When the brightness is turned on and the high illuminance signal is received, a turn-off command signal is given to the drive circuit 40 to turn off the stair light.

When the control circuit 37 receives the human body detection signal from the level determination circuit 33 (a) while receiving the low illuminance signal, it sends a high brightness lighting command signal to the open drive circuit 40 for a certain period of time Tll. , (b) Identification code setting device 34

It has a circuit 38' and performs a receiving operation but not a transmitting operation.

The control unit R2 controls the lighting of the stair light 17, the human body detection sensor 31 has a detection range B2 near the entrance 15A of the stairs 15, and the illumination sensor 35 monitors the illuminance of the illumination area of the stair light 17. .

Further, the identification code setter 34 sets C0DE-3.

The drive circuit 40 includes, for example, as shown in FIG. 4, a triac 43 that controls the phase of the voltage of an alternating current power source AC, and a photocoupler 4 that provides a gate signal to the triac 43.
2. It has a zero cross detector 41 that detects the timing when the voltage of the AC power source AC passes the zero point.

Next, the operation of the apparatus of this embodiment will be explained.

It is assumed that a person M climbs the stairs from the first floor IF to the third floor 3F.

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 sensor 35 of each control unit R1 to R3 is at a high level, and the output of the level determination circuit 36 is at an L level. , the control circuit 37 generates neither a low-intensity lighting command signal nor a high-intensity lighting command signal, and the stair lights 16 to 18 are turned off.

When the illuminance of the illumination area falls below the set illuminance after sunset, the level determination circuit 36 generates a low illuminance signal, so the control circuit 37 synchronizes the low brightness lighting command signal with the output of the zero cross detector 41. The photocoupler 42 of the drive circuit 40
Send to.

This causes the triac 43 to reach the firing phase α.

(for example, electrical angle 150”) ONL, stair light 16-1
8 lights up at low brightness.

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

(a) When the person M comes to the top entrance 14A of the stairs 14, the human body detection sensor 31 of the control unit R1 detects the person M.
The control unit R1 level determination circuit 36 generates a human body detection signal and inputs it to the control circuit 37.

At this time, since the stair light 14 is in a low brightness lighting state, the control circuit 37 of the control unit R1 sends a high brightness lighting command signal to the drive circuit 4.
Give to 0.

At the same time, the transmitting/receiving section 38 wirelessly transmits the signal S3 having the identification code C0DE3 through the antenna 39.

Since this signal S3 has the identification code C0DE-3,
The control unit R2 decodes and receives the signal, and since the stair light 17 is in a low-intensity lighting state, the control circuit 37 of the control unit R2 sends a high-intensity lighting command signal to the drive unit 40 of the control unit R2. .

The 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. At the same time, a timer section (not shown) of the control circuit 37 (set time Tl1) starts measuring time.

This causes the triac 43 to reach the firing phase α.

(For example, ONL at electrical angle 30°〈α,), stair light 16
And the stair light 17 lights up with brightness.

As a result, the outputs of the illuminance sensors 35 of the control units R1 and R2 change to H level, but the control circuit 37 does not receive the high brightness lighting command signal until the set time T8 has elapsed and the timer unit counts up. The output continues, and the stair lights 16 and 17 maintain a high brightness lighting state.

As a result, the stairway space of the stairs 14 is sufficiently illuminated, and the person M can safely climb the stairs 14 toward the 2nd floor 2F.

Note that when the set time Tll has elapsed, the control circuit 37 stops sending out the high-intensity lighting command signal.

As a result, the illuminance of the illumination area of the stair lamp 16.17 falls below the set illuminance, so the control circuit 37 sends a low brightness lighting command signal to the drive circuit 40, and the stair lamp 16.17 Switches to low brightness lighting.

This set time T is set to a time sufficient for the person M to completely ascend and descend the stairs 14.15.

(b) When the person M enters the upper half of the stairs 14, the human body detection sensor 21 of the monitoring unit T1 detects the person M, so the level determination circuit 23 generates a human body detection signal, and the monitoring unit T1 detects the During the time Δt, a signal S1 with an identification code C0DE-1 is sent out.

(c) Since this signal S1 has the identification code C0DE-1, the control unit R1 determines that the signal is addressed to itself.

The control circuit 37 of the control unit R1 resets the timer unit and restarts the time T even though the stair light 16 is in a high-intensity lighting state.
The high-intensity lighting command signal is continued to be sent to the drive circuit 40 for a time Tll from this timing.

(d) When the person M stands at the top 15A of the stairs 15, the human body detection unit of the receiving section R2 generates a human body detection signal and inputs it to the control circuit 37.

At this time, the stair light 17 is lit with high brightness, but the control circuit 37 resets the timer unit (not shown) and starts counting a new time T8.
The high-intensity lighting command signal continues to be sent until the time elapses.

(e) When further climbing to the 3rd floor, 3F, when the person M advances to the lower half of the stairs 15, the human body detection sensor 21 of the monitoring unit T2 detects the person M, and the level determination circuit 23 generates a human body detection signal. Then, the monitoring unit T2 sends out a radio signal S2 having an identification code C0DE-2.

(f) Since this wireless signal S2 has the identification code C0DE2, the control circuit 37 of the control unit R3 determines that the signal is addressed to itself.

Since the stair light 18 is in a low brightness lighting state, the control circuit 37 of the control unit R3 sends a high brightness lighting command signal to the drive circuit 40 to turn on the stair light 18 at high brightness.

The above is an explanation when a person goes up the stairs, but the same applies when a person goes down the stairs.
When person B stands, the stair light 18.17 lights up at a high intensity, and when this person M comes to the lower half of the stairs 15, the high intensity lighting state of the stair light 18, which is in the high intensity lighting state, is extended for a certain period of time T8. When the stair lamp 16 reaches the upper half of the stairs 14, the stair light 16, which has been in a low-intensity lighting state, changes to a high-intensity lighting state.

In this way, in this embodiment, the first floor 11 or 3
When a person M stands at the top or bottom of the stairs on floor 130, the stair light 16 or 18 on that floor and the stair light 17 on the 2nd floor 2F toward which the person is heading are switched from low-intensity lighting to high-intensity lighting.

Furthermore, when descending from the second floor 12 to the first floor, when proceeding to the upper half of the stairs 14, the monitoring unit T1 sends a signal S1 to the control unit R1, causing the stair light 16 to turn on with high brightness. When climbing to the third floor 13, when proceeding to the lower half of the stairs 15, the monitoring section T2 transmits a signal S2 to the control section R3, and the stair light 18 is turned on with high brightness.

Therefore, in this embodiment, the stair lights on the floors that the person M is about to climb or descend will automatically turn on at high brightness before the person M reaches these floors, and the stair lights on the floors that the person M is about to climb or descend will automatically turn on at high brightness, like guide lights. Since the staircase space where the person M is going to climb or descend is illuminated, the person M can safely ascend or descend to the next floor.

When a person M enters the human body detection range, the monitoring unit T1 located in the middle of the stairs 14 transmits a signal S1 and lights up with high brightness even if the person M is heading from the first floor 11 to the second floor 12. Since the high-intensity lighting time of the stair light 16 on the first floor 11 is extended, the person M who has climbed to the upper half of the stairs 14
Even when returning to No. 1, the stair light 16 will not go out on the way back.

Similarly, person M who descended from the third floor 13 to the lower half of the stairs 15
Even when the person returns to the third floor 13, the stair light 18 does not go out during the return.

Further, for example, while the control circuit 37 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 entrance 14A and the control unit R1 detects the human body. When the signal is generated, the timer section of the control circuit 37 is reset and starts counting again, and the stair light 16 that is lit at high brightness continues to be lit at high brightness for a further set time TI. , even if someone else starts going down the stairs while person M is halfway down the stairs 14, the stair light 16 will turn off before the person who started going down later finishes going down the stairs 14.
The light never goes out.

In addition, in this example, when the illuminance of the stairway space becomes low,
The stair light turns on at low brightness and acts as a backup light, and when someone stands at the entrance to the top or bottom of the stairs in this state, the stair light turns on at high brightness and there is no need to operate a switch, so it is safe and smooth. I can go up and down stairs.

In the above embodiment, the lighting is switched to high brightness on condition that the illuminance of each illumination area of the stair lights 16, 17, and 18 is low, that is, the stair lights are lit at low brightness. Without considering the illuminance of the area, the control units R1 to R3 control the staircase light 16 due to a person entering the human body detection area that they are each responsible for.
~18 is turned on, and the controllers R1 and R3 output signals S3 and S4.
It may also be configured to wirelessly transmit.

Furthermore, since the stairway light is automatically turned off after a certain period of time Tll has elapsed after being turned on, there is no need to forget to turn it off, and wasteful power consumption can be avoided.

In addition, monitoring units T1 and T2 and control units R1 and R3 control unit R1
, R3 and the control unit R2 communicate with each other by wireless signals, so there is no need for wiring, and the workability of the device is improved.

Note that the wireless signals (radio waves, infrared rays, etc.) sent by the monitoring units T1 and T2 and the control units R1 and R3 are made into a combination of logical signals of a certain length when there is a possibility of interference with other signals.

Further, the present invention is not limited to the control of stair lights in a three-story building, and similar effects can be obtained even when applied to stair lights in a four-story building.

(Effects of the Invention) As explained above, in the present invention, when going from the second floor to the next floor, when a person goes halfway up the stairs between the second floor and the next floor, the stair light for the next floor is turned on. Since stair lights on floors that are not intended for this purpose are not lit, it is possible to prevent the stair lights from being turned on unnecessarily.Furthermore, when the illuminance of the lighting area becomes low due to sunset, etc., the stair lights will be turned on. The brightness lights up and serves as a backup light.In this state, if someone comes to the top or bottom of the stairs, the stair light will turn on with high brightness, and when the person comes halfway down the stairs from the second floor, it will light up the stairs to the next floor. The stairway lights turn on at high brightness, and these high-intensity lighting conditions continue until the person finishes passing through the lighting area, which is more economical than conventional methods.
Even if the illumination area is a stair space with curved stairs, lighting control according to the movement of people can be achieved completely switchlessly by using one stair light for each floor.
