Japanese Patent No. 4134125 Japanese Patent No. 3596309

As a method for illuminating a corridor, a staircase, etc., a three-way connection in which one luminaire is attached to the ceiling as shown in FIG. 17 and is controlled by two switches is well known.
In FIG. 17, 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.

FIG. 18 shows a three-way connection of the automatic switch disclosed in Patent Document 1 described above, which automatically controls a lighting fixture attached to the ceiling by detecting infrared rays radiated from the human body.
In FIG. 18, for example, when the human body detection sensor (synonymous with 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 body detection sensor PED-A. At the same time, it is turned on by the current detection signal. This is the same when the human body detection sensor (synonymous with the human sensor) PED-B on the automatic switch 10B side with the human body detection sensor detects the human body.

  As another illumination method, there is a method of illuminating the wall surface of the corridor, and it is desirable to install a plurality of lighting fixtures for illuminating the wall surface dedicated to the passage in the passage such as the corridor. Such a luminaire is a partial illumination while the former ceiling light illuminates the entire passage, so when one of the luminaires illuminating the wall installed on the entrance side of the passage is lit, I want all the lighting fixtures to light up simultaneously in conjunction. In the case of the former ceiling light, it lights up only for a certain period of time and turns off forcibly when the time is over, but the time for going to and from the corridor differs depending on the person, so the lighting is turned off while the person stays in the hallway. Desirably not.

In view of the above-described problems, the present invention makes it possible to set and automate an appropriate lighting environment for a user using a human sensor and an illuminance sensor for detecting ambient illuminance. safely it can be traffic, and to provide an interlocking type lighting fixtures can be illuminated by necessary time.

In order to realize the above requirements, the present invention provides a lighting apparatus as two master units arranged at both ends of the passage and a slave unit arranged at an intermediate position between the two master units at both ends of the passage. in conjunction with lighting fixtures, it can be turned all the luminaires simultaneously, yet while the person remains in the corridor is to provide an interlocking type lighting fixtures that can be all the luminaires lit continuously.

An interlocking lighting fixture according to one aspect of the present invention includes two lighting fixtures, and can be turned on or off in conjunction with each other in an illumination area including a passage between the lighting fixtures. luminaire, a human sensor which detects the human body, an illuminance sensor for detecting the illuminance around a lighting unit turned on or off using the illuminance sensor and the motion sensor is controlled, between the luminaire conjunction with to simultaneous lighting or simultaneous off, signaling to transmit between the luminaire and the lighting state or off state of the lighting unit based on human signal from the motion sensor to generate a table to information And when a person passes through an illumination area including a passage between the luminaires from one luminaire side to the other luminaire side, the human body is first detected by a human sensor of the one luminaire. When detected, based on the detection signal The lighting unit of the one lighting fixture is turned on, the lighting result is transmitted to the other lighting fixture via the information transmission unit of each lighting fixture, and the lighting unit of the other lighting fixture is turned on. Maintains the lighting state, and then when the human sensor of the other lighting fixture detects the human body, the lighting unit of the other lighting fixture is turned off based on the detection signal, and the result of the turn-off is the result of each lighting fixture. Is transmitted to the one lighting fixture via the information transmission portion, and the lighting portion of the one lighting fixture is turned off .

A constant voltage diode ZD4 connected in parallel at both ends is provided. The minus terminal of the full-wave rectifier diode bridge DB2 functions as a reference potential point (GND) on the secondary side (DC output side) of the full-wave rectifier diode bridge DB2.

  The second power supply circuit of the two power supply circuits is a power supply circuit that generates a DC voltage to be supplied to the illuminance sensor unit 12, and includes a resistor R19, between the AC input terminal L and the AC input terminal N. A half-wave rectifier circuit is formed by R22 and diodes D7 and D8.

By connecting a resistor R24 in parallel, the voltage at the negative terminal of the comparator IC5 is lowered when the illumination unit 13 is turned on, and an illuminance difference is obtained between the ambient environment illuminance required at the time of lighting and the ambient environment illuminance required at the time of turning off. The resulting hysteresis function is provided to the comparator IC5. Since the illumination unit l3 including the LED group for foot illumination is turned on / off due to the ambient environment illuminance, it is not affected by the interlocking function described later.

The power supply unit 21 includes two power supply circuits, a first power supply circuit and a second power supply circuit.

  The first power supply circuit of the two power supply circuits (power supply unit 21) is a power supply circuit that generates a rectified voltage to be supplied to the illumination unit 22 including the LED group for main illumination, and is connected to the AC input terminal L and the alternating current. Between the input terminal 2, a parallel circuit of a resistor R2 and a capacitor C2, a resistor R1, and a full-wave rectifier diode bridge DB1 that is a full-wave rectifier circuit are connected in series.

A constant voltage diode ZD2 connected in parallel at both ends is provided. The minus terminal of the full-wave rectifier diode bridge DB1 functions as a reference potential point (GND) on the secondary side (DC output side) of the full-wave rectifier diode bridge DB1.

Of the two power supply circuits (power supply unit 21), the second power supply circuit has a half-wave rectifier circuit between the AC input terminal L and the AC input terminal 2 by resistors R3 and R4 and diodes D1 and D2. A parallel circuit of a charging capacitor C3 and a constant voltage diode ZD1 is connected to the rectified output terminal, and the constant voltage output is supplied to the regulator IC1 as a DC power supply voltage for the regulator and connected in parallel to the output side of the regulator IC1. It is output as a stabilized DC power supply voltage through the smoothing capacitor C4, and supplies power to the current detection unit 23, the control unit 24, the human sensor unit 25, and the PD touch illuminance sensor unit 26.

  A current detector 23 is connected between the AC input terminal 2 and the current detection terminal 3. The current detection unit 23 detects a difference between the current consumption when the lighting unit is turned off and the current consumption when the lighting unit is turned on, and transmits the detection information between the lighting fixtures using the power line. Increase / decrease of the current value of one AC100V line is used as a transmission signal. In other words, the lighting fixture body is a three-wire system with three AC100V lines.

  In the current detection unit 23, three diodes D4 to D6 are connected in series in the forward direction between the AC input terminal 2 and the current detection terminal 3, and the diode D3 is parallel to the diodes D4 to D6 in the reverse direction. Further, a shunt resistor R34 is connected between the current detection terminal 2 and the current detection terminal 3, while a light emitting diode which is a primary side light emitting element of the transistor output type photocoupler PC1 is connected in parallel. Has been. The photocoupler PC1 is constituted by a pair of a primary side light emitting diode and a secondary side phototransistor.

  The control unit 24 is connected to the phototransistor on the secondary side of the photocoupler PC1, and is a current detection unit (capacitor C11, resistor R27, resistor R38, and MOS transistor Q2) based on lighting of the LED groups 1 to 6, and its current detection. Microcomputer IC2 that receives detection signals including signals and controls the illumination unit 22 based on the detection results, and lighting modes (forced lighting, forced extinction, automatic by human feeling (interlocking with the interlocking part B) each mode) A change-over switch SW1 and a change-over switch SW2 for changing the brightness (high / low) of the ambient environment illuminance (threshold) necessary for lighting when the human sensor PED1 detects a person are provided.

The source is connected to the reference potential point, and the drain is connected to the DC stabilizing voltage line VD (that is, the collector output terminal of the phototransistor) via the resistor R38. When the phototransistor on the secondary side of the photocoupler PC1 becomes conductive, the capacitor C1 connected to the emitter side of the photocoupler PC1 is charged, the potential at both ends of the load resistor R2 7 rises to almost the power supply voltage, and the MOS transistor Q2 is turned on. At this time, the drain potential of Q2 drops from the H level to the L level, so that the control microcomputer IC2 can detect that a current flows through the three diodes D4 to D6. At this time, when the microcomputer IC2 sets the gate potential of the switching element Q1 of the LED group of the illumination unit 22 to L level, the drain becomes H level and the gate potential of PM1 becomes H level and turns on. A current flows through the LED group for illumination, and the illumination is turned on.

  The human sensor unit 25 includes a human sensor PED1 called a pyroelectric sensor in which a condensing lens is arranged in front, and an amplifying unit that amplifies the sensor output several thousand times.

  The human sensor PED1 can detect infrared rays, which are heat rays radiated from the human body, and output them as a weak voltage. The human sensor PED1 has first to third terminals, the output voltage VD of the regulator IC1 is supplied to the first terminal via the resistor R6, and the reference potential is supplied to the third terminal. A point GND line is connected, and a weak detection voltage corresponding to this is output as a sensor output from the second terminal when infrared rays are detected. The sensor output is amplified by a first stage amplification unit comprising an operational amplifier IC3A, capacitors C8 and C6, resistors R9 and R10 via an input circuit comprising a resistor R7, a resistor R8 and a capacitor C5, and further, a resistor R11, a capacitor C7 and an operational amplifier IC3B. , A capacitor C9, a resistor R12, and a voltage dividing resistor R13, R14 are amplified by a second stage amplifying unit to be amplified several thousand times and input to the A / D terminal of the microcomputer IC2 as a human signal.

  As described above, the PD touch illuminance sensor unit 26 can take in the surrounding environment (external light) from the daylighting unit (external light intake port) provided in the casing (exterior body) of the lighting fixture. The illumination sensor PD1 detects this by closing the daylighting part with a finger for a short time (for example, 2 seconds) and transmits this to the microcomputer IC2 for control, and the microcomputer IC2 determines the dimming command from the change characteristic of the detected illuminance at that time. Thus, the dimming command signal can be output.

The operation of the interlocking unit will be described below.
The power supply unit 21 of the interlocking unit 20A has the same configuration as the power supply unit 11 of the independent unit 10A. The AC input terminals L and N will be described. In FIG. 1, there is a jumper line JP1 at the AC input terminal L and a jumper line JP2 between the AC input terminals L and N. This is an alternative, and when the jumper line JP1 is used, the jumper line JP2 is do not use. The reverse is also true. The interlocking luminaire requires two master units, the first master unit is configured to include a main light source interlocking unit 20A and a sub-light source independent unit 10A, and the second master unit is a main light source interlocking unit 20B. However, in the following description of the operation, the operation of the interlocking unit 20A and the interlocking unit 20B that operate in conjunction with each other will be described. This will be described in detail with reference to FIG.

  FIG. 2 shows an equivalent circuit diagram of a schematic configuration in which the two interlocking portions 20A and the interlocking portion 20B are connected and connected. A jumper line JP2 is connected to the AC input terminal N of the interlocking unit 20A, and a jumper line JP1 is connected to the AC input terminal L of the interlocking unit 20B. In addition, the wiring shown by the dotted line in FIG. 2 represents that the jumper line in the master unit and the slave unit is connected to an empty terminal that is not connected. As shown in FIG. 4 to be described later, the construction is performed by simply connecting the terminals L and N of the master unit and the terminals L and N of the slave unit to the corresponding wires L and N of the AC power source. It is consideration to make it. By such an easy-to-understand connection method, even if there are empty terminals as shown in FIG. 2 at the terminals L and N of the master unit and the slave units, the terminals L and N of the master unit and the terminals L and N of the slave units Effective wiring between the AC power lines L and N can be easily performed without any trouble (without error).

  The AC input terminal N of the AC power supply is wired to the terminal N of the interlocking unit 20A, and the AC input terminal L of the AC power supply is wired to the AC input terminal L of the interlocking unit 20B. The AC input terminal 2 of the interlocking unit 20A is wired to the current detection terminal 3 of the interlocking unit 20B, and the current detection terminal 3 of the interlocking unit 20A is wired to the AC input terminal 2 of the interlocking unit 20B. Since the current detection unit 23 in which a plurality of diodes are connected in parallel in opposite directions is connected between the terminal N and the current detection terminal 3 of the interlocking unit 20A, the alternating current is transferred from the terminal N to the current detection terminal 3 and current detection. It flows from terminal 3 to terminal N. For this reason, the interlocking unit 20A and the interlocking unit 20B are connected in parallel to the AC power supply.

  An infrared light emitting diode on the primary side of the photocoupler PC1 is connected in parallel to the three diode groups (corresponding to D4 to D6 in FIG. 1) connected in series. In this way, when a current flows through the diode groups D4 to D6 and the relationship of the forward potentials of the three light emitting diodes D4 to D6 × 3> PC1 is established, the photocoupler The phototransistor on the secondary side of PC1 becomes conductive, and the potential at both ends of the load resistor R27 connected to the emitter side rises to almost the power supply voltage. Since this potential is connected to the microcomputer IC2 of the control unit 24, it can be detected that a current has passed through the diode groups D4 to D6. At this time, when the microcomputer IC2 sets the gate potential of the switching element Ql of the illumination LED group of the illumination unit 22 to the L level, the drain becomes the H level, and the gate potential of the switch element PM1 becomes the H level and turns on. A current flows through the LED group and the illumination unit 22 is turned on. That is, in FIG. 2, when the human sensor PED1 of the interlocking part A or the interlocking part B detects a person and turns on the LED group of the illumination part 22, a load current flowing through the LED group is generated, and the other current is generated. Since the current flows to the AC power supply via the detection diode group, the illumination LED groups of the interlocking unit 20A and the interlocking unit 20B are lit in an interlocked manner as described above.

  In FIG. 2, reference numeral S1 indicates that when two interlocking luminaires are connected and wired, the two interlocking luminaires are stopped (turned off) from continuing to light based on the current detection output of each current detection unit. This is a cut-off portion provided on the current detection signal line that temporarily cuts off the current detection output by a current detection cut-off signal (not shown) generated by the microcomputer IC2 (not shown). Symbol S2 takes a logical sum of the timer signal based on the human detection signal from the human detection unit 25 and the current detection signal from the current detection unit 23, and uses the logical sum output as a lighting control signal of the switch element Q1. An OR circuit for supplying to the gate.

  Regarding such a mutual control type (interlocking type) human illuminating fixture in which no child unit is disposed between two parent units, the specification of Japanese Patent Application No. 2010-226856 filed on October 6, 2010 by the present applicant. The book (parts related to FIGS. 3 and 4) explains the principle and application.

  Note that the lighting mode switching switch SW1, which is a lighting mode switching unit, has switching terminals corresponding to three selectable modes, and the first switching terminal is set to forcibly turn on for forced continuous lighting. The second switching terminal is a terminal for setting forced off to forcibly continuously turn off the light, and the third switching terminal is automatically turned on and off using a human sensor. This is a terminal for setting automatic operation for turning off the light. The user can set the manual switching with the lighting mode switch SW1 in advance. Which mode is selected and set can be known from a character (logo) printed at a selected position such as a slider of the changeover switch SW1.

  In the interlocking luminaire described above, when the surroundings become dark and the ambient environment illuminance becomes, for example, 30 Lx or less, based on the detection output of the illuminance sensor unit 12 of the independent unit 10A (and the illuminance sensor unit 26 of the interlocking unit 20A). When the thyristor SCR1 is turned on, the night-light illumination unit 13 including the lower (foot) side LED group is turned on, and when a person comes, the motion sensor unit 25 in the interlocking unit 20A detects this and the control unit 24 operates. Thus, the switching element Q1 is turned on, and the illumination unit 22 including the LED group on the main surface (for example, front) side of the interlocking unit 20A is turned on. When the illuminating unit 22 of the interlocking unit 20A is turned on, the current from the AC power source flows through the current detection unit 23 of the other interlocking unit 20B in the next AC half cycle. The switching element Q1 is turned on, and the illumination unit 22 including the main surface (for example, front) side LED group of the interlocking unit 20B is turned on. As a result, the interlocking unit 20A and the interlocking unit 20B are automatically turned on in conjunction with the human sensor output of one interlocking unit. The interlocking unit 20A and the interlocking unit 20B constitute first and second interlocking luminaires as master units, respectively.

  FIG. 2 schematically shows the configuration of an interlocking lighting system, which is a lighting fixture with a human sensor, in which two master units are connected to each other. Next, referring to FIG. A child lighting device (hereinafter referred to as a child device) that can be connected and used will be described.

FIG. 3 shows a detailed configuration diagram of the slave unit in the interlocking illumination system.
The child device has the presence of the presence sensor unit 25 of the parent device shown in FIG. 1 and a current detection unit 43 in which a plurality of diodes for detecting a current flowing during LED lighting are connected in parallel in opposite directions from an AC power source. Being independent, the illumination unit 42 forms a main illumination unit by a front LED group in which six LEDs of a plurality (eight in the figure) of LED groups are the main light sources, and the remaining two LEDs Is different from the interlocking unit 20A or the interlocking unit 20B that is a parent device in that a sub-illumination unit is formed by a bottom LED group that is a sub-light source.

The slave unit includes a power supply unit 41, an illumination unit 42, a current detection unit 43, a control unit 44, and an illuminance sensor unit 45.
The power supply unit 41 has substantially the same configuration as the power supply unit 21 of FIG. That is, the power supply unit 41 has the same configuration as that in which the capacitor C1 is added to the power supply unit 21 and the neon tube NE1 and the resistor R5 are omitted.

  As described above, the illumination unit 42 divides the LED group for illumination into two lighting surfaces in different illumination directions, that is, a front LED group and a bottom LED group, and is different from the configuration of the illumination unit 22 of the interlocking unit 20A. Is different.

  The current detection unit 43 is different from the configuration of the illumination unit 22 of the interlocking unit 20A in that the current detection unit 43 is independent from the AC power supply without being connected to the AC input terminal N or L of the AC power supply as described above.

The control unit 44 has the same configuration as the control unit 24 of the interlocking unit 20A.
The illuminance sensor unit 45 is arranged in the control unit 44, but has the same configuration as the illuminance sensor unit 26 of the interlocking unit 20A.

Next, with reference to FIG. 4, how the LED illumination current generated on the parent unit side flows in the current detection unit 43 will be described.
FIG. 4 shows a wiring diagram of a connection form of two master units and a plurality of slave units. As an example, a state in which three slave units are connected between the master units 20A and 20B is shown. The AC input terminal 2 of the parent device 20A is wired to the current detection terminal 3 of the parent device 20B, the current detection terminal 3 of the parent device 20A is connected to the current detection terminal 2 of the child device 20C1, and the current detection terminal 3 of the child device 20C1 is The current detection terminal 2 of the child device 20C2 is wired to the current detection terminal 2 of the child device 20C3, and the current detection terminal 3 of the child device 20C3 is wired to the AC input terminal 2 of the parent device 20B. The That is, each current detection unit is connected in series. For this reason, the current that flows when the illumination LED group in the parent device 20A or the parent device 20B is lit flows through each current detection unit. As a result, the current detection signal is detected by the microcomputer IC2 of each control unit, and each LED group for illumination is turned on. That is, a plurality of LED groups are turned on simultaneously in conjunction with each other.

  As shown in FIG. 4, whether or not the wiring is correctly performed can be easily confirmed by lighting the neon tube NE1 on the parent side in FIG.

  FIG. 5 is a timing chart for explaining the operation of simultaneously lighting and simultaneously turning off all the lighting fixtures installed in FIG.

  As for the mutual control type (interlocking type) human illuminating device in which the sub unit is arranged between the two main units as shown in FIG. 4, Japanese Patent Application No. 2010-226857 filed on October 6, 2010 by the present applicant. There is a description of the principles and applications in the specification (parts related to FIGS. 5 and 6).

  It should be noted that the microcomputer IC2 of either parent device 20A or 20B has a timer function for generating a timer signal for a predetermined time based on a human detection signal from the human detection sensor PED1, and two human detection sensors. In order to eliminate the phenomenon that the interlocking lighting fixtures 20A and 20B continue to be turned on based on the current detection output of each current detector 23, the timer signal generated in the second interlocking lighting fixture with human sensor 20B is turned off. And a function of generating a current detection cutoff signal based on the timing.

  Next, with reference to FIG. 5, a description will be given of turning off a plurality of LED groups that are once turned on in conjunction with each other.

  Assuming that the human sensor PED1 of the parent device 20A reacts to turn on the LED group, a current detection signal is also generated in the parent device 20A and also in the parent device 20B. At the same time, it also occurs in the slave units 20C1 to 20C3 in the middle (hereinafter simply referred to as the slave unit 20C), and the LEDs of the master unit 20B and the slave unit 20C are lit. The parent device B holds the right to turn off at the same time that the LED group is turned on by the current detection signal. Here, the right to turn off the LED means the right (right) to turn off the LED. In this case, it is assumed that the right to turn off the LED cannot be held on the side of the parent device 20A that has turned on the LED group by the reaction of the human sensor PED1. As a simple case, when a person reaches the parent device 20B, the human sensor PED1 of the parent device 20B reacts to start a timer by a program in the microcomputer IC2 of the parent device 20B. When the LED group is turned off at the same time as the time is up, the LED lighting current series circuit portion wired between the master unit 20A, the slave unit 20C and the master unit 20B is cut off and the current does not flow, and the current detection of the master unit 20A and the slave unit 20C The output of the unit becomes L level, and the LED groups of the parent device 20A and the child device 20C are also turned off.

  In the master unit 20A, a timer based on the program of the microcomputer IC2 of the master unit 20A is started simultaneously with the lighting of the LED group, but this timer time is relatively long. That is, if for some reason the person who has reacted the human sensor PED1 of the parent device A does not reach the parent device 20B and returns to the parent device 20A again, the right to turn off the LED does not occur. The group remains lit. For this reason, in order to turn off the LED group even in the case where the right to turn off does not occur, a relatively long time timer is provided for spontaneously forcibly turning off the LED group. This long-time timer is reset once the LED turn-off right is executed.

  According to the first embodiment, it is possible to set and automate an appropriate lighting environment for a user by using a human sensor and an illuminance sensor for detecting ambient illuminance. It is possible to realize an interlocking illumination system that can safely pass through and can illuminate only for a necessary time. Since the time for which the LED lighting is turned on is determined by the speed of the person moving between the parent devices A and B, it is different from the conventional lighting control that lights only for the unilaterally set time. It is effective to use it as a passage light or staircase light in a house where people with disabilities are living.

[Second Embodiment]
FIG. 6: has shown the circuit diagram of the interlocking type lighting fixture as a master in the interlocking type lighting system of the 2nd Embodiment of this invention.
The difference between the interlocking lighting fixture as the parent device in FIG. 6 and the interlocking lighting fixture as the parent device in FIG. 1 is that the PD touch illuminance sensor unit 26 generates a command for dimming the brightness of the illumination. Instead, a mode switching command is generated to switch the lighting mode (forced lighting, forced extinction, and automatic lighting based on human feeling on the interlocking unit 20A or 20B side) based on a finger operation. The microcomputer IC2 in the control unit 24 sequentially turns on each lighting mode from the three output terminals of the IC2 every time the mode switching command output from the PD touch illuminance sensor unit 26 as the lighting state setting unit is input. The mode switching signal is generated and output, supplied to the indicator unit 27 for displaying the lighting mode, and at the same time, the lighting control signal is generated and output for each lighting mode, and the switch element in the lighting unit 22 of the lighting LED group Supply to the gate of Q1.

  In the indicator unit 27, the supplied mode switching signal is supplied to the bases of the driving transistors Q4, Q5, and Q6 connected in series to the lighting mode instruction LEDs 6, LED7, and LED8, respectively, and the LED6 for each switched lighting mode. , LED7 and LED8 are sequentially turned on. The LED 6, LED 7, and LED 8 can emit, for example, red, orange, and green color lights, and display the lighting modes for each color, so that the user can be informed of the switched lighting mode. At the same time, the lighting unit 22 is controlled to be lit by a lighting control signal for each switched lighting mode, and any one of forced lighting, forced lighting, and automatic lighting by human feeling on the interlocking unit 20A or 20B side is executed. The

  Other configurations and operations are the same as those in FIG.

FIG. 7: has shown the circuit diagram of the interlocking type lighting fixture as a subunit | mobile_unit in the interlocking type lighting system of the 2nd Embodiment of this invention.
The interlocking lighting fixture as the slave unit in FIG. 7 is different from the interlocking lighting fixture as the slave unit in FIG. 3 in that the secondary lighting unit includes a power source unit 31, an illuminance sensor unit 32, and a secondary light source lighting unit 33. As in the case of FIG. 6, the illuminance sensor unit 45 for PD touch does not generate a command for dimming the brightness of the illumination, but generates a lighting mode (forced). A mode switching command is generated for switching the lighting, forced extinction, and automatic lighting modes linked to automatic lighting by human feeling on the interlocking unit 20A or 20B side based on a finger operation.

  The microcomputer IC2 in the control unit 44 sequentially turns on each lighting mode from the three output terminals of the IC2 every time the mode switching command output from the illuminance sensor unit 45 for PD touch as the lighting state setting unit is input. The mode switching signal is generated and output, supplied to the indicator unit 51 for displaying the lighting mode, and at the same time, the lighting control signal is generated and output for each lighting mode, and the switch element in the lighting unit 42 of the lighting LED group Supply to the gate of Q1.

In the indicator unit 51, the supplied mode switching signal is supplied to the bases of the driving transistors Q4, Q5 and Q6 connected in series to the lighting mode instruction LEDs 6, LED7 and LED8, respectively. , LED7 and LED8 are sequentially turned on. The LED 6, LED 7, and LED 8 can emit, for example, red, orange, and green color lights, and display the lighting modes for each color, so that the user can be informed of the switched lighting mode. At the same time, the lighting unit 42 is controlled to be lit by a lighting control signal for each switched lighting mode, and is either forced lighting, forced lighting, or automatic lighting linked to automatic lighting by human feeling on the interlocking unit 20A or 20B side. Mode is executed.
Other configurations and operations are the same as those in FIG.

  According to the second embodiment described above, it is possible to set and automate an appropriate lighting environment for the user by using the human sensor and the illuminance sensor for detecting the ambient illuminance, and the person can always perform the corridor and the stairs. Thus, it is possible to realize an interlocking illumination system that can safely pass through a passage and the like and can illuminate only for a necessary time. Since the time for which the LED lighting is turned on is determined by the speed of the person moving between the parent devices A and B, it is different from the conventional lighting control that lights only for the unilaterally set time. It is effective to use it as a passage light or staircase light in a house where people with disabilities are living.

[Third embodiment]
FIG. 8 shows a circuit diagram of the interlocking luminaire in the interlocking illumination system of the third embodiment of the present invention. Here, the circuit diagram comprised with the interlocking signal 2-wire type LED lighting fixture which developed the interlocking type lighting fixture newly is shown.

  The power supply unit 61 uses the power transformer PT so that the primary side AC100V side and the secondary side of the power transformer are insulated. On the secondary side of the power transformer PT, the output is full-wave rectified by the rectifier diode bridge DB and smoothed to DC12V by the Zener diode ZD1 and the electrolytic capacitor C1. This 12V power supply is stepped down to a control power supply + 5V by a three-terminal regulator IC1 to obtain a stabilized DC power supply.

In the human sensor unit 63, the output of the human sensor PED1 is amplified by about 60 db by two operational amplifiers IC2 and IC3, and the output is input to the AD conversion input terminal of the microcomputer IC5 as the arithmetic unit. In the illuminance sensor unit 64, the output of the illuminance sensor IC4 is also input to another AD conversion input terminal of the microcomputer IC5.

  In the microcomputer IC5, the output of the illuminance sensor IC4 is AD-converted, and if the human sensation signal is significant at a constant environmental illuminance, for example, 30Lx or less, the shutdown input terminal SHDN of the LED driver IC6 as the drive unit 66 is set to H level. The LED driver IC 6 is enabled, and the LED group as the illumination unit 67 in which a plurality of LEDs are connected in series is lit.

  As an information transmission unit that outputs information indicating that the LED group is lit, transmits the information to another identical interlocking lighting fixture 20B (not shown), and causes the LED group of the interlocking lighting fixture 20B to be interlockedly lit. The signal transmission unit 62 includes a phototransistor output type photocoupler PC, a transistor Q1 that controls an infrared diode on the primary side of the photocoupler PC, information on the output side of the photocoupler PC, and a base side of the transistor Q1 And a NOR gate for transmitting the logical product of the control signal to the microcomputer IC5. The signal transmission unit 62 has a function of generating lighting information based on the human detection signal from the human detection sensor PED1, and transmitting the information between the lighting fixtures using two signal lines.

FIG. 9 shows a portion in which the signal transmission parts 62 of the interlocking lighting fixture 20A and the interlocking lighting fixture 20B are connected to each other by two signal lines instead of a power supply line , and FIG. 10 discloses a time chart.

  In the first and second embodiments, the signal transmitted between the master unit and between the slave unit and the master unit is a transmission signal that is an increase or decrease in the current value of one AC100V line. The book was a three-wire system. On the other hand, in the third and fourth embodiments, the signal transmitted between the master units and between the slave units and the master unit has two signal lines in a manner of transmitting a pulse signal, and the lighting fixture body Then, it is a 4-wire system with two AC100V lines and two signal lines.

  Below, the principle that the two lighting fixtures are turned on and off in conjunction with each other will be described with reference to FIGS. The lighting fixtures 20A and 20B are in a state in which the COM terminal and the COM terminal are connected between each SIG terminal and the SIG terminal.

With reference to FIG. 8 and FIG. 9 , when a person comes in an environment where the lighting fixtures 20 </ b> A and 20 </ b> B are to be turned on at a certain illuminance or less, the human sensor PED <b> 1 of the lighting fixture on the 20 </ b> A side operates, It is assumed that the human sensor output is input to the IN1 terminal of the microcomputer IC5 , the LED lighting command signal SHDN is generated as the output OUT1 from the microcomputer IC5 , and the LED group is turned on. At this time, the output OUT2 of IC5 is conductive becomes transistor Q1 for a predetermined period H level. At the same time, the photocoupler PC is turned on and the phototransistor on the output side thereof is turned on, so that the G1 terminal of the NOR gate becomes L level, but the other terminal G2 is connected to OUT2 of the microcomputer IC5, so that H At the level, the output of the NOR gate remains at the L level and the IN2 terminal of the microcomputer IC5 remains at the L level and does not change.

On the other hand, the primary side of Fotoka flops la PC of 20B side becomes conductive via the transistor Q1 of the 20A side, so phototransistor on the output side becomes conductive, G1 inputs of NOR gate 20B side has an L level. At this time, since no person has arrived on the 20B side and no human sensor output is generated, the OUT2 output of the microcomputer IC5 of the 20B remains at the L level, so the input terminal G2 of the NOR gate is at the L level and the NOR gate The output rises to the H level, the output is applied to the IN2 terminal of IC5, and the LED group on the 20A side is judged to be in the lighting state, so that the LED lighting command signal is output as the output OUT1 of the IC5 , The LED is also lit. If the 20A side is lit in this way, the LED group can be lit in conjunction with the 20B side.

The side that is first lit by the human sensor output (here 20A side) is referred to as a master, and the side that is lit by a lighting signal from the master side is referred to as a slave.

  Eventually, a case where a person detected by the human sensor on the 20A side arrives on the 20B side and is detected by the human sensor on the 20B side will be described below.

When the human sensor becomes significant on the 20B side (slave side), the LED group is changed from the lighting state to the extinguishing mode. Further, the OUT2 output of the microcomputer IC5 becomes H level and the transistor Q1 is turned on. In this case, becomes conductive Fotoka flops la PC on the primary side of an infrared diode, although the collector potential phototransistor of the output side is turned ON at the L level, the other input G2 of the NOR gate for conducting Q1 NOR gate output for has become H level (Yes in no signal for the 20B side microcomputer IC5) to the L level, LED oFF command signal as the output OUT1 of IC5 is output, the LED group 20B side Turn off the light.

On the other hand, G1 inputs of the NOR gate becomes L level phototransistor on the output side for the primary side of Fotoka flops la PC of 20A side is conductive is turned on. At this time, G2 input Ri Contact becomes L level since IN1 to human sensor output of the microcomputer IC5 is absent, NOR gate output becomes H level. When the NOR gate output changes to H level, the master side outputs a command (LED extinguishing command signal) to turn off the LED group as output OUT1, and turns off the master side LED group.
In this way, the LED groups can be turned off simultaneously in conjunction with 20A and 20B.

FIG. 11 shows a circuit diagram of a slave unit in the third embodiment. The child unit 20C does not have a human sensor unit with respect to the parent unit having the human sensor unit described above, and is an information transmission unit INF1 for transmitting information on the state of the parent unit between the parent units 20A and 20B. There are two INF2 circuits. FIG. 12 shows a portion related to information transmission when one slave unit is connected between the master units 20A and 20B. FIG. 13 shows a time chart.

The operations of the parent devices 20A and 20B are as described above, and how the child devices transmit parent device information will be described below.
When the human sensor PED1 detects a person on the parent device 20A (see FIG. 8), an H level OUT2 signal (see FIGS. 8 and 12) is output from the microcomputer (IC5 in FIG. 8) to the base of the transistor Q1 on the 20A side. The Q1 is turned on for a certain period. As a result, the primary-side infrared diode of the photocoupler PC of the master 20A is turned on and the secondary-side phototransistor is turned on. Therefore, the NOR input G1 becomes L level, but the G2 input is H level, so NOR. The output remains at the L level and there is no signal to the microcomputer (IC5 in FIG. 8).

On the other hand, since the infrared diode on the primary side of the photocoupler PC1 on the slave unit 20C side (see FIG. 12) becomes conductive, the phototransistor on the output side is turned on, so that the input G1 of NOR1 becomes L level. Further, since the G2 input remains at the L level, the output of NOR1 becomes the H level and is applied to the O1 terminal of the microcomputer IC8, and the information detected by the human sensor PED1 on the parent device 20A side is transmitted to the child device 20C. As a result, the OUT1 terminal of the microcomputer IC8 on the slave unit 20C side becomes H level and the control terminal of the LED driver IC (IC9 in FIG. 11) becomes H level, so that the LED driver IC9 operates and the LED for illumination Turn on the group.

In order to transmit this result, the D2 terminal of the microcomputer IC8 becomes H level, the transistor Q2 is turned on, and the SIG2 terminal (see FIG. 11) becomes L level.

At this time, to conduct the primary side of the infrared diode Fotoka flops la PC2, the secondary side of the photo-transistor is also turned on to NOR2 gate of G3 terminal L level, but since the D2 terminal of the microcomputer IC8 is H level, the NOR gate The G4 terminal is at H level, the output of NOR2 is at L level, and no signal is sent to the microcomputer IC8.

Thus the transistor Q2 is turned on, and conducts Fotoka flops la PC on the primary side of the infrared diode master unit 20B conducts phototransistor on the output side, G1 terminal of the NOR gate becomes L level. Further, since the OUT2 signal from the microcomputer on the 20B side is at the L level because the human sensor does not detect a person, the G2 terminal of the NOR gate is also at the L level, so the NOR output becomes the H level and the 20B (FIGS. 12 and 9), a predetermined terminal IN2 input of the microcomputer IC5 connected to the NOR output terminal changes to H level, and the illumination LED group of the parent device 20B is turned on based on this signal.

  When a person is detected in the parent device 20A in this way, the LED group of the parent device 20A is turned on, a signal is transmitted to the child devices 20C and 20B, and each LED group is turned on one after another.

  Next, when a person detected by the master unit 20A passes through the slave unit 20C and reaches the master unit 20B, it is detected by a human sensor of the master unit 20B. A process in which information transmission similar to the process described above is transmitted from the master unit 20B to the master unit 20A via the slave unit 20C will be described below.

  When the microcomputer IC5 of the master unit 20B detects a person, the LED group of the 20B enters the extinguishing mode, and an H level OUT2 signal output is output from the microcomputer IC5 for a certain period. As a result, the transistor Q1 of the parent device 20B is turned on, but the primary side infrared diode of the photocoupler PC of the same 20B is also turned on, the output side phototransistor is also turned on, and the G1 terminal of the NOR gate becomes L level. Since the G2 terminal is at the H level, the NOR output remains at the L level and there is no signal to the microcomputer.

  When the transistor Q1 of 20B is turned on, the infrared diode on the primary side of the photocoupler PC2 of the slave unit 20C is turned on, the phototransistor on the output side is turned on, and the G3 terminal of the NOR2 gate becomes L level. On the other hand, since the D2 output of the microcomputer IC8 is at the L level, the NOR2 gate G4 is at the L level and the output of NOR2 is at the H level, and it is transmitted that the parent device 20B has detected a person.

  As a result, the LED group (not shown) of the slave unit 20C is turned off, and at the same time, the D1 terminal of the microcomputer IC8 becomes H level for a certain period, and the transistor Q1 is made conductive. At this time, the infrared diode on the primary side of the photocoupler PC1 is also turned on, and the phototransistor on the output side is turned on, and the G1 terminal of the NOR1 gate becomes L level. However, since D1 is H level, the NOR1 output is L level. Remains.

  As the transistor Q1 of the slave unit 20C is turned on, the primary side infrared diode of the photocoupler PC of the master unit 20A is turned on and the output side phototransistor is turned on. Therefore, the G1 terminal of the NOR gate is at the L level, while the G2 terminal Since the signal remains at the L level, the NOR output changes to the H level, the information that the parent device 20B detects the person is transmitted to the microcomputer IC5 of the parent device 20A, and the LED group is turned off.

Thus, when a person is first detected by the master unit 20A, the illumination LED of the master unit 20A is lit, the result is transmitted to the slave unit 20C and the master unit 20B, and each illumination LED is lit one after another, Next, when the parent device 20B detects a person, the illumination LED of the parent device 20B is turned off, and the result is transmitted to the child device 20C and the parent device 20A, and the respective illumination LEDs are turned off one after another.

  According to the third embodiment, it is possible to set and automate an appropriate lighting environment for a user by using a human sensor and an illuminance sensor for detecting ambient illuminance, and a person always has a passage such as a corridor or a staircase. It is possible to realize an interlocking illumination system that can safely pass through and can illuminate only for a necessary time. Since the time for which the LED lighting is turned on is determined by the speed of the person moving between the parent devices A and B, it is different from the conventional lighting control that lights only for the unilaterally set time. It is effective to use it as a passage light or staircase light in a house where people with disabilities are living.

[Fourth Embodiment]
FIG. 14 shows a circuit diagram of the master unit in the interlocking illumination system of the fourth embodiment of the present invention. Compared to FIG. 8 of the third embodiment, the fourth embodiment has two human sensor units. In other words, in FIG. 14, a human sensor is provided by adding another human sensor 68 in addition to the human sensor 63 to the interlocking lighting fixture as the master unit 20A shown in FIG. The units 63 and 68 (including human sensors PED1 and PED2 respectively) are assumed to have two circuits. The other configuration is the same as that of FIG.

  Regarding the arrangement of the human sensor units 63 and 68 on the passage, for example, at this time, the two human sensor units are separated from each other along the passing direction through which the person passes so that the two human sensor units do not detect one human body at the same time. As described above, a separator exists between the human sensors of the two human sensor units. For this reason, if a human body passes in front of the interlocking type lighting fixture 20A of this embodiment, a time difference will arise in each detection output of two human sensitive sensors. In addition, it is good also as a structure using not only two human sensors but two or more human sensors.

By preparing the same interlocking lighting fixture 20B (not shown) as the interlocking lighting fixture 20A shown in FIG. 14 and connecting the two signal lines (+ SIG, COM) to each other, the two lighting fixtures 20A, A case will be described in which 20B is connected to form one interlocking lighting system, and a human body passes through the lighting fixture 20A and reaches the lighting fixture 20B. It should be noted that at least one interlocking luminaire as a slave unit (for example, a slave unit as shown in FIG. 11) is connected between the two lighting fixtures 20A and 20B as the master unit. A system may be configured. The human sensors PED1, PED2 of the interlocking lighting fixture 20A are disposed so as to be positioned on the side near the outer peripheral side and the inner side of one end side in the lighting area including the passage between the lighting fixtures, respectively. The 20B human sensors PED2 and PED1 are arranged so as to be positioned on the inner side on the other end side and the side closer to the outer peripheral side in the illumination area including the passage between the lighting fixtures.

When a person passes in front of the lighting fixture 20A, the output of the human sensor PED1 occurs before the output of the human sensor PED2. At this time, the output to Q1 of the microcomputer IC5 as the calculation unit is a single pulse output with a pulse width Ta. This signal is transmitted to a microcomputer as a calculation unit of the lighting fixture 20B. The contents of the overwritable register of the microcomputer IC5 of the lighting fixtures 20A and 20B are incremented to +1. When this register is 1 or more, it is assumed that the instruction is to turn on the LED illumination. This is because if the value of the register is 1 or more, it can be determined that there is a person in the illumination area, for example, a passage. Reaches this person eventually luminaire 20B, when passing in front of 20B, since PED2 the luminaire 20B detects a human body before the PED1, of determining that person from luminaire 20B comes 20B of the microcomputer IC5 The output to Q1 is a double pulse output with a pulse width Ta spaced at intervals of Ts . When the two series of pulse outputs are transmitted, if the contents of the registers of the lighting fixtures 20A and 20B are decremented, the contents of the registers are decremented by 1 and cleared to zero. When this register content becomes 0, it means that there is no person on the passage that is the illumination area, and therefore it is an instruction to turn off the LED illumination.

  FIG. 15A shows the outputs of the human sensors PED1 and PED2 when a person enters between the master units 20A and 20B (for example, enters 20A) and the output from the microcomputer IC5 to the transistor Q1 at that time. . FIG. 15B shows the outputs of the human sensors PED2 and PED1 when a person comes out between the master units 20A and 20B (for example, comes out of 20B) and the output from the microcomputer IC5 to the transistor Q1 at that time. .

  In the above description, the case where a person passes in front of the master unit 20A and reaches 20B has been described, but conversely, the case where the person passes in front of the master unit 20B and reaches 20A is the same.

  As an example of a special example, consider a case in which a route that passes in front of the lighting fixture 20A and reaches the lighting fixture 20B is changed, and a U-turn is made to 20A.

  Since it passed in front of the lighting fixture 20A, a Ta pulse is output to the transistor Q1 of 20A, this pulse signal is transmitted to the lighting fixture 20B, and the contents of the registers of each microcomputer are incremented to become +1. The LED illumination of 20B is turned on.

  Eventually, since it returned to 20A again, the 20A human sensor detects PED2 first, so the output to Q1 will output two Ta pulses. Communicated. If it is an instruction to decrement a register if it is a double pulse, the contents of each register are cleared by -1, so the LED illumination is turned off.

  Next, consider a case where there is a period in which a person passes in front of 20A, another different person passes in front of 20B, and two persons between 20A and 20B exist simultaneously.

When a person passes through 20A, a pulse Ta is transmitted to 20B, and the register of each microcomputer IC5 is incremented to become +1. Thereafter, a person passes through 20B and a pulse Ta is generated and transmitted to 20A, and the registers of both microcomputer IC5 are incremented to +2. Eventually both people passing, human from 20A reaches the 20B, 2 consecutive pulses Ta is generated in the 20B, is transmitted to 20A, each register is decremented contents is changed to +1. Subsequently, a person from 20B reaches 20A, and two series of Ta pulses are generated in 20A and transmitted to 20B. The contents of each register are decremented and cleared, and the LED illumination is turned off. .

  In FIG. 15, the pulse output when a person comes out between the master units 20A and 20B is a plurality of continuous pulses (for example, double pulse), but as shown in FIG. 16, a person comes out between the master units 20A and 20B. The pulse output may be changed with respect to the pulse width Ta of the pulse output when a person enters between 20A and 20B. For example, with respect to the pulse width Ta, the pulse width of the pulse output when a person comes out may be widened as Tb (Ta <Tb).

  FIG. 16A shows the outputs of the human sensors PED1 and PED2 when a person enters between the master units 20A and 20B (for example, enters 20A) and the output from the microcomputer IC5 to the transistor Q1 at that time. . FIG. 16B shows the outputs of the human sensors PED2 and PED1 when a person comes out between the master units 20A and 20B (for example, comes out of 20B) and the output from the microcomputer IC5 to the transistor Q1 at that time. . That is, instead of distinguishing the pulse output when a person goes out by changing the number of pulses, the pulse output may be distinguished by changing the pulse width.

  According to the fourth embodiment, it is possible to set and automate an appropriate lighting environment for a user by using a human sensor and an illuminance sensor for detecting ambient illuminance, and a person always has a passage such as a corridor or a staircase. It is possible to realize an interlocking illumination system that can safely pass through and can illuminate only for a necessary time. Since the time for which the LED lighting is turned on is determined by the speed of the person moving between the parent devices A and B, it is different from the conventional lighting control that lights only for the unilaterally set time. It is effective to use it as a passage light or staircase light in a house where people with disabilities are living. It is also possible to deal with a special case such as a case where a person passes in front of one parent device and changes the route to reach the other parent device and makes a U-turn to the first parent device.
