Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a lighting fixture using a fluorescent lamp or the like.

Conventionally, in this type of lighting equipment, wiring parts such as a starter socket and a switch are assembled together with a ballast into a case of the lighting equipment, and a reflector is attached to cover the bottom surface of the case. Some of the wiring parts such as a starter socket and a switch incorporated in the case are unitized as shown in, for example, Japanese Utility Model Application Publication No. 56-153022. That is, each wiring component is integrally provided on one side of a first board made of an insulating material, and a plurality of thin conductive parts and a plurality of thin conductive parts facing into each wiring component and acting as contact pieces or switch contacts are provided on the other side of the board. A conductive plate having a series of circuit parts connected by connecting parts is disposed, and a second board is provided which covers the conductive plate so that undesired live parts are not exposed, and which holds the conductive plate with the first board. The lighting circuit of the lighting equipment is formed by cutting the plurality of connecting parts and separating each circuit part.

However, in such a configuration,
In order to form a lighting circuit for a lighting device, it is necessary to cut and separate the connecting portions of the conductive plates. As a method of cutting and separating, if the connecting portion is cut before disposing the conductive plate on the first substrate, the number of parts of the single conductive plate increases, and assembly becomes extremely troublesome. On the other hand, it is easy to incorporate the conductive plate by disposing the conductive plate on the first substrate, covering it with the second substrate, and then cutting the connection part. It is necessary to provide a through hole for inserting a cutting punch and a die, which has the drawback that the live parts are exposed through the through hole and the strength of the first and second substrates is weakened by the through hole. Ta. Furthermore, the shapes of the first and second substrates are limited, and there is a drawback that they cannot be used particularly as design parts or parts constituting an exterior.

This invention was made in view of the above points, and includes a case body made of synthetic resin and provided with a plurality of cutting receiving parts, a plurality of circuit parts constituting an electric circuit, and a case body that connects the circuit parts and has one side narrow. A series of approximately triangular connecting parts are formed as cutting parts, and a conductive plate is provided in the vicinity of the cutting parts to be supported by the cutting receiving part and attached to the case body, and the cutting part is used as a die to connect the connecting parts. By cutting the cut portion of the part with a punch and separating the circuit parts, assembly is easy, the live parts are not exposed, and the strength of the first board and the second board is high. An object of the present invention is to provide a method for manufacturing a lighting device with a good appearance, in which the substrate or the second substrate can be used as a design component or a case body constituting an outer shell.

76 is a cord locking piece that is locked to the round cord 175, and 177 is a cord hanger through which the round cord 175 is inserted, and is used to adjust the hanging height from the ceiling. The cord hanger 177 is engaged with the cord cover engagement hole 152 of the case 140. 178 is a cord locking tool for locking the round cord 175, and 179 is a hook rosette connected to the tip of the round cord 175.

Since the present invention is configured as described above, it is possible to provide a method for manufacturing a lighting fixture that is easy to assemble, does not expose the charging part, has high strength, and has a good appearance of the case body.
