In addition, since the lead wires 26 and 35 must be inserted into the protective tubes 27 and 36 during assembly, and the protective tubes 27 and 36 are stiff, they are difficult to bend and difficult to assemble.

An object of the present invention is to provide a lighting fixture that can be easily assembled and can reduce costs.

[0007]

[Means for Solving the Problems]

 The lighting device of the present invention has a main printed circuit board built into the upper part of the main body of the device, an auxiliary printed circuit board is attached to the lower panel of the lower part of the main device, and the main side connector of the main printed circuit board and the auxiliary side connector of the auxiliary printed circuit board are omitted. They are placed facing each other, a lead wire locking part is provided at a position apart from the auxiliary side connector on the lower panel, a lead wire for connecting the main side connector and the auxiliary side connector is provided, and the lead wire is provided at the center of the lead wire. It is locked in the locking part.

[0008]

[Action]

 According to the configuration of this invention, the main side connector and the auxiliary side connector are arranged substantially opposite to each other, the lead wire locking portion is provided at a position apart from the auxiliary side connector on the lower panel, and the central portion of the lead wire is provided. It is locked to the lead wire locking part. To attach the bottom panel of this lighting fixture to the fixture body, connect the main connector and auxiliary connector with lead wires, and lock the center of the lead wire with the lead wire locking part to omit the lead wire. The bottom panel should be attached to the equipment body in a letter shape. In this way, since the lower surface panel is attached after the lead wire is locked to the lead wire locking portion, the lead wire does not come into contact with the open end of the instrument body to which the lower surface panel is attached. As a result, it is not necessary to cover the lead wire with the protective tube, and the cost can be reduced. Also, since the lead wire not covered by the protective tube is easily bent, the bottom panel can be easily attached to the instrument body. Also, a long lead wire can be used, and the lead wire can easily connect the main connector and the auxiliary connector.
