  In FIG. 5, when a person wants to go up from the first floor to the second floor, when the sliding terminal of the three-way switch A is switched from the terminal 1 to the terminal 3, both ends of the lighting load L attached to the ceiling are electrically exchanged. Lights in series with the power supply AC. After the person goes up to the second floor, by switching the three-way switch B from the terminal 3 to the terminal 1, both ends of the lighting load L are electrically disconnected from the AC power source AC and turned off.

  In FIG. 6, for example, when the human sensor PED-A detects a human body, the control unit 25A generates a timer signal for a predetermined time and turns on the triac TRAC. As a result, a load current (lighting current) flows from the AC power source AC through the lighting load L attached to the ceiling through the triac TRAC-A and the current detection unit 30B. When the current detection unit 30B detects the load current, the current detection signal is sent to the control unit 25B while the current flows, and the control unit 25B of the automatic switch 10B turns on the triac TRAC-B during the current detection signal period. To. When the triac TRAC-B is turned on, a load current (lighting current) flows from the AC power supply AC to the lighting load L through the triac TRAC-B and the current detection unit 30A. This load current is detected by the current detection unit 30A, and the current detection signal is sent to the control unit 25A of the automatic switch 10A, so that the control unit 25A detects the triac TRAC-A as the detection output of the human sensor PED-A. At the same time, it is turned on by the current detection signal. This is the same when the human sensor PED-B on the automatic switch with human sensor 10B side detects a human body.

  Another lighting method is a method of partially illuminating the feet. For this purpose, at least three lighting fixtures for illuminating the feet dedicated to the stairs are preferably installed at the top and bottom of the stairs. Such lighting fixtures are partial lightings, whereas the former ceiling lights illuminate the entire staircase, so when one of the lighting fixtures that illuminate the feet installed above and below the staircase lights up, at least others I want the two lighting fixtures to light up in conjunction with each other. In the case of the former ceiling light, it lights up for a certain period of time and turns off forcibly when the time is over, but the time for going up and down the stairs varies depending on the person, so the lighting is on while the person stays on the stairs. It is desirable not to cut. This invention exists in provision of the interlocking type lighting fixture system which implement | achieves this request | requirement.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 shows a circuit diagram of an interlocking luminaire as a parent device according to an embodiment of the present invention.
In FIG. 1, the interlocking lighting apparatus 100 includes a power supply unit 101, a human body detection unit 102, an information transmission unit 103, an illuminance sensor unit 104, a control unit 105, and a lighting unit 106.

  Based on the measurement result of ambient illuminance by the illuminance sensor unit 104 and the human body detection result by the human sensor of the human body detection unit 102, the interlocking luminaire 100 has the control unit 105 lighting the illumination unit 106 all night, normal lighting or It can be controlled to be turned off.

  In order to generate DC power from AC100V, the power supply unit 101 uses lighting regulators LED1 to LED5 in a switching regulator circuit comprising a flyback switching transformer T1 and a switching element IC1 based on the full-wave rectified voltage of the diode bridge DB1. And a power source for a control circuit such as a human sensor +5 V from the transistor Q1 and the regulator IC3.

  The human body detection unit 102 uses a pyroelectric sensor as the human sensor PED1, amplifies the signal output by a two-stage amplifier circuit (IC4A, IC4B), and then outputs a human body detection output by the window comparator (IC5A, IC5B). Binarize. As shown in Fig. 2 (a), a pyroelectric sensor (hereinafter referred to as a human sensor) generates a single human body detection output as multiple pulse outputs. Therefore, the window comparator output of FIG. 2 (b) is transformed into the rectangular wave of FIG. 2 (e) by the transistors Q2, R19 and C13 and the Schmitt inverter IC6A, and the differential of C14 and R21 is obtained. It is converted into one pulse by the circuit and the Schmitt inverter of IC6B. This is further converted into a positive pulse in FIG. 2 (g) by an IC6C Schmitt inverter and output. In this way, one human body detection can be input as one pulse to the control microcomputer IC9.

  The information transmission unit 103 includes transistors Q3, Q4, and Q5 and a NOR gate IC8, and is a circuit for performing information transmission with a child unit to be described later or information transmission with another parent unit.

  The illumination unit 106 includes illumination LEDs 1 to LED5 and a lighting control unit thereof. The lighting control unit includes a switching transistor Q6 for brightness control by pulse width control. The lighting LEDs 1 to 5 are turned on at a duty of about 25% (hereinafter referred to as night lighting) when the predetermined ambient illuminance becomes 10 LX or less by the illuminance sensor PD1, and when the ambient illuminance exceeds about 30 LX as a night light. When the human body is further detected in this night-time lighting state, the duty is turned on at 100% (hereinafter, normal lighting), and the feet of the person going up and down the stairs can be brightly illuminated.

  FIG. 3 shows a circuit diagram of the slave unit 100-1 according to an embodiment of the present invention. Compared to the parent device 100 shown in FIG. Another feature of the slave unit 100-1 is that, unlike the master unit 100, the information transmission unit 103-1 has a simple configuration using a photocoupler IC2. In the slave unit 100-1, 101-1 is a power supply unit provided with a microcomputer power supply and LED illumination power supply, 105-1 is a control unit provided with a microcomputer IC9, 106-1 is illumination LEDs 1 to LED5 and lighting thereof. It is an illumination part containing a control part.

  The information transmission between the parent devices 100A and 100B and the child device 100-1 will be described with reference to FIG. FIG. 4 shows only the information transmission unit and its control unit (control microcomputer IC9) in the master unit and the slave unit.

  At this time, when the main body 100A side detects the human body and the illumination LED of the main body 100A is in the normal lighting state, the human body detection output is input to the pin 16 of the microcomputer IC9, and the pin 6 of the microcomputer IC9 is H. Level, turning on transistor Q3. As a result, the transistor Q4 becomes conductive and the power source Vcc is supplied to the SIG terminal. At this time, since the input terminal 1 of the NOR gate IC8 is at the H level, the NOR output terminal 4 is always at the L level. The microcomputer IC9 determines that the NOR output terminal 4 has not changed. Since Vcc is supplied from the master unit 100A to the SIG terminal of the slave unit 100-1, the primary side of the photocoupler IC2 of the slave unit 100-1 is turned on and the transistor on the output side is also turned on. When the pin 5 of the microcomputer IC9 of -1 changes from the H level to the L level, the information of the parent device 100A is transmitted to the child device 100-1. As a result, the LED for illumination on the side of the handset 100-1 is normally turned on. On the other hand, the Vcc of the parent device 100A is also supplied to the SIG terminal of the parent device 100B, the transistor Q5 is turned on, and the input terminal 2 of the NOR gate IC8 of the parent device 100B becomes L level. At this time, since there is no human body detection in the parent device 100B, the level of the pin 6 of the microcomputer IC9 remains L, so the output terminal 4 of the NOR gate IC8 changes from L level to H level. From this, the information of the parent device 100A is also transmitted to the parent device 100B. As a result, the illumination LED on the parent device 100B side is also normally lit.

  Next, when a person passes through the parent device 100A and reaches the parent device 100B, a human body detection signal of the parent device 100B is generated. At this point, the lighting of the staircase lamp is returned to the original night-time lighting. When a human body detection transmission signal is generated from the parent device 100B as in the case where the human body is detected by the parent device 100A as described above, the information is similarly transmitted from the parent device 100B to the child device 100-1 and the parent device 100A. The In this case, it is necessary to change the signal content (kind) to the lighting signal from the parent device 100A because it is necessary to turn off the signal from the parent device 100B. As an embodiment for transmitting (realizing) information on the difference in signal content (type), there is a method of changing the pulse width or the number of pulses using a pulse signal. By changing the pulse width or the number of pulses, information to be transmitted can be used not only for turning on / off the LED during normal lighting, but also for information on the lighting / extinguishing state at night lighting, for example.

  That is, since the environments in which the parent device 100A and the parent device 100B are installed are different, a difference occurs in the ambient illuminance. For example, the first floor of the staircase is darker than the second floor, and when the brightness is detected by the illuminance sensor on the first floor, there is a case where the night lighting on the first floor is lit earlier than that of the second floor. In this case, the information on the already-lit nightlight can be sent from the first floor parent device to the second floor parent device by changing the pulse width or number of pulses different from that during normal lighting. When the main unit on the first floor lights up at night based on the detection result of the illuminance sensor, if the status of the night-time lighting is transmitted to the main unit on the second floor, the main unit on the second floor normally lights up by detecting its own human sensor Set to standby (preparation) state. Then, when a person comes to the main unit on the second floor, the human body is detected, and the main unit on the second floor is normally turned on to brighten the vicinity of the stairs. On the other hand, information that is turned off at night can also be transmitted.

  In this way, two lighting fixtures that detect infrared rays radiated from the human body and turn on LED lighting are connected as a parent device, and the LED lighting device is interlocked while the parent device is lit during that time. The interlocking type LED lighting fixture which connects a device is realizable.

  According to an embodiment of the present invention, a parent-child interlocking type stair light using a human sensor and a surrounding illuminance detection illuminance sensor is installed at each of the stair lifts, and one or more slave units are installed in the middle of the stairs. And since the signal transmission between the parent and child unit is realized by changing the pulse width or the number of pals by connecting the parent and child with two signal lines, people can send various information, It is possible to continue to illuminate the midfoot while going up and down the stairs, that is, while the person is climbing up or down the stairs. Moreover, since it also functions as a nightlight, it is possible to guide to the stairs and provide a gentle staircase light. In addition, the interlocking type lighting fixture system and the interlocking type lighting fixture according to the present invention are useful not only for stair lights but also for passage lights such as corridors.

  Although the embodiments of the present invention have been described, these embodiments are presented as examples, and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention.
