Description

  The present invention relates to a lighting device including a human sensor that detects the presence or absence of a human body.

  2. Description of the Related Art Lighting devices that automatically turn on / off lighting fixtures by detecting the presence or absence of a human body by detecting heat rays emitted from a human body with a heat ray sensor (human sensor) such as a pyroelectric element are widely used. . In general, this type of lighting device is configured to turn off the lighting fixture after a predetermined period (delay time) from when the presence of the human body is not detected after detecting the presence of the human body and turning on the lighting fixture. ing. And since the lighting fixture is lighted in the state where the human body does not exist during the predetermined period, the power consumption of the lighting fixture is wasted.

  As a means to eliminate this waste of power consumption, a sensor-equipped luminaire has been proposed that forcibly turns off the luminaire by, for example, operating a dedicated switch placed on the wall when leaving the room. (For example, refer to Patent Document 1).

Also, a lighting device with a human body detection function is proposed in which at least lighting devices are turned on based on detection of a heat ray sensor, and lighting devices are turned off based on a manual switch turning-off operation, such as when leaving a room or sleeping. (For example, see Patent Document 2).
Japanese Patent Laid-Open No. 11-185977 (page 4, FIG. 1) Japanese Patent Laid-Open No. 2001-237085 (page 3, FIG. 1)

  Patent Document 1 and Patent Document 2 have an advantage that waste of power consumption of the lighting apparatus when no human body exists can be eliminated. However, there is a disadvantage that the illumination load is not lit unless the heat ray sensor moves to a region where a human body is detected. That is, there is a demand for lighting lamps to be turned on before the heat ray sensor detects a human body, as well as eliminating waste of power consumption of the lighting apparatus.

  An object of this invention is to provide the illuminating device which comprises the human sensitive sensor which can make a lighting load light forcibly and can make a light load light-extinguish.

  The invention of the lighting device according to claim 1 includes: an illumination load; an external operation means for turning on or off the illumination load; a human sensor for detecting a human body; and a human body when the human sensor detects the human body. The lighting load is controlled by outputting a control signal according to the presence of the human body, and the control signal according to the absence of the human body is output when the human body is not detected again within the first predetermined period from the detection time point. Sensor control means for controlling the illumination load; when a manual operation for turning on the illumination load is performed by the external operation means, the illumination load is forcibly lit for a certain period, and the illumination load is turned off or adjusted by the external operation means. The illumination load is forcibly turned off or dimmed when a manual operation is performed, and the control by the sensor control means is stopped for a second predetermined period from the time of the manual operation, and the second Predetermined period Characterized in that it comprises a; and the external operation control means for releasing the stopped after elapse.

  In the present invention and the following inventions, each configuration is as follows unless otherwise specified.

  The external operation means allows a switch such as a wall switch and a pull switch, and a remote controller, for example.

  The control signal according to the absence of the human body output from the sensor control means may be to stop the control signal according to the presence of the human body continuously output. That is, the control signal according to the absence of the human body may be output from the sensor control means that the control signal according to the presence of the human body is not output.

  Further, the sensor control means may be configured to perform dimming control of the illumination load by a control signal corresponding to the presence or absence of a human body in addition to turning on / off control. That is, the sensor control means turns on the illumination load by outputting a control signal corresponding to the presence of the human body. The dimming rate of the illumination load at this time may be a preset dimming rate, and the dimming rate is changed so that the illumination area has a constant brightness according to the detection signal of the illuminance sensor. It may be. Then, by outputting a control signal according to the absence of the human body, the illumination load is turned off or dimmed.

  “Stop the control by the sensor control means” means that the illumination load is not turned off or turned on from the dimming state even if the human sensor detects the human body. “Release the stop” means that when the human sensor detects a human body, the sensor control means outputs a control signal corresponding to the presence of the human body to turn on the lighting load, and within a first predetermined period. This means that when the human body is not detected again, a control signal corresponding to the absence of the human body is output to turn off or dimm the lighting load.

  According to the present invention, when a manual operation for turning on the illumination load is performed by the external operation means, the illumination load is forcibly lit for a certain period. Further, when a manual operation for turning off or dimming the illumination load is performed by the external operation means, the illumination load is forcibly turned off or dimmed, and the human sensor detects the human body within the second predetermined period. The lighting load is turned off or dimmed.

  According to a second aspect of the present invention, there is provided a lighting device according to the first aspect, further comprising setting means for setting the first and second predetermined periods.

  The setting means allows setting by a manual operation setting unit or a remote controller.

  When the human body detection frequency by the human sensor is large, the first predetermined period is set to a long time, and when the human body detection frequency is low, setting the first predetermined period to a short time is resource saving. It is desirable from the viewpoint of power saving. That is, when the human sensor detects the human body frequently and the first predetermined period is short, the number of times the lighting load blinks increases, which may shorten the life of the lighting load. In addition, for example, if the lighting load is turned off when the user leaves the desk for a short period of time, there is a risk that the person may feel uncomfortable or uncomfortable. On the other hand, if the human body detection frequency of the human sensor is low and the first predetermined period is a long time, the time during which the illumination load is lit may be increased in the absence of a person in the room. There is a problem that power consumption in the first predetermined period is wasted.

  Then, in order to eliminate the waste of power consumption during the first predetermined period, the illumination load is forcibly turned off or dimmed over the second predetermined period. Here, if the second predetermined period is short, for example, the second predetermined period is timed up before leaving the room, and the human sensor may detect the human body. Further, if the second predetermined period is long, for example, there is a problem that a period during which the illumination load is not turned on may be long for a person who has entered the room within the second predetermined period. Therefore, it is preferable to appropriately set the first and second predetermined periods in accordance with the human body detection frequency by the human sensor.

  According to the present invention, the first and second predetermined periods are respectively set by the setting means in accordance with the human body detection frequency by the human sensor.

  According to the first aspect of the present invention, when a manual operation for turning on the illumination load is performed by the external operation means, the illumination load is forcibly lit for a certain period, so that it is possible to move in the dark, for example. Therefore, it is easy to move to the detection area of the human sensor, and when the illumination load is lit when the detection area of the human sensor is reached, a sense of incongruity can be prevented. In addition, when a manual operation for turning off or dimming the illumination load is performed by the external operation means, the illumination load is forcibly turned off or dimmed over the second predetermined period. It is possible to eliminate unnecessary power consumption due to the lighting of.

  According to the invention of claim 2, the lighting control by the human sensor is made effective by appropriately setting the first and second predetermined periods according to the use environment such as the human body detection frequency by the human sensor. Can be used.

That is, the remote control transmitter 22 is also used as an external operation means. Also, a reply signal such as the lighting state of the fluorescent lamp 7 and the first and second predetermined periods sent from the main control unit 32 is sent to the remote control transmission unit 24 and transmitted from the remote control transmission unit 24 to the remote control transmitter 22.

The component placement unit 19 does not include the remote control reception unit 23, the remote control transmission unit 24, and the faders 20 and 21 as setting means shown in FIG. Then, in the sensor device main body 12 of the sensor devices 3 and 4 of the slave units, a detection signal when a human body is detected by the human sensor 25 is sent to the illumination control device 26 of the sensor device 2 of the master unit. A signal transmission device 40 is provided. Here, the same reference numerals are used for the same parts as the sensor device 3 of the master unit.

  As shown in FIG. 5, the detection signal transmission device 40 includes a rectifier 41, a power supply unit 42, a human sensor interface (I / F) unit 43, a transmission signal generation unit 44, and an N-type bipolar transistor Tr1. Has been. The human sensor 25 is connected to the human sensor I / F unit 43.

  The input terminal of the rectifier 41 is connected to the communication terminals 45 and 45. The communication terminals 45, 45 are connected to the communication terminals 37, 37 of the illumination control device 26 of the parent sensor device 2 via the signal line 10. Thus, the communication terminals 45 and 45 are supplied with the DC voltage 12V output from the power supply unit 27 (the slave unit / timed off switch communication I / F unit 28) of the lighting control device 26, and the DC voltage is rectified. It is input to 41 input terminals.

  A series circuit of a Zener diode ZD1 and a bipolar transistor Tr1 is connected between the output terminals of the rectifier 41. The base of the bipolar transistor Tr1 is connected to the output side of the transmission signal generator 44 via the resistor R1, and the resistor R2 is connected between the base and the emitter. When the output voltage (transmission signal) of the transmission signal generator 44 is applied to the base of the bipolar transistor Tr1, the bipolar transistor Tr1 is turned on. Here, the Zener voltage of the Zener diode ZD1 is, for example, 7.5V.

  When the bipolar transistor Tr1 is turned on, a current flows from the output terminal on the positive side of the rectifier 41 to the output terminal on the negative side through the series circuit of the Zener diode ZD1 and the bipolar transistor Tr1. As a result, a voltage drop occurs between the communication terminals 45 and 45 due to the rectifier 41 and the Zener diode ZD1, and the voltage between the communication terminals 45 and 45 is reduced from 12V to 9V. This voltage drop is detected by the slave unit / time switch communication I / F unit 28 of the lighting control device 26 on the master unit side. That is, as shown in FIG. 7, a voltage of about 3 V is detected by the slave unit / timed off switch communication I / F unit 28. As a result, the human body detection signal detected by the human sensor 25 of the child device sensor devices 3 and 4 is input to the child device / timed off switch communication I / F unit 28 and further sent to the main control unit 32.

  The power supply unit 42 includes an N-type bipolar transistor Tr2, a Zener diode ZD2, a resistor R3, and a resistor R4. A resistor R3, a resistor R4, and a Zener diode ZD2 are connected between the output terminals of the rectifier 41. As a result, current flows from the output terminal on the positive side of the rectifier 41 to the base of the bipolar transistor Tr2 via the resistors R3 and R4, so that the bipolar transistor Tr2 is always turned on. When the bipolar transistor Tr2 is turned on, driving power is supplied from the rectifier 41 to the human sensor I / F unit 43, the transmission signal generation unit 44, and the like.

  The human sensor I / F unit 43 is configured to send a detection signal to the transmission signal generator 44 when the human sensor 25 detects a human body. The transmission signal generation unit 44 is configured to output the transmission signal to the base of the bipolar transistor Tr1 according to the detection signal. When the transmission signal is applied to the base of the bipolar transistor Tr1 and the bipolar transistor Tr1 is turned on, as described above, the detection signal when the human sensor 25 on the handset side detects the human body is the illumination on the base side. It is input to the slave unit / timed off switch communication I / F unit 28 of the control device 26.

  As shown in FIG. 1, the time-off switch device 5 is connected to the signal line 10 and operates by being supplied with a DC voltage from the signal line 10, similarly to the sensor devices 3 and 4 of the slave units. And according to operation of switch part 5a, an external operation signal transmitter 46 which sends an external operation signal to lighting control device 26 of sensor device 2 of a main unit is provided. This external operation signal is a signal for turning on the fluorescent lamp 7 when the switch section 5a is operated while the fluorescent lamp 7 is turned off, and the switch section 5a is operated when the fluorescent lamp 7 is turned on. Then, a signal for turning off the fluorescent lamp 7 is obtained.

  As shown in FIG. 6, the external operation signal transmission device 46 includes a rectifier 47, a power supply unit 48, a switch determination unit 49, a transmission signal generation unit 50, and an N-type bipolar transistor Tr3. The switch unit 5 a is connected to the switch determination unit 49. When the switch unit 5 a is turned on by manual operation, the switch determination unit 49 is configured to send an on signal to the transmission signal generation unit 50. The transmission signal generation unit 50 is configured to supply an output voltage (transmission signal) to the bipolar transistor Tr3 in response to the ON signal.

  The input terminal of the rectifier 47 is connected to the communication terminals 51 and 51. The communication terminals 51 and 51 are connected to the communication terminals 37 and 37 of the illumination control device 26 of the sensor device 2 of the parent device via the signal line 10. As a result, the communication terminals 51 and 51 are supplied with the DC voltage 12V output from the power supply unit 27 (slave unit / timed off switch communication I / F unit 28) of the lighting control device 26, and the DC voltage is rectified. It is input to 47 input terminals.

  A series circuit of a Zener diode ZD3 and a bipolar transistor Tr3 is connected between the output terminals of the rectifier 47. The base of the bipolar transistor Tr3 is connected to the output side of the transmission signal generator 50 via the resistor R5, and the resistor R6 is connected between the base and the emitter. When the output voltage of the transmission signal generator 50 is applied to the base of the bipolar transistor Tr3, the bipolar transistor Tr3 is turned on. Here, the Zener voltage of the Zener diode ZD3 is, for example, 6.5V.

  When the bipolar transistor Tr3 is turned on, a current flows from the output terminal on the positive side of the rectifier 47 to the output terminal on the negative side through the series circuit of the Zener diode ZD3 and the bipolar transistor Tr3. As a result, a voltage drop occurs between the communication terminals 51 and 51 due to the rectifier 47 and the Zener diode ZD3, and the voltage between the communication terminals 51 and 51 decreases from 12V to 8V. This voltage drop is detected by the slave unit / timed off switch communication I / F unit 28 of the lighting control device 26 on the master unit side. That is, as shown in FIG. 7, a voltage of 4 V is detected by the slave unit / timed off switch communication I / F unit 28. As a result, the manual operation of the switch unit 5a of the timed off switch device 5 is input to the slave unit / timed off switch communication I / F unit 28 as an external operation signal and further sent to the main control unit 32. .

  The power supply unit 48 includes an N-type bipolar transistor Tr4, a Zener diode ZD4, a resistor R7, and a resistor R8. A resistor R7, a resistor R8, and a Zener diode ZD4 are connected between the output terminals of the rectifier 47. As a result, a current flows from the positive output terminal of the rectifier 47 to the base of the bipolar transistor Tr4 via the resistors R7 and R8, so that the bipolar transistor Tr2 is always turned on. When the bipolar transistor Tr2 is turned on, drive power is supplied from the rectifier 47 to the switch determination unit 49, the transmission signal generation unit 50, and the like.

  As described above, in the slave unit / timed off switch communication I / F unit 28 of the lighting control device 26, the human sensor of the sensor units 3 and 4 of the slave units is changed by the change of the DC voltage supplied to the signal line 10. 25 detects the human body detection signal and the timed off switch device 5 external operation signal. That is, the slave unit / timed off switch communication I / F unit 28 always detects the voltage of the signal line 10. Then, as shown in FIG. 7, a minute voltage is detected by driving the slave device sensor devices 3 and 4 and the timed off switch device 5, and by detecting about 3V, the human device sensor devices 3 and 4 are detected. The detection of the human body is detected by the sensor 25, and the detection of 4V detects that the manual operation for turning on or off the fluorescent lamp 7 is performed by the time-off switch device 5. Then, it is sent to the main control unit 32 as a detection signal from the human sensor 25 or an external operation signal from the timed off switch device 5. The slave unit / timed off switch communication I / F unit 28 receives a detection signal detected by the human sensor 25 of the master unit and sends the detection signal to the main control unit 32.

  Next, the operation of the first embodiment of the present invention will be described.

The operation signal is input to the slave unit / timed off switch communication I / F unit 28 of the lighting control device 26, and further input from the slave unit / timed off switch communication I / F unit 28 to the main control unit 32.

  In FIG. 4, when an external operation signal is input from the slave unit / timed off switch communication I / F unit 28 when the fluorescent lamp 7 is turned off, the main control unit 32 supplies the load control I / F unit 35 to the load control I / F unit 35. To output a control signal for turning on the relay 38. The load control I / F unit 35 turns on the relay 38 according to the control signal. When the relay 38 is turned on, an AC voltage from a commercial AC power source is applied between the load terminals 39 of the lighting control device 26, and the AC voltage is disposed in the lighting fixture 6 through the power line 9. Is input. Then, the lighting device turns on the fluorescent lamp 7. As described above, when the switch unit 5a of the time-off switch device 5 is manually operated before the human sensor 25 detects the human body, the main control unit 32 forcibly controls the fluorescent lamp 7 of the lighting fixture 6 for a certain period of time, for example. Turn on for 1 minute.

  When the human sensor 25 provided in the sensor device 2 of the parent device or the human sensor 25 provided in the sensor devices 3 and 4 of the child devices detects the presence of a human body, a human body detection signal is sent to the parent device. Is input to the slave unit / timed off switch communication I / F unit 28 of the illumination control device 26 arranged in the sensor device 2, and further from the slave unit / timed off switch communication I / F unit 28 to the main control unit 32. Entered.

  When a human body detection signal is input, the main control unit 32 outputs a control signal that causes the load control I / F unit 35 to turn on the relay 38 as a control signal corresponding to the presence of the human body. The load control I / F unit 35 turns on the relay 38 according to the control signal. When the relay 38 is turned on, an AC voltage from a commercial AC power source is applied between the load terminals 39 of the lighting control device 26, and the AC voltage is disposed in the lighting fixture 6 through the power line 9. Is input. Then, the lighting device turns on the fluorescent lamp 7. Thus, the main controller 32 turns on the fluorescent lamp 7 of the lighting fixture 6 when the human sensor 25 detects a human body. When the human sensor 25 detects the human body within a certain period during which the fluorescent lamp 7 of the lighting fixture 6 is forcibly turned on by manual operation of the switch unit 5a of the timed off switch device 5, the fluorescent lamp 7 Is lit continuously.

  The main control unit 32 then counts the first predetermined period T1 from the time when the human sensor 25 of the parent device sensor device 2 or the human sensor 25 of the child device sensor devices 3 and 4 detects the human body. To keep time. Then, the time measuring unit 34 sends a time measurement completion signal to the main control unit 32 when the time measurement of the first predetermined period T1 is up. When the time measurement completion signal is input, the main control unit 32 stops the control signal that turns on the relay 38 that is output to the load control I / F unit 35. The load control I / F unit 35 turns off the relay 38 by stopping the control signal. Thereby, the AC voltage from the commercial AC power supply is not applied between the load terminals 39, 39, the lighting device is not supplied with power, and the fluorescent lamp 7 is turned off.

  In addition, the main control unit 32 detects that the human sensor 25 detects the human body while the time measuring unit 34 is measuring the first predetermined period T1, and the human body detection signal is transmitted to the slave unit / timed off switch communication I. When input from the / F unit 28, the clocking by the clocking unit 34 is restarted. That is, the main controller 32 repeatedly causes the timer 34 to measure the first predetermined period T1 every time the human sensor 25 detects a human body.

  Then, as shown in FIG. 8A, the main control unit 32 detects the fluorescent lamp when the human sensor 25 does not detect the human body again within the first predetermined period T1 from the time when the human sensor 25 detects the human body. 7 is turned off.

  For example, when going out, the switch unit 5a of the timed off switch device 5 provided at the entrance is manually operated. Then, an external operation signal is input to the slave unit / timed off switch communication I / F unit 28 of the lighting control device 26, and further input from the slave unit / timed off switch communication I / F unit 28 to the main control unit 32.

  When the external control signal is input from the slave unit / timed off switch communication I / F unit 28 while the fluorescent lamp 7 is lit, the main control unit 32 turns on the relay 38 for the load control I / F unit 35. Stop the output of the control signal. By stopping the control signal, the load control I / F unit 35 turns off the relay 38. That is, when the switch unit 5a of the timed off switch device 5 is manually operated and an external operation signal is output from the timed off switch device 5, the fluorescent lamp 7 is forcibly turned off. And control of the fluorescent lamp 7 according to the detection signal by the human sensor 25 is stopped over the 2nd predetermined period T2 from the time of the said manual operation. That is, as shown in FIG. 8B, even when the human sensor 25 detects the human body and the detection signal is input to the main control unit 32 during the measurement of the second predetermined period T2, the main control unit 32 The fluorescent lamp 7 is forcibly turned off. And the main control part 32 cancels | releases stopping control of the fluorescent lamp 7 according to the detection signal by the human sensor 25 after 2nd predetermined period T2, and responds again to the detection signal by the human sensor 25. Thus, turning on / off of the fluorescent lamp 7 is controlled. Further, the main control unit 32 forces the fluorescent lamp 7 for a certain period when the switch unit 5a of the timed off switch device 5 is operated during the second predetermined period or before the human sensor 25 detects the human body. Light up.

  In FIG. 8, the automatic operation mode is that the main control unit 32 controls the turning on / off of the fluorescent lamp 7 in accordance with the detection signal of the human sensor 25, that is, the control by the sensor control means. It represents that. The timed off mode indicates that the main control unit 32 forcibly controls the fluorescent lamp 7 to be turned off in accordance with an external operation signal from the timed off switch device 5 (control by the external operation control means). Yes.

  As described above, before the human sensor 25 detects a human body, for example, when the switch unit 5a of the timed off switch device 5 provided at the entrance is manually operated, the fluorescent lamp 7 is lit for a certain period. Therefore, for example, it does not move in the dark, it is easy to move to the room where the fluorescent lamp 7 is lit, and the sense of discomfort is prevented by the fact that the fluorescent lamp 7 is lit when it reaches the room. Is done.

  Then, when the fluorescent lamp 7 is turned on according to the detection signal of the human sensor 25, the fluorescent lamp 7 is manually operated over the second predetermined period T2 by manually operating the switch unit 5a of the time-off switch device 5. 7 is forcibly turned off, so that wasteful power consumption due to the lighting of the fluorescent lamp 7 when no human body is present can be eliminated.

  The load control I / F unit 35 turns on the relay 38 when a control signal for turning on the relay 38 is output from the main control unit 32, and turns off the relay 38 by stopping the output of the control signal. However, the present invention is not limited to this, and when the pulse signal as the control signal corresponding to the presence of the human body is output from the main control unit 32, the relay 38 is turned on and the on state is maintained. When a pulse signal as a control signal corresponding to the absence of a human body is output from 32, the relay 38 may be held off and the relay 38 may be turned off.

  Further, the switch unit 5 a of the timed off switch device 5 may be divided for turning on and off the fluorescent lamp 7.
