It is characterized by prohibiting a corresponding lighting state.

In this configuration, when a control signal is received by the receiving unit of one lighting device, if there is a person within a predetermined area of the human detecting unit of the one lighting device, the detection result that there is a person by the human detecting unit When the presence of a person is detected or a predetermined time is being measured, the light source is in an illumination state according to the control signal. On the other hand, if there is no person, the light source is not in an illumination state according to the control signal. . Further, if there is no person in the predetermined area of the human detection means of another lighting device adjacent to the one lighting device, even if the receiving means of the other lighting device receives a control signal for the one lighting device, The light source of the illuminating device does not enter the illumination state according to the control signal. Thus, it is possible to prevent the lighting state of the light source of the lighting device from being changed by a control signal for another lighting device without assigning an individual address for each lighting device, and for a person to be at the lighting device. Although it is not, it can prevent that the illumination state of the light source of the illuminating device changes.

FIG. 1 is a configuration diagram of the illumination device according to the first embodiment of the present invention, FIG. 2 is a schematic diagram of the illumination device, and FIG. 3 is an operation explanatory diagram of the illumination device.

  As shown in FIG. 2, the lighting device according to the first embodiment is installed on a ceiling surface (not shown) and a commercial power source AC via a wall switch WS. And a lighting device body 2 as a lighting fixture to be connected.

  As shown in FIGS. 1 and 2, the remote control transmitter 1 includes a remote control operation unit 11 including a plurality of operation buttons 11a, a signal transmission unit 12 for transmitting a control signal as a wireless signal such as infrared rays, In addition to a power supply unit 13 configured by a battery (not shown) and the like for supplying driving power to each unit of the remote control transmitter 1, a remote control unit 10 is also provided.

  The remote control unit 10 is configured by, for example, a microcomputer, and in response to an operation input to the remote control operation unit 11, a command corresponding to the operation input is read from a memory built in the microcomputer, for example, and is transmitted via the signal transmission unit 12. Control for transmitting a control signal including a command as a wireless signal is executed. The commands include various commands such as lighting, dimming, and extinguishing.

  The illuminating device main body 2 includes a lighting load unit 21 including a light source such as a fluorescent lamp and a lighting circuit unit for turning on, adjusting, or turning off the light, and a signal for receiving a control signal from the remote control transmitter 1 as a wireless signal. There are a receiving unit 22, a human body sensor unit 23 for detecting whether or not there is a person in a predetermined area (a surrounding area R immediately below the lighting device main body 2 in the example of FIG. 2), and a human by the human body sensor part 23. And a power supply unit 26 that generates a power source (for example, a DC power source) from the commercial power source AC and supplies the power source 26 to each unit of the lighting apparatus body 2. And an instrument control unit 20. The timer unit 25 may be configured to time various predetermined times set by the appliance control unit 20.

  The appliance control unit 20 is configured by, for example, a microcomputer, and executes various processes such as control of the lighting device body 2 in general. For example, when the wall switch WS is turned on, a power source is generated by the power source unit 26, and when power is supplied from the power source and activated, the light source is controlled to turn on, for example, through the lighting circuit unit of the lighting load unit 21. Executed.

  After the activation, the detection result by the human body sensor unit 23 is constantly monitored, and when the detection result that there is a person is obtained from the human body sensor unit 23, the timer unit 25 performs a predetermined time every time the detection result is not obtained. Control for starting timing is executed. When the control signal is received by the signal receiving unit 22, the light source of the illumination load unit 21 is controlled when the human sensor unit 23 detects that there is a person or when the timer unit 25 is measuring a predetermined time. The lighting state (lighting state, dimming state, extinguishing state) according to the command included in the signal is set. Otherwise, the light source is prohibited from being set to the lighting state according to the command included in the control signal. Is executed.

  Next, the operation of the illumination device having the above configuration will be described with reference to FIG. For example, when the wall switch WS is turned on, a power source is generated by the power source unit 26, the appliance control unit 20 is activated upon receiving power supply from the power source, and turns on the light source through the lighting circuit unit of the lighting load unit 21. For example, a lighting (high brightness lighting) state is set (t1 in FIG. 3).

  Thereafter, when a detection result indicating that there is a person is obtained from the human body sensor unit 23 (t2), the timer unit 25 starts measuring the predetermined time T at a time point (t3) when the detection result is not obtained. When the control signal (control signal including a dimming command in the example of FIG. 3) is received by the signal receiving unit 22 (t4), the human body sensor unit 23 detects that there is a person or the timer unit 25. Since the predetermined time is being measured (in the figure, being timed), the appliance control unit 20 sets the light source to the illumination state (dimming state) according to the control signal through the lighting circuit unit of the illumination load unit 21. That is, the period from the time when the human body sensor unit 23 detects that there is a person to the time when the predetermined time is measured is the reception period for receiving the control signal from the remote control transmitter 1, and the period for shifting to the remote control mode.

  Thereafter, a detection result that there is a person is obtained from the human body sensor unit 23 (t5, t6), and the timer unit 25 starts measuring the predetermined time T every time the detection result is not obtained. Then, for some reason, the control signal is received by the signal receiving unit 22 after the time measurement end point (t7) of the predetermined time T (t8), but the light source may be brought into an illumination state according to the control signal. Since it is prohibited, the current lighting state is maintained.

  Here, when a control signal is received by the signal receiving unit 22 of one lighting device body 2 (left in the example of FIG. 2), a person is within a predetermined region R of the human body sensor unit 23 of the one lighting device body 2. If there is, a detection result that there is a person is obtained by the human body sensor unit 23, and when the presence of a person is detected or during the measurement of a predetermined time, the light source is in an illumination state according to the control signal, If there is no person, the light source will not be in an illumination state according to the control signal. Further, if there is no person in the predetermined region R of the human body sensor unit 23 of the other (right) lighting device body 2 adjacent to the one lighting device body 2, the signal reception unit 21 of the other lighting device body 2 is the same. Even if the control signal for the illumination device body 2 is received, the light sources of the other illumination device bodies 2 do not enter the illumination state according to the control signal.

  As described above, according to the first embodiment, it is possible to prevent the lighting state of the light source of the lighting device body 2 from being changed by a control signal for another lighting device body 2 without assigning an individual address to each lighting device. In addition, it is possible to prevent the illumination state of the light source of the illuminating device body 2 from changing even though there is no person at the illuminating device body 2.

  In the first embodiment, adjustment means (such as a movable mechanism) for adjusting the detection area (predetermined area) of the human body sensor unit 23 may be provided, or transmission by the signal transmission unit 12 of the remote control transmitter 1 is possible. You may make it provide the adjustment means for adjusting the range. According to this configuration, usability is further improved.

  The wireless signal is not limited to infrared rays, and may be radio waves that propagate to places outside the line of sight. In this case, measures such as assigning an identification code (ID) such as an address are not necessary.

(Embodiment 2)
FIG. 4 is a configuration diagram of the illumination device according to the second embodiment of the present invention, FIG. 5 is a schematic diagram of the illumination device, and FIG. 6 is an operation explanatory diagram of the illumination device.

  As shown in FIG. 4, the illumination device of the second embodiment receives (detects) a series of power-off / on by the wall switch WS as a control signal for the light source of the illumination load unit 21 as a difference from the first embodiment. The apparatus control unit 20 further includes a power cut-off detection unit 27 for using the control signal received by the power cut-off detection unit 27 in the same manner as the control signal received by the signal reception unit 22. To do.

  That is, when the control signal is received by the power cut-off detection unit 27, the appliance control unit 20 detects that there is a person by the human body sensor unit 23 or is measuring the predetermined time by the timer unit 25. While the light source of the unit 21 is set to an illumination state according to the control signal received by the power interruption detection unit 27, otherwise, the control for prohibiting the light source from being set to the illumination state according to the control signal is performed. Execute. In addition, each time the power interruption detection unit 27 receives a control signal, the appliance control unit 20 sequentially switches the control signal as dimming, bean ball, extinguishing, lighting, dimming, and so on. Shall be handled. Here, it is assumed that the power supply unit 26 can supply power to the appliance control unit 20 for at least a short time of a series of power off-on. The current control state for the light source of the illumination load unit 21 is stored in a readable / writable nonvolatile memory, and the control signal received by the power shutoff detection unit 27 based on the control state stored in the nonvolatile memory. As described above, the appliance control unit 20 may be configured so as to be sequentially switched and handled.

  Next, the operation of the illumination device having the above configuration will be described with reference to FIG. For example, when the wall switch WS is turned on (see FIG. 5A), a power source is generated by the power source unit 26, the appliance control unit 20 is activated by receiving power supply from the power source, and the lighting load unit 21 is activated. For example, the light source is turned on through the lighting circuit section (t1 in FIG. 6).

  Thereafter, when a detection result indicating that there is a person is obtained from the human body sensor unit 23 (t2), the timer unit 25 starts measuring the predetermined time T at a time point (t3) when the detection result is not obtained. Then, when a person turns off / on the wall switch WS in a short time and the control signal is received by the power cut-off detection unit 27 (t4), when the human sensor unit 23 detects that there is a person or a timer unit Since it is during the time measurement of the predetermined time by 25 (the time is being measured in the figure), the appliance control unit 20 sets the light source to the illumination state (dimming state) according to the control signal through the lighting circuit unit of the illumination load unit 21.

  Thereafter, when a detection result indicating that there is a person is obtained from the human body sensor unit 23 (t5), the timer unit 25 starts measuring the predetermined time T when the detection result is not obtained. When the control signal is received by the power shut-off detection unit 27 (t6), since the human sensor unit 23 detects that there is a person or the timer unit 25 is counting a predetermined time, the instrument control unit 20 The light source is brought into an illumination state (bean ball state) according to the control signal through the lighting circuit unit of the illumination load unit 21. Subsequently, when the control signal is received by the power cut-off detection unit 27 (t7), it is during the detection of the presence of a person by the human body sensor unit 23 or the measurement of the predetermined time by the timer unit 25. Through the lighting circuit part of the illumination load part 21, the light source is brought into an illumination state (light-off state) corresponding to the control signal.

  Here, even if an instantaneous power failure occurs due to a lightning strike or the like when the user is absent in this unlit state, even if a series of power off / on is detected by the power shutoff detection unit 27, there is a person by the human body sensor unit 23. At the time of detection or because the timer unit 25 is not measuring the predetermined time (FIG. 5B), it is prohibited to set the light source of the illumination load unit 21 to the illumination state corresponding to the power-off / on, and the current extinguishing state is Will be maintained. Thereby, useless electric power consumption by the light source of the illumination load part 21 lighting can be prevented.

  According to the second embodiment, the same effect as that of the first embodiment can be obtained, and the wall switch WS can be turned off / on without using the remote control transmitter 1 (even when lost or broken). The light source of the illumination load unit 21 can be switched to a desired illumination state.

  In the second embodiment, adjusting means (such as a movable mechanism) for adjusting the detection area (predetermined area) of the human body sensor unit 23 may be provided in accordance with the installation location of the wall switch WS. According to this configuration, usability is further improved.

It has a mode switching function for switching to a mode or forced extinguishing mode, and executes control according to the mode switched by this. That is, when the mode switching function is switched to the automatic lighting mode, if the human body sensor unit 23 detects that there is a person, the light source of the illumination load unit 21 is turned on, and the human body sensor unit 23 If a predetermined time has elapsed since the detection result indicating that there is a person can no longer be obtained, a control for turning off the light source of the illumination load unit 21 is executed. On the other hand, when the mode is switched to the forced-off mode by the mode switching function, the light source is turned off (if it is not turned off, the light is turned off, the light is turned off, regardless of the detection result that there is a person by the human body sensor unit 23). If so, control is performed to leave the light off.

  Next, the operation of the illumination device having the above configuration will be described with reference to FIG. For example, when the wall switch WS is turned on, a power source is generated by the power source unit 26, the appliance control unit 20 is activated upon receiving power supply from the power source, and turns on the light source through the lighting circuit unit of the lighting load unit 21. For example, the lighting state is set (t1 in FIG. 8).

  Thereafter, when a detection result indicating that there is a person is obtained from the human body sensor unit 23 (t2), the timer unit 25 starts measuring the predetermined time T at a time point (t3) when the detection result is not obtained. When the remote control transmitter 1 presses the “standby extinction” button and the signal reception unit 22 receives a control signal for switching to the automatic lighting mode (t4), there is a person from the human body sensor unit 23. Or when a predetermined time is being measured by the timer unit 25, the mode is switched to the automatic lighting mode.

  Thereafter, a detection result that there is a person by the human body sensor unit 23 is obtained, and when a predetermined time T has elapsed from the time when the detection result is no longer obtained (t5), the appliance control unit 20 uses the light source of the illumination load unit 21. Is turned off.

  Thereafter, when a detection result that there is a person by the human body sensor unit 23 is obtained (t6), the appliance control unit 20 turns on the light source of the illumination load unit 21. When the “forced extinction” button is pressed by the remote control transmitter 1 and the control signal for switching to the compulsory extinction mode is received by the signal receiving unit 22 (t7), there is a person by the human body sensor unit 23. Or when the timer unit 25 is measuring a predetermined time, the forced control mode is switched to the appliance control unit 20 and the light source of the illumination load unit 21 is turned off. Thereafter, even if the human body sensor unit 23 obtains a detection result that there is a person (t8), the light source is turned off regardless of the detection result.

Various buttons for transmitting control signals are provided.

  Then, as a difference from the first embodiment, the appliance control unit 20 receives the control signal for switching to the dark automatic lighting mode, the continuous lighting mode, or the security mode when the signal receiving unit 22 receives the control signal. Accordingly, a mode switching function for switching to a dark automatic lighting mode, a continuous lighting mode, or a crime prevention mode is provided, and control is executed according to the mode switched by this.

  That is, when the mode switching function is used to switch to the dark automatic lighting mode, when the detection result that there is a person by the human body sensor unit 23 is obtained, the detection result of the ambient illuminance by the illuminance sensor unit 24 is the predetermined illuminance. If the illumination intensity is lower than that, the light source of the illumination load unit 21 is turned on. If the illumination intensity is not lower, control for prohibiting the light source from being turned on is executed. When the light source is prohibited from being turned on, the light source remains in the state (light control or extinguishing state) when the human body sensor unit 23 cannot detect the presence of a person.

  When the mode is switched to the continuous lighting mode by the mode switching function, the light source of the illumination load unit 21 is turned on (if the lighting is not on, the lighting state is turned on) regardless of the detection result that there is a person by the human body sensor unit 23. If it is in the lit state, the control is performed to keep the lit state).

  When the crime prevention mode is switched by the mode switching function, when the human body sensor unit 23 obtains a detection result that there is a person, the light source of the illumination load unit 21 from the time point when the timer unit 25 finishes measuring a predetermined time. The control to make the blinking state is executed.

  Next, the operation of the illumination device having the above configuration will be described. When the detection result that there is a person is obtained from the human body sensor unit 23 after activation of the appliance control unit 20, the timer unit 25 starts measuring the predetermined time T when the detection result is not obtained. Then, the remote control transmitter 1 pushes the button of the dark automatic lighting mode, the continuous lighting mode or the crime prevention mode, and the signal receiving unit 22 is used for switching to the dark automatic lighting mode, the continuous lighting mode or the crime prevention mode. When the control signal is received, if the human body sensor unit 23 detects that there is a person or if the timer unit 25 is measuring a predetermined time, it switches to the dark automatic lighting mode, the continuous lighting mode, or the crime prevention mode.

  When switching to the automatic lighting mode in the dark, when the detection result that there is a person by the human body sensor unit 23 is obtained, if the detection result of the ambient illuminance by the illuminance sensor unit 24 is lower than the predetermined illuminance, the appliance control The unit 20 turns on the light source of the illumination load unit 21. On the other hand, since the light source is prohibited from being turned on unless the illumination is low, the light source is in a state when a detection result indicating that there is a person by the human body sensor unit 23 cannot be obtained (dimming or extinguishing state). Will remain.

  When the mode is switched to the continuous lighting mode, the appliance control unit 20 turns on the light source of the illumination load unit 21 regardless of the detection result that there is a person by the human body sensor unit 23.

  When switching to the crime prevention mode, when the detection result that there is a person by the human body sensor unit 23 is obtained, the appliance control unit 20 blinks the light source of the illumination load unit 21 from the time point when the timer unit 25 finishes counting a predetermined time. Put it in a state.

  According to the fourth embodiment, the individual lighting device main body 2 is set to the automatic lighting mode in the dark mode, the continuous lighting mode, or the crime prevention mode by the remote control transmitter 1 without assigning an individual address for each lighting device. (See FIG. 10).

  In the case of the automatic lighting mode in the dark, if the ambient illuminance is low when a person comes to the lighting device, the light source is turned on, for example, the light source of the lighting device is turned off at night. Even if it is dark in the state, there is no need to search for the wall switch SW, the remote control transmitter 1 and the like for lighting the lighting device, and the lighting operation is not necessary and the convenience is improved. In addition, if the detection result of the ambient illuminance by the illuminance sensor unit 24 is not lower than the predetermined illuminance, the light source is not automatically turned on, so that an energy saving effect is obtained.

  Further, if the user switches to the crime prevention mode when going out, the human body sensor unit 23 obtains a detection result that there is a person continuously or intermittently, and the timer unit 25 counts a predetermined time based on the detection result. When the time measurement ends, the light source blinks, so that the intruder who is away can appear to have operated the security system.

  In the third and fourth embodiments, the timer unit 25 starts measuring the predetermined time and the second predetermined time based on the detection result that there is a person by the human body sensor unit 23, so that the appliance of the lighting device body 2 The control unit 20 may allow the mode switching function to switch the mode when the human body sensor unit 23 detects that there is a person or when the timer unit 25 is measuring the second predetermined time. .

  In each of the above embodiments, the remote control transmitter 1 is configured to transmit a control signal by a wireless signal such as infrared rays. However, the control signal is transmitted by an ultrasonic wave or a radio wave propagating to a non-line-of-sight range. The structure to do may be sufficient.

  In addition, a display means is provided in the vicinity of the signal receiving unit 22, for example, when the human sensor unit 23 detects that there is a person or during the measurement of a predetermined time by the timer unit 25, the display of the display means (for example, lighting or LED lighting) It may be configured to notify that the control signal can be received by blinking). According to this configuration, it is possible to provide a device that is easy for the user to understand. Further, by providing the display means in the vicinity of the signal receiving unit 22, the position of the signal receiving unit 22 to which the remote control transmitter 1 should be directed is easily understood.

  Further, the power supply unit 26 has a function of executing or stopping power supply to at least the signal receiving unit 22, and at least during the detection of a person by the human body sensor unit 23 or during the measurement of a predetermined time by the timer unit 25, A configuration in which power is supplied to the receiving unit 22 may be used. According to this configuration, power supply to the signal receiving unit 22 is not executed unless at least the human body sensor unit 23 detects that there is a person or the timer unit 25 is measuring a predetermined time, thereby reducing power consumption. can do.

  Further, the lighting device main body 2 includes an interlocking lighting device that includes a light source and is installed at a location different from the lighting device main body 2. The lighting device main body 2 has an interlocking output unit. If the detection result is obtained, an interlocking signal for making the lighting state similar to the lighting state of its own light source is output from the interlocking output unit to the interlocking lighting fixture. It is also possible to adopt a configuration in which the own light source is brought into an illumination state in accordance with the interlock signal from the illumination device body 2 received by the interlock input unit.
