A plurality of elongated grooves 330 are formed. The plurality of grooves 330 are formed so as to be continuous with the plurality of slits constituting the first cover ventilation hole 310 and the second cover ventilation hole 320.

That is, as shown in the lower right enlarged view of FIG. 5, the outer cover 300 has a concave-convex shape in which a slit (first cover ventilation hole 310) serving as a through hole is formed, and is shown in the lower left enlarged view of FIG. As described above, a concave-convex shape in which a groove 330 that is not a through hole is formed is formed, and a uniform uneven shape is formed on the entire circumference of the side surface portion of the outer cover 300.

As a result, the groove portion 330 and the first cover ventilation hole 310 (second cover ventilation hole 320) appear to have a concavo-convex shape in which they are continuously integrated. Therefore, the first cover ventilation hole 310 is provided on the side surface of the outer cover 300. And the formation of the second cover vent 320 can be made inconspicuous. That is, the user is less likely to notice that the outer cover 300 is formed with through holes (first cover ventilation hole 310, second cover ventilation hole 320).

By forming continuous grooves in the first cover vents 310 and the second cover vents 320 in this way, the first cover vents 310 do not impair the appearance design of the luminaire 1. And a second cover vent 320 can be formed.

Further, by making the first cover ventilation holes 310 and the second cover ventilation holes 320 into slits to form an uneven shape in a cross-sectional view, when looking up at the lighting fixture 1 arranged above, the first cover passage is passed. The pores 310 and the second cover vent 320 can be obscured.

The outer cover 300 configured in this way is detachably attached to the instrument main body 100. Specifically, the outer cover 300 is detachably attached to the side wall portion 112 of the support main body 110.

In the present embodiment, as shown in FIGS. 3 and 4, three protrusions 340 are provided on the inner surface of the outer cover 300, and these three protrusions 340 are provided on the outer surface of the support main body 1103.

The three protrusions 340 are provided at intervals of 120 ° along the circumferential direction of the outer cover 300 so as to face each other across the center of the outer cover 300, but the number of protrusions 340 and the spacing between the arrangement of the protrusions 340 are different. , Not limited to this. Of the three protrusions 340, one protrusion 340 is separated into two.

Further, as shown in FIGS. 3 to 7, a filter 350 is attached to the inside of the outer cover 300. The filter 350 is detachably attached to the inside of the side surface of the outer cover 300. Further, the filter 350 covers the first cover ventilation hole 310 of the outer cover 300.

The filter 350 is a dust collecting filter. The outside air sucked by the blower unit 170 passes through the filter 350. That is, the filter 350 mainly collects dust contained in the air in the indoor space region. By passing the outside air through the filter 350 in this way, the dust contained in the outside air can be adsorbed on the filter 350 and the dust can be removed from the air.

In the present embodiment, the filter 350 has a grid-like horizontally long rectangular frame 351 having a plurality of openings, and a mesh filter 352 provided on the frame 351 so as to cover the plurality of openings of the frame 351. ..

The filter 350 is arranged between the outer cover 300 and the support main body 110 of the instrument main body 100. Specifically, the filter 350 is arranged between the first cover ventilation hole 310 of the outer cover 300 and the first main body ventilation hole 115a of the support main body 110 (side wall portion 112). The first cover ventilation hole 310 and the first main body ventilation hole 115a communicate with each other via a filter 350. That is, the external space (indoor space) of the outer cover 300 and the internal space of the instrument main body 100 are spatially connected via the first cover ventilation hole 310, the filter 350, and the first main body ventilation hole 115a. As a result, when the outside air sucked through the first cover ventilation hole 310 by the blower unit 170 passes through the filter 350, the dust contained in the outside air is removed by the filter 350.

In the present embodiment, the filter 350 covers the first cover ventilation hole 310 which is the suction port, but does not cover the second cover ventilation hole 320 which is the air outlet.

Further, as shown in the lower right enlarged view of FIG. 5, the frame body 351 (lattice portion) of the filter 350 is arranged so as not to overlap with the first cover ventilation hole 310 of the outer cover 300. That is, the frame body 351 of the filter 350 is arranged on the back side of the portion (frame portion) of the outer cover 300 where the first cover ventilation hole 310 is not formed. That is, the frame 351 of the filter 350 is hidden in the portion of the outer cover 300 where the first cover vent 310 is not formed. Thereby, the design of the appearance of the luminaire 1 can be improved.

[Electrical wire]
The electric wire 400 is a power supply line that transmits the electric power supplied through the ceiling 2 to the luminaire 1. The electric wire 400 supplies AC power from the system power supply to the luminaire 1. In the present embodiment, the electric wire 400 is pulled out from the ceiling of the ceiling 2 through the opening 2b of the ceiling 2 and the opening 210a of the mounting member 200 into the instrument main body 100 and connected to the power terminal block 190 of the instrument main body 100. Has been done. As a result, the AC power from the system power source transmitted by the electric wire 400 is supplied to the first drive unit 130 via the power terminal block 190. For example, it is a VVF cable, but it is not limited to this.

[Function of lighting equipment]
Next, an example of the lighting function and the ion emission function of the lighting fixture 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 motion sensor 141 detects a person, the light source 120 is started to supply 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 incident on the translucent cover 150 passes through the translucent cover 150 and is irradiated into the room. After a certain period of time has passed since the supply of the DC power to the light source 120 was started, the supply of the DC power to the light source 120 was stopped and the light source 120 was automatically turned off.

Further, when the blower fan 171 of the blower unit 170 rotates in a predetermined direction, the air in the room is sucked into the ventilation holes (first cover ventilation hole 310, first main body ventilation hole 115a, first case). It is sucked into the inside of the instrument body 100 through the ventilation hole 161a) and the filter 350. That is, the outside air of the luminaire 1 is sucked into the support main body 110. At this time, the dust contained in the indoor air is collected by the filter 350.

The air sucked into the instrument body 100 passes through the blower fan 171 and serves as an air outlet (second case vent 161b, second body vent 115b, second cover vent 320). Through, it is blown out to the outside of the instrument body 100. That is, the inside air of the lighting fixture 1 is blown 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. The ions generated by the ion generation unit 160 are blown by the blower fan 171 through the ventilation holes (third case ventilation holes 161c, third main body ventilation holes 115c, second cover ventilation holes 320) that serve as air outlets. It is blown out to the outside of the instrument body 100 together with the air. That is, the ions generated by the ion generation unit 160 are blown out to the outside of the luminaire 1 while being assisted by the blown air of the blower fan 171. Therefore, the ions can be diffused over a wide range in the room.

The first drive unit 130 that drives the light source 120 and the second drive unit 180 that drives the blower unit 170 and the ion generation unit 160 are driven independently of each other. That is, while the blower 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 or turned on at an arbitrary timing independently of the blower unit 170 and the ion generation unit 160. It may be turned off. The light source 120 may be turned on or off at an arbitrary timing by the user by a wall switch or the like, instead of being automatically turned on and off by the illuminance sensor 142 and the motion sensor 141.

[How to attach the lighting equipment to the ceiling]
Next, an attachment method when attaching the lighting fixture 1 according to the present embodiment to the ceiling 2 will be described.

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

At this time, since the hooking portion 201 of the mounting member 200 is hooked in the through hole 113 of the instrument body 100, the instrument body 100 is temporarily held by the mounting member 200 in a state of being opened like a bivalve. That is, the instrument body 100 is rotatably and temporarily held by the mounting member 200 at a fulcrum on one side.

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

Further, in the present embodiment, since the instrument body 100 and the mounting member 200 are connected by the suspension string 500, the temporary holding state is maintained so that the instrument body 100 does not open beyond a certain angle. That is, the opening angle of the instrument body 100 is regulated by the suspension string 500, and when the instrument body 100 is in the state of being opened to the maximum with respect to the mounting member 200, a pulling force is applied to the suspension string 500. In this way, by using the suspension string 500, it is possible to prevent the electric wire 400 from being subjected to a tensile force.

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 body 100 is connected to the mounting member 200 so that the second screw hole 114b of the instrument body 100 faces the second screw hole 220b of the mounting member 200. At this time, the first screw hole 114a of the instrument body 100 also faces the first screw hole 220a of the mounting member 200.

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

After that, 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 main body 110. And lock it in each guide groove 117. 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 locked to the inner end portion of the second guide portion 117b. As a result, the outer cover 300 can be attached to the instrument main body 100.

When removing the outer cover 300 from the instrument main body 100, the outer cover 300 is rotated in the reverse direction, and then the outer cover 300 is moved in the floor side direction (Z-axis plus direction) to move the outer cover 300 to the instrument main body 100. Can be removed from.

[Summary]
As described above, in the lighting fixture 1 of the present embodiment, the fixture body 100 is connected to the mounting member 200 so as to open and close in a bivalve shape.

As a result, when the instrument body 100 is fixed to the attachment member 200 fixed to the ceiling 2, the instrument body 100 is held by the attachment member 200 in a state of being opened like a bivalve, so that the user holds the instrument body 100. Even if this is not done, it is possible to suppress the application of tensile force to the electric wire 400. That is, no falling energy is applied to the electric wire 400.

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

Therefore, if the instrument body 100 is not connected to the mounting member 200, if the user releases the instrument body 100, the instrument body 100 cannot be supported by the electric wire 400 alone, and the electric wire 400 may be disconnected or the power supply terminal may be disconnected. There is a risk that it will come off the table 190. On the other hand, in the lighting fixture 1 of the present embodiment, even if the fixture body 100 is heavy, the fixture body 100 is connected to the mounting member 200 so as to open and close in a bivalve shape, so that the user can use the fixture body. Even if the hand is released from 100, it is possible to prevent the electric wire 400 from being disconnected or detached from the power terminal block 190.

Moreover, since the user does not have to hold the instrument body 100, it is possible to reduce the burden on the user's instrument body 100 during construction. As a result, the work of connecting the electric wire 400 to the instrument main body 100 can be easily performed.

Further, since the instrument body 100 is connected to the attachment member 200 so as to open and close in a bivalve shape, the instrument body 100 is connected to the attachment member 200 at a fulcrum on one side. As a result, it is possible to easily align the device main body 100 and the mounting member 200 at a portion (screw fixing portion) opposite to the connecting portion (rotation fulcrum). Therefore, the work of attaching the luminaire 1 to the ceiling 2 can be easily performed.

As described above, in the lighting fixture 1 of the present embodiment, when the fixture body 100 is fixed to the mounting member 200 fixed to the ceiling 2, a tensile force is applied to the electric wire 400 even if the user does not hold the fixture body 100. It can be suppressed, and the lighting fixture 1 can be easily installed on the ceiling 2.

Further, in the lighting fixture 1 of the present embodiment, the fixture body 100 and the mounting member 200 are connected in a bivalve shape by hooking the hooking portion 201 of the mounting member 200 into the through hole 113 of the fixture body 100.

Thereby, with a simple structure, the instrument body 100 and the mounting member 200 can be connected so that the instrument body 100 can be opened and closed like a bivalve.

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

As a result, when the instrument body 100 in the cantilevered open state is rotated and closed, the protruding portion 220a1 of the first connecting piece 221 of the mounting member 200 is a tapered surface of the first screw hole 114a of the instrument body 100. It is fitted so that it follows. As a result, the alignment of the instrument body 100 and the mounting member 200 can be easily performed by self-alignment.

Further, the lighting fixture 1 according to the present embodiment includes a hanging string 500 for connecting the fixture body 100 and the mounting member 200, and the hanging strap 500 is in a state where the fixture body 100 is open with respect to the mounting member 200. Sometimes pulling force is applied. Specifically, the suspension string 500 has a length to which a pulling force is applied when the instrument main body 100 is open with respect to the mounting member 200.

As a result, it is possible to prevent the electric wire 400 from being disconnected or detached due to a tensile force applied to the electric wire 400. Further, the opening angle of the instrument body 100 with respect to the mounting member 200 can be adjusted by changing the length of the hanging string 500.

Note that FIGS. 9 and 12 show only a cross-sectional portion of the luminaire 1A. Further, FIGS. 11 and 12 show a state before the outer cover 300 is attached, but FIG. 12 further omits the outer cover 300.

As shown in FIGS. 9 to 12, the luminaire 1A according to the present embodiment includes the luminaire main body 100, the mounting member 200A, and the outer cover 300, similarly to the luminaire 1 according to the first embodiment.

The luminaire 1 in the first embodiment is directly attached and fixed to the ceiling surface 2a of the ceiling 2, whereas the luminaire 1A in the present embodiment is a hook ceiling installed in the opening 2b of the ceiling 2. It is connected and fixed to 3. The hook ceiling 3 is connected to the system power supply by an electric wire or the like.

The luminaire 1A according to the present embodiment has a different mounting member 200A from the luminaire 1 according to the first embodiment. Specifically, in the luminaire 1 of the first embodiment, the mounting member 200 is composed of only the mounting plate, but in the luminaire 1A of the present embodiment, the mounting member 200A is the connecting plate 210A.
