SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide a lighting system, And to save energy.

According to an aspect of the present invention, there is provided an automatic light control system including a main light sensor for generating a first illuminance value of light entering a room through a window or window, A second illuminance value generating unit that generates an ON signal for turning on illumination when the second illuminance value is higher than the first illuminance value by comparing the first illuminance value with a predetermined second illuminance value, A first control unit for generating an OFF signal for turning off the illumination when the ON signal is lower than a predetermined value; and a second control unit for turning on / off the illumination by receiving the ON / OFF signal, And a fourth illuminance value for illuminating the light illuminating the third illuminance value measurement area on the basis of the third illuminance value, The When the third illuminance value is smaller than the fourth illuminance value, the plurality of illumination units maintains the ON state, and when the third illuminance value is larger than the fourth illuminance value, an OFF signal for turning off the illumination is generated, And a second control unit for transmitting the fourth illuminance value to the illumination unit having the third illuminance value larger than the fourth illuminance value.

As described above, the present invention simplifies the configuration of the automatic lighting control system, increases the efficiency of system construction, minimizes hardware cost, and reduces cost, thereby saving energy efficiently.

2 is a diagram illustrating an example of generating a first illuminance value for turning on or off an illumination unit according to an embodiment of the present invention
FIG. 3 is a diagram illustrating an example in which the illumination of any one of the plurality of illumination units according to the embodiment of the present invention is turned off

Best Mode for Carrying Out the Invention Hereinafter, a configuration and an operation of a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a block diagram of an automatic lighting control system according to an embodiment of the present invention. Referring to FIG. 1, the automatic lighting control system includes a sensor unit 100, a first control unit 200, a plurality of illumination units 300, And a control unit 400.

More specifically, the main light intensity sensor unit 100 is installed near a window or window where light enters the room and generates a first illuminance value of the light that flows into the room.

For example, as shown in FIG. 2, the sensor unit 100 includes a first region where light is provided by the illumination 1, a second region where light is provided by the illumination 2, And generates the first daylight luminance value as a reference for determining whether to turn on or off the light up to the n-th region corresponding to the n-th light including the third region.

The first controller 200 compares the first illuminance value with a predetermined second illuminance value to generate an ON signal for turning on the illumination when the second illuminance value is higher than the first illuminance value, If the illuminance value is lower than the first illuminance value, an OFF signal for turning off the illumination is generated.

That is, the first controller 200 sets a second illuminance value for determining whether illuminance of light entering the window is turned on or off first.

Thereafter, the first controller 200 receives the main illuminance first illuminance value generated by the main illuminance illuminance sensor unit 100 and compares the first illuminance first illuminance value with the predetermined second illuminance value, thereby illuminating a plurality of illumination units 300 The illumination control unit generates an ON signal for turning on illumination when the second illumination intensity value is higher than the first illumination intensity value, OFF "

The plurality of illumination units 300 receive the ON and OFF signals to turn on or off the illumination, and at the same time turn on the illumination upon reception of the ON signal, the third illumination value of the region where the light is distributed by the illumination is measured And a sensing unit.

That is, when the ON signal is received, the plurality of illumination units 300 turn on the illumination because light of low illuminance comes in through the window to such a degree that it is difficult or difficult for work, life, activity, etc., If it is, it turns off the light because the light comes in through the window to the extent that work, life, activity is enough.

In particular, the sensing unit of the plurality of illumination units 300 measures the third illumination intensity value so as to turn off the lamp of the illumination unit if the illumination unit is not turned on.

In addition, the plurality of illumination units 300 continuously measure the sensing unit for measuring the third illuminance value at predetermined time intervals.

For example, as shown in FIG. 3, when the illumination units 1, 2, 3, and 4 are turned on and off, the illumination units 300, , The outdoor illumination value is assumed to be low, and the lighting units 1, 2, 3 and 4 are kept in the ON state under these conditions.

At this time, the illuminance value of the area 2 illuminating the illuminating unit 2 by the illuminating unit 1 and the illuminating unit 3 shown in FIG. 3 does not need to be turned on unless the illuminating unit 2 is turned on to such an extent that the illuminating unit 2 is turned on.

Therefore, the sensing part of the illuminating part 2 continuously measures the illuminance value with respect to the illuminated area of the illuminating part 2 and turns on or off to save energy.

The second controller 400 receives the third illuminance value and determines whether the fourth illuminance value is greater than the fourth illuminance value as the fourth illuminance value for illuminating the light illuminates the area where the third illuminance value is measured. If the third illuminance value is small, the plurality of illumination units are maintained in the ON state, and if the third illuminance value is larger than the fourth illuminance value, an OFF signal for turning off the illumination is generated. If the third illuminance value is larger than the fourth illuminance value To the illumination unit.

For example, the second controller 400 sets a predetermined fourth illuminance value to turn off the illumination unit 2 shown in FIG. 3, and compares the fourth illuminance value with the third illuminance value measured by the sensing unit of the illumination unit 2 If the third illuminance value is smaller than the fourth illuminance value, the plurality of illuminating units are maintained in the ON state. If the third illuminance value is larger than the fourth illuminance value, an OFF signal is generated and the third illuminance value To the large illuminating unit.

On the other hand, it is preferable that the second control unit 400 forcibly turns on or off the illumination of a plurality of illumination units by the user.

This is for manually controlling the lighting in case of bad weather, special work and construction.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It is not used to limit the scope.

Therefore, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
