FIG. 2 is a perspective view of the appearance of the lighting fixture 300 according to the embodiment when viewed from above. FIG. 3 is a schematic diagram showing the third terminal 323 of the lighting fixture 300 according to the implementation mode. In addition, FIGS. 1 and 2 illustrate a suspended ceiling lamp socket main body 200 provided on a structure such as a ceiling, and a lighting equipment kit 400 including the suspended ceiling lamp socket main body 200 and lighting equipment 300.

As shown in FIGS. 1 and 2, the lighting fixture 300 includes a fixture housing 315, a light emitting unit 320, a bulb 350, a first terminal 321 and a second terminal 322 for power supply, and a plurality of third terminals 323 for grounding. Two third terminals 323 are shown in FIG. 2.

The appliance housing 315 has: a first surface 315a that faces the suspended ceiling lamp holder main body 200; and a second surface 315b opposite to the first surface 315a. The appliance case 315 is made of, for example, metal and has conductivity. When viewed from a direction perpendicular to the first surface 315a, the appliance housing 315 is circular. In the appliance housing 315, terminal insertion holes 316a and 316b are provided at positions corresponding to the first terminal 321 and the second terminal 322, respectively. In addition, in the appliance housing 315, four terminal insertion holes 316c are provided at positions corresponding to the two third terminals 323, respectively. The four terminal insertion holes 316c are provided in a group of two.

The light-emitting part 320 is a light source having a plurality of LEDs inside, and emits light toward the lamp ball 350 (downward), for example. The light emitting part 320 is provided on the second surface 315b side of the appliance housing 315.

The lamp ball 350 is an optical member with translucency, and the shape of the lamp ball 350 when viewed from above is circular. The lamp ball 350 is installed on the second surface 315b of the appliance housing 315 in a manner to cover the light emitting part 320.

The first terminal 321 and the second terminal 322 are, for example, metal plate-shaped members, and the cross section thereof is L-shaped. The first terminal 321 is inserted into the terminal insertion hole 316a of the device housing 315, and a part thereof protrudes outward (upward) from the first surface 315a. The second terminal 322 is inserted into the terminal insertion hole 316b of the appliance housing 315, and a part thereof protrudes outward (upward) from the first surface 315a. The other end of each of the first terminal 321 and the second terminal 322 is electrically connected to the light emitting part 320.

In order to prevent each of the first terminal 321, the second terminal 322 and the appliance housing 315 from conducting each other, insulation is provided between the first terminal 321 and the terminal insertion hole 316a, and between the second terminal 322 and the terminal insertion hole 316b. Components are also possible. In addition, the inner peripheral surface of each terminal insertion hole 316a, 316b may be covered with an insulating member.

As shown in FIG. 3, the third terminal 323 is a linear member made of metal, and is formed into a U-shape bent. In the third terminal 323, two terminal insertion holes 316c are inserted at both ends, and the center part protrudes outward (upward) from the first surface 315a of the appliance housing 315. Both ends of the third terminal 323 are further bent to contact the appliance housing 315 and are electrically connected to the appliance housing 315. The third terminal 323 has elasticity and is elastically deformed because it receives a force in a direction perpendicular to the first surface 315a.

In addition, the two third terminals 323 are provided at positions corresponding to the grounding portion 223 of the suspended ceiling lamp holder body 200 described later. When viewed from a direction perpendicular to the first surface 315a, the two third terminals 323 are arranged in a rotationally symmetric manner. That is, the two third terminals 323 are arranged at equal angular intervals with the center 315c of the appliance housing 315 as a reference. Two third terminals 323 are shown in FIG. 2, but more than three third terminals 323 may be provided in the lighting device 300.

In addition, the two terminal insertion holes 316c in a group are arranged along the tangent line in the rotation direction when the luminaire 300 is rotated and mounted on the suspended ceiling lamp holder main body 200, and the linear third terminal 323 follows It is arranged to include the predetermined surface of the tangent.

The predetermined angle is, for example, 30° or more and 60° or less.

The lighting fixture 300 of this embodiment further includes a third terminal 323 for grounding, which is different from the first terminal 321 and the second terminal 322 for power supply. The third terminal 323 is electrically connected to the appliance housing 315.

Since the luminaire 300 has the above structure, when the luminaire 300 is connected to the suspended ceiling lamp holder main body 200, the luminaire housing 315 can be grounded to improve the safety of the luminaire 300.

[2. Combination structure of luminaire and main body of suspended ceiling lamp holder] Next, the combined structure of the luminaire 300 and the suspended ceiling lamp holder main body 200 will be described with reference to FIGS. 4A and 4B.

4A is a schematic diagram before installing the lighting fixture 300 according to the implementation aspect to the main body 200 of the suspended ceiling lamp holder.
