Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an illuminating device capable of switching the lighting state of an illuminating load and performing various settings and controls by a wireless signal transmitted from a remote control transmitter.

[0002]

2. Description of the Related Art Recently, lighting devices have been widely used in which a lighting state of a lighting load is switched by operating a remote control transmitter and transmitting a wireless signal using infrared rays as a transmission medium. Illumination equipment used for this type of illumination device often includes a receiving unit for receiving a wireless signal in the equipment main body.

[0003] When this type of lighting equipment is used in an office or the like, a plurality of lighting equipment are installed on a ceiling or the like in close proximity. In this manner, in a state where a plurality of lighting devices are arranged close to each other, in order to selectively switch the lighting state of a specific lighting device by a wireless signal, the wireless signal is selectively transmitted to a desired lighting device. It is necessary. As a technique for selectively allowing a wireless signal to reach a desired lighting fixture, a technique of performing an optical design to limit a range in which a wireless signal can be transmitted and received for each lighting fixture, and a technique of setting a channel on the lighting fixture side. There is a technique in which a channel is designated by a wireless signal so that an instruction of a wireless signal is received only by a desired lighting fixture.

[0004] For example, as a technique based on the optical design as described above, there is a technique for narrowing the spread angle of a beam of a wireless signal transmitted from a wireless transmitter, as described in Japanese Patent Application Laid-Open No. 9-106706. .

[0005]

However, even if an optical design is made to narrow the spread angle of the wireless signal beam as described above, the wireless signal is not reflected by a wall or the like due to reflection from a wall or the like. Lighting fixtures may be wrapped around and unnecessary lighting fixtures may operate incorrectly. To optically solve such a malfunction caused by the wraparound of the wireless signal, a special optical element for transmitting and receiving the wireless signal is required, which leads to an increase in cost.

On the other hand, if a channel is set, this kind of malfunction can be avoided. However, when the lighting fixture is grounded, a channel is set for each lighting fixture, and there is a problem that the construction work becomes troublesome.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to turn on / off only a desired lighting load by an instruction using a wireless signal without making a special optical design or setting a channel. It is an object of the present invention to provide a lighting device that can perform the lighting.

[0008]

According to a first aspect of the present invention, there is provided a remote control transmission provided with a lighting load, a human sensor for detecting the presence or absence of a person in a detection area set within an illumination range by the lighting load. A control unit for receiving at least operation information instructing to turn on / off a lighting load transmitted by a wireless signal from a device during a period in which it is determined that a person is present in the detection area based on an output of the human sensor. Is provided. According to this configuration, during the period in which it is determined that a person is present in the detection area of the human sensor, the lighting load of the lighting load is controlled by the wireless signal from the remote control transmitter.
Since the operation information for instructing turning off can be accepted, if there is a plurality of lighting loads and the presence of a person is not detected by the presence sensor, the lighting load corresponding to the presence sensor is turned on / off. An instruction to turn off or the like cannot be accepted, and as a result, it is possible to prevent unnecessary lighting loads from being turned on and off by mistake. In addition, the optical design that narrows the spread angle of the beam of the wireless signal is not required, and the setting of the channel is not required, so that the provision can be performed at a relatively low cost, and the construction work is facilitated.

According to a second aspect of the present invention, a wireless signal is transmitted from a remote control transmitter provided separately from a lighting load, a human sensor for detecting the presence or absence of a person in a detection area set within an illumination range of the lighting load. Operation information discriminating means for discriminating a plurality of types of operation information to be provided. And a control unit that can receive the remaining operation information defined by the operation information determination unit regardless of the output of the human sensor. According to this configuration, during the period in which it is determined that a person is present in the detection area of the human sensor, it is possible to receive operation information for instructing the lighting load to be turned on / off by a wireless signal from the remote control transmitter, If the presence of a person is not detected by the human sensor when there are multiple lighting loads, the lighting load corresponding to the human sensor cannot receive the light-on / light-off instruction. It is possible to prevent unnecessary lighting loads from being turned on / off by mistake. In addition, the optical design that narrows the spread angle of the beam of the wireless signal is not required, and the setting of the channel is not required, so that the provision can be performed at a relatively low cost, and the construction work is facilitated. Further, the type of operation information transmitted from the remote control transmitter is determined, and depending on the type of operation information, it is possible to receive the information regardless of the output of the human sensor. If the operation information to turn off the light can be accepted regardless of the output of the human sensor,
All lighting loads in the room can be turned on and off collectively, which is convenient.

According to a third aspect of the present invention, in the first or the second aspect of the present invention, the control unit determines whether or not a person is no longer present in the detection area based on the output of the human sensor. A reception timer that limits the receivable period of the operation information, and makes it possible to receive the operation information in the receivable period in addition to the period in which it is determined that a person is present in the detection area based on the output of the human sensor. Things. According to this configuration, even after the presence sensor is no longer detected by the presence sensor, the operation information can be received within the reception enable period limited by the reception timer. It is possible to turn off the lighting load after getting out of the room, and the usability is further improved.

According to a fourth aspect of the present invention, in any one of the first to third aspects of the present invention, the detection area of the motion sensor is set to be smaller than the illumination range of the illumination load. In this configuration, the lighting loads are individually turned on / off by wireless signals from outside the lighting range due to the lighting loads.
It is not possible to turn off the lights, so that it is possible to reduce the waste of power by turning on the lighting load having the lighting range in a place where no people are present, and to reduce the lighting load even when there is a person in the lighting range. It is possible to turn on / off the neighboring lighting loads by mistake when there are multiple lighting loads because receiving individual lighting / lighting off instructions is restricted when there is a person within a specific range. Is reduced.

According to a fifth aspect of the present invention, an illumination load, a plurality of human sensors for detecting the presence or absence of a person in a detection area respectively set in an illumination range by the illumination load, and a separately provided remote control transmitter are provided. And a control unit for determining whether to accept operation information by a wireless signal according to a combination of presence or absence of a person in each detection area based on an output of each human sensor. According to this configuration, by providing a plurality of human sensors, a plurality of detection areas can be set within the illumination range of the illumination load, and when a person is present in a specific detection area, a signal from the remote control transmitter is transmitted. Since operation information can be received, unnecessary lighting loads do not receive operation information by mistake even when a plurality of lighting loads exist. It can be prevented from being turned off. In addition, the optical design that narrows the spread angle of the beam of the wireless signal is not required, and the setting of the channel is not required, so that the provision can be performed at a relatively low cost, and the construction work is facilitated.

According to a sixth aspect of the present invention, in the fifth aspect of the invention, the remote control transmitter is capable of transmitting a plurality of types of operation information, and the control unit determines the type of the operation information. And differentiating the receivable operation information among the operation information included in the received wireless signal in accordance with the combination of the presence or absence of a person in each detection area based on the output of each human sensor. According to this configuration, different operation information can be received depending on which area of the plurality of areas set by the combination of the detection areas by the plurality of human sensors, depending on which area the person is in. For example, when a person is present in a specific area, the lighting loads can be individually turned on and off, and when a person exists in another area, a plurality of lighting loads can be turned on collectively.

According to a seventh aspect of the present invention, in the first to sixth aspects of the invention, the lighting load, the human sensor, and the control unit are attached to a single appliance body. According to this configuration, since the lighting load, the human sensor, and the control unit are attached to one fixture main body, if the fixture main body is installed on a ceiling or the like, the above-described various functions can be realized. Becomes easier.

[0015]

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) The lighting device of this embodiment is
As shown in FIG. 1, a lighting fixture 1 having a lighting load 11
And a remote control transmitter 2 for giving an instruction to turn on / off the lighting load 11 by a wireless signal using infrared as a transmission medium.

The lighting fixture 1 includes a control unit 15 having a microcomputer as a main component. The control unit 15 gives an instruction to a dimming circuit 16 to which the lighting load 11 is connected, so that the lighting load 11 is controlled.
Control of turning on / off or dimming. Light control circuit 16
May be used either to set the dimming level stepwise (referred to as step dimming) or to set the dimming level continuously (referred to as continuous dimming). That is, the control unit 15 is provided with the lighting illuminance setting unit 17, and the dimming level is set to the lighting illuminance setting unit 1.
7 to the dimming circuit 16. The control unit 15 is connected to a receiving unit 13 that receives a wireless signal from the remote control transmitter 2. The control unit 15 decodes the instruction given by the wireless signal.

On the other hand, the remote control transmitter 2 includes an operation unit 21 including a push button switch for performing various operations to the control unit 15, and operation information corresponding to the operation of the operation unit 21 is transmitted to the signal generation unit 22 by the signal generation unit 22. The signal sequence is converted into a signal sequence of a predetermined form, and the signal sequence is transmitted from the transmission unit 23 as a wireless signal. As the operation information, at least an instruction to change the lighting state (lighting / extinguishing / light control) of the lighting load 11 may be provided, but an instruction to change various settings described later is transmitted as operation information by a wireless signal. Is also good.

The luminaire 1 is provided with a motion sensor 12 for setting a detection area within the illumination range of the illumination load 11 and detecting the presence or absence of a person in the detection area.
As the human sensor 12, for example, a sensor that detects a heat ray radiated from a human body by a pyroelectric infrared sensor is used. In the present embodiment, the lighting holding time set as the period during which the presence of a person in the detection area is detected by the human sensor 12 and the fixed time after the person is no longer detected by the human sensor 12 is the detection area. It is determined that there is a person inside. The lighting holding time is limited by an illumination timer 18 provided in the control unit 15, and the illumination timer 18 is configured to be able to trigger again. Thus, by setting the lighting holding time, even if a state where a person is temporarily not detected by the human sensor 12 even though a person is present in the detection area occurs, the person is continuously detected. Presence can be assumed to have been detected.

Further, the control unit 15 sets a receivable period set separately from the lighting holding time as a fixed time from the time when it is determined based on the output of the human sensor 12 that the person is no longer in the detection area. A time limit reception timer 19 is also provided.

Further, a brightness sensor 14 using a photoelectric element such as CdS is connected to the control unit 15, and the brightness sensor 14 detects the ambient illuminance.
Generally, the illumination load 11 is turned on when the ambient illuminance is low. Therefore, the ambient illuminance is monitored by the brightness sensor 14, and the control unit 15 forcibly turns off the illumination load 11 when the ambient illuminance is higher than a specified value. Control to keep the state.

In this embodiment, the motion sensor 1
2, a period in which a person is determined to be present in the detection area based on the output of No. 2 (that is, a period in which a person is detected by the human sensor 12 and a period in which the lighting holding time is limited by the illumination timer 18), and During a period in which the receivable period is limited by the timer 19, the reception of the operation information by the wireless signal from the remote control transmitter 2 is permitted. Conversely, operation information by a wireless signal is not accepted except during these periods. Therefore, even if a plurality of lighting fixtures 1 are arranged adjacent to each other, if no person is detected by the human sensor 12 (that is, it is not a period from the detection of a person to the end of the acceptable period). However, the operation information by the wireless signal is not received, and as a result, the lighting state of the lighting load 11 such as lighting, turning off, and dimming is not changed. That is, it is possible to prevent an erroneous operation such as turning on the unnecessary lighting load 11 or erroneously turning off the lighting load 11 to be turned on.

As described above, the lighting state of the illumination load 11 can be changed according to the presence or absence of the detection of the person by the human sensor 12, so that the detection area of the human sensor 12 is different from the illumination range by the illumination load 11. Make them equal or set smaller than the illumination range. In particular, if the detection area is set smaller than the illumination range, the operation of turning on the illumination load 11 cannot be performed from outside the illumination range, so that the possibility of erroneous operation can be further reduced.

The dimming level set in the lighting illuminance setting unit 17, the lighting holding time limited by the illumination timer 18, and the receivable period limited by the reception timer 19 can be set by wireless signals from the remote control transmitter 2. If such a wireless signal is not detected by the human sensor 12, the wireless signal is not accepted by the control unit 15, so that erroneous setting to another lighting fixture 1 can be prevented. As described above, a wireless signal can be selectively transmitted to each lighting fixture 1 without using a channel. In addition, there is no need to narrow the spread angle of the beam of the wireless signal from the remote control transmitter 2 so that the optical design can be reduced. Is also easy.

In the present embodiment, the lighting fixture 1 includes a lighting load 11, a human sensor 12, a receiving unit 13, a brightness sensor 14, a control unit 15, and a dimming circuit 16 as one fixture main body (not shown). Since the lighting fixture 1 is installed and constructed on a ceiling or the like, not only the lighting load 11 but also the human sensor 12, the receiving unit 13, and the brightness sensor 1 are integrated.
4 can also be installed and constructed, which facilitates the construction work.

Next, an example of use of the lighting device of the present embodiment will be described with reference to FIG. In FIG. 2, two lighting devices 1a, 1
b is arranged adjacent to the ceiling 3. Both lighting fixtures 1a,
1b has the same configuration as the lighting fixture 1 shown in FIG.
a, 1b. In FIG. 2, each lighting fixture 1 is shown.
The detection areas a and 1b are shown as Aa and Ab, respectively.

Here, the remote control transmitter 2 detects the detection area A
Assuming that the operation is performed by the operator 5 located at the position a, the wireless signal from the remote control transmitter 2 can be received by the two luminaires 1a and 1b at the illustrated position. Here, since the operator 5 is present in the detection area Aa, the operation of the control unit 15 described above enables the wireless signal to be accepted only in the lighting fixture 1a. In other words, it is possible to receive the operation information by the wireless signal only in the lighting fixture 1a that detects the operator 5 by the human sensor 12 among the two lighting fixtures 1a and 1b arranged adjacent to each other. An erroneous operation due to the information being transmitted to the lighting fixture 1b is prevented. In this manner, the lighting state of only the lighting load 1a is changed, or the lighting illuminance setting unit 1
7, the settings of the illumination timer 18 and the reception timer 19 can be changed.

Here, various examples of setting the detection area A of the human sensor 12 to be smaller than the illumination range of the illumination load 11 are shown in FIG. However, in the illustrated example, the receiving unit 13 is separated from the instrument body 1. FIG. 3A illustrates a case where the detection area A is set in a range narrower than the illumination range with the center immediately below the lighting fixture 1 as a center. In this setting, multiple lighting fixtures 1
Can be surely prevented from overlapping the detection area A of the human sensor 12 even if the wireless communication devices are arranged close to each other, and each lighting load 1 can individually receive a wireless signal. FIG. 3B shows a case where the detection area A is set in a range narrower than the illumination range with the center immediately below the receiving unit 13 as a center. In this setting, the remote control transmitter 2 and the receiver 1
Since the wireless signal is transmitted in a state where the distance from the wireless communication device 3 is relatively short, in combination with the fact that the detection area A is narrowed, the desired lighting equipment 1 can reliably receive the wireless signal. Further, FIG. 3 (c) shows a case where the detection area A of the human sensor 12 is set within a range of a predetermined distance H from the ceiling 3, and even if there is a pet near the floor, no erroneous detection is performed. The wireless signal can be accepted only when the remote control transmitter 2 is operated while the remote control 5 is standing, thereby preventing erroneous operation. Thus, if the setting example of the detection area A shown in FIG. 3 is appropriately adopted according to the purpose, the possibility of erroneous operation can be further reduced.

(Embodiment 2) In this embodiment, a plurality of types of operation information can be transmitted from the remote control transmitter 2, and as shown in FIG. Is provided in the control unit 15 of the lighting fixture 1. Other configurations are the same as in the first embodiment.

In the first embodiment, the period during which the human sensor 12 detects the presence of a person in the detection area and the reception timer 1
9, the wireless signal from the remote control transmitter 2 is configured to be accepted during the acceptable period, but depending on the type of operation information, the wireless signal is transmitted regardless of the detection of the person by the human sensor 12. Acceptance may be required. For example, it is required that operation information for turning on / off a plurality of lighting loads 11 arranged in a room collectively even if no person is detected by the motion sensor 12 is received. Therefore, in this embodiment,
A control signal discriminating unit 20 is provided to discriminate between operation information that can be received when a human is detected by the human sensor 12 and operation information that can be received regardless of detection of a human by the human sensor 12. ing.

When the above-described configuration is used, the operation information for individually giving instructions to each control unit 15 and the operation information for giving instructions collectively to a plurality of control units 15 are transmitted from the remote control transmitter 2. . That is, as in the first embodiment, two lighting fixtures 1a and 1b (see FIG. 2) are arranged close to each other, and the operator 5 is detected by the human sensor 12 provided in the lighting fixture 1a. The former operation information can be received only by the lighting equipment 1a, and the latter operation information can be received by both the lighting equipment 1a.
Acceptance is possible at a and 1b. Other configurations and operations are the same as those of the first embodiment.

(Embodiment 3) This embodiment has a configuration in which a human sensor 24 is added to the configuration of Embodiment 1 as shown in FIG. The motion sensor 24 has a detection area different from that of the motion sensor 12, and the control unit 15 controls the motion sensor 2.
The lighting load 11 is turned on and off regardless of the wireless signal from the remote control transmitter 2 in accordance with the presence or absence of the detection of the person 4.

This embodiment can be used, for example, as follows. Now, two lighting fixtures 1a and 1b having the same configuration as the lighting fixture 1 shown in FIG. 5 are arranged close to each other on the ceiling 3 as shown in FIG.
a, A2b are set within a range reaching the floor, and the motion sensor 12
The detection areas A1a and A1b are set in a predetermined range higher than the floor. Here, in the illustrated example, since the persons 5, 5 'are present in both the detection areas A2a, A2b, the lighting loads 11 of both the lighting fixtures 1a, 1b are turned on. In order that the wireless signals from the remote control transmitter 2 can be received by the lighting fixtures 1a and 1b, the detection area A1 of the human sensor 12 is required.
a, it is necessary that a person exists in A1b. Therefore,
To change the illuminance using the remote control transmitter 2, the person (operator) 5 present in the illumination range of the luminaire 1a only needs to stand up to enter the detection area A1a. In this state, since no person is detected in the detection area A1b, the lighting state of the lighting fixture 1b is not changed by the wireless signal from the remote control transmitter 2.

With the above configuration, the lighting fixtures 1a, 1b
To turn on / off the lighting load 11 according to the presence or absence of a person in the lighting range, and to enable the lighting fixtures 1a and 1b to selectively receive wireless signals from the remote control transmitter 2. Both are possible. Note that the above-described use example is an example, and the number of motion sensors is not limited to two, and the operation of the control unit 15 and the setting of the detection area for each motion sensor are particularly limited. Not something. Other configurations and operations are the same as those of the first embodiment.

(Embodiment 4) In this embodiment, as shown in FIG. 7, two human sensors 12 and 24 are provided, and the control signal discriminating section 20 is provided to the control section 15 as in the second embodiment. It is provided. Both human sensors 12, 24 have different detection areas. Further, similarly to the second embodiment, the remote control transmitter 2 can transmit a plurality of types of operation information as wireless signals, and the control signal determination unit 20 determines the type of the operation information.

By the way, in the second embodiment, the operation information is divided into two types and discriminated. However, in the present embodiment, the operation information can be received in association with the combination of the presence or absence of the detection of the human by the human sensors 12 and 24. Operation information (signal group) is classified into four types. That is, the two human sensors 12, 24
, Each one human sensor 12, 24
The two states in which a person is detected by the two persons, the state in which both persons 'sensors 12 and 24 do not detect a person, and the two persons' sensors 12 and 24
Since there are four states, ie, a state where a person is detected, the type of operation information is determined in association with these four states.

Table 1 shows the above relationship. That is, four types of control signal groups α, β, γ, and δ are transmitted from the remote control transmitter 2 as operation information by wireless signals. On the other hand, the control unit 15 controls the presence sensors 12 and 24.
Which control signal groups α, β, γ, and δ can be accepted depending on whether or not a person is detected (represented by ○) and the human sensor does not detect a person (represented by ×) Is determined.

[0038]

[Table 1]

An example of use of this embodiment will be described with reference to FIGS. In the illustrated example, the lighting fixture 1 shown in FIG.
Two luminaires 1a and 1b having the same configuration as above are arranged on the ceiling 3 adjacent to each other. In the lighting fixture 1a, the detection area A1a of the motion sensor 12 is set within the range of the detection area A2a of the motion sensor 24. In the lighting fixture 1b, the detection area A1b of the motion sensor 12 and the detection area of the motion sensor 24 are set. A2b is set so as to hardly overlap.

Assuming that such a setting has been made,
As shown in FIG. 8, the operator 5 determines
If not detected as shown in Table 1,
Only the control signal group δ will be accepted. The control signal group δ includes an instruction to turn on / off the lighting loads 11 of the two lighting fixtures 1a and 1b collectively.

As shown in FIG. 9, when the operator 5 exists in the detection area A2a of the human sensor 24 provided in the lighting fixture 1a, but does not exist in the detection area A1a of the human sensor 12 ( That is, when a person is detected only by the human sensor 24), only the control signal group β can be received. In this state, the lighting fixture 1b can receive only the control signal group δ and cannot receive the control signal group β. That is, the control signal group β includes the lighting fixtures 1a and 1b.
Is selectively transmitted to the lighting load 11.
An instruction to turn off the light, an instruction to change the set values of the illumination timer 18 and the reception timer 19, and the like are included.

As shown in FIG. 10, when the operator 5 is present in both the detection area A1a of the human sensor 12 and the detection area A2a of the human sensor 24 provided in the lighting fixture 1a, the control signal group γ becomes acceptable. In this state as well, since the control signal group γ is not received by the lighting fixture 1b, the control signal group γ is transmitted only to the lighting fixture 1a. For example, an instruction to change the dimming amount is performed by the control signal group γ. become.

As shown in FIG. 11, when a person is present in the detection area A1b of the human sensor 12 of the luminaire 1b, no human is detected by the human sensor 24. Will be accepted. This control signal group α can be selectively received only by the lighting fixture 1b. Here, since the detection area A1b of the human sensor 12 is set in the periphery of the illumination range of the lighting fixture 1b, it is convenient to instruct the lighting load 11 to be turned on and off at this position. That is, the control signal group α includes an instruction to turn on / off the lighting load 11. Other configurations and operations are the same as those of the second embodiment.

In the central control device 30, the switch 31, the terminal 32 with a human sensor, the remote control receiver 33, and the terminal 34 are associated with each other by an address. Therefore, when the switch 31 is operated, the operation information is transmitted to the terminal 34 associated with the address, and the lighting state of the lighting load 11 connected to the terminal 34 can be controlled.

By the way, in the illustrated example, a plurality (two in the figure)

The central control device 30 has the function of the control unit 15 in the first embodiment. When a person is detected by the human sensor-equipped terminal 32 in each of the groups G1 and G2, the wireless signal received by the remote control receiver 33 Can be accepted. The operation information of the wireless signal received by the remote control receiver 33 is transmitted to the central control device 30 by a transmission signal transmitted on the signal line 36, and the central control device 30 transmits control data corresponding to the operation information to the terminal 34. Then, the lighting state of the lighting load 11 is controlled.

The human sensor 12 includes a pyroelectric infrared sensor that detects a heat ray radiated from a human body, an ultrasonic sensor that detects a change in distance by transmitting and receiving ultrasonic waves to determine the presence or absence of a person, and emits light. A photoelectric sensor that receives light and determines the presence or absence of a person based on a change in the amount of received light can be used.

[0049]

According to the first aspect of the present invention, a wireless signal is transmitted from a remote control transmitter provided separately from an illumination load, a human sensor for detecting the presence or absence of a person in a detection area set within an illumination range by the illumination load. A control unit for receiving at least the operation information for instructing the lighting load to be turned on and off transmitted by the sensor during a period in which it is determined that a person is present in the detection area based on the output of the human sensor. In the period in which it is determined that a person is present in the detection area of the human sensor, operation information for instructing the lighting load to be turned on / off by a wireless signal from the remote control transmitter can be received. If the presence sensor does not detect the presence of a person when it is present, the lighting load corresponding to the presence sensor can accept instructions such as turning on and off. , There is an advantage that it is possible to prevent the cause resulting in the turning on and off accidentally unnecessary lighting load.

A control unit that determines whether or not to accept operation information by a wireless signal according to a combination of the presence or absence of a person in each detection area based on the output of each human sensor. By providing, it is possible to set a plurality of detection areas within the illumination range of the lighting load, and it is possible to receive operation information from the remote control transmitter when a person is present in a specific detection area, Even if a plurality of lighting loads are present, unnecessary lighting loads do not receive operation information by mistake, and for example, it is possible to prevent an adjacent lighting load from being turned on / off by mistake. There is an effect that theft can be. Moreover, there is no need for an optical design that narrows the spread angle of the beam of the wireless signal, and there is no need to set channels, so that it can be provided at a relatively low cost, and the construction work is facilitated. .

According to a sixth aspect of the present invention, in the fifth aspect of the invention, the remote control transmitter is capable of transmitting a plurality of types of operation information, and the control unit is provided with operation information determination means for determining the type of the operation information. According to the combination of the presence or absence of a person in each detection area based on the output of each human sensor, the receivable operation information among the operation information included in the received wireless signal is made different, and Different operation information can be accepted depending on which area of the plurality of areas set by the combination of the detection areas detected by the sense sensor. For example, when a person exists in a specific area, The advantage is that it is possible to turn on / off the lighting loads individually, and to turn on multiple lighting loads at once when a person is present in another area. That.

According to a seventh aspect of the present invention, in the first to sixth aspects of the present invention, the lighting load, the human sensor and the control unit are attached to one apparatus main body. Since the sensor and the control unit are attached to one instrument main body, if the instrument main body is installed on a ceiling or the like, the above-described various functions can be realized, and there is an advantage that installation work is facilitated.
