Abstract:
A method for producing a lamp, comprising mounting a sleeve (9) onto a lead wire (6) drawn out of an eyelet (5a) of a base (5) of a lamp; and fusing the lead wire and the sleeve with the eyelet by plasma arc welding.
Abstract:
A method for producing a lamp includes forming a tubular portion (5d) that is protruded in an end of an eyelet (5a) of a base (5) of a lamp; drawing a lead wire (6) for supplying power out of the tubular portion (5d); and fusing the lead wire (6) and the tubular portion (5d) with the eyelet (5a) by plasma arc welding. This ensures that plasma arc can be discharged to the protruded tubular portion(5d) , and therefore the tubular portion and the lead wire are fused with the eyelet of the base satisfactorily and stably. In the present invention, a tubular sleeve can be used in place of the tubular portion (5d).
Abstract:
An electronic component contained in a metal case (2) is attached with an insulation base (7) at a sealing part and lead wires (4) of the electronic component element are passing through holes on the insulator base (7), and the end parts of the lead wires (4a) are bent in recesses (8b) on the insulator base (7) thereby constituting surface mounting type electronic component.
Abstract:
To provide a bulb-form lamp including a few compartments, which can be easily fitted in a socket of a lighting equipment and reliably carry out electrical contact between a shell and the socket of the lighting equipment. The bulb-form lamp includes a shell (8) surrounding one end of a casing (2), and the shell (8) is molded integrally with one end of the casing (2) to make contact with an outer surface of the casing (2) leaving substantially no gap.
Abstract:
Without applying soldering or plasma arc welding, a lead wire is brought into connection with an eyelet easily and reliably so that lighting failure due to incomplete contact is prevented and cost saving is achieved. A base (7) has a screw form shell (8) and an eyelet (9). An end portion of the shell (8) is provided with the eyelet (9) via an insulator. A lead wire (11a) supplying power is brought into connection with a portion of the eyelet (9) at other than an outer surface of the eyelet.
Abstract:
A bulb-form lamp allows a lighting circuit and an eyelet to be easily and reliably connected together without using any soldering or plasma arc welding or lead wires, prevents a lighting failure caused by an inappropriate contact, and reduces costs while improving productive efficiency. The bulb-form lamp comprising a case (12) having a lighting circuit (10) accommodated inside and a base (13) formed at an end portion of the case and having an eyelet (11) and a screw-like shell (9). The lighting circuit (10) and the eyelet (11) are connected together without any lead wire.
