retaining the sealed end within an opening within the base. The invention is ideally suited for use in a tail light assembly for an automobile.
Abstract:
A lamp base having a clipped together support structure is disclosed. Assembly and orientation of lamps is facilitated by a bulb that first clip couples to a bulb and the bulb holder is in turn clip coupled to a lamp base. Electrical connection is made through a duct traversing the bulb holder. By further enabling the bulb holder to lamp base coupling to be rotatable, the lamp pieces may be assembled in secure relation to each other in one operation, and quickly oriented in a second operation. An appropriate bond may be subsequently applied between the bulb holder and the lamp base to permanently fix the two pieces.
Abstract:
An automotive headlamp bulb provides the two light or three filament sources in a single bulb. One source may be used to generate a standard headlamp beam, while the second source may be used to generate an augmenting side beam in response to a turning signal. A similar third filament may provide an augmenting beam to the opposite side, or farther to the same side. The single bulb eliminates the need for a second bulb, or a second reflector in an advanced headlamp system with turning light augmentation.
Abstract:
A mechanical electrical connector for an electric lamp lead is disclosed. The connector is formed as a single piece from sheet metal and includes an electrical contact against which the lamp lead is pinched by an approximately perpendicularly extending clamp arm. The clamp arm may be further latched to lock the lead hard against the connector. The single piece connector yields an inexpensive, quickly attached, strong, and permanent mechanical support providing a secure electrical connection for an electric lamp lead.

Abstract:
A process of manufacture and an article produced by the process in the form of a lead glass substrate. The substrate is discretely marked during the manufacturing process by directing a flame upon it that is deficient in oxygen to provide a darkened or black marking in the glass surface. The invention is especially useful for marking electric lamps.
