摘要:
Manufacturing equipment and manufacturing process steps that improve upon prior art processes for the manufacturing of filament tube and arc tube light sources, their components and subassemblies, and lamps employing said light sources. A double ended, tipless filament tube or arc tube light source incorporates a drawn-down tubular body, and one piece foliated leads with spurs for process handling and for spudding into a filament with stretched-out legs. Bugled ends on the body provide a novel cutoff means, facilitate a flush-fill finishing process, and enhance mounting and support of the light sources in lamps. The foliated leads are made from a continuous length of wire in a process including foil hammering and two-bath AC electrochemical etching. Cost-reduced light source and lamp production enables affordable household consumer lamps, even when containing two series-connected halogen filament tubes. Safety benefits ensue from series connection, especially in combination with disclosed body and filament constructions.

A method for manufacturing a baseless incandescent lamp assembly comprises a step for molding a conductive plate material into a continuous holding member chain including a number of facing pairs of holding members on both sides of a belt-like coupling section, a holding step for causing a flattened seal section of a baseless incandescent lamp to be held between the paired holding members, a step for cutting off the paired holding members from the coupling section while keeping the flattened seal section of the baseless incandescent lamp between the holding members, and a step for inserting the holding members holding the flattened seal section of the baseless incandescent lamp therebetween into a lamp holding chamber of a main socket body, thereby fixing the holding members to said main socket body.

摘要:
An electrical device with an elongated tubular envelope has an incandescent filament supported along the axis of the envelope by ceramic plates mechanically bonded to the filament and fitting closely in the envelope. The plates may be interconnected by a link rod parallel to the filament which is a single-ended lamp serves also as a lead to one end of the filament.

A lamp cap (100) comprising a base part (101) defining a cavity (102) for receiving a socket (203) of a lamp, the base part (101) having a lateral wall arrangement (103) limiting the cavity (102) and a ring shaped bottom side (104) surrounding an aperture (105); an electrical insulating interface (106) fixed to the bottom side of the base part (104) in such a manner that it covers the aperture (105), a space (102) being defined between the electrical insulating interface (106) and the lateral wall arrangement (103); and an electrical connector assembly (120) extending through the electrical insulating interface (106) to provide an electrical connection between the lamp socket (203) and an electrical power supply. A method of and apparatus for manufacturing a lamp cap is also described.
摘要:
The electric lamp has a lamp vessel (10) having a pinch (12) mounted in an outer envelope (1) by means of a clamping member (20) of metal sheet which is present on the pinch (12). The clamping member (20) has an open loop (21) which extends in a direction transverse to the broad side faces (13, 14) of the pinch (12). A still open clamping member (20), when present around the pinch (12), can easily be fastened by plastically deforming a specified region of the member by the method of the invention.
摘要:
A programmable thermal sensor is implemented in an integrated circuit such as a microprocessor. The programmable thermal sensor monitors the temperature of the integrated circuit, and generates an output to indicate that the temperature of the integrated circuit has attained a pre-programmed threshold temperature. In a microprocessor implementation, the microprocessor contains a processor unit, an internal register, microprogram and clock circuitry. The microprogram writes programmable input values, corresponding to threshold temperatures, to the internal register. The programmable thermal sensor reads the programmable input values, and generates an interrupt when the temperature of the microprocessor reaches the threshold temperature. In addition to a programmable thermal sensor, the microprocessor contains a fail safe thermal sensor that halts operation of the microprocessor when the temperature attains a critical temperature.
摘要:
An apparatus for manufacturing a bulb comprising a mount head including first and second pairs of lead-in wire holes alternately formed in a straight line, a first support mechanism capable of fixing in place lead-in wires inserted in the first pair of lead-in wire holes, and a second support mechanism capable of fixing in place lead-in wires inserted in the second pair of lead-in wire holes, a support mechanism for removably supporting the mount head in a predetermined position, an air cylinder for selectively driving the first and second mechanisms to fix the lead-in wires to predetermined positions relative to the mount head, locating plate on which one end of each lead-in wire inserted in each lead-in wire hole of the mount head abuts, whereby the position of one end relative to the mount head is defined, and an air cylinder capable of engaging the lead-in wires inserted in the first pair of lead-in wires to move the lead-in wires axially toward the mount head.
