BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control device for lighting.

0002

2. Description of the Related Art Conventionally, remote control devices are known in which illumination conditions are selected using a transmitter that emits infrared rays or the like. In addition, the technology for changing the lighting state of lighting equipment in the wall switch system from the first lighting state to the second lighting state including the off state by shutting off the wall switch in the room within a predetermined period of time was developed As shown in Japanese Patent No. 7277, there has been a conventional method.

Furthermore, the state of the load can be selectively controlled by remote control, and even if a transmitter for remote control is not found, the load can be brought into operation by cutting off the power supply within a predetermined time using a wall switch or the like. If the previous state was the operating state of the load, there are some devices that allow the load to be activated immediately by simply turning on the power again using a wall switch or the like.

0004

[Problem to be Solved] By the way, in the case of a remote control device in which the illumination state is selected by a transmitter that emits infrared rays, etc., the lighting condition may be affected depending on the lighting device itself, if the lighting device itself is not equipped with a switch for turning on the light. There was an inconvenience that the lights could not be turned on without a transmitter, which could easily be lost.

That is, for example, if you use a transmitter to turn off a lighting fixture when you go out, and then turn it on when you return home, you must find the transmitter in a pitch-black room.
As is well known, this is very inconvenient. Furthermore, even if the wall switch in the room is turned on again, the light remains off, so there is the inconvenience of having to find the transmitter and then operate the transmitter to turn it on.

Next, the device described in Japanese Patent Publication No. 56-7277 had the inconvenience of being unable to turn on the light without going to the wall switch. Furthermore, it is possible to selectively control the state of the load by remote control, and to return the load to the state before cutting off by cutting off the power supply for a predetermined time using a wall switch or the like without using a remote control transmitter, for example. If the load was in an inoperable state before being cut off, there is an inconvenience that the load cannot be activated immediately even if the power is turned on again using a wall switch.

The present invention has been made in view of the above-mentioned problems, and an object of the invention as claimed in claim 1 is to make it possible to turn on a lighting load using a wall switch or the like even without a transmitter. To provide a remote control device for lighting which can prevent the lighting load from being turned on when no one is present by putting the lighting load in an inoperable state when the power is restored after a power outage that is longer than a predetermined time.

In addition to the object of the invention set forth in claim 1, the object of the invention set forth in claim 2 is to prevent the operating state of the lighting load from being changed inadvertently even if a momentary power outage or the like occurs. An object of the present invention is to provide a remote control device for lighting. Furthermore, the object of the invention as set forth in claim 3 is to selectively control the lighting load by manually cutting off and applying power by manipulating a wall switch or the like, in addition to the object of the invention as set forth in claim 1. An object of the present invention is to provide a remote control device for lighting that is capable of blinking and switching to other auxiliary loads.

[0009]

Means for Solving the Problems In order to achieve the above-mentioned object, the invention according to claim 1 includes a lighting load and a remote control signal that is activated or inactivated by receiving a remote control signal in a receiving section. A reception control circuit has a load state selection circuit that selectively controls the load state, a power cutoff detection circuit that detects power cutoff, and a power cutoff detection circuit that determines the output time of the power cutoff detection signal of the power cutoff detection circuit, and At least a circuit that selectively controls the lighting load to be in an active state when the operating mode is a predetermined time and the operating mode, and initializes the lighting load to an inactive state if the output time is outside the predetermined time. It is.

[0010] Furthermore, the invention according to claim 2 is the invention according to claim 1, in which the lighting load is self-maintained in the state before the power is cut off if the output time is within a second predetermined time period that is shorter than the predetermined time period. It is equipped with self-holding means. Furthermore, the invention according to claim 3 is the invention according to claim 1, wherein the predetermined time and the operation mode are set by performing an arbitrary artificial operation of cutting off the application of the power supply voltage in a power outage state.

[0011]

[Operation]According to the invention as claimed in claim 1, the lighting load can be selectively controlled to be in operation simply by turning off the power supply according to the predetermined operating time and operating mode using a wall switch or the like. , the lighting load can be turned on even if the remote control transmitter is not found, and the lighting load is initialized to an inactive state when the power is restored after a power outage for a predetermined period of time or more. It is safe because the lighting load does not turn on inadvertently when no one is present.

[0012] Furthermore, in the invention as claimed in claim 2, when the power supply is cut off within the second predetermined time period which is shorter than the predetermined time period, if a self-holding means is provided to self-hold the lighting load in the state before the cutoff, instantaneous power outage etc. can be prevented. The state of the lighting load will not change inadvertently even if it happens. Furthermore, in the invention as claimed in claim 3, by artificially interrupting the application of power supply voltage during a power outage state to a predetermined operating time and operating mode, the user can turn on the wall switch with the intention of turning on the lighting load. The lighting load can be turned on only when the user operates the , which eliminates the possibility of accidentally turning on the lighting load.

[0013]

[Examples] The present invention will be explained below with reference to Examples. FIG. 1 is a circuit diagram according to this embodiment, in which a lighting load consisting of a lamp L and a small bulb M is connected to a power source AC via a wall switch 1 in a room and relay contacts RY1 and RY2. A receiving control circuit 2 surrounded by a dotted line in the lower half of the figure is controlled by a transmitter (not shown) that transmits a remote control signal RC such as infrared rays. The remote control signal RC from the transmitter is received by the receiving section 21 in the receiving control circuit 2,
A subsequent load state selection circuit 22 selectively controls the lighting load to be activated or deactivated.

The output of the receiving section 21 is sent to the load state selection circuit 22.
It is applied as a remote control signal input to the terminal SIG of the control section 23 consisting of an IC inside. Although the functions of the control unit 23 will be described later, the transistor Q2, the relay RY1, the transistor Q3, and the relay RY2 are each controlled by the control signals generated at the outputs P1 and P2, and the opening and closing of the corresponding relay contacts ry1 and ry2 are controlled. As a result, the opening and closing of the lamp L and the miniature bulb M are controlled.

Next, the DC power supply circuit that supplies DC power to the reception control circuit 2 will be explained with reference to the upper half of the figure. After being full-wave rectified and smoothed by a capacitor C2 via a diode D2, the voltage is made constant by a DC power supply section 3 consisting of a constant voltage circuit surrounded by a dotted line. And the smoothed voltage VB of the capacitor C2 is the transistor Q
The output voltage VC of the DC power supply section 3 is supplied to circuits other than the above-mentioned relay circuit in the reception control circuit 2.

Next, the power cutoff detection circuit 4 that detects cutoff of the power supply AC uses the rectified pulsating voltage of the rectifier BR before entering the diode D2, and transmits it to the resistors R1 and R2 via the diode D1. An example of series connection in a series circuit is shown. The divided voltage of resistors R1 and R2 is determined by the control unit 2.
It is connected to the set input SET of 3. Next, the operation of this embodiment will be explained with reference to FIGS. 2 and 3 as well.

Now, the wall switch 1 is turned on at time t1 as shown in FIG. 3(a), and then the remote control signal RC from a transmitter (not shown) is controlled as shown in FIG. 3(b). When the terminal SIG of the control section 23 is input, the code determination means 6 determines the code of the remote control signal RC via the input means 5 of the control section 23, and this remote control signal RC is a signal for lighting the lamp L. and the output state forming means (in this example, it is a latch type that holds the output state) 7 is latched to a predetermined state, and the output P1 is set to L level through the output means 8 as shown in FIG. 3(g). P2 sends out a control signal at H level as shown in FIG. 3(h). These signals are transmitted through transistor Q2,
Connect relays RY1 and RY2 via Q3 respectively in Figure 3(c) (
d), the relay RY1 is turned on, the relay RY2 is turned off, the relay contact ry1 of the relay RY1 is closed, and the relay contact ry2 of the relay RY2 is opened.

Therefore, at time t2, only the lamp L is shown in FIG.
It lights up as shown in e). Furthermore, a remote control signal R for lighting the miniature bulb M from a transmitter (not shown)
C is the terminal SI of the control unit 23 as shown in FIG.
When the signal is applied to G, signal processing is performed in accordance with the above, and a control signal in which the output P1 of the control section 23 is at the H level and the output P2 is at the L level is sent out. In this case, relay contact ry1 of relay RY1 is open, and relay contact ry of relay RY2 is open.
2 is closed, and at time t21, only the miniature ball M is shown in FIG. 3(f).
It lights up as shown.

Furthermore, in this state, a remote control signal R for turning off the light bulb M is sent from a transmitter (not shown).
C is the terminal SI of the control unit 33 as shown in C of FIG. 3(a).
When the signal is applied to G, signal processing is performed in accordance with the above, and the control section 23 sends out a control signal that causes the output P2 to become H level. In this case, the relay contact ry2 of the relay RY2 is opened, and the light bulb M is also turned off at time t3. At this time, of course, the output P1 of the control section 23 is at H level, and the relay RY
The relay contact ry1 of No. 1 is open, and the lamp L is off.

Next, in this state, the wall switch 1 is activated at time t.
When the control unit 23 is turned off at step 4, the control unit 23 is backed up for about 3.0 seconds by a self-power supply BAT consisting of a coin capacitor or the like. Therefore, if the wall switch 1 is turned on from time t4 to time ta (for example, 3.0 seconds or more, the rising edge of the reset input RESET is connected to the resistor R0 and the capacitor C).
0, the control section 23 is initialized by the reset means 11, and the light bulb M turns on or becomes inactive). When the time is longer than 1 second, the operation mode is set in which the miniature bulb M lights up, so the miniature bulb M is turned on. Naota
If it is within 1.5 seconds, the backup will output P1,
P2 is maintained in the previous state, the bulb M remains in the off state, and the lamp L remains in the off state.

Furthermore, when the remote control signal RC for turning off the light bulb M is applied to the terminal SIG of the control section 23 as shown in FIG.
3 sends out a control signal so that the output P2 becomes H level, and opens the relay contact ry2 of the relay RY2. Therefore, the light bulb M goes out at time t6. An operation that can turn on the lamp L without operating a transmitter (not shown) in this state will be described below.

To turn on the lamp L, turn off the wall switch 1 at time t7 and turn it on again after time tb (tb is, for example, within 1.5 seconds), that is, at time t8. It is possible. To explain the circuit operation caused by this operation, the power supply AC is cut off by turning off the wall switch 1 at time t7, the rectified pulsating voltage applied to the set input SET of the control unit 23 disappears, and the set input The time determining means 10 starts functioning via the set input determining means 9 which determines that SET is gone.

The time determining means 10 comprises, for example, a timer means, a counter means, etc., and detects the power cutoff detection signal of the power cutoff detection circuit 4 (in this case, a signal indicating that there is no rectified pulsating voltage applied to the set input SET). The output time tb is determined, and if this output time is within a predetermined time (for example, within 1.5 seconds), a signal is output that latches the output state forming means 7 to a predetermined state. As a result, the output P1 is held at H level, the relay RY1 is turned on and its relay contact ry1 is closed, and the lamp L is turned on at time t8. In this way, the time determination means 10 selectively controls the load state selection circuit 22 to select the operating state of the load (in this case, the lamp L), so even if the transmitter is not found, by shutting off the wall switch 1 within a predetermined time, Lighting loads can be activated.

When the remote control signal RC for turning off the lit lamp L is applied to the terminal SIG of the control section 23 as shown in E of FIG. 3(b), the output P1 becomes H.
level, and the relay contact ry1 of the relay RY1 is opened. Therefore, the lamp L is turned off at time t9. Further, the time determining means 10 determines that when the time of the power cutoff detection signal (signal input to the set input SET of the control unit 23) of the power cutoff detection circuit 4 is a predetermined time (within 1.5 seconds to 3.0 seconds),
That is, when the power supply AC is cut off within a predetermined time, no signal is sent to the output state forming means 7, and in this case, as described above, the load is self-maintained in the state before the cutoff.

Of course, if the power is restored or the wall switch 1 is turned on again after 3.0 seconds or more of the backup time of the self-power source BAT has elapsed, the bulb M will be turned on or the lamp L will be inactive. Here, as shown in FIG. 3(a), the wall switch 1 is turned off at time t10, and then, at time t11, the wall switch 1 is turned off as shown in FIG. 3(a). ) time < Tx < backup time of self-power supply BAT, and when the re-on operation is repeated within time td, the rectified pulsating voltage applied to the set input SET of the control unit 23 disappears, and the set input disappears. The time determining means 6 functions via the set input determining means 5, which detects the voltage application and voltage cut-off times of the Tx time width, determines that the signal is to normally light the lamp L, and determines the output state. A signal is sent to latch the forming means 7 for a predetermined period of time. As a result, the output P1 of the control section 23 becomes L level, the output P2 becomes H level, and the lamp L is turned on at time t12.

That is, the remote control device of the present invention has the main function (lighting up the lamp L, which is the main light source) of the lighting equipment, and the auxiliary function (lighting up the miniature bulb M. In the case of a lighting equipment with only one incandescent lamp, the power supply state is When the power is restored from a power outage, the operation of the auxiliary function is always given priority over the operation of the main function. When an artificial voltage change signal is detected, the operation is switched to give priority to the operation of the auxiliary function, and the main function is always operated.

The clock generating means 12 has a crystal X connected to a clock input CLOCK, and performs start-stop control of the entire control section 32 using a clock signal of an appropriate frequency. Further, the buzzer BZ is driven by the buzzer output bz of the buzzer output means of the control section 32 only when the state of the output state forming means 7 changes. This is set depending on whether there is one type of input code or multiple types of input codes, and is set by applying an L or H level signal to the mode setting input terminal MODE in advance, respectively.

Effects of the Invention The present invention provides a lighting load, a reception control circuit having a load state selection circuit that selectively controls the lighting load to be activated or deactivated by receiving a remote control signal in a receiving section, and a power source. A power cutoff detection circuit that detects a cutoff and an output time of a power cutoff detection signal from the power cutoff detection circuit are determined, and if the output time and the power cutoff operation mode are a predetermined time and operation mode, the lighting load is activated. Since the present invention includes at least a circuit that selects and controls the lighting load to a non-operating state and initializes the lighting load to an inactive state if the output time is outside of a predetermined time, a wall switch or the like can be used to set the predetermined operating time or
The state of the lighting load can be selectively controlled into the operating state by applying or cutting off the power depending on the operation mode. Therefore, even if a transmitter for remote control is not found, the lighting load can be turned on, and the power supply can be set to a specified value. When the power is restored after a power outage for more than an hour, the lighting loads are initialized to an inactive state, which has the effect of preventing the lighting loads from accidentally turning on when no one is around, making it safer. Alternatively, since the lighting load can be controlled by operating the transmitter, pull switches can be eliminated from lighting equipment.
It is possible to improve the design of lighting fixtures, and in particular, in lighting fixtures that are directly attached to the ceiling, the pull string of the pull switch can be eliminated, which has a remarkable effect on the surface of the densified surface.

Further, the invention according to claim 2 is the invention according to claim 1, in which the lighting load is self-maintained in the state before the power is cut off if the output time is within a second predetermined time shorter than the predetermined time. Therefore, if the power supply is cut off within a second predetermined time shorter than the predetermined time, if the self-holding means is provided to self-hold the lighting load in the state before the cutoff, even if a momentary power outage occurs, etc. This has the effect of preventing the state of the lighting load from changing inadvertently. Furthermore, the invention as claimed in claim 3, in the invention as claimed in claim 1, sets the predetermined time and operation mode by performing an arbitrary artificial operation to cut off the application of the power supply voltage in a power outage state. When a person performs a predetermined operation on a wall switch with the intention of turning on the lighting load, the lighting load can be turned on, which has the effect of eliminating the possibility of accidentally turning on the lighting load. .
