DETAILED DESCRIPTION OF THE INVENTION

[0001]

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, a remote control device in which an illumination state is selected by a transmitter for transmitting infrared rays or the like is known. A technique for changing the lighting state of the lighting equipment in the system of the wall switch from the first lighting state to the second lighting state including the light-off state by shutting off the wall switch in the room within a predetermined time is disclosed in Japanese Patent Publication No. 56-1981. Conventionally, as shown in JP-A-7277.

Further, the load state can be selectively controlled by a remote control, and even if a transmitter for the remote control is not found, the load can be turned on by shutting off the power supply by a wall switch or the like within a predetermined time. In some cases, if the previous state is the operation state of the load, the load can be immediately activated simply by turning on the power again with a wall switch or the like.

[0004]

In the case of a remote control device in which the lighting state is selected by the above-mentioned transmitter for transmitting infrared rays or the like, the lighting device itself does not have a lighting switch. There was an inconvenience that it could not be turned on without a transmitter that was easily lost.

That is, for example, when the light is turned off by the transmitter when going out and the light is turned on when returning home, the transmitter must be found in a dark room.
It is well known that it is very inconvenient. In addition, even if the wall switch in the room is turned on again, the light remains off, so that it is inconvenient to find the transmitter and then operate the transmitter to turn it on.

Next, in the case of Japanese Patent Publication No. 56-7277, there is an inconvenience that the light cannot be turned on unless the user has to go to the place where the wall switch is located. In addition, even if the load state can be selectively controlled by remote control, and the load can be brought to a state before the load is cut off by shutting off a power supply for a predetermined time by a wall switch or the like without using a transmitter for remote control, for example, If the state before the interruption is the inoperative state of the load, there is an inconvenience that the load cannot be operated immediately even if the power is turned on again by the wall switch.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to make it possible to turn on a lighting load by a wall switch or the like without a transmitter. It is another object of the present invention to provide a remote controller for lighting, in which, when power is restored from a power failure longer than a predetermined time, the lighting load is inactivated and the lighting load is prevented from lighting when nobody is present.

The object of the present invention described in claim 2 is, in addition to the object of the present invention described in claim 1, in that the operation state of the lighting load is not accidentally switched even if an instantaneous power failure or the like occurs. To provide a remote controller for lighting. Further, the object of the invention described in claim 3 is that in addition to the object of the invention described in claim 1 above, the lighting load is selectively controlled by turning off the power supply by manipulating a wall switch or the like artificially. It is an object of the present invention to provide a lighting remote controller that can blink and switch to another auxiliary load.

It is.

According to a second aspect of the present invention, in the first aspect of the present invention, if the output time is within the second predetermined time shorter than the predetermined time, the illumination load is self-maintained in a state before power-off. The self-holding means is provided.
Further, according to a third aspect of the present invention, in the first aspect of the present invention, the predetermined time and the operation mode are set by performing an arbitrary artificial application and cutoff operation of a power supply voltage in a power failure state.

[0011]

According to the first aspect of the present invention, the lighting load can be selectively controlled to the operating state only by interrupting the power supply with the wall switch or the like for a predetermined operation time and operation mode. The lighting load can be turned on even if the transmitter for remote control is not found, and the lighting load is initialized to an inactive state when the power is restored after a power outage for more than a predetermined time. In addition, when there is no person, the lighting load does not light up carelessly, which is safe.

According to the second aspect of the present invention, when the power supply is shut off within a second predetermined time shorter than the predetermined time, if the self-holding means for self-holding the illumination load in the state before the power cutoff is provided, an instantaneous power failure or the like can occur. Even if it happens, the state of the lighting load does not change carelessly. According to the third aspect of the present invention, the wall switch is operated by the user with the intention of turning on the lighting load by setting an arbitrary artificial application and cutoff of the power supply voltage from a power failure state to a predetermined operation time and operation mode. The lighting load can be turned on only when is operated, so that the lighting load is not erroneously turned on.

[0013]

The present invention will be described below with reference to examples. FIG. 1 is a circuit diagram according to the present embodiment. A lighting load including a lamp L and a bead ball M is connected to a power supply AC via a wall switch 1 in a room and relay contacts ry ₁ and ry ₂ . A reception 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. By the receiver 2 ₁ in the reception control circuit 2 is received remote control signals RC from the transmitter, the lighting load by subsequent load state selection circuit 2 ₂ is selected controlled actuated or deactivated.

The output of the receiving section 2 ₁ applied as a remote control signal input to the terminal SIG of the control unit 2 ₃ consisting of IC in the load state selection circuit 2 _2. Functions of the control unit 2 ₃ will be described later, by a control signal generated on the output P _1, P _2,
Transistor Q ₂ , relay RY _{1 and} transistor Q ₃ ,
Controlled relay RY ₂ are each corresponding relay contact ry _1, ry
_By controlling the opening and closing of the lamp ₂ , the lamp L and the bead ball M are each opened and closed.

Next, a DC power supply circuit for supplying DC power to the reception control circuit 2 will be described with reference to the upper half of the figure.
After smoothing by a capacitor C ₂ through the diode D ₂ as well as full-wave rectified by the rectifier BR, are constant voltage at the DC power source 3 consisting of the constant voltage circuit surrounded by a dotted line. The smoothed voltage VB of the capacitor C ₂ is the transistor Q _2, Q ₃
In is supplied to the relay RY _1, RY ₂ circuits each being controlled, the output voltage VC of the DC power supply 3 is supplied to the circuits other than the relay circuit in the receive control circuit 2.

Next, resistive power-off detection circuit 4 for detecting the interruption of the power supply AC is set in a rectified pulsating voltage before the rectifier BR entering the diode D _2, which via a diode D ₁ R ₁ shows an example connected in series to the series circuit of R _2. The divided voltage of the resistors R _1, R ₂ are connected to the set input SET of the control unit 2 _3. Next, the operation of this embodiment will be described with reference to FIGS.

Now, the wall switch 1 is turned on at time t ₁ as shown in FIG. 3A, and then a remote control signal RC from a transmitter (not shown) is applied as shown in FIG. Once in the terminal SIG of the control unit 2 _3, code determining means 6 through the input means 5 of the controller 2 ₃ determines the code of the remote control signals RC, the remote control signal RC for lighting the lamp L If it is a signal, the output state forming means (in this example, a latch type for holding the output state) 7 is latched in a predetermined state, and the output P ₁ is output via the output means 8 as shown in FIG. A control signal having an L level and an output P ₂ at an H level as shown in FIG. These signals control the relays RY ₁ and RY ₂ through the transistors Q ₂ and Q ₃ , respectively, as shown in FIGS. 3C and 3D. The relay RY ₁ is turned on and the relay RY ₂ is turned off. , relay contact ry ₁ of the relay RY ₁ is controlled to a closed, relay contact ry ₂ of the relay RY ₂ is opened.

Therefore, at time t _{2, only} lamp L
Lights up as shown in (e). Further, a remote control signal for lighting the bead ball M from a transmitter (not shown)
When RC is applied to the terminal SIG of the control unit 2 _3, as shown in B of FIG. 3 (a), signal processing is performed according to the above, the control unit 2 ₃
Output P ₁ sends out the control signal H level, the output P ₂ is at the L level. And in this case, the relay contact ry ₁ is opened the relay RY _1, relay contact ry ₂ of the relay RY ₂ is in the closed,
Lit as shown in Mamedama M although only 3 (f) at time t _21.

Further, in this state, a remote control signal RC for turning off the bead ball M from a transmitter (not shown) is used.
There When applied to the terminals SIG of the control unit 3 ₃ As shown in C of FIG. 3 (a), the signal processing according to the above is performed, the control unit 2 ₃ sends a control signal output P ₂ becomes H level . And in this case it becomes relay contact ry ₂ of the relay RY ₂ is opened,
Mamedama M also turned off at time t _3. At this time, the output P ₁ of the course controller 2 ₃ is H level, the relay contact ry ₁ of the relay RY ₁
Is open, and the lamp L is in the off state.

Next, in this state, the wall switch 1 is turned on at time t.
When turned off by _4, the control unit 2 ₃ by self-powered BAT consisting Koindensa or the like, and is about 3.0 seconds backup. Therefore, the wall switch 1 is switched from time t ₄ to time ta.
(If t is, for example, 3.0 seconds or more, the reset input RESE
Rise of T is, a resistor R _0, slowed down by the time constant of the capacitor C _0, the control unit 2 ₃ is initialized by the reset means 11, the lighting or non-operating state of Mamedama M) at a later time when turned on t _5, when in FIG. 3 ta is more than 3.0 seconds, since the set to the operation mode Mamedama M is lit, Mamedama M is illuminated. If ta is within 1.5 seconds, the outputs P ₁ and P ₂ are held in the previous state by backup, the bead ball M is turned off, and the lamp L is turned off.

A remote control signal for turning off the bead ball M as shown in FIG.
When RC is applied to the terminal SIG of the control unit 2 _3, the control unit 2 ₃ output P ₂ is sent a control signal which becomes H level, the relay contact ry ₂ of the relay RY ₂ open. Therefore beans sphere M is turned off at time t _6. An operation in which the lamp L can be turned on without operating a transmitter (not shown) in this state will be described below.

[0022] The lamp once time tb is turned off at time t ₇ the wall switch 1 to L to the lighting state (tb is within, for example, 1.5 seconds) to turn on again in after the lapse, that is the time t ₈ It is possible by operation. Describing the circuit operation by the operation, the power supply AC is interrupted by turning off the wall switch 1 at time t _7, rectified pulsating voltage that has been applied to the set input SET of the control unit 2 ₃ disappears, The time judging means 10 starts functioning via the set input judging means 9 for judging that the set input SET has disappeared.

The time judging means 10 comprises, for example, timer means, counter means, and the like, and outputs a 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 the output time is within a predetermined time (for example, within 1.5 seconds).
, A signal for latching the output state forming means 7 in a predetermined state is output. This output P ₁ is held at H level, the relay RY ₁ is turned on its relay contact ry ₁ is closed, the lamp L is assumed to be lit at time t _8.
In this way, the time determination means 10 can load the load state selection circuit 2
_{Since 2} is selectively controlled to operate the load (the lamp L in this case), the lighting load can be operated by shutting off the wall switch 1 within a predetermined time even if the transmitter is not found.

[0024] Note that when the remote control signal RC for turning off the lamp L is lit is applied to the terminal SIG of the control unit 2 _3, as shown in E of FIG. 3 (b), the output P ₁ is at the H level, the relay contact ry ₁ of the relay RY ₁ and open. Therefore lamp L is turned off at time t _9. Time determination means 10
Is a power cutoff detection signal of the power cutoff detection circuit 4 (control unit ₂₃₎
(The signal input to the set input SET) is a predetermined time (1.
5 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 returns to the state before the cutoff. Self-maintained.

Of course, when the power is restored or the wall switch 1 is turned on after elapse of 3.0 seconds or more of the backup time of the self-power supply BAT, the bead ball M is turned on or the lamp L is in an inoperative state. Here, as shown in FIG.
Off the wall Suittchi 1 at _10, then the wall switch 1 at time t ₁₁ the normal instantaneous power failure as shown in FIG. 3 (a) (within about 0.5 seconds) Time <Tx <backup time of the self-power supply BAT , when repeatedly cycled during operation within the time td, the control unit 2 ₃ sets the input rectified pulsating voltage that has been applied to the sET disappears, determining a set input determination unit 5 that the set input is exhausted The time judging means 6 functions to detect the voltage application and the voltage cutoff time in the width of the Tx time, judge that the signal is a signal for normally lighting the lamp L, and send a signal for latching the output state forming means 7 for a predetermined time. I do. Thereby, the control unit 2 ₃ output P ₁ is L level, the output P ₂ is H
Level, and the lamp L is lit state at time t _12.

That is, the remote control device of the present invention has a main function (lighting the lamp L as a main light source) and an auxiliary function (lights the pea ball M.) When the power is restored from the power failure state, the operation of the auxiliary function always takes precedence over the operation of the main function, and when the power is restored from the power failure state, When an artificial voltage change signal is detected, the operation of prioritizing the operation of the auxiliary function is switched, and the operation of the main function is always performed.

[0027] Note that the clock generating means 12 crystal X to start-stop controls the entire control unit 3 ₂ clock signal of appropriate frequency is coupled to the clock input CLOCK. The buzzer BZ output state buzzer output means of the buzzer output is intended to be driven also the mode setting means in bz 13 when the state is changed to the viewing control unit 3 _{and second} forming means 7 Load number or the remote control signal RC of Are set according to whether one or more types of input codes are provided, and are set by providing an L or H level signal to the mode setting input terminal MODE in advance.
