DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting control device using a lighting device capable of dimming control.

[0002]

2. Description of the Related Art In recent years, the depth of a room has become deeper with the enlargement of a building. Due to the increase, artificial lighting for assisting daylighting in a room in the daytime is constantly turned on.

[0003] The daylight factor drops rapidly away from the window, and once it drops to a certain point, it gradually drops thereafter. For this reason, conventionally, in an office or a store, for example, artificial lighting is always lit at a place distant from a window to a certain extent. The brightness is controlled by measuring with a sensor and turning on or off the lighting or dimming based on the result. Further, such illumination control is generally performed using a dimming illumination device.

On the other hand, as is well known, the following ones have already been put to practical use as conventional illumination control devices using the above-described dimming illumination device. [1] Power phase control method (two-wire dimming lighting device) [2] Power phase control transmission method (two-wire dimming lighting device) [3] High-frequency constant current power source method (CT. [4] Time-division multiplexing control method (dedicated dimming terminal) [5] Method using a combination of timer, optical sensor and remote control relay (step dimming) [6] Method using dimmer (standard Switch box).

Next, these will be briefly described.
8 and 9 are block diagrams showing examples of a conventional lighting control device.

FIG. 8A shows a power supply phase control method (the above-described power supply phase control method).
This is a lighting control device using the dimming lighting device according to [1]). This lighting control device includes a control device 1 having a triac, a power supply unit 2, lighting circuits 3 and 3 ',
Lamps 4 and 4 '.

In the lighting control device configured as described above, the control device 1 controls the power supply means based on the dimming control signal u supplied from the dimming control signal supplying means constituted by an optical sensor or the like (not shown). 2, the AC waveform (power supply) supplied from 2 is subjected to phase control (for example, the voltage is dropped during the period indicated by t in the voltage waveform), and the amount of power supplied to the lighting circuits 3 and 3 ′ ( The dimming control for the lamps 4 and 4 'is performed by changing the integral value.

Next, FIG. 8B shows an illumination control device using a dimming illumination device according to the power supply phase control transmission method (the above [2]). The lighting control device comprises: a control device 6 having means for generating triac and phase control data;
It comprises power supply means 2, lighting circuits 5 and 5 ', and lamps 4 and 4'.

In the illumination control device configured as described above, the control device 6 controls the power supply means based on the dimming control signal u supplied from the dimming control signal supplying means constituted by an optical sensor or the like (not shown). Data (1100 in the figure) is generated depending on whether or not the phase of the AC waveform (power supply) supplied from 2 is controlled as shown in FIG. Then, the lighting circuits 5 and 5 'extract data from the supplied AC waveform (power supply), change the lighting frequency based on the data, and change the amount of power supplied to the lamps 4 and 4'. Light control for 4 and 4 'is performed. The generation of the phase control data is performed so that no loss occurs in the power supply voltage.

Next, FIG. 8C shows an illumination control device using a dimming illumination device based on a high-frequency constant current power supply system (the above [3]). This lighting control device includes a control device 7 including means for converting a frequency (high-frequency conversion) and means for maintaining an output current at a constant (predetermined value), a power supply means 2, and lighting circuits 3 and 3 '. , Lamps 4 and 4 ′.

In the lighting control device configured as described above, the control device 7 converts the frequency of the AC power supplied from the power supply means 2 to a high frequency of, for example, 40 kHz and includes an optical sensor (not shown). A current value is determined and output based on the dimming control signal u supplied from the dimming control signal supply means, and the power supply (constant current) is supplied to the lighting circuits 3 and 3 via the current transformers CT1 and CT2.
Supply. Thus, dimming control for the lamps 4 and 4 'is performed by controlling the amount of power supplied to the lamps 4 and 4'.

By the way, in the above-mentioned three types of lighting control devices, each of the control devices directly or indirectly controls the dimming, but also controls the power supplied to the lighting device (lamp) at the same time. . As a result, each of the control devices generates a considerable amount of heat, and the board structure must be taken. For this reason, there is a problem that each of the control devices (lighting control device) becomes large.

Next, FIG. 8D shows an illumination control device using a dimming illumination device according to the time division multiplex transmission control method (the above [4]). The lighting control device includes, for example, a control device 8 including a unit that generates control data 9 including a start bit, address data, and illuminance data; a power supply unit 2; a device address 11; Lighting circuit 12 having a function of processing
Signal line 10 connecting control device 8 and lighting circuit 12
And a lamp 4.

In the lighting control device configured as described above, the control device 8 is configured as shown in FIG. 1 based on a dimming control signal u supplied from a dimming control signal supply means constituted by an optical sensor or the like (not shown). The control data 9 as shown is generated and output to the signal line 10. Then, the lighting circuit 4 captures the control data 9 addressed to itself (device address) from the signal line 10, extracts the illuminance data from the control data 9, and changes the amount of power supplied to the lamp 4 based on the illuminance data. Thus, dimming control for the lamp 4 is performed.
A lighting circuit having a plurality of device addresses is connected to the signal line 10, and the control device 8 designates an address in the control data 9 output to the signal line 10 to control a desired lighting circuit. Dimming control can be performed.

However, in the illumination control device according to the above-mentioned method, a control function for dimming (for example, an operation of outputting a control signal) and a power control function for supplying power to the illumination device (lamp) are separately performed. . That is, the former function is provided to the control device, and the latter function is provided to the lighting circuit. For this reason, although the disadvantages of the above-described three-type lighting control device can be cleared, new means (functions) for time division multiplex transmission, that is, a main device for transmission, a terminal device, and the like are required.

Specifically, for example, it is necessary to provide the control device with a time-division multiplexing transmission function (communication function), and to provide the lighting circuit with a terminal function (communication function). This method is very advantageous for dimming control in a detailed area. However, as described above, for example, a time-division multiplex transmission function (communication function) is added to the control device and the lighting circuit.
Has to be added, and there is a disadvantage that the cost is increased.

Next, FIG. 9A shows a system using a combination of a timer, an optical sensor and a remote control relay (the above-described system)
An illumination control device using the dimming illumination device according to [5]). This lighting control device includes a power supply means 2, lighting circuits 13 and 13 'for performing three-stage dimming of, for example, 50%, 70%, and 100% of rated illuminance, lamps 4 and 4', illuminance And the light sensor 16 ′ that automatically designates one of the three-step light control according to the illuminance level, the light sensor controller 16, and the three-step light control of the three-step light control A remote control switch 17 for specifying one of them, a remote control relay 14 for switching the switch based on the specification of the optical sensor controller 16 or the remote control switch 17, and a transformer 15 for supplying power for opening and closing the remote control relay 14 And

In the lighting control device configured as described above, the remote control relay 14 closes, for example, a switch corresponding to the dimming level specified by the optical sensor controller 16 or the remote control switch 17 (user). . Thus, the lighting circuits 13 and 13 'supply the lamps 4 and 4' with an amount of power corresponding to the specified dimming level. Thus, step dimming control for the lamps 4 and 4 'is performed.

However, the lighting control device according to the above-described method requires a transformer, a remote control relay, and the like, and these devices are housed in a panel, which results in an increase in the size of the device. In addition, since the dimming is performed stepwise (stepwise dimming), there is a drawback that, in addition to the inability to finely adjust the illumination illuminance, it is not sufficient for fine energy saving.

Next, FIG. 9B shows an illumination control device using a dimming illumination device according to a dimmer system ([6]). This illumination control device, for example, changes the illumination illuminance designated by the user by the rotation angle of the volume dial to PM
It is composed of a dimmer 19 that converts and outputs a W signal, the power supply means 2, lighting circuits 18 and 18 ', and lamps 4 and 4'.

In the illumination control device configured as described above, when the user turns the volume dial of the dimmer 19 in order to obtain a desired (optimum) illumination illuminance, the rotation angle of the volume dial corresponds to the rotation angle of the volume dial. The PWM signal is supplied to the lighting circuits 18 and 18 ', respectively. The lighting circuits 18 and 18 'change the amount of power supplied to the lamps 4 and 4' based on the input PMW signal, thereby performing dimming control.

However, the lighting control device according to the above-described method mainly performs the dimming control manually, and has a drawback that the operation is difficult in order to perform an energy saving effect and a comfortable dimming control for the user. is there.

[0023]

As described above, in the conventional lighting control device, it is not possible to obtain a sufficient energy saving effect due to stepwise dimming, or the workability is poor due to the panel structure, and the device becomes large. There has been a problem (defect) that the cost tends to increase if the apparatus configuration can be reduced in size.

An object of the present invention is to provide a lighting control device having a small control device.

[0025]

According to a first aspect of the present invention, there is provided at least one light sensor for detecting an illuminance level; one or more light controllable lighting devices; and a display unit disposed on the front side. And a housing connected to a dimming signal output unit disposed on the back side, and configured to be attachable to a standard switch box; and a power supply unit, and a dimming level of the lighting device.
