  Therefore, when the remote controller is turned off, the light source can be turned on when the power is turned on after turning off the power with the wall switch. However, if this is done, for example, when the power is cut off due to a power failure, when the power returns, it will be in the same state as when the power was turned on after the power was turned off. The light source that should have been turned on turns on. In particular, if a power outage occurs when the user is absent, the state where the light source remains on continues, which is not preferable.

  Hereinafter, the present invention will be described with reference to the drawings illustrating embodiments thereof. FIG. 1 is an explanatory diagram illustrating an installation example of the lighting device 100 according to the present embodiment, and FIG. 2 is a block diagram illustrating an example of a configuration of the lighting device 100 according to the present embodiment. FIG. 1A shows a configuration in which a wall switch 2 (hereinafter also referred to as “wall SW 2”) as a power on / off switch is interposed between the lighting device 100 and the commercial power source 1. Indicates. FIG. 1B shows an installation example in which the wall switch 2 (hereinafter also referred to as “wall SW2”) is not interposed between the lighting device 100 and the commercial power source 1 and a so-called wall SW is not provided. Lighting device 100 of the present embodiment can detect the presence or absence of wall SW2.

  As illustrated in FIG. 2, the lighting device 100 includes a fuse 11, a rectifier circuit 12, a switching circuit 13, a constant current circuit 14, a PWM control circuit 15, for example, a light source unit 16 including an LED, and a power application detection circuit 17. A control microcomputer 18, a light receiving unit 19, a memory 20, and the like. In addition, the light source part 16 is not limited to LED.

  The fuse 11 is for interrupting an overcurrent of a predetermined value or more in order to protect the lighting device 100 when an abnormality such as a short circuit occurs in the lighting device 100. The rectifier circuit 12 performs full-wave rectification on the AC 100V and converts it into direct current.

  The switching circuit 13 is composed of, for example, a transistor or an FET, and is switched to a predetermined voltage value by performing a switching operation at a predetermined frequency (for example, an operation for alternately turning on / off a pair of transistors). Output voltage.

  The constant current circuit 14 includes a rectifier circuit, a transistor, an operational amplifier, and the like, and converts the alternating voltage supplied from the switching circuit 13 into a DC voltage (for example, 33 V) and controls the output current to be constant.

  The PWM control circuit 15 functions as a light source drive unit, and controls the current supplied to the light source unit 16 by performing pulse width modulation on the DC voltage output from the constant current circuit 14. More specifically, the control microcomputer 18 outputs a control signal corresponding to the lighting (full lighting, 100% dimming), extinguishing, and dimming level of the light source unit 16 to the PWM control circuit 15. Performs lighting (full lighting, 100% dimming), extinguishing, and dimming control of the light source unit 16 based on the acquired control signal.

  The power supply detection circuit 17 has a function as a power supply detection unit, detects the presence / absence of AC100V supplied to the lighting device 100 (whether power is applied), and outputs the detection result to the control microcomputer 18.

  The light receiving unit 19 receives infrared rays from a remote control (not shown) as a remote controller operated by a user (hereinafter also referred to as “remote control”), extracts a signal transmitted from the remote control, and extracts the extracted signal. Output to the control microcomputer 18. The signal transmitted from the remote controller is, for example, for turning on, turning off, dimming, and toning the light source.

  The memory 20 stores data necessary for the control microcomputer 18 to perform predetermined processing, and also stores processing results and the like. The memory 20 stores one of two modes of the lighting device 100 so as to be selectable. Here, the two modes are a presence mode (present information) and a no mode (no information) indicating presence / absence of the wall SW2 (power on / off switch), respectively. That is, a mode with a wall (with wall SW mode) indicates that the wall SW2 is provided, and a mode without (with no wall SW mode) indicates that the wall SW2 is not provided. In the present embodiment, the presence information is also called a presence mode, and the absence information is also called a no mode.

  The control microcomputer 18 has a timer function, and starts the timer count when the power supply detection circuit 17 detects the presence of power supply (AC100V). The control microcomputer 18 stops the timer count when the power application detection circuit 17 detects the presence of power supply (AC100V) and then detects the absence of power supply (AC100V), and the timer count time (power supply) Application time) is calculated.

  Further, the control microcomputer 18 has a function as a setting unit for setting the wall SW presence mode (present mode) or the wall SW no mode (no mode).

  FIG. 3 is a time chart showing a first embodiment for setting the wall SW presence mode and the non-mode. As shown in FIG. 3A, in the control microcomputer 18, the time T (elapsed time from the detection time t0) counted from the detection time t0 when the power application detection circuit 17 detects the presence of power supply is a predetermined first threshold value T1. If the state with power supply continues until, the wall SW no mode (no information) is set. The first threshold T1 can be set to 24 hours, for example. That is, when the lighting is installed in the place where the wall SW2 is provided, it is considered that the power on / off operation of the lighting device 100 is performed on the wall SW2 at least once within the day when the lighting is installed. Therefore, when the time T from when the power is applied to when the power is turned off is longer than the first threshold T1, it can be determined that the wall SW2 is not provided, and the mode is set to no mode. For example, when the lighting device 100 is turned off with the remote control and the mode is set to no mode, even if the power is turned off, it is not an operation by the wall SW2, but an unintended power cut due to a power failure. It is possible to prevent unintended lighting by maintaining the light source unit 16 in the extinguished state.

  Further, as shown in FIG. 3B, the control microcomputer 18 sets the wall SW presence mode (present information) when the power supply detection circuit 17 detects the presence of power supply after detecting the power supply application at time t0. To do. When the power is turned off after the power is applied, it can be determined that the wall SW2 is provided, and the presence mode is set. And, for example, when the mode is set to ON, if the power is turned off when the lighting device 100 is turned off by the remote controller, it is assumed that this is an operation by the wall SW2, and the light source unit 16 is turned on, Lighting, extinguishing, wall dimming, and wall toning by the wall SW2 are possible.

  In FIG. 3, the time t0 when the power is applied is, for example, the time when the lighting device 100 shipped from the factory is installed at the installation location and the power line from the commercial power source 1 is connected to the power terminal (not shown). Can be assumed. In the present embodiment, the time T is set to 24 hours. However, the time T is only an example and is not limited to this. The time T may be 1 hour or 2 hours. In this embodiment, when an instantaneous power failure occurs during power application, the power is turned off and on, and it is determined that the wall SW is present even when there is no wall SW2. Therefore, for example, by determining that the power-off period of 100 msec is an instantaneous power failure, the mode state can be kept unchanged.

  Next, mode setting when determining whether or not to apply power after the lighting device 100 is once installed will be described. FIG. 4 is a time chart showing a second embodiment of the setting of the wall SW presence mode and the non-mode. FIG. 4 shows the first power-on and the second power-on. Then, as shown in FIG. 4, it is assumed that the control microcomputer 18 is set to the wall SW presence mode by the first power-on.

  For example, when the presence mode is set when the lighting apparatus 100 is shipped from the factory, the control microcomputer 18 further sets the second state in which power is applied by the power application detection circuit 17 (time t3 in FIG. 4). When a time longer than the threshold value T2 (> first threshold value T1) is detected, no mode is set.

  As shown in FIG. 4, when the lighting device 100 is installed, if power is applied and then no power is applied, even if the wall SW presence mode is erroneously set, the subsequent power supply is applied. When the time T counted from the time point t3 (the elapsed time from the time point t3) is longer than the second threshold value T2 (> first threshold value T1), the wall SW non-mode can be set.

  As a result, even if the mode is erroneously set, the mode can be correctly set to no mode. In addition, by setting the second threshold T2 longer than the first threshold T1, for example, the absence of the user who has installed the lighting device in the room with the wall SW2 continues, and the power is not turned off for a predetermined period. Accordingly, it is possible to suppress the case where the wall SW 2 mode is set despite the presence of the wall SW 2. Even when the lighting device is moved from the room with the wall SW2 to the room without the wall SW2, the wall SW no-mode can be set by applying no power during the second threshold T2.

  FIG. 5 is a time chart showing a third embodiment for setting the wall SW presence mode. As shown in FIG. 5A, the control microcomputer 18 sets the wall SW presence mode when the power supply detection circuit 17 detects a wall dimming operation within a predetermined time. The wall dimming operation is, for example, an operation of turning on / off the wall SW2 from the state in which the wall SW2 is turned off, or an operation of turning on / off the wall SW2 from the state in which the wall SW2 is turned on. In the example of FIG. 5A, the power supply is not applied for a time Δt from the power supply applied state, and then the power supply is applied. That is, when the time Δt from when the power supply is applied to when the power supply is applied and when the power supply is applied again is within a predetermined time, the wall SW presence mode is set. The predetermined time can be, for example, 2 seconds, but is not limited thereto.

  As shown in FIG. 5B, when the power supply detection circuit 17 detects a wall dimming operation within a predetermined time, the control microcomputer 18 sets the wall SW presence mode. In the example of FIG. 5B, the power supply is applied only for the time Δt from the state where no power is applied, and then the state where no power is applied. That is, when the time Δt from when no power supply is applied to when the power supply is applied and when the power supply is turned off again is within a predetermined time, the wall SW presence mode is set. The predetermined time is the same as in the case of FIG. 5A.

  For example, it is assumed that the lighting device 100 is installed in a place where the wall SW2 is not provided and the non-mode is set. When the lighting device 100 is moved to a place where the wall SW2 is located, the wall dimming operation, that is, the operation of turning the wall SW2 off or on, or the operation of turning the wall SW2 on or off is short (for example, 2 seconds). The mode can be easily changed to the presence mode only by performing in.

  In the present embodiment, the detection of the wall dimming operation includes, for example, the case where the wall SW2 is turned off / on only once, and the turning-on / off operation is continued twice or more. Including the case where it is performed. Similarly, for example, it includes not only the case where the wall SW2 is turned on / off only once, but also the case where the wall SW2 is turned on / off continuously twice or more.

  The lighting device 100 can set (initialize) the wall SW non-mode as an initial state at the time of factory shipment. Since the wall SW no-mode is initialized, unintentional lighting is prevented by maintaining the state of the light source (for example, the light-off state) assuming that the power supply is unintentionally turned off due to a power failure even if the power is turned off. be able to.

  Next, the relationship between the two modes and the lighting control will be described. FIG. 6 is an explanatory diagram showing an example of the relationship between the two modes and the lighting control. As shown in FIG. 6, when the remote control is turned off and the power supply is changed from no application, that is, the light receiving unit 19 receives a signal requesting the light source unit 16 to be turned off. When it is detected from the absence of power supply to the presence of power supply and the wall SW presence mode is set, the control microcomputer 18 controls the PWM control circuit 15 to turn on the light source unit 16. Accordingly, when the wall SW2 is provided, the light source can be turned on / off by the on / off operation of the wall SW2.

  Further, when the remote control is turned off and the power supply is changed from being not applied to being present, that is, the light receiving unit 19 has received a signal requesting the light source unit 16 to be turned off, and the power application detection circuit 17 does not apply power. When the presence of power supply is detected and the wall SW no mode is set, the control microcomputer 18 controls the PWM control circuit 15 to keep the light source unit 16 off. Thereby, even when using the illuminating device 100 in the location where wall SW2 is not installed, the unintentional lighting by a power failure can be prevented.

  When the wall SW presence mode is set, the control microcomputer 18 makes wall SW dimming effective, for example, executes wall SW dimming to change the dimming.

  Here, the wall SW dimming is performed after the operation of turning off the power for a predetermined time (for example, within 2 seconds) within 10 seconds from the time when the power is turned on by operating the wall SW2. In such a case, the lighting state of the lighting device 100 is switched according to a predetermined order. For example, all lights (100%), 75% dimming, 50% dimming, 25% dimming, extinguishing, all lights (100%). Further, in the case of a lighting device having a color adjustment function, it is possible to set all lights (cold color), all lights (warm color), nightlight, off, all lights. Thereby, when wall SW2 is installed, wall SW dimming can be performed.

  The predetermined time (for example, 2 seconds) is the same between the case where the wall SW2 mode is set by operating the wall SW2 and the case where the lighting state of the light source (full lighting, extinguishing, dimming state) is switched. The predetermined time may be different. For example, when the predetermined time is the same, the wall SW2 mode is set by repeating ON / OFF operation of the wall SW2 in sequence, all lamps (100%), 75% dimming, 50% dimming, 25% Dimming, light extinction, and all lights (100%) can be shifted. In addition, once the wall SW presence mode is set, the wall SW2 is sequentially turned on and off, for example, all lamps (100%), 75% dimming, 50% dimming, 25% dimming. , Extinguishment, all lights (100%).

  When the wall SW non-mode is set, the control microcomputer 18 disables the wall SW dimming, shifts to the wall SW presence mode, and does not perform the wall SW dimming.

  FIG. 7 is a flowchart showing an example of a process procedure for mode setting when the wall SW no-mode at the time of installation of the lighting apparatus 100 of the present embodiment is initially set. The control microcomputer 18 has set the wall SW non-mode (S11), detects the application of power (S12), and starts the timer count (S13).

  The control microcomputer 18 determines whether or not power is applied (S14). If power is applied (YES in S14), the control microcomputer 18 determines whether or not the power application time T is longer than the first threshold T1 (S15). ). When the power supply application time T is shorter than the first threshold T1 (NO in S15), the control microcomputer 18 continues the processing from step S14.

  When the power application time T is longer than the first threshold T1 (YES in S15), the control microcomputer 18 maintains the wall SW non-mode (S16) and ends the process. When the power is not applied (NO in S14), the control microcomputer 18 sets the wall SW presence mode (S17) and ends the process.

  FIG. 8 is a flowchart showing an example of a process procedure for mode setting when the mode regarding the wall SW2 at the time of installation of the lighting apparatus 100 of the present embodiment is not initially set. The example of FIG. 8 shows processing when the mode relating to the wall SW2 is not set to the no mode or the presence mode.

  The control microcomputer 18 detects power supply application (S21), and starts a timer count (S22). The control microcomputer 18 determines whether or not power is applied (S23). If power is applied (YES in S23), it is determined whether or not the power application time T is longer than the first threshold T1 (S24). ).

  When the power application time T is shorter than the first threshold value T1 (NO in S24), the control microcomputer 18 continues the processing from step S23. If the power application time T is longer than the first threshold T1 (YES in S24), the control microcomputer 18 sets the wall SW non-mode (S25), and ends the process. When the power is not applied (NO in S23), the control microcomputer 18 sets the wall SW presence mode (S26) and ends the process.

  FIG. 9 is a flowchart illustrating an example of a processing procedure for mode setting at the time of power-on for the second and subsequent times when the wall SW no-mode is set for the lighting apparatus 100 of the present embodiment. In the example of FIG. 9, the wall SW no-mode is already set. The control microcomputer 18 detects application of power (S31) and turns on the timer.

  The control microcomputer 18 determines whether there is wall dimming (S32). Here, “with wall dimming” refers to, for example, determining whether or not a wall dimming operation has been performed.

  If there is no wall light control (NO in S32), the control microcomputer 18 continues the process of step S32. If there is wall dimming (YES in S32), the control microcomputer 18 sets the wall SW presence mode (S33) and ends the process.

  FIG. 10 is a flowchart illustrating an example of a processing procedure for mode setting at power-on for the second and subsequent times when the wall SW presence mode of the lighting apparatus 100 of the present embodiment is set. In the example of FIG. 10, the wall SW presence mode has already been set. The control microcomputer 18 detects application of power (S41) and starts timer counting (S42).

  The control microcomputer 18 determines whether there is wall dimming (S43). When there is no wall light control (NO in S43), the control microcomputer 18 determines whether or not the power application time T is longer than the second threshold T2 (S44), and the power application time T is greater than the second threshold T2. If it is short (NO in S44), the processing after step S43 is repeated.

  When the power application time T is longer than the second threshold value T2 (YES in S44), the control microcomputer 18 sets the wall SW non-mode (S45) and ends the process. If wall dimming is present (YES in S43), the control microcomputer 18 resets the timer (S46), and continues the processing from step S42.

  As described above, according to lighting device 100 of the present embodiment, the presence / absence of wall SW2 can be detected. Therefore, when there is no wall SW2, unintentional lighting due to a power failure can be prevented. When the wall SW2 is present, the wall SW2 can be turned on, turned off, and dimmed when it is desired to perform lighting, extinguishing, and dimming operations. In addition, when the lighting device 100 is moved to another location, even if the presence / absence of the wall SW2 changes, the presence / absence of the wall SW2 can be detected, and the situation after the transfer can be dealt with. Even if the wall SW no-mode is set once, it can be returned to or changed to the wall SW presence mode by operating the wall SW2.

  As described above, the illumination device according to the present invention detects the presence / absence of the power on / off switch (2) and the setting unit (18) for setting the presence / absence of information and the presence / absence of power application. A power source detection unit (17), and the setting unit sets no information when an elapsed time from a detection time point when power is applied by the power source detection unit is longer than a predetermined first threshold value. It is characterized by.

  In the present invention, the setting unit (18) sets the presence information and the absence information indicating the presence / absence of the power on / off switch (2). Note that the presence information is also referred to as a presence mode, and the absence information is also referred to as a non-mode. In other words, the setting unit sets two modes, a presence mode and a non-mode. The power on / off switch is not a switch provided in the lighting device main body, but is a wall SW (wall switch) provided on a wall or the like, for example. By operating the wall SW, the power on / off operation can be performed. It can be carried out. That is, the mode with the wall SW (the mode with the wall SW) indicates that the wall SW is provided, and the mode without the mode (the mode without the wall SW) indicates that the wall SW is not provided. The power source detection unit (17) detects the presence or absence of power application. That is, the power source detection unit detects whether or not a power source (for example, a commercial power source) is applied to the lighting device.

  Then, the setting unit sets the non-mode (no information) when the elapsed time T from the detection time point when the power supply is applied is longer than the predetermined first threshold value T1. The first threshold T1 can be set to 24 hours, for example. That is, when the wall SW is provided, it is considered that the lighting device is turned on and off at least once a day by the wall SW. In the case where it is longer than the first threshold value T1, no mode is set on the assumption that the wall SW is not provided. And when it is set to no-mode, unintentional lighting is prevented by maintaining the state of the light source (for example, the extinguishing state) assuming that the power source is unintended due to a power failure even if the power source is cut off. be able to.

  The illuminating device according to the present invention is characterized in that the setting unit (18) sets presence information when a wall dimming operation is detected by the power source detection unit (17).

  In the present invention, the setting unit (18) sets the present mode (present information) when the wall light control operation is detected by the power source detection unit (17). The wall dimming operation is, for example, an operation of turning on / off the wall SW or an operation of turning on / off the wall SW. For example, it is assumed that the illumination device is installed in a place where there is no wall SW and the non-mode is set. When the lighting device is moved to a place where the wall SW is located, the mode can be easily changed to the presence mode simply by performing the operation of turning on / off the wall SW or the operation of turning on / off the wall SW.

  In the illuminating device according to the present invention, when the setting unit (18) sets the presence information, the power supply detection unit (17) further sets the power supply application state longer than the second threshold value, which is longer than the first threshold value. When time is detected, no information is set.

  In the present invention, when the setting mode (18) is set, the setting unit (18) further detects a state in which power is applied by the power detection unit (17) for a time longer than the second threshold (> first threshold). When no, set no mode (no information). For example, when the lighting device is installed for the first time after shipment from the factory, power is applied and then the power is not applied. In the case where the time T until disappearance is longer than the second threshold value T2 (> first threshold value T1), no mode is set. Thereby, even if the presence mode is set by mistake, it can be correctly set to no mode. In addition, by setting the second threshold value to be longer than the first threshold value, it is possible to suppress erroneously setting the effective mode again.

  The lighting device according to the present invention is characterized in that the setting section (18) is initially set to no information.

  In the present invention, the setting unit (18) is initially set to no mode. The initial setting is, for example, a setting at the time of factory shipment of the lighting device. Since it is initially set to no-mode, it is possible to prevent unintentional lighting by maintaining the light source state (for example, the light-off state) as an unintended power-off due to a power failure even if the power is turned off. it can.

  The illumination device according to the present invention receives a light source (16), a receiver (19) that receives a signal requesting to turn off the light source from a remote controller, and a signal that requests the light source to be turned off by the receiver. When the presence of power application is detected by the power detection unit (17) and the presence information is set by the setting unit (18), the light source is turned on and the setting unit does not When information is set, a light source driving unit (15) for turning off the light source is provided.

  In the present invention, when the light source driving unit (15) receives a signal requesting the light source to be turned off by the receiving unit (19) and the power source detecting unit (17) detects the presence of power supply, When the presence mode is set in the setting unit (18), the light source (16) is turned on. Thereby, when the wall SW is provided, the light source can be turned on / off by the on / off operation of the wall SW. Further, the drive unit receives a signal requesting the light source to be turned off at the reception unit, and when the power supply detection unit detects the presence of power application, when the no-mode is set by the setting unit, the drive unit is turned on. Turn off. Thereby, even when using an illuminating device in the location where wall SW is not installed, the unintended lighting by a power failure can be prevented.
