Description

[Detailed Description of the Invention] This invention relates to a lighting device using a fluorescent lamp.

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 conductive part and a circuit part that face into each wiring part and act as a contact piece or a switch contact are provided on the other side of the board. A conductive plate formed in a series is disposed, and a second substrate covers the conductive plate so that undesired charged parts are not exposed, and holds the conductive plate together with the first substrate. It is something.

However, in such a configuration,
A first board as a main component constituting wiring components separately from the case body constituting the outer shell of the lighting fixture,
Three types of parts are required: a second board and a conductive plate, and the number of parts is large, and the above wiring parts must always be prepared as one completed intermediate part when assembling the lighting equipment. A large inventory space was required, and inventory management was also troublesome. Further, since the conductive plate is fixed only after being sandwiched between the first substrate and the second substrate, it is only placed on the first substrate before being sandwiched.
For this reason, during the clamping process, there is a possibility that your hands may touch the conductive plate or the lamp socket connected to it, or that the conductive plate may come into contact with the protrusions on the second board, causing the conductive plate to shift its position. The drawback was that it was necessary and difficult to work with.

This idea was made in view of the above points, and includes a plurality of pairs of conductive plate locking walls facing each other at a predetermined interval on the side of the case formed of an insulating material, and one conductive plate disposed inside the case body. The number of parts is reduced by providing corresponding locking pieces on multiple circuit parts and the conductive plate locking wall, and by pushing the conductive plate into the bottom side of the case, the locking pieces are elastically locked on the conductive plate locking wall. less,
To provide a lighting device that can easily be produced in an integrated manner from basic parts such as a conductive plate to assembly of the lighting device, does not require special intermediate parts, and allows easy positioning and fixing of the conductive plate during assembly.
