That is, the power supply line 8a for supplying electric power and the ground line 32a for grounding the tubular lamp 60 are connected to the connector 8b, and these can be connected by one connector 8b. Therefore, it is possible to connect the power feeding unit 8 and the grounding unit 32 at once.
- the ground wire 32a is also housed in the housing recess 52 at the same time. It will be. Since the housing recess 52 is formed on the back side of the lamp body 1, it is possible to suppress the configuration of the power feeding unit 8 and the grounding unit 32 from protruding from or protruding from the outer shell of the lamp body 1. Wiring processing can be performed well.
- tubular lamp 70 according to a seventh embodiment will be described with reference to FIGS. Also here, the same reference numerals are given to components that function in the same manner as in the fifth embodiment described above, and detailed description thereof will be omitted.
- the tubular lamp 70 of the present embodiment is of a type that feeds power via the caps 6 at both ends of the lamp body 1, unlike the first to sixth embodiments described above. That is, the tubular lamp 70 is supplied with power through the terminal of the socket 102 in a state of being attached to the instrument main body 100 in the same manner as a conventional straight fluorescent lamp.
- the ground wire 32a of the grounding unit 32 is stored in the storage recess 52 in this embodiment.
- the storage recess 52 is provided on the back side of the lamp body 1.
- the grounding portion 32 on the lamp body 1 side includes a grounding wire 32a and a connector 32b.
- a base end portion of the ground wire 32a is fastened and fixed to the heat radiating portion 1b having conductivity in the lamp body 1 by screws or the like.
- the connector 32b of the grounding portion 32 on the lamp body 1 side is connected to the connector 112b provided at the tip of the grounding wire 112a drawn out from the fixture body 100.
- the ground terminal of the terminal block 110 electrically connected to the conductive heat radiating portion 1b is grounded via a ground wire (not shown). Therefore, the lamp body 1 is grounded via the ground wire 32a, the connector 32b, the ground wire 112a, the connector 112b, the heat radiating portion 1b, the terminal block 110, and the ground wire.
- the lead wire 32 is connected to the grounding portion 32 on the lamp body 1 side, the connector 32b, and derived from the fixture body 1 side.
- the grounding wire 112a and the connector 112b thus formed can be housed in the housing recess 52 provided on the back side of the lamp body 1. Thereby, it can suppress that the ground wire which connected the lamp
- a tubular lamp is not limited to a form compatible with a straight fluorescent lamp. It can also be configured in a form compatible with a single-end type fluorescent lamp. Further, the lighting device 108 that controls the lighting of the LED 2 may be disposed on the fixture body 100 side or the lamp body 1 side.
