1 is a schematic configuration diagram of a lighting control system according to an embodiment of the present invention.

Referring to FIG. 1, a lighting control system 100 according to an exemplary embodiment of the present invention includes a lighting control panel 110 that receives lighting control input from a user and generates data, An individual control module 120 for outputting a control signal for controlling the power supply of the SMPS that supplies power to the respective lights 10, and an SMPS 130 for supplying power to the respective lights 10. [

According to the embodiments of the present invention, the illumination described throughout the specification and the drawings is generally an apparatus for illuminating the back using electricity. In addition to general illumination such as fluorescent lamps, incandescent lamps, lamps, etc., illumination devices such as LED lights, . And the SMPS can include devices such as ballasts.

The individual control module 120 and the SMPS 130 are separately provided in each of the n lights 10. The n individual control modules 120 are connected to the first individual control module 120 through the communication line 11, The first individual control module 120 is connected to the illumination control panel 110 so that the data transmitted from the illumination control panel 110 through the communication line 11 is first Are sequentially transmitted in series from the individual control modules 120 and are all received by the individual control modules 120. [

The communication applied to the individual control module 120 and the illumination control panel 110 can be applied to any communication method as long as the communication method can be serialized. When the communication method is determined, 110 and the illumination control panel, respectively. Also, it is preferable that a cable supporting the communication method defined above is applied to the communication line 11 as well.

The lighting control panel 110 is a panel for receiving user's control input for n lights 10 installed inside or outside the building. The lighting control panel 110 includes an input button for selecting a desired lighting, And a button for controlling the brightness of the selected illumination.

The present invention is not limited to the embodiment of the present invention. In other embodiments, a button for controlling other items of the illumination 10 may be additionally provided.

When the illumination control panel 110 receives the illumination selection input from the user and receives the illumination control input, it generates data for controlling each illumination 10. [

The lighting control panel 110 may receive at least one illumination 10 of n lights 10 to be controlled. At this time, according to the button configuration of the illumination control panel, Select some of the lights 10 grouped according to a certain criterion, or select individual lights 10.

For example, the "all" button is provided on the illumination control panel 110 to select all of the n lights 10, and each illumination number button is separately provided from the light 1 to the n lights, Individual lights 10 may also be selected.

In the case of a button for selecting the grouped illumination 10, for example, there are buttons divided into a first floor, a second floor and a third floor so that they can be selected by the floor or divided into one line, two lines and three lines There is also a button, which allows you to choose on a line-by-line basis.

That is, the configuration of the buttons may be differently configured according to the lighting installation configuration where the lighting control system 100 is applied and the convenience of the user.

Also, a numeric keypad is provided on the illumination control panel 110 as shown in FIG. 1, so that the user can directly input the number of the illumination.

If you want to turn on the light 2 as in the example shown in Fig. 1, you can enter 02 on the numeric keypad.

The illumination control panel 110 may include a display window for displaying input contents to display the input illumination 10. [

As shown in FIG. 1, the number of lights input on the numeric keypad may be displayed, or the selected light may be displayed by all / some / individual buttons. For example, when the "ALL" button is selected, "ALL" 3-line "when the" 1st floor "button is selected," 3-line "if the 3rd line is selected, and" 4th floor hallway " have.

Alternatively, the location of the light 10 installed in the building may be displayed as a map on the display window, and the location may be displayed in a specific color or shape at a location corresponding to the selected light 10, or may be indicated by blinking, And the like.

The lighting control panel 110 having such a display function not only displays the selected input light 10, but also displays contents of the ON / OFF control input and the brightness control input, .

When the user selects and inputs the illumination 10 desired to be controlled by the illumination control panel 110, the illumination control panel 110 generates illumination identifier data for the illumination.

The illumination identifier data is data to be transmitted to each individual control module 120 through the communication line 11 to identify each of the individual control modules 120 and the corresponding illumination 10.

The n individual control modules 120 corresponding to the n lights 10 receive all the data transmitted from the illumination control panel 110 through the communication line 11, It is necessary to output a control signal for controlling the light 10.

That is, it is possible to determine the validity of the data received from each individual control module 120 through the illumination identifier data.

Accordingly, the illumination control panel 110 generates illumination identifier data, which is pre-allocated to the illumination, when the user selects the illumination 10 to be controlled. When the individual control module 120 receives the illumination identifier data, So that it can be identified.

When the light 10 to be controlled is selected through the illumination control panel 110, the user inputs whether to turn on or off the selected light.

Although the ON button and the OFF button are provided in FIG. 1, in other embodiments, the ON and OFF can be selected by a toggle switch or the like instead of a button, and ON or OFF can be inputted in other ways.

When ON or OFF is inputted, the illumination control panel 110 generates corresponding illumination ON / OFF data and transmits it to the n individual control modules 120 through the communication line 11 together with the previously generated illumination identifier data do.

The illumination identifier data and the illumination ON / OFF data from the first individual control module 120 to the nth individual control module 120 are transmitted along the communication line 11 connected in series and all data is transmitted to each individual control module 120 The individual control module 120 first compares the illumination identifier data with the previously stored identifier data.

Each of the individual control modules 120 previously stores the identifier data agreed with the illumination control panel 110 in advance, and controls the lighting control panel 110 so that the illumination ON / OFF data received from the illumination control panel 110 is illuminated If the identifier data is matched with the previously stored identifier data, the control signal is output using the illumination ON / OFF data.

If the illumination ON / OFF data indicates that the illumination is to be turned on, an ON control signal for controlling the SMPS 130 to output power for the illumination 10 is output. If the illumination ON / OFF data is data for turning off the illumination, 13 to release the supply of the power for the illumination 10. [

Such illumination identifier data and illumination ON / OFF data may be composed of digital data such as the following examples.

The illumination identifier data is composed of binary data having bits equal to or greater than the number of lights 10, each bit being configured to be an identifier indicating a respective illumination 10, and the illumination ON / Data is composed of data of the same length as the data, and each bit is an identifier for judging ON / OFF of each of the lights 10, so that ON / OFF can be distinguished by "1" or "0".

For example, when the number of lights 10 is four, the illumination identifier data is composed of data having a total length of 4 bits, and four bits from the left to the bottom correspond to the fourth illumination from the first illumination, When the illumination is selected in the illumination control panel 110, a bit corresponding to the selected illumination is generated as "1 ", and a bit corresponding to the unselected illumination is configured as" 0 ".

If the second illumination and the fourth illumination are selected, the illumination identifier data is generated as "0101 ".

If ON is input for the second illumination and the fourth illumination in the illumination control panel 110, the illumination ON / OFF data is generated as "0101 & .

When the generated data is transmitted to the individual control module 120, the individual control module 120 first compares the illumination identifier data with the previously stored identifier data. In the individual control module 120 corresponding to the second illumination, 0100 "data of the preset identifier data and" 0101 "of the received illumination identifier data to determine whether the result is " 0100"

In the individual control module 120 corresponding to the third illumination, the previously set identifier data is set to "0010 ", an AND operation is performed with the received illumination identifier data" 0101 ", and it is determined whether the result is "0010 & Since the result of the operation is "0000", it does not match, and the control signal is not output to the SMPS without considering the illumination ON / OFF data.

That is, it is determined whether or not the illumination identifier data is matched through logic operation using the preset identifier data as the mask data, and whether the illumination ON / OFF data is ON or OFF is determined by using the pre-stored mask data.

In order to perform this process, it is preferable that a control module capable of performing such comparison and calculation processing is configured in the individual control module 120. For example, a microcontroller or a chip such as a DSP (Digital Signal Processor) may be applied.

This is merely an example of generating data in accordance with an embodiment of the present invention, and in another embodiment the lighting control panel 110 may generate lighting identifier data and lighting ON / OFF data in other manners.

The individual control module 120 determines whether data is valid in the individual control module 120 using the illumination identifier data. When it is determined that the data is valid, the individual control module 120 supplies power to the illumination 10 using the illumination ON / OFF data OFF control signal to the SMPS 130 to control ON / OFF of the illumination 10. [

The lighting control panel 110 also generates lighting brightness data as well as lighting ON / OFF data.

When the selection of the illumination 10 desired to be controlled in brightness is input in the illumination control panel 110 and the illumination identifier data is generated, the user uses the illumination brightness control button provided in the illumination control panel 110 to adjust the brightness .

The illumination brightness control button may include, for example, an up button and a down button. When the up button is pressed once, the brightness of the current illumination can be increased by a predetermined level, and the brightness level is increased by the number of times pressed.

Such a light brightness control input method is not limited to the present embodiment, but may be input in other ways in other embodiments.

The illumination control panel 110 generates illumination brightness data according to the input brightness and transmits the illumination brightness data to the individual control module 120 through the communication line 11 together with the illumination identifier data.

The individual control module 120 compares the illumination identifier data with predetermined identifier data to determine whether the illumination identifier data is valid. If it is determined that the illumination identifier data is valid, the individual control module 120 outputs the brightness control signal corresponding to the illumination brightness data to the SMPS 130, .

At this time, the brightness control signal output from the individual control module 120 can control the brightness of the illumination 10 by controlling the power level of the SMPS 130.

The illumination brightness data generated by the illumination control panel 110 can be displayed, for example, as binary data. If data having a 4-bit length is set as an example, the left first bit determines whether to raise (1) or fall Bits, and the remaining three bits can represent the up and down steps.

For example, if the user presses the up button of the light control panel 110 twice, the light brightness data generated by the light control panel 110 is "1010 ", and if the up button is pressed three times, 1011 ".

The individual control module 120 receiving the illumination brightness data determines that the brightness is increased through the first left bit and determines the up phase through the remaining three bits. If the brightness is increased by three stages, And outputs a brightness control signal to the SMPS 130 so that the power corresponding to the three-step brightness up can be output.

When the individual control module 120 outputs the illumination ON / OFF control signal or the illumination brightness control signal, the SMPS 130 outputs or cuts off power to the illumination 10 according to the input control signal.

The SMPS 130 receives AC power and outputs a DC power capable of driving the lamp 10. At this time, the SMPS 130 controls the output / cutoff of the DC power supply in response to the illumination ON / OFF control signal, Thereby controlling the power supply level of the direct current power and outputting it to the illumination 10. [

The SMPS 130 may include an individual control module 120 in its housing, or each individual control module 120 and the SMPS 130 may be integrated. It is connected to a separate power line for AC power supply.

The AC power lines may be connected in series between the SMPSs 130 in the same manner as the communication lines 11 connecting the individual control modules 120 in series so that alternating currents are supplied in series. In this case, when the individual control module 120 is configured in the housing of the SMPS 130 and the power line communication is performed through the AC power line connecting the SMPS 130 in series, a separate communication line 11 is not formed Serial communication between the individual control modules 120 becomes possible.

 1, if the n individual control modules 120 and the SMPSs 130 corresponding to the individual control modules 120 are constituted by a single housing and the AC power lines are connected in the same manner as the communication lines 11, Data can be communicated in the lighting control panel 110 to each individual control module 120 and AC power can also be supplied to each SMPS 130 so that the cable connection configuration of the lighting control system 100 is much simpler .

The configuration of the lighting control panel 110 in the lighting control system 100 will be described in more detail.

In the example of FIG. 2, a step button is selected in the one-touch input unit 111, and a step is displayed on the display unit 114. FIG.

The user can select the illumination through the one-touch input unit 111 but also through the number input unit 112. [

When it is difficult to display all individual lights with one-touch input unit because of a large number of lights, if the number of the preset illumination is inputted through the number input unit 112, the corresponding illumination can be individually selected.

In the example of FIG. 2, the number input unit 112 is configured in the form of a keypad, and a user can input a number of a known illumination and control the corresponding illumination.

When the lighting 10 desired to be controlled is selected through the one-touch input unit 111 or the number input unit 112, it is input through the illumination ON / OFF input unit 113 whether the selected illumination 10 is to be turned ON or OFF.

The display unit 114 similarly displays the result input through the illumination ON / OFF input unit 113. After ON / OFF of the illumination 10 desired to be controlled is selected, the data generation unit of the illumination control panel 110 Generates illumination identifier data corresponding to the input illumination 10 and illumination ON / OFF data corresponding to the input ON / OFF, and transmits the illumination ON / OFF data to the individual control module 120 through the communication unit.

When the user selects the illumination 10 to be controlled through the one-touch input unit 111 or the number input unit 112 and then selects the brightness of the illumination 10 to be increased or decreased through the illumination brightness input unit 115, The controller generates the illumination identifier data corresponding to the input illumination 10 and the illumination brightness data corresponding to the input illumination brightness up / down and transmits the data to the individual control module 120 through the communication unit.

The lighting control panel 110 may be attached to a wall or provided at a specific place, but may be configured in the form of a remote control.

That is, the one-touch input unit 111, the number input unit 112, the illumination ON / OFF input unit 113, and the illumination brightness input unit 115 are configured in the form of a wireless remote controller, and the display unit 114, And transmits the result inputted to the main device through the short distance communication or infrared communication from the wireless remote controller, the main device receives the result, displays it on the display part 114 and generates data, and controls the individual control module 120 ) To be transmitted.

In addition, by applying such a remote control method, instead of the wireless remote controller, a light is selected through a separate application in a portable terminal of a user, and ON / OFF and brightness are input, the result input to the main device is transmitted through a communication network, So that the light 10 can be controlled.

That is, the input device included in the illumination control panel 110 can be implemented as any device that can receive a user's input, such as a remote control, a portable terminal, a personal computer, etc., and transmit the input through communication.

When data is generated according to a user's input in the illumination control panel 110, the generated data is transmitted to the individual control modules 120 connected in series through the communication line 11, and data validity is determined, The control signal is outputted to the SMPS 130 corresponding to each individual control module 120 and the illumination 10 is controlled according to the power control of the SMPS 130.

The detailed configuration of the individual control module 120 will be described in more detail.

3 is a schematic block diagram of an individual control module of a lighting control system according to an embodiment of the present invention.

3, the individual control module 120 according to an exemplary embodiment of the present invention includes a communication unit 121, a data analysis unit 122, and a control unit 123.

The communication unit 121 receives the illumination identifier data, the illumination ON / OFF data, and the illumination brightness data from the illumination control panel 110 or the previous individual control module 120 connected in series, To transmit the received data again.

For example, in the case where the individual control module 120 is provided in the housing of the SMPS 130, when the AC power is supplied to the SMPS 130, It is possible to perform power line communication using the power line. Therefore, the communication unit 121 preferably applies a device for performing power line communication.

The data analyzer 122 then receives the illumination ON / OFF data or the illumination brightness data from the individual control module 121, and transmits the illumination ON / OFF data or the illumination brightness data to the corresponding control module And analyzes whether it is valid data through the illumination identifier data.

The data analyzer 122 compares the stored illumination identifier data with the stored illumination identifier data, that is, the identifier data previously set and stored so as to be differently assigned to each individual control module, The received illumination ON / OFF data or illumination brightness data is determined to be valid data for the corresponding individual control module.

After the data analysis unit 122 determines that the illumination ON / OFF data or the illumination brightness data is valid data, the control unit 123 can turn ON / OFF the power output of the SMPS 130 according to the illumination ON / OFF data And outputs a brightness control signal for controlling the brightness of the light 10 by controlling the power supply level of the SMPS 130 according to the brightness data of the light.

The ON / OFF control signal or brightness control signal output through the control unit 123 is input to the SMPS 130 corresponding to the individual control module 120 to supply / block the power supplied to the illumination 10, The brightness of the light 10 can be raised or lowered through the level of the light.

Hereinafter, a lighting control method using the lighting control system 100 will be described in detail.

4 is a flowchart of a lighting control method according to an embodiment of the present invention.

Referring to FIG. 4, at least one light 10 desired to be controlled among the n lights 10 is input to the lighting control panel 110 (S101). When the lighting 10 desired to be controlled is selected through the one-touch input unit 111 or the number input unit 112 of the lighting control panel 110, the user selects whether to turn on or off the next selected lighting 10 (S103 ).

The input result is displayed on the display unit 114 of the illumination control panel 110.

Next, the illumination control panel 110 generates the illumination identifier data corresponding to the illumination 10 selected and input through the one-touch input unit 111 or the number input unit 112, and generates illumination identifier data corresponding to the ON control input or the illumination corresponding to the OFF control input ON / OFF data is generated (S105).

Next, the lighting control panel 110 transmits the generated lighting identifier data and lighting ON / OFF data to the first individual control module 120 through the communication line 11 (S107).

When the first individual control module 120 receives the light identifier data and the illumination ON / OFF data, it transmits the data to the individual control module 120 connected in series via the communication line 11 and connected in series by this transmission method the illumination identifier data and the illumination ON / OFF data are sequentially transmitted to the nth individual control module 120 (S109).

The n individual control modules 120 receiving the illumination identifier data and the illumination ON / OFF data compares the received illumination identifier data with preset identifier data to check whether they match each other (S111).

The n individual control modules store differently set identifier data for identification and use the previously stored identifier data to determine whether the illumination ON / OFF data transmitted together with the received illumination identifier data is valid data for itself.

If the received illumination identifier data matches predetermined identifier data, the SMPS 130 that supplies power to the illumination 10 using the received illumination ON / OFF data is controlled to turn the illumination 10 ON / OFF (S113).

If the received illumination identifier data does not match the preset identifier data, it determines that the received illumination ON / OFF data is not valid data to itself, and does not control the SMPS 130.

That is, the lighting control panel 110 and each of the lights 10 are controlled by applying the method of determining whether the data transmitted through the serial communication is valid or not by each of the individual control modules 120 and controlling the corresponding SMPS 130, So that the plurality of lights 10 can be centrally controlled with a simple configuration.

In addition, the lighting control system 100 of the present invention can control not only the ON / OFF of the illumination 10 but also the brightness through the serial communication data.

5 is a flowchart of a lighting control method according to another embodiment of the present invention.

Referring to FIG. 5, at least one illumination 10 desired to be controlled among the n lights 10 is input to the illumination control panel 110 (S201). When the user desires to control the illumination 10 through the one-touch input unit 111 or the number input unit 112 of the illumination control panel 110, the user selects whether to increase or decrease the brightness of the next selected illumination 10 ).

The input result is displayed on the display unit 114 of the illumination control panel 110 and then the illumination control panel 110 displays the illumination 10 selected through the one-touch input unit 111 or the number input unit 112 ), And generates illumination brightness up / down data corresponding to the illumination brightness up control input or the illumination brightness down control input (S205).

Next, the illumination control panel 110 transmits the generated illumination identifier data and the illumination brightness up / down data to the first individual control module 120 through the communication line 11 (S207).

When the first individual control module 120 receives the light identifier data and the illumination brightness up / down data, it transmits this data to the next individual control module 120 connected in series via the communication line 11, The illumination identifier data and the illumination brightness up / down data are sequentially transmitted to the connected nth individual control module 120 (S209).

Each of the n individual control modules 120 receiving the illumination identifier data and the illumination brightness up / down data compares the received illumination identifier data with preset identifier data and confirms whether they are matched (S211).

The n individual control modules determine whether the lightness brightness up / down data transmitted together with the received light identifier data is valid data for itself, using the stored identifier data, which is set differently for identification.

If the received illumination identifier data and predetermined identifier data match, the SMPS 130 that supplies power to the illumination 10 using the received illumination brightness up / down data is controlled to adjust the brightness of the illumination 10 (S213).

If the received illumination identifier data does not match the preset identifier data, it determines that the received illumination brightness up / down data is not valid data to itself and does not control the SMPS 130.

Through this process, the user can control a plurality of lights installed indoors or outdoors from one place. Even when the control system is not individually connected to each of the lights, the individual control modules for controlling the respective lights are connected in series Since it is connected with communication and data transmitted from the control system is shared at once, it is judged whether the data is valid and lighting is controlled. Therefore, ON / OFF control or brightness control can be performed by selecting only desired illumination even when only a simple communication line is constituted Do.

Those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope of the appended claims, The genius will be so self-evident.
