The second lower control unit 52d is connected to the second lower light emitting unit 52c via the second lower illumination wiring 152. As shown in FIG.

Therefore, the power supplied to the power cable 102 is distributed to the upper lighting fixture 30 , the first lower lighting fixture 55 and the second lower lighting fixture 56 . As a result, the upper lighting fixture 30, the first lower lighting fixture 55, and the second lower lighting fixture 56 are prevented from not lighting or becoming unstable due to insufficient current specifications.

A relay harness 160 is connected to the signal connector 322 in the upper control unit 32 . The signal connector 322 is an example of a "connector". The relay harness 160 has a plurality of connectors for connecting to various electric devices.

The first relay wiring 161 is connected to one end of the upper lighting wiring 141 . The other end of the upper lighting wiring 141 is connected to the upper light emitting unit 41 . The second relay wiring 162 is connected to one end of the first downstream signal line 131 . The other end of the first downstream signal line 131 is connected to a wiring 191 connected to the first lower control unit 51d. The third relay wiring 163 is connected to one end of the second downstream signal line 132 .

Therefore, the upper control unit 32 switches between supply and non-supply of power to the upper light emitting unit 41 based on the signals received from the first and second sensor switches 51b and 52b, and switches the received signals between the first and second sensor switches 51b and 52b. It can be transmitted to the lower control units 51d and 52d.

The procedure for attaching the lighting device 8 will be described with reference to the drawings shown in FIGS. 7 to 10. FIG. In FIG. 8, illustration of the pilot hole 29 is omitted. As shown in FIG. 7, the worker assembles the combined cabinet 20 by connecting the first mirror cabinet 21 and the second mirror cabinet 22 .

The operator attaches the first lower unit 51 to the bottom surface of the first mirror cabinet 21 and attaches the second lower unit 52 to the bottom surface of the second mirror cabinet 22 .

The operator pulls out the wiring 182 and the wiring 192 to the front side of the second mirror cabinet 22 . The first and second lower units 51 , 52 may be attached to the first and second mirror cabinets 21 , 22 prior to assembly of the composite cabinet 20 .

A worker fixes the harness connector 103 and the branch connector 104 to the composite cabinet 20 . A worker connects the power cable 102 to the harness connector 103 . An operator connects the harness connector 103 and the branch connector 104 via the relay wire 105 for power supply. The operator connects upper power line 111 , first lower power line 112 and second lower power line 113 to branch connector 104 .

The worker connects the first upstream wiring 121 to the wiring 181 . The worker connects the first downstream signal line 131 to the wiring 191 . The worker connects the second upstream signal line 122 to the wiring 182 . The worker connects the second downstream signal line 132 to the wiring 192 .

The operator temporarily attaches the power cable 102 to the rear surface of the second mirror cabinet 22 using the tape TP. This is preparation for pulling out the power cable 102 to the upper surface 20a of the composite cabinet 20 through the first recess 21g.

The operator temporarily attaches the upper power line 111, the first upstream signal line 121, and the first downstream signal line 131 to the rear surface of the first mirror cabinet 21 using tape TP. This is a preparation for drawing out these three wires from the second recess 21f to the upper surface 20a of the composite cabinet 20. FIG. The operator temporarily attaches the second upstream signal line 122 and the second downstream signal line 132 to the rear surface of the second mirror cabinet 22 using tape TP. This is a preparation for drawing these two wires from the third recess 22f to the upper surface 20a of the composite cabinet 20. FIG. The above work is done before shipment. The connection between the first mirror cabinet 21 and the second mirror cabinet 22 may be performed on site.

As shown in FIG. 7, the worker connects the connector 114 of the second power line 113 and the connector 115 of the connection line 116 in the composite cabinet 20 transported to the site. The connection between the connector 114 and the connector 115 may be made before shipment. As shown in FIG. 8, the operator pulls out the first power line 111, the first upstream signal line 121, and the first downstream signal line 131 from the second recess 21f to the upper surface 20a of the composite cabinet 20. and temporarily fixed with tape TP. Similarly, the operator pulls out the second upstream signal line 122 and the second downstream signal line 132 from the third recess 22f to the upper surface 20a of the composite cabinet 20 and temporarily fixes them. These five lines are temporarily fixed at least within a range corresponding to the lower surface opening 312 of the upper lighting fixture 30 . This is done by attaching these five lines from the top surface 20a of the composite cabinet 20 through the bottom opening 312 and the top opening 311 of the top lighting fixture 30 to the top lighting fixture 30 after attaching the top lighting fixture 30 to the top face 20a of the composite cabinet 20. This is preparation for pulling out the tool 30 to the outside. A range corresponding to the lower surface opening 312 may be indicated in advance on the upper surface 20a.

As shown in FIG. 9, the operator inserts the fixing member 39 (see FIG. 5) of the upper lighting fixture 30 into the pilot hole 29 (FIG. 2) fixed to the upper surfaces of the first and second mirror cabinets 21 and 22. fixed. Thereby, the upper lighting fixture 30 is attached to the upper surface 20 a of the composite cabinet 20 . The five wires temporarily fixed as described above are within the range of the lower surface opening 312 . Therefore, an operator can touch these wirings through the upper surface opening 311 . The operator peels off the tape TP attached to the upper surface 20a through the upper surface opening 311 and the lower surface opening 312 of the upper lighting fixture 30, and the upper power line 111, the first upstream signal line 121, and the first downstream signal line. 131, the second upstream signal line 122, and the second downstream signal line 132 are released.

An operator connects the upper power line 111, the first upstream signal line 121, the first downstream signal line 131, and the second upstream signal line 122 through the lower surface opening 312 and the upper surface opening 311 of the upper lighting device 30. , and the second downstream signal line 132 are pulled out of the upper lighting device 30 . The upper lighting fixture 30 incorporates an upper lighting wiring 141 that connects to the upper light emitting unit 41 . An operator pulls out the upper lighting wiring 141 to the outside of the upper lighting fixture 30 through the upper opening 311 .

The operator connects the upper power line 111 to the power connector 321 ( FIG. 6 ) of the upper control unit 32 . The operator connects the relay harness 160 to the signal connector 322 ( FIG. 6 ) of the upper control unit 32 . The operator connects the upper lighting wiring 141 to the first relay wiring 161 of the relay harness 160 . The operator connects the first downstream signal line 131 to the second relay wiring 162 . The operator connects the second downstream signal line 132 to the third relay wiring 163 . The operator connects the first upstream signal line 121 to the fourth relay wiring 164 . The operator connects the second upstream signal line 122 to the fifth relay wiring 165 .

Composite cabinets 20 may have different numbers of switches and lower lighting fixtures depending on the combination of single cabinets. A plurality of types of relay harnesses 160 having different numbers of connectors are prepared. The operator confirms the number of switches and lower lighting fixtures of the composite cabinet 20 at the site, selects the relay harness according to the number, and connects it to the signal connector 322 .

For example, when attaching the upper lighting fixture 30 to a composite cabinet in which two cabinets having a switch and no lower lighting fixture are installed side by side, instead of the relay harness 160, an operator uses a relay harness having three relay wires. It connects to the signal connector 322 . Therefore, even if the number of switches and lower lighting fixtures varies depending on the combination of single cabinets, the operator can easily change the configuration of the electric circuit of the lighting device 8 simply by exchanging the relay harness to be connected to the signal connector 322. can.

As shown in FIG. 10, an operator connects an upper power line 111, a first upstream signal line 121, a first downstream signal line 131, a second upstream signal line 122, a second downstream signal line 132, an upper The lighting wiring 141 and the relay harness 160 are pushed into the internal space R1. The operator inserts the upper control unit 32 from the upper opening 311 into the internal space R1. The operator fixes the first lid member 331 to the upper lighting fixture mounting body 31 using the fixing screws 36 .

The upper lighting fixture 30 is thin, and the internal space R1 is narrowed in the height direction Z. Therefore, depending on the position of the wiring, the first lid member 331 may be lifted from the upper lighting fixture mounting body 31 , and the operator may be prevented from fixing the first lid member 331 to the upper lighting fixture mounting body 31 . be. The dimension of the upper surface opening 311 in the depth direction Y is set wider than those of the upper control unit 32 and the first lid member 331 . The operator can fix the first lid member 331 to the upper lighting fixture mounting main body 31 while adjusting the position of the wiring by inserting a finger into the side of the upper control unit 32 .

The operator fixes the second lid member 332 to the upper lighting fixture mounting body 31 using the fixing screws 37 while the front end of the second lid member 332 is placed on the first lid member 331 . As a result, the top opening 311 of the top lighting fixture 30 is closed by the opening/closing lid 33 so that it does not open upward. The upper unit 10 assembled in this way is installed via the back panel 6 above the washbasin 2 installed on the floor.

In the lighting device 8, when the power plug 101 is inserted into an outlet, the first and second sensor switches 51b and 52b are activated. The first and second sensor switches 51b and 52b do not send a detection signal to the upper control unit 32 when they do not detect the user. The upper control unit 32 that has not received the detection signal does not supply power to the upper lighting fixture 30 via the first relay wiring 161 of the relay harness 160 and the upper lighting wiring 141 . An unpowered top light 30 is extinguished. The upper control unit 32 does not transmit a detection signal to the first lower control unit 51 d via the second relay line 162 of the relay harness 160 , the first downstream signal line 131 and the wiring 191 . The first lower control unit 51 d that has not received the detection signal does not supply power to the first lower light emitting unit 51 c through the first lower lighting wiring 151 . The first lower light emitting unit 51c to which power is not supplied is extinguished. Similarly, the upper control unit 32 does not send a detection signal to the second lower control unit 52d, and turns off the second lower light emitting unit 52d. Therefore, when the first sensor switch 51 and the second sensor switch 52b are in the OFF state, the upper lighting fixture 30, the first lower lighting fixture 55, and the second lower lighting fixture 56 are all turned off.

For example, when the user approaches the first faucet 51 a , the first sensor switch 51 b detects the user, is switched from the OFF state to the ON state, and transmits a detection signal to the upper control unit 32 . The detection signal is transmitted to the signal connector 322 of the upper control unit 32 via the wiring 181 , the first upstream signal line 121 and the fourth relay wiring 164 .

The upper control unit 32 transmits and receives detection signals via the signal connector 322 . Upon receiving the detection signal, the power supply circuit of the upper control unit 32 converts the commercial power supplied from the upper power line 111 to the power connector 321 to about several volts of direct current. The power supply circuit supplies converted electric power from the signal connector 322 to the upper light emitting unit 41 via the first relay wiring 161 and the upper lighting wiring 141 . The upper light emitting unit 41 is in a full lighting state in which all of the plurality of LEDs are lit, and emits light from the entire tops of the first and second mirror cabinets 21 and 22 .

Upon receiving the detection signal, the control circuit of the upper control unit 32 outputs the detection signal from the signal connector 322 to the second relay wiring 162 . The detection signal is transmitted from the second relay wiring 162 to the first lower lighting fixture 55 via the first downstream signal line 131 and the wiring 191 . The first lower control unit 51d converts the commercial power supplied from the first lower power line 112 to about several volts of direct current. The first lower lighting fixture 55 supplies the converted electric power to the first lower light emitting unit 51 c via the first lower lighting wiring 151 , triggered by the reception of the detection signal from the upper control unit 32 . The first lower light emitting unit 51 c lights up to illuminate the lower periphery of the first mirror cabinet 21 . Similarly, the second lower lighting fixture 56 is also lit.

Therefore, for example, when the first sensor switch 51b detects the user and is switched from the OFF state to the ON state, the lighting device 8 detects the entire upper lighting fixture 30, the first lower lighting fixture 55, and the second lower lighting fixture 56. It will be in a total lighting state in which The first sensor switch 51b continues to send detection signals to the upper control unit 32 while detecting the user. During that time, the illumination device 8 maintains the full lighting state. Similarly, the lighting device 8 is in the full lighting state when the second sensor switch 52b detects the user.

For example, when the user near the first faucet 51a moves away from the first faucet 51a, both the first sensor switch 51b and the second sensor switch 52b are turned off, and a detection signal is transmitted to the upper control unit 32. Gone. When the upper control unit 32 stops receiving the detection signal, the control circuit stops supplying power to the upper light emitting unit 41 . The upper light-emitting unit 41 is put into an all-light-off state in which all of the plurality of LEDs are turned off, and light is no longer emitted from the entire tops of the first and second mirror cabinets 21 and 22 .

When the upper control unit 32 stops receiving detection signals from the first sensor switch 51b and the second sensor switch 52b, it stops sending detection signals to the first and second lower lighting fixtures 55 and 56 . When the first lower control unit 51d of the first lower lighting fixture 55 stops receiving the detection signal from the upper control unit 32, it stops supplying power to the first lower light emitting unit 51c.
