  The present invention has been made in view of such a problem, and when a fixture main body is fixed to a mounting member fixed to a construction material such as a ceiling, a tensile force is applied to an electric wire without the user holding the fixture main body. An object of the present invention is to provide a lighting fixture that can prevent the lighting from being applied and can easily install the lighting fixture on the construction material.

  In order to achieve the above object, one aspect of a lighting fixture according to the present invention is a lighting fixture attached to a construction material, and irradiates illumination light with an attachment member for attaching the lighting fixture to the construction material. The instrument body having a light source and a first drive unit that drives the light source, and the first drive unit are fed by electric wires that transmit power supplied through the construction material, and the instrument body and the mounting member are The instrument body is connected to the attachment member so as to open and close in a bivalve shape.

  When fixing the instrument body to the mounting member fixed to the construction material, it is possible to suppress the tensile force from being applied to the electric wire without the user holding the instrument body, and to easily install the lighting equipment on the construction material. it can.

For example, although it is a VVF cable, it is not restricted to this.

[Functions of lighting equipment]
Next, an example of the illumination function and the ion emission function of the luminaire 1 when installed indoors will be described.

  When the illuminance sensor 142 determines that the illuminance around the luminaire 1 is lower than the threshold value and the human sensor 141 detects a person, the light source 120 starts by supplying DC power to the light source 120. Lights up automatically. The light from the light source 120 passes through the protective cover 123 and enters the translucent cover 150. The light that has entered the translucent cover 150 passes through the translucent cover 150 and is irradiated indoors. When a certain time has elapsed since the start of the supply of DC power to the light source 120, the supply of DC power to the light source 120 is stopped and the light source 120 is automatically turned off.

  In addition, when the blower fan 171 of the blower unit 170 rotates in a predetermined direction, the indoor air flows into the ventilation holes (first cover ventilation hole 310, first main body ventilation hole 115a, first case) serving as a suction port. The air is sucked into the instrument body 100 through the vent hole 161a) and the filter 350. That is, the outside air of the lighting fixture 1 is sucked into the support body 110. At this time, dust contained in the indoor air is collected by the filter 350.

  The air sucked into the appliance main body 100 is ventilated via the blower fan 171 as a vent (second case vent 161b, second main vent 115b, second cover vent 320). And is blown out of the instrument body 100. That is, the inside air of the lighting fixture 1 is blown out into the room.

  In the present embodiment, ions are generated by the ion generation unit 160 in conjunction with the rotation of the blower fan 171. Ions generated by the ion generation unit 160 are blown by the blower fan 171 through the vent holes (the third case vent hole 161c, the third main body vent hole 115c, and the second cover vent hole 320) that serve as blowout ports. Together with the air to be blown out of the instrument body 100. In other words, the ions generated by the ion generation unit 160 are blown out of the lighting fixture 1 while being assisted by the blowing of the blower fan 171, so that the ions can be diffused over a wide range in the room.

  In addition, the 1st drive unit 130 which drives the light source 120, and the 2nd drive unit 180 which drives the ventilation unit 170 and the ion production | generation unit 160 drive independently, respectively. In other words, while the air blowing unit 170 and the ion generation unit 160 are continuously driven for a predetermined time (for example, 8 hours), the light source 120 is turned on at an arbitrary timing independently of the air blowing unit 170 and the ion generation unit 160. It may turn off. The light source 120 may be turned on or off at an arbitrary timing by a user at an arbitrary timing by a wall switch or the like, instead of being automatically turned on and off by the illuminance sensor 142 and the human sensor 141.

[How to install lighting fixtures on the ceiling]
Next, the attachment method when attaching the lighting fixture 1 which concerns on this Embodiment to the ceiling 2 is demonstrated.

  As shown in FIGS. 7 and 8, when the lighting fixture 1 is attached to the ceiling 2, the attachment member 200 is fixed to the ceiling 2 in a state where the fixture body 100 and the attachment member 200 are connected. For example, the mounting member 200 that is a mounting plate is fixed to the ceiling 2 with screws or the like.

  At this time, since the hook portion 201 of the attachment member 200 is hooked in the through hole 113 of the instrument body 100, the instrument body 100 is temporarily held by the attachment member 200 in a state of being opened in a bivalve shape. That is, the instrument main body 100 is temporarily held by the attachment member 200 at one side fulcrum so as to be rotatable.

  Next, the electric wire 400 drawn from the opening 2 b of the ceiling 2 is connected to the power supply terminal block 190 of the instrument main body 100. At this time, since the instrument main body 100 is in an open state with respect to the mounting member 200, the electric wire 400 drawn from the opening 2 b of the ceiling 2 can be easily connected to the power terminal block 190 of the instrument main body 100. it can. In addition, when the operation of connecting the electric wire 400 to the power terminal block 190 is performed, the instrument body 100 and the mounting member 200 are connected, so that even if the user does not support the instrument body 100, a tensile force is applied to the electric wire 400. You can avoid that.

  Moreover, in this Embodiment, since the instrument main body 100 and the attachment member 200 are connected by the hanging string 500, the temporary holding state is maintained so that the instrument main body 100 may not open exceeding a fixed angle. That is, the opening angle of the instrument main body 100 is regulated by the hanging string 500, and when the instrument main body 100 is in the maximum open state with respect to the attachment member 200, a tensile force is applied to the hanging string 500. Thus, by using the hanging string 500, it is possible to prevent the tensile force from being applied to the electric wire 400.

  Next, the temporary holding state is released by rotating the instrument body 100 so as to close it, and the instrument body 100 is connected to the mounting member 200. Specifically, the instrument main body 100 is connected to the attachment member 200 such that the second screw hole 114b of the instrument main body 100 faces the second screw hole 220b of the attachment member 200. At this time, the first screw hole 114 a of the instrument main body 100 also faces the first screw hole 220 a of the attachment member 200.

  Next, as shown in FIG. 5, the second screw 116 b is inserted into the second screw hole 114 b of the instrument main body 100 and the second screw hole 220 b of the attachment member 200, and the second screw 116 b is screwed. The first screw 116a is inserted into the first screw hole 114a and the first screw hole 220a of the mounting member 200, and the first screw 116a is screwed. Thereby, the instrument main body 100 and the attachment member 200 can be fixed in a state where the instrument main body 100 is closed.

  Thereafter, the outer cover 300 is attached to the instrument body 100. Specifically, as shown in FIGS. 3 and 4, the three protrusions 340 provided on the inner surface of the outer cover 300 slide along the three guide grooves 117 provided on the outer surface of the support body 110. Then, each guide groove 117 is locked. More specifically, the outer cover 300 is moved in the ceiling side direction (Z-axis minus direction) so that each protrusion 340 slides on the first guide portion 117a of each guide groove 117, and then the outer cover 300 is moved. By rotating, each protrusion 340 is slid on the second guide portion 117b of each guide groove 117 and is locked to the inner end of the second guide portion 117b. Thereby, the outer cover 300 can be attached to the instrument main body 100.

  In addition, when removing the outer cover 300 from the instrument main body 100, the outer cover 300 is reversely rotated, and then the outer cover 300 is moved in the floor side direction (Z-axis plus direction), so that the outer cover 300 is moved to the instrument main body 100. Can be removed from.

[Summary]
Thus, in the lighting fixture 1 in this Embodiment, the fixture main body 100 is connected with respect to the attachment member 200 so that it may open and close in a bivalve shape.

  Thereby, when fixing the instrument main body 100 to the attachment member 200 fixed to the ceiling 2, the instrument main body 100 is held by the attachment member 200 in a state of being opened in a bivalve shape, so that the user holds the instrument main body 100. Even if it does not do, it can suppress that tensile force is applied to the electric wire 400. That is, no drop energy is applied to the electric wire 400.

  In particular, in the present embodiment, the instrument main body 100 includes not only the light source unit 11 and the first drive unit 130 but also the ion generation unit 160, the blower unit 170 (the blower fan 171), and the second drive unit 180. There is.

  For this reason, if the instrument main body 100 is not connected to the attachment member 200, if the user releases his / her hand from the instrument main body 100, the electric wire 400 may not be able to support the instrument main body 100 with only the electric wire 400, or the power source 400 may be disconnected. There is a risk of detachment from the table 190. On the other hand, in the luminaire 1 according to the present embodiment, even if the luminaire main body 100 is heavy, the luminaire main body 100 is connected to the attachment member 200 so as to open and close in a bivalve shape. Even if the hand is released from 100, it is possible to avoid the electric wire 400 from being disconnected or coming off the power supply terminal block 190.

  And since the user does not need to hold | maintain the instrument main body 100, the holding | maintenance weight burden of the user's instrument main body 100 at the time of construction can be reduced. Thereby, the connection operation | work to the instrument main body 100 of the electric wire 400 can be performed easily.

  Furthermore, since the instrument main body 100 is connected to the attachment member 200 so as to open and close in a bivalve shape, the instrument main body 100 is connected to the attachment member 200 at one fulcrum. Thereby, the position alignment in the part (screw fixing | fixed part) on the opposite side to the connection part (rotation fulcrum) of the instrument main body 100 and the attachment member 200 can also be performed easily. Therefore, the attachment work of the lighting fixture 1 to the ceiling 2 can be easily performed.

  As mentioned above, in the lighting fixture 1 in this Embodiment, when fixing the instrument main body 100 to the attachment member 200 fixed to the ceiling 2, even if a user does not hold | maintain the instrument main body 100, tensile force is applied to the electric wire 400. While being able to suppress, the lighting fixture 1 can be installed in the ceiling 2 easily.

  Moreover, in the lighting fixture 1 in the present embodiment, the fixture main body 100 and the attachment member 200 are connected in a bivalve shape by the hook portion 201 of the attachment member 200 being hooked in the through hole 113 of the fixture main body 100.

  Thereby, the instrument main body 100 and the attachment member 200 can be connected with a simple structure so that the instrument main body 100 can be opened and closed in a bivalve shape.

  Moreover, in the lighting fixture 1 in this Embodiment, the opening diameter is gradually increased on the inner surface of the first screw hole 114a of the side wall portion 112 in the fixture body 100 on the side opposite to the direction in which the first screw 116a is inserted. A tapered surface is formed. The first connecting piece 221 of the mounting member 200 is formed with a protruding portion 220a1 that protrudes from the peripheral edge of the first screw hole 220a of the first connecting piece 221 toward the second screw hole 114b.

  Thereby, when the instrument main body 100 opened in a cantilever state is rotated and closed, the protrusion 220a1 of the first connecting piece 221 of the mounting member 200 is tapered on the first screw hole 114a of the instrument main body 100. They are mated to follow. Thereby, alignment with the instrument main body 100 and the attachment member 200 can be easily performed by self-alignment.

  Moreover, the lighting fixture 1 in the present embodiment includes a hanging string 500 that connects the fixture body 100 and the mounting member 200, and the hanging strap 500 is in a state in which the fixture body 100 is open with respect to the mounting member 200. Sometimes a tensile force is applied. Specifically, the hanging string 500 has a length to which a tensile force is applied when the instrument main body 100 is open with respect to the attachment member 200.

  Thereby, it can prevent that the tensile force is applied to the electric wire 400 and the electric wire 400 is disconnected or disconnected. Moreover, the opening angle of the instrument main body 100 with respect to the attachment member 200 can be adjusted by changing the length of the hanging string 500.

(Embodiment 2)
