And a slave unit B that transmits a signal for setting the control state of at least the lighting device C, and an environment detection unit 1 that detects the state of the environment and changes in the environment in the detection area;
A master unit A that receives a signal from the receiving unit 2 and a main control unit 3 that turns on / off or dims the lighting device C based on the signal received by the receiving unit 2 and the detection information of the environment detecting unit 1
And a manually operable unit (for example, a push button switch or a slide switch) for changing various settings in the base unit A, and an operation unit 4 for outputting information on the setting change according to the operation. And a sub-control unit 5 that creates an instruction to change the setting in the master unit A based on the setting change information from the operation unit 4, and a signal from the sub-control unit 5 (for example, a wireless signal by infrared rays). The transmitter B is provided with the transmitter 6 for transmitting to the receiver 2. In this embodiment, as the environment detection unit 1, the base unit A includes a human body detection unit 1a that detects the presence or absence of a human body in the detection area, and a brightness detection unit 1b that detects the ambient brightness. ing.

In the human body detecting section 1a of this embodiment,
Although a pyroelectric element that detects heat rays emitted from the human body is used, the present invention is not limited to this, and as long as the presence or absence of the human body in the detection area can be detected, for example, an ultrasonic sensor or a sound sensor or A temperature sensor or a vibration sensor that detects movement of a person can be used. The brightness detection unit 1b also detects ambient brightness using a photoelectric conversion element such as a CdS element. The main control unit 3 has a CPU as a main component, and illuminates based on the detection information of the presence or absence of the human body in the detection area of the human body detection unit 1a and the detection information of the ambient brightness of the brightness detection unit 1b. Control of turning on / off or dimming of the device C is performed.

In the present embodiment, as shown in FIG. 2, the main unit A is integrally installed in the lighting fixture C which is a lighting load, and the slave unit B is configured as a portable remote control transmitter. There is. The operation unit 4 is provided on the surface of the body 10 of the child device B.
Is provided with an operation button 11. The lighting fixture C is installed on the ceiling, and the human body detection unit 1 is provided on the bottom of the fixture body.
a, a brightness detection unit 1b, and a reception unit 2 are provided.

Next, the operation of this embodiment will be described.
First, when the human body detection unit 1a detects the presence of a person in the detection area M, or when the known brightness detected by the brightness detection unit 1b is less than or equal to a threshold value, the main control unit 3 of the parent device A.
Sets the lighting fixture C in a predetermined lighting state set in advance (for example, 100% full lighting). On the other hand, the human body detection unit 1
When a does not detect the presence of a person in the detection area M, or when the ambient brightness detected by the brightness detection unit 1b is equal to or higher than a threshold value, the main control unit 3 of the parent device A presets the lighting fixture C. The predetermined lighting state (for example, extinguished) is set. When the human body detection unit 1a stops detecting the human body, the main control unit 3 returns the lighting fixture C to the original lighting state after a certain delay time has elapsed.

Here, the above various settings can be changed by using the slave unit B. Hereinafter, a method of making the change will be described. First, a case will be described in which the setting of the lighting state when lighting the lighting fixture C when the human body is detected in the detection area M and the lighting state when the human body is not detected is changed. When a predetermined operation button 11 included in the child device B is operated, the operation unit 4 outputs information on the setting change according to the operation of the operation button 11 to the sub control unit 5. This setting change information indicates the lighting level of the lighting fixture C (for example, 0% is off, 100% is all lighting), and the sub-control unit 5 sets the lighting fixture C to the lighting state based on the setting change information. A control command is created and transmitted from the transmission unit 6 as a wireless signal.

The receiving unit 2 of the main unit A installed in the luminaire C
Receives the wireless signal from the slave unit B, and the main control unit 3 puts the lighting fixture C into the lighting state according to the control command transmitted by the wireless signal. Then, the user sets the lighting device C.
The actual lighting state is confirmed, and when the desired lighting state is achieved, the setting is stored in the master unit A. This allows
After the human body detection unit 1a detects the human body next time, the main control unit 3 controls the lighting device C to the changed lighting state. Such a change of the lighting state can be performed in the same manner for the lighting state when lighting the lighting fixture C when the human body is detected and the lighting state when the human body is not detected. Also, the setting change between the lighting state when the ambient brightness detected by the brightness detection unit 1b is a predetermined value or less and the lighting state when the surrounding brightness is a predetermined value or more can be changed in the same manner as described above.

Next, a case will be described in which the above threshold value for the ambient brightness detected by the brightness detection unit 1b is changed. When a predetermined operation button 11 included in the child device B is operated, the operation unit 4 outputs information of setting change according to the operation to the sub control unit 5. The setting change information in this case indicates that the brightness detected by the brightness detection unit 1b at that time is stored in the main control unit 3 of the parent device A, and the sub-control unit 5 of the parent device A. A control command for causing the main control unit 3 to store the detection level of the brightness detection unit 1b is created, and the transmission unit 6 transmits it as a wireless signal. Then, from the next time, the stored detection level is processed as a threshold value. That is, the user may operate the child device B and perform the setting change operation when the surroundings reach the brightness at which the user wants to turn on the lighting device C.

Next, a case will be described in which the above-mentioned delay time from when the human body detection unit 1a stops detecting the human body until the main control unit 3 returns the lighting fixture C to the original lighting state. If a predetermined operation button 11 provided on the child device B is operated,
The operation unit 4 outputs information of setting change according to the operation to the sub control unit 5. The setting change information in this case indicates that the operation button 11 is being operated, and the sub control unit 5 indicates that the operation button 11 is being operated.
While the is being operated, the information to that effect is transmitted from the transmitter 6 by a wireless signal. By receiving the wireless signal from the child device B, the main control unit 3 of the parent device A obtains the operation time and the number of times the operation button 11 of the child device B is operated as the change information. Then, the main control unit 3 delays according to the operation time or the number of operations (for example, a value proportional to the operation time or the number of operations, or a value derived from these times or times based on a predetermined law). And change the setting.

The detection sensitivity of the human body detecting section 1a can be changed in the same manner as the above-mentioned change of the delay time. That is, the detection sensitivity is increased / decreased on the base unit A side according to the operation time and the number of operations of the operation button 11. Further, the detection area M can be similarly changed. For example, if the human body detection unit 1a uses an ultrasonic sensor, the detection area M can be expanded or narrowed by changing the angle of the horn, and a mechanism for rotating the human body detection unit 1a is provided. In other words, it is possible to change the direction of the detection area M.

Further, by operating the operation button 11 of the operation unit 4 of the child device B, the functions of the human body detecting unit 1a and the brightness detecting unit 1b may be switched on and off. That is, when the function of the human body detection unit 1a or the brightness detection unit 1b is turned off, the lighting device C is forcibly turned on by using, for example, the slave B regardless of the detection information.
It is possible to turn it off.

If a storage unit (memory or the like) for storing the above-mentioned various setting change contents is provided in the slave B, for example, the setting change read from the storage unit as shown in FIG. By transmitting the contents from the slave unit B to the plurality of lighting fixtures C by a wireless signal, the settings of the plurality of lighting fixtures C ... Can be changed to the same contents, or the changed contents can be stored in the storage means. The stored contents can be changed again.

As described above, according to the present embodiment, various settings in the lighting control device for controlling the lighting state of the lighting load C according to the state of the surrounding environment detected by the environment detection unit 1 and its change are set. Changes and the like can be easily performed using the child device B, and there is an advantage that usability is improved. In particular, it is effective when there is a high possibility that the purpose and requirements of using the lighting will change after installation.
