[Problems to be solved by the device]

In the above-described lighting fixtures, lighting components such as ballasts and lamp sockets are connected by wiring with lead wires, and a single-ended fluorescent lamp is used as a light source in a lighting fixture that uses a high-frequency lighting device. In the case of using, if the wiring is simply routed as in the prior art example described above, some lead wires may cross the output electric wire from the high-frequency lighting device and the power input electric wire, or may be adjacent and parallel to each other. The high frequency of the output wire may cause noise interference in the power supply line and damage other electrical equipment.It is necessary to take measures against noise, which complicates wiring, impairs assembly workability, and impairs the appearance. There was a problem such as.

The present invention has been made in view of the background described above, and an object of the present invention is to provide a lighting fixture capable of reducing noise and improving assembly workability and aesthetics.

[Means for Solving the Problems]

The lighting fixture according to the present invention is a lighting fixture in which lighting components such as a high-frequency lighting device and a lamp socket are arranged in a lighting fixture body, and the lighting components are connected to each other to form a lighting circuit. A lamp socket provided with a connecting terminal for connecting a connector to be drawn out in a direction substantially orthogonal to the lamp axis is arranged from one side of the lighting fixture body, and a single base fluorescent lamp is attached to the lamp socket for connection. The high-frequency lighting device is arranged so that the output terminal portion having the terminal is closer to the lamp socket and the central axis is substantially parallel to the lamp axis of the single-ended fluorescent lamp, and the connection terminal of the lamp socket and the connection terminal of the high-frequency lighting device are connected. It is connected with a connector.

After rotating the luminaire main body 1 through the circular hole and tightening the mounting screw 5 to push the luminaire main body 1 to the mounting surface, so-called simple mounting without electrical work inside the house can be performed. There is.

The high frequency lighting devices 2 and 2'have a substantially rectangular outer shape,
One of the longitudinal ends of the lighting fixture main body 1 is set so that the longitudinal direction thereof is substantially parallel to the lamp axis of the single base fluorescent lamp 6 mounted on the lamp socket 3 between two different portions of the single base fluorescent lamps 6. They are attached to each side. The high-frequency lighting devices 2 and 2 ′ are provided with output terminal portions 21 and 21 ′ that supply an output to the lamp socket 3 at one longitudinal end of the lighting fixture main body 1 which is close to one side. Output terminal block 21, 2
1'is formed with a groove portion into which an electric wire can be inserted and held along the longitudinal direction of the high-frequency lighting device 2, 2 ', and pressure contact terminals 22, 22' as connection terminals are provided in the groove portion.

The lamp socket 3 includes a connection terminal portion 31 to which the outputs of the high frequency lighting devices 2 and 2 ′ are connected, and a lamp holder portion 32 that holds the single-ended fluorescent lamp 6, and the connection terminal portion 31 surrounds the luminaire main body 1. Three pieces are arranged side by side from the lower surface 1 side of the luminaire main body 1 on the edge side. A single base fluorescent lamp 6 is mounted on the lamp socket 3 with their lamp axes substantially parallel to each other, and a support spring 7 made of a stainless steel thin plate attached to the other side of the lower surface of the lighting fixture body 1 has a single base. It holds the tip of the fluorescent lamp 6. The connection terminal portion 31 of the lamp socket 3 is formed with a groove portion into which an electric wire can be inserted and held along a direction orthogonal to the lamp axis of the single-base fluorescent lamp 6 attached to the lamp socket 3, and the connection portion is connected to the groove portion. A pressure contact terminal 33 as a terminal is provided.

The connecting tools 8 and 9 include insulating portions 81 and 91 formed of an insulating material such as thermoplastic resin, and a plurality of connecting conductors which are covered with the insulating portions 81 and 91 and maintain a positional relationship. 82, 92
It has become. The connecting conductors 82 and 92 of the connecting tools 8 and 9 are
It is formed so as to be connectable to the press contact terminals 22, 22 'of the high frequency lighting devices 2, 2'and the press contact terminal 33 of the lamp socket 3, respectively.

The high-frequency lighting device 2 for two lamps and the lamp sockets 3 on both sides thereof are connected to each other by the connecting tool 8 so that the high-frequency lighting device 2 for one lamp 2 '
The remaining lamp socket 3 and the remaining lamp socket 3 are connected by a connecting tool 9 to form a lighting circuit on the output side of the high frequency lighting device. The power supply wire 10 from the hook ceiling cap 4 is connected to the high frequency lighting device 2'for one lamp at the end opposite to the output terminal portion 21 'in the longitudinal direction. From the end opposite to the output terminal portion 21 'to which the power supply wire 10 of the high frequency lighting device 2'for one lamp is connected is provided as a power supply line for supplying power to the high frequency lighting device 2 for two lights.
