The operation of sending data to the circuit 40 is performed.

The drive circuit 40 lights the stairway light at high brightness while receiving the high brightness lighting command, and when the high brightness lighting command disappears,
Turn on the stairway lights at low brightness.

The control unit R1 controls the lighting of the stair light 16, the human body detection circuit 31 has a detection range E1 near the gold eye 14A of the stairs 14, and the illuminance detection circuit 32 monitors the illuminance of the illumination area of the first stair light 16. . In addition, the identification code setting device 34 is C0DE-A
Set. The control unit R2 controls the lighting of the stair light 17, its human body detection circuit 31 has a detection range E2 near the metal eye 15A of the stairway 15, and the illuminance detection circuit 32 monitors the illuminance of the illumination area of the stair light 17. . Further, the identification code setter 34 sets C0DE-B and C0DE-C. The control unit R3 controls the lighting of the stairway light 18, and the human body detection circuit 3
1 has a detection range E3 near the exit 15B of the stairs 15,
The illuminance detection circuit 32 monitors the illuminance of the illumination area of the stairway light 18. Further, the identification code setter 34 sets C0DE-D.

Note that the drive circuit 40, for example, as shown in FIG.
a triac 43 that controls the phase of the voltage of the alternating current power supply AC;
It has a photocoupler 42 that provides a gate signal to the triac 43, and a zero cross detector 41 that detects the timing of the voltage zero point passage of the alternating current power source AC.

Next, the operation of the apparatus of this embodiment will be explained with reference to the waveform time chart of FIG. 6 and the operation flow chart of FIG. 7.

Assume that a person climbs the stairs from the 1st floor, 1st floor, to the 2nd floor, 2nd floor.

When the illuminance of the illumination area of each stairway light 16 to 18 is sufficient, such as during the daytime, the output of the illuminance detection circuit 32 of each control unit R1 to R3 is at L level, and the control circuit 33 turns on the low brightness. No command signal or high-intensity lighting command signal is generated, and stair light 1
6-18 are off. When the illuminance of the illumination area falls below the set illuminance after sunset, the illuminance detection circuit 32 generates a low illuminance signal, so the control circuit 33 synchronizes the low brightness lighting command signal with the output of the zero cross detector 41. and sends it to the photocoupler 42 of the drive circuit 40. As a result, the triac 43 has a firing phase αd (for example, an electrical angle of 1500
), the ONL and stair lights 16 to 18 are lit at low brightness.

Assume that it is now nighttime and the stair lights 16, 17 and 18 are in the low-intensity lighting state.

(a) When a person comes to 14A of the stairs 14, the control unit R
A human body detection circuit 31 detects a person and inputs a human body detection signal to a control circuit 33. At this time, since the stair light 16 is in a low-intensity lighting state, the control circuit 33 of the control unit R1 provides a high-intensity lighting command signal to the drive circuit 40. This high-intensity lighting command signal is sent to the photocoupler 42 of the drive circuit 40 in synchronization with the output of the zero-cross detector 41, and at the same time, the timer section of the control circuit 33 starts timing. As a result, the triac 43 has a firing phase αu (for example, an electrical angle of 3
It turns on at 0°〈α,), and the stair light 16 lights up with high brightness.

As a result, the output of the illuminance detection circuit 32 changes to H level, but the control circuit 33 continues to send out the high-intensity lighting command signal until the set time TO has elapsed and the timer section counts up. The stair light 16 maintains a high brightness lighting state.

As a result, the illumination area of the stairs 14 is sufficiently illuminated, and a person can safely start climbing the stairs 14 toward the landing 14c.

Note that when the set time To has elapsed, the control circuit 33 stops sending out the high-brightness lighting command signal.

As a result, the illuminance of the illumination area of the stair lamp 16 decreases below the set illuminance, so the control circuit 33 sends a low brightness lighting command signal to the drive circuit 40, and
will switch to low brightness lighting.

This set time To is set to the time required for a person to sufficiently pass the landing from the top or exit of the stairs 14 and 15.

(b) When a person starts climbing the stairs 14 and enters the human body detection range A, the human body detection circuit 2LA of the monitoring unit T1 generates a human body detection signal, the timer circuit 25A of the monitoring unit T1 triggers the oscillation circuit 25A, The oscillation circuit 25A has a minute time Δt
During this period, a signal S1 having an identification code C0DEA is sent out.

(C) This signal S1 is sent to the receiving circuit 35 of the control unit R1=R3.
However, since it has the identification code C0DE-A, the control circuit 33 of the control unit R1 determines that the signal is addressed to itself (addressed to its own station). Since the stair light 16 is in the high-intensity lighting state, the control circuit 33 of the control unit R1 resets the timer unit and starts counting again, and outputs a high-intensity lighting command signal until the time To elapses from this timing. The drive circuit 40
Send to.

(d) When a person passes the landing 14C and starts climbing the upper half of the stairs 14 and enters the human body detection range B, the human body detection circuit 21B of the monitoring section T1 generates a human body detection signal, so that the human body detection circuit 21B of the monitoring section T1 generates a human body detection signal. The timer circuit 25B triggers the oscillation circuit 25B, and the oscillation circuit 25B oscillates the signal S2 having the identification code C0DE-B for a minute time Δt and transmits it via the antenna 27. Since the identification code of this signal S2 matches the identification code C0DE-B set in the control unit R2, the control circuit 33 of the control unit R2 determines that the signal is addressed to itself, and the stair light 17 turns on at low brightness. Since it is in the state, a high brightness lighting command signal is sent to the drive circuit 40. The drive circuit 40 of the control unit R2 operates as described above to turn on the stair light 17 at high brightness.

(e) When a person climbs the stairs 14 and stands on the metal eye 15A, the human body detection circuit 31 of the control section R2 generates a human body detection signal and inputs it to the control circuit 33. At this time, stair light 1
7 is lit with high brightness, but the control circuit 33 resets the timer section and starts counting a new time To, and from this timing until the time To has elapsed, the control circuit 33 stops sending out the high brightness lighting command signal. continue.

(f) When the person continues to climb the stairs 15, the person enters the human body detection range C, so the monitoring subordinate 20 human body detection circuit 2'IC
generates a human body detection signal, and the monitoring unit 1-2 receives the identification code C.
A signal S3 having 0DE-C is sent out.

(Since this cloudy signal S3 has the identification code C0DE-C, the control circuit 33 of the control unit R2 determines that the signal is addressed to itself. Therefore, the timer section is reset to start counting again, and a high-intensity lighting command signal is sent to the drive circuit 40 until the time To has elapsed from this timing.

(h) When a person passes the landing 15C and starts climbing the upper half of the stairs 15 and enters the human body detection range, the human body detection circuit 21D of the monitoring section T2 generates a human body detection signal, so the human body detection circuit 21D of the monitoring section T2 generates a human body detection signal. transmits a signal S4 with identification code C0DE-D via antenna 27. The identification code of this signal S4 is the identification code C0DE set in the control unit R3.
-D, the control circuit 33 of the control unit R3 determines that the signal is addressed to itself, and since the stair light 18 is in a low-intensity lighting state, it sends a high-intensity lighting command signal to the drive circuit 40. . The drive circuit 40 of the control unit R3 operates as described above to turn on the stair light 18 at high brightness.

The above is an explanation when a person descends the stairs, but the same applies when a person descends the stairs. When the person M stands at the exit 15B of the stairs 15, the stair light 18 lights up with high brightness, and this When a person descends to the lower half of the stairs 15 (human body detection range C), the stair light 17, which is in a low-intensity lighting state, turns on in a high-intensity state, and the stairs 1
When the stair light 16 passes the landing 14C at No. 4 and enters the human body detection range A, the stair light 16, which is in the low-intensity lighting state, shifts to high-intensity lighting.

As described above, in this embodiment, when a person M stands at the stairwell entrance or stairway exit of each floor at night, etc., the control units R1 to R switch the stairway lights of the stairs from low-intensity lighting to high-intensity lighting.
3, so you can safely start climbing or descending the stairs.

Furthermore, the stairway space of the stairs 14 is divided into two human body detection ranges A and B.
When a person enters the human body detection range A, a signal S is sent to the control unit R1.
1, when a person enters the human body detection range B, the monitoring unit T1 sends a signal S2 to the control unit R2 wirelessly, and the stairs 15
The stairway space is divided into a second-floor half and a third-floor half by two human body detection ranges C and D, and when a person enters the human body detection range C, a signal is sent to the control unit R2. We installed a monitoring unit T2 that sends a signal S4 to the control unit R3 wirelessly when a person enters the human body detection range of S3. The stair light on the floor you are aiming for changes from low brightness to high brightness, and the stair light on this floor does not turn on high brightness until you get close to the floor you are aiming for, so people can safely climb up and down to the next floor. can.

Further, for example, while the control circuit 33 of the control unit R1 sends out a high-intensity lighting command signal and the stair light 16 is lit at high intensity, another person comes to the stairway exit 14A and the human body of the control unit R1 is turned on. When the detection circuit 31 generates a human body detection signal, the timer section of the control circuit 33 is reset and starts counting again, and the stair light 16 that is lit at high brightness is further turned on at high brightness for the set time To. Since the light will continue to be lit, even if someone else starts going down the stairs while a person is halfway down the stairs 16, the stair light 16 will be turned off before the person who started going down later has finished descending the stairs 14. There is no such thing as the light going out.

Also, for example, when a person passes the starting point 14A of the stairs 14 and enters the human body detection range A, the high-intensity lighting time of the stair light 16 that is lit at high intensity is extended, so that the person climbs up to near the landing 14C and then Even when the person returns to the first floor 11, the stair light 16 continues to be lit at high intensity until the person descends to the first floor 11.

In addition, in this embodiment, when the illuminance of the stair space becomes low, the stair light turns on at a low intensity and serves as a backup light, and in this state, when a person stands at the stairwell entrance or stairway exit, The lights turn on with high brightness and there is no need to operate a switch, so you can go up and down the stairs safely and smoothly.

In addition, when a certain period of time To elapses after the stair light is turned on,
It automatically switches to low brightness, so you don't have to forget to turn it off.
Wasteful power consumption can be avoided.

Further, since the monitoring units TI and T2 communicate with the control units R1 to R3 by wireless signals, no wiring is required, and the workability of the device is improved.

Further, in the above embodiment, the illuminance of each illumination area of the stair lights 16 to 18 is low, that is, the stair lights 16 to 18 are switched to high brightness lighting on the condition that they are lit at low brightness. Without considering the illuminance of the above-mentioned illumination area, the control units R1 to R3
The stairway lights 16 to 18 that each person is responsible for may be simply turned on when a person enters the human body detection range E1 to E3 that each person is responsible for and receives a wireless signal addressed to the person.

Furthermore, the present invention is not limited to three-story houses;
A similar effect can be obtained by applying the present invention to stair lights in houses of four or more stories, and the stairway to which it is applied is not limited to curved stairs.

(21) (22) In addition, the wireless signals (radio waves, infrared rays, etc.) sent by the monitoring units T1 and T2 are converted into a combination of logical signals of a certain length when there is a risk of interference with other signals. do.

[Effects of the Invention] As explained above, when a person comes to the stairway entrance or exit, the stairway light on that floor is automatically turned on at high brightness, and when the person passes halfway down the stairs, the person is directed to the floor they are heading for. Since the stairway lights automatically turn on at high brightness, it is possible to prevent unnecessary lighting of the stairway lights.In addition, when entering the stairs through the stairwell entrance or exit, the high brightness light in front of The lighting time of the lit stairway lights is extended, so even if a person turns back halfway, the stairway lights will not go out while they are going back.Furthermore, it will prevent the stairway lights from turning off when the sun goes down, etc. When the illuminance becomes low, the stairway lights turn on at low brightness and serve as a backup light.In this state, if someone comes to the stairwell entrance or stairway exit, the stairway lights turn on at high brightness and the person When the person passes the middle of the stairs, the stairway lights on the floor they are about to head on turn on at high brightness, and these high brightness lighting conditions continue until the person finishes passing through the above-mentioned lighting area (23). ,
It is economical and even if the lighting area is a curved staircase, one
Using two stair lights, it is possible to control lighting according to the movement of people without using a switch.
