Description

  The present invention relates to an illumination control device that controls lighting, extinction, brightness, and the like of a lighting fixture based on detection values and external signals of a human sensor and an illuminance sensor, an illumination device including the illumination control device, and a plurality of illuminations The present invention relates to an illumination control system including a control device and an illumination system including the illumination control system.

  In the conventional lighting control device, when the human sensor detects a human body and no external signal is input, the light source of the light source is based on the detection value of the illuminance sensor so that the illuminance of the irradiated surface is within the target illuminance range. The light output is controlled. On the other hand, when an external signal is input, the lighting control device ignores the control by the illuminance sensor and the human sensor, and the lighting state determined in advance according to the priority set in the input external signal (For example, refer to Patent Document 1).

Japanese Patent Laid-Open No. 10-302969 ([0018] to [0020], FIG. 1)

By the way, in the fluorescent lamp constituting the lighting fixture, the electron emitting material applied to the electrode is consumed at the time of starting, and therefore the lamp life is generally shortened as the number of blinks increases. For example, if the fluorescent lamp is blinked 20 to 30 times a day, the lifetime is halved compared to the case where the fluorescent lamp is not blinked once. However, it goes without saying that it is cheaper to turn off the fluorescent lamp when no people are present. On the other hand, when the fluorescent lamp is dimmed, there is no effect on the lamp life, but if the dimming rate is 25%, power consumption is 35% when the dimming rate is 100%. Here, the dimming rate means the degree of brightness when the brightness when the fluorescent lamp is turned on is 100%. When the dimming rate is 70%, the degree of brightness of the fluorescent lamp. Means 70%. Hereinafter, the extension of the lamp life of the fluorescent lamp and the reduction of power consumption will be referred to as energy saving.
In the above-described conventional lighting control device, no consideration is given to energy saving.

  On the other hand, the sensation felt by a person by blinking or dimming a fluorescent lamp is different as shown below even within the same building. That is, it is necessary to provide a plurality of lighting control devices in areas such as corridors and stairs where the area to be illuminated is wider than the detection areas of the human sensor and the illuminance sensor. In this case, the above-described conventional illumination control device does not exchange any signal between adjacent devices. Therefore, in each illumination control device, each time the human sensor enters the human body non-detection state or the human body detection state, the illumination is performed. The lighting, extinguishing, brightness, etc. of the appliance will be controlled. That is, as the person passes, the luminaires are sequentially turned on in the area where the person is traveling, and the luminaires are sequentially turned off in the area where the person has passed. As a result, people passing through the corridors and stairs feel uncomfortable, such as anxiety, loneliness, and alienation.

  In addition, people do not stay for a long time compared to other places such as toilets, smoking corners, hot water supply rooms, etc., and people are relatively small and places where ventilation fans are provided for deodorization and ventilation. If the fluorescent lamp is turned off when a person enters the area without any light, the above-mentioned feeling of incongruity is felt. Even if the light is dimmed and the illuminance is returned to the minimum illuminance as soon as there are no people, the above-mentioned uncomfortable feeling is not felt. In addition, odors, carbon dioxide based on human breath and gas combustion, etc. remain in the area for a while even if no one is present. Therefore, it is necessary to operate the ventilation fan for a while even if there are no people, but the conventional lighting control device described above does not have a function of outputting the detection value of the human sensor to the outside, It is necessary to provide a human sensor and a timer, or separately provide a relay control terminal that converts a dimming signal from the lighting control device into a signal for turning on / off the relay.

  In addition, in places where customers temporarily arrive, such as corporate reception desks, customer entrances, customer elevator halls, etc., it is necessary to keep the lights lit even during the working hours even if there is no person such as a receptionist. is there. The reason is that when a customer visits, if the lights are turned off at this kind of location, the customer will not get a good impression, such as thinking that the company is closed or not active. It is. On the other hand, before and after working hours, in order to save energy, the fluorescent lamp should be dimmed to the minimum illuminance when no one is present and dimmed to an appropriate illuminance when one arrives. However, the above-described conventional lighting control device cannot meet such a demand because it does not have a function of controlling the validity / invalidity of the human sensor according to time as well as energy saving.

  In addition, the illuminance sensor that constitutes the illumination control device detects the average illuminance in the detection area (the target is the floor surface or the desk surface). When exposed to direct sunlight such as, the illuminance of the direct sunlight is extremely high (for example, about 15,000 lux or more), so the average illuminance in the detection area of the illuminance sensor is also high. As a result, the lighting control device lowers the dimming rate of the lighting as the window closes, and only the desk surface near the window where the floor surface is bright but not exposed to the sun is extremely dark. Therefore, in the past, it was recommended that the blinds attached to the windows be closed and used during times of direct sunlight, but this would be cumbersome for the user and the meaning of providing a lighting control device. Cut in half.

  The present invention has been made in order to solve the above-described problems, and an object of the present invention is to provide a lighting control device capable of improving human sense (comfort) with respect to lighting dimming while saving energy. , A lighting device, a lighting control system, and a lighting system.

  The lighting control device according to the present invention turns on / off a lighting fixture based on a human body detection signal from a human sensor that detects presence or absence of a human body and a detection value from an illuminance sensor that detects illuminance in a detection area. Output operation mode 1 for controlling the brightness and outputting a value indicating the human body detection state or a value obtained by extending the value indicating the human body detection state by the holding time, in the human body detection state Output operation mode 2 for outputting a value obtained by extending a value indicating a certain amount by a delay time or a value obtained by extending a value indicating a human body detection state by a delay time and a holding time; Output operation mode 3 in which the first value is output when it is higher than the set first threshold value, and the second value is output when it is lower than the first threshold value, and the detection value from the illuminance sensor is Pre-set second Output operation mode 4 in which the first value is output when the threshold value is higher than the threshold value, and the second value is output when the threshold value is lower than the second threshold value. The analog voltage value obtained by converting the dimming signal to be output is At least one operation mode is an output operation mode 5 for outputting, an output operation mode 6 for outputting an analog voltage value obtained by converting a detection value from an illuminance sensor, or an output operation mode 7 for outputting an external signal as it is or after signal processing. It is configured to be executable and selectable.

  According to the present invention, by selecting an output operation mode in accordance with an area where a lighting fixture is installed, it is possible to improve human sense (comfort) with respect to lighting dimming while saving energy.

Specifically, the human sensor 2 can detect, for example, a hand movement of about 30 cm at a distance of 2 m. When the human sensor 2 is attached to a ceiling with a height of 2.5 m, the detection area is directly below it. It is a quadrangular pyramid shape having a rectangular shape of about 5 m × 7 m centered on the floor surface and having the human sensor 2 as a vertex.

The illuminance sensor 3 detects the average illuminance in the detection area (the target is the floor surface or the desk surface) and supplies a detection value D _L (0 to 5 V), which is a voltage value corresponding to the average illuminance, to the illumination control device 1. To do. When attached to a ceiling with a height of 2 m, the detection area has a conical shape with a circle having a diameter of about 4 m centered on the floor surface immediately below the bottom surface and the illuminance sensor 3 as a vertex. The illuminance sensor 3 is, for example, a photoelectric conversion element such as a photodiode or a phototransistor having a light receiving sensitivity that detects brightness with a sensitivity close to human eyes, and light from any position in the detection area is substantially equal.

In the case of collectively each luminaire 4 ₁ to 4 _n are simply referred to as a lighting fixture 4. The illumination remote controller 5 is used when an operator performs various setting operations for illumination control, and supplies an infrared command signal _SCI corresponding to the operation to the illumination control device 1.

The output buffer 25 includes the photocoupler and the like, and performs noise removal and waveform shaping of the output signal.

  When a certain input / output terminal 16 is set to the input operation mode, the external input / output unit 11 receives an “L” level from an output port corresponding to the input port of the control unit 12 so as not to adversely affect the input port side. And an external signal supplied from the input / output terminal 16 is read and supplied to the control unit 12. On the other hand, when a certain input / output terminal 16 is set to the output operation mode, the external input / output unit 11 causes the output buffer 25 to receive information of “H” level or “L” level supplied from the output port of the control unit 12. To the input / output terminal 16 and to monitor the state change of the input / output terminal 16, the state change of the input / output terminal 16 is supplied to the input port of the control unit 12 via the input buffer 24.

To form a private room. As shown in FIG. 8, the human sensor 2 has the entire private room as a detection area 46.

Next, the operation of the illumination device having the above configuration will be described with reference to FIG. In the lighting control device 1, input-output and the terminal 16 ₁ is set to output operation mode 2, the order retention time T _K (e.g., 3 minutes) and the delay time T _D (e.g., 5 minutes) is preset Has been. Further, in the lighting control device 1 controls the dimming signal output unit 13, the value of the human body detection signal S _H from the human sensor 2 connected to the self, a value indicating a human body detecting state (e.g., "H" level) when it is, along to output the dimming signal S _CL indicating a 70% dimming ratio, a value indicative of the human body non-detection state (e.g., "L" level) in some cases, to output the dimming signal S _CL indicating a 0% dimming ratio.

First, since the human sensor 2 connected to the illumination control device 1 does not detect a person in the initial state, the illumination control device 1 controls the dimming signal output unit 13 to adjust the dimming rate to 0%. A dimming signal _SCL indicating is output. Accordingly, the two lighting fixtures 4 shown in FIG. 6 are both turned off. In such a state, at time t ₁ shown in FIG. 9, as shown in FIG. 8, a person enters the private room and sits on the Western-style toilet 43 and is connected to the lighting control device 1. Is in the detection area 46.

Thus, the human sensor 2, compared lighting control apparatus 1, a value indicative of the human body detection state (in this example, "H" level) to supply the human body detection signal S _H (FIG. 9 (a) Therefore, the illumination control device 1 controls the dimming signal output unit 13 to output the dimming signal _SCL corresponding to the dimming rate of 70% shown in FIG. 9B. Moreover, since the output operation mode 2 is set for the input / output terminal 16 ₁ , the lighting control device 1 is connected to the ventilation fan 41 from the input / output terminal 16 ₁ as shown in FIG. A value _SHO having a value indicating the detection state (in this example, “H” level) is supplied. The ventilation fan 41 supplied with the “H” level value S _HO drives a motor (not shown) to rotate a fan (not shown), thereby exhausting carbon dioxide or the like based on odors in the individual room or human breath. Start.

Next, at time t ₂ , it is assumed that a person has finished using the door, opens the door 45, and exits the private room, thereby exiting from the detection area 46 of the human sensor 2 connected to the lighting control device 1. Thus, the human sensor 2, compared lighting control device 1, the human body the value (in this example, "L" level) indicating the non-detection state human body detection signal S _H for supplying (FIG. 9 (a in )reference). However, since the holding time T _K has not elapsed, the illumination control device 1 controls the dimming signal output unit 13 to _generate the dimming signal S _CL corresponding to the dimming rate of 70% shown in FIG. together continues to output, for the input and output terminal 16 ₁ that is set and the output operation mode 2 for ventilators 41 from the input and output terminals 16 _1, as shown in FIG. 9 (c), "H" level Continue to supply the value _SHO .

Next, since the holding time T _K has elapsed at the time t ₃ , the lighting control device 1 controls the dimming signal output unit 13 to adjust the dimming rate as shown in FIG. 9B. to output the dimming signal S _CL to vary from the rate of 70% to 0% dimming rate with (fade-out), output the terminal 16 ₁ is set the output operation mode 2, the delay time T _D has passed not so with respect ventilators 41 from the input and output terminals 16 _1, as shown in FIG. 9 (c), continues to supply "H" level of the value S _HO. The time required for fading out is, for example, about 0.1 second. Next, the lighting control device 1, at time t _4, the input and output terminal 16 ₁ is set the output operation mode 2, since the delay time T _D has elapsed, to ventilators 41 from the input and output terminals 16 ₁ Then, as shown in FIG. 9C, an “L” level value S _HO is supplied. The ventilation fan 41 supplied with the “L” level value S _HO stops the rotation of the fan (not shown) by stopping the driving of the motor (not shown), and the carbon dioxide based on the odor in the individual room or the breath of the person. Stop exhausting.

Thus, according to the configuration of this example, the lighting control device 1 of this example is relatively narrow without a person staying for a long time compared to other places such as a toilet, a smoking corner, a hot water supply room, etc. While providing in the location where the ventilation fan is provided for deodorization, ventilation, etc., the input / output terminal 161 of the illumination control apparatus ₁ and the ventilation fan 41 are connected. Further, the output operation mode 2 is set for the input / output terminal 16 ₁ .

Therefore, forgetting to turn off the luminaire 4 and the ventilation fan 41 can be prevented and energy saving can be achieved, and the human sense (comfort) with respect to lighting dimming can be improved. Thereby, it is not necessary to provide a human sensor and a timer dedicated to the ventilation fan 41 as in the prior art. Incidentally, by using a relay which is externally performs power on / off of the ventilation fan 41, when configured to use a general-purpose remote control relay, the input and output terminal 16 ₁ is output operation mode 2 is set If, may output a set pulse and a reset pulse from the output terminal 16 _1.

Timer 64, the window 62 ₁ direct sunlight shine in time by the afternoon sun from (e.g., 3:00 o'clock to 5:00 o'clock) time arrival signal S _T of only the "H" level via the input and output signal lines 65 ₁ To the lighting control device 1a. In FIG. 14, direct sunlight 66a is around 0:00 pm, direct sunlight 66b is around 3:00 pm, and direct sunlight 66c is around 5:00 pm.

Further, each lighting control device 1a~1d, as shown in FIG. 14, are connected to each other via the input and output signal lines 65 ₂ to 65 _4. That is, the input-output terminal 16 ₂ of the lighting control apparatus 1a and the output terminal 16 ₁ of the lighting control device 1b is connected via the input and output signal lines 65 _2, input-output terminals 16 ₂ and the illumination control of the lighting control device 1b input-output terminal 16 ₁ of the apparatus 1c is connected via the input and output signal lines 65 _3, the lighting control apparatus 1c of the input and output terminals 16 ₂ and the lighting control apparatus 1d of the input and output terminals 16 ₁ and the input and output signal lines 65 Connected through _four .

Next, the operation of the illumination system having the above configuration will be described. The lighting control device 1a, input-output terminals 16 ₁ Input Mode 4 for is set the output operation mode 7 for input and output terminal 16 _2. That is, the lighting control device 1a, when the time reaches the signal S _T from the timer 64 is supplied via the input and output signal lines 65 ₁ and the input-output terminal 16 ₁ is at the "H" level, forcibly illuminance sensor The detection value D _L (0 to 5 V) from 3a is set to invalid. Moreover, since it is set the output operation mode 7 for input and output terminals 16 _2, the lighting control device 1a, as such or amplification and waveform shaping, etc. signals the supplied time arrival signal S _T from the input and output terminals 16 ₁ Is supplied from the input / output terminal 16 ₂ to the illumination control device 1b via the input / output signal line 65 ₂ .

On the other hand, the other lighting control apparatus 1 b to 1 d, the input and output terminal 16 ₁ is input operation mode 4, the input-output terminal 16 ₂ is set the output operation mode 7. That is, when the lighting control device 1 adjacent the input and output signal lines 65 ₂ to 65 ₄ times reaching signal S _T supplied via the "H" level, the lighting control device 1b~1d forcibly In addition, the detection value D _L (0 to 5 V) from the illuminance sensors 3 b to 3 d is set to be invalid. Moreover, since it is set the output operation mode 7 for input and output terminals 16 _2, each lighting control device 1b~1d is directly or amplification and waveform shaping time arrival signal S _T supplied from the output terminal 16 ₁ Are supplied from the input / output terminal 16 ₂ to the adjacent lighting control device 1 via the input / output signal lines 65 ₃ and 65 ₄ .

Furthermore, in the lighting control apparatus 1 a to 1 d, by controlling the dimming signal output unit 13, the value of the human body detection signal S _H from the human sensor 2 connected to the self, that the human body detecting state When the value is a value (for example, “H” level), a dimming signal S _CL indicating a dimming rate of 70% is output, and a value (for example, the “L” level indicating that the human body is not detected) If) in which to output the dimming signal S _CL indicating a 0% dimming ratio. Further, in the lighting control device 1 a to 1 d, after the holding time T _K controls the dimming signal output unit 13 to output the dimming signal S _CL indicating a 50% dimming ratio.

First, in the initial state before the working hours of the company (9 am), the human sensors 2a to 2d connected to the respective lighting control devices 1a to 1d do not detect a person, and the timer 64 "H" for the time arrival signal S _T of the level is not supplied, the lighting control device 1a~1d controls the dimming signal output unit 13, a dimming signal S _CL indicating a 0% dimming ratio Output. Accordingly, a total of 48 lighting fixtures 4 partially shown in FIGS. 13 and 14 are turned off. In such a state, it is just before working hours (9:00 am), people enter one of the working area blocks in the working area, and the human sensors 2a to 2d connected to the lighting control devices 1a to 1d Suppose that you entered the detection area.

Thus, each person detecting sensor 2a~2d are for the corresponding lighting control device 1 a to 1 d, a value (in this example, "H" level) indicating that the human body detection state supplies a human body detection signal S _H for since, the illumination control unit 1a~1d controls the dimming signal output unit 13 to output the dimming signal S _CL corresponding to the dimmer rate 70%.
