Referring to FIG. 1, the illumination control apparatus includes a plurality of illumination modules 100, 110 and 120, a plurality of SMPSs 200, 210 and 220, and a main controller 400.

In FIGS. 1 and 2, the first, second, and third illuminating lamp modules 100, 110, and 120 may be described as first to N illuminating lamp modules. In FIGS. 1 and 2, ). Here, K may be (1 < = K < N).

One illumination lamp module 100 is composed of an illumination lamp 101 and an illumination lamp controller 102 for controlling the illumination lamp 101. [

The plurality of illumination lamp modules 100, 110, and 120 are interconnected. By way of example, multiple lighting modules may be interconnected via power line communication.

The plurality of SMPSs 200, 210 and 220 supply power to the plurality of illumination modules 100, 110 and 120 and support a power line communication path for mutual communication connection of the plurality of illumination modules 100, 110 and 120. For example, the first SMPS 200 supplies power to the first lamp module 100.

The main controller 400 controls the plurality of illumination lamp modules 100, 110, and 120. In particular, the main controller 400 sequentially controls the plurality of light module 100, 110, and 120 through point-to-point communication (P2P communication). Here, the control for the plurality of illumination lamp modules 100, 110, and 120 includes operation control for turning on or off the illumination lamp, state control including the illuminance of the illumination lamp, temperature and power factor, and the like.

In the present invention, the above-mentioned point-to-point communication can be achieved through power line communication by a plurality of SMPSs 200, 210 and 220. As another example, the above-mentioned point-to-point communication can be performed through a wireless communication network.

In the present invention, the multiple SMPSs 200, 210, and 220 and the main controller 400 have unique identification numbers for asynchronously and independently controlling the operation and control of the illumination lamp, respectively, and the plurality of illumination lamp modules 100, 110, Lt; / RTI > In particular, when a plurality of illumination lamp modules are connected to one SMPS (200 or 210 or 220), an identification number to which the arrangement order is added is assigned to a unique identification number assigned to the one SMPS (200, 210 or 220) . For example, when the identification number of S1 is assigned to the first SMPS 200, the identification number of the first illumination module among the plurality of illumination modules connected to the first SMPS 200 is assigned to S11, The identification number can be assigned to S12. However, as shown in FIGS. 1 and 2, since the plurality of illumination modules 100, 110, and 120 and the plurality of SMPS 200, 210, and 220 correspond to each other in a one-to-one correspondence, the illumination module can be identified by identification numbers assigned to the plurality of SMPS 200, 210, and 220.

The operation according to the configuration of the above-described illumination control apparatus will be described with reference to Figs. 1 and 2. Fig.

The main controller 400 sequentially transmits control signals CONTROL for controlling operation or state control to the plurality of illumination lamp modules 100, 110 and 120 by point-to-point communication. In response to the control signal of the main controller 400, the plurality of lamp modules 100, 110 and 120 respectively transmit to the main controller 400 a response signal (ACK) including the status information of the illuminated lamp that it controls.

The main controller 400 receives response signals including status information of the illumination lamps from the plurality of illumination lamp modules 100, 110 and 120, respectively, and stores them in the database.

The main controller 400 collects state information for each illumination lamp in response signals received from the plurality of illumination lamp modules 100, 110, and 120, and supplies the collected state information to each identification number uniquely assigned to the plurality of illumination lamp modules 100, 110, And can be stored in a database in association with each other.

Meanwhile, the main controller 400 determines that the K light illumination module 120 is in an abnormal state as a response signal is not received from the K light illumination module 120 among the plurality of the light illumination modules 100, 110, and 120. The main controller 400 stops transmitting the control signal to the K-th light module 120 and at the same time, notifies the (K-1) light module 110 having a placement order earlier than the K-th light module 120 And commands the K light illumination module 120 to transmit the periodic control signal (COMMAND1). The control signal CONT transmitted from the (K-1) lamp module 110 to the K lamp module 120 is a control signal transmitted from the (K-1) lamp module 110 to the main controller 400 And the (K-1) lamp module 110 may be any one of the lamp modules that have already successfully transmitted the response signal to the main jitterer 400. For example, the (K-1) light module 110 transmits a periodic control signal to the K light module 120 through the power line communication path. As another example, the (K-1) light module 110 may transmit the periodic control signal to the K light module 120 through the wireless communication network.

Then, the main controller 400 transmits a periodic control signal to the (K-1) light module 110 to the K light module 120 as a response signal is received from the K light module 120 Command to stop (COMMAND2).

The main controller 400 instructs the (K-1) lighting lamp module 110 to transmit the periodic control signals to the K lighting lamp module 120, And transmits the control signal to the (K + 1) lamp module (not shown).

An identification number of the SMPS for identification of the plurality of illumination modules 100, 110 and 120 is inserted into a response signal transmitted from the plurality of illumination modules 100, 110 and 120. The response signal includes power factor information of each illumination light provided to the plurality of illumination modules 100, Information.

As described above, the main controller 400 controls the plurality of illumination lamp modules 100, 110 and 120 by sequentially transmitting control signals for controlling operation or control signals for controlling the state to the plurality of illumination lamp modules 100, 110 and 120.

The plurality of illumination lamp modules 100, 110, and 120 may turn on or off the illumination lamp or adjust the illuminance according to a control signal received from the main controller 400. On the other hand, the state information including the temperature and the power factor can be used as the reference information for the operation control of the illumination lamp by the main controller 400.

FIG. 2 is a flowchart illustrating a lighting control method according to an exemplary embodiment of the present invention, and is a flowchart illustrating a method of controlling a plurality of lighting modules connected to each other while having a lighting lamp and a lighting controller for controlling the lighting lamp. Particularly, the above-mentioned main controller shows a procedure for controlling a plurality of illumination lamp modules.

The main controller sequentially transmits control signals for controlling illumination of the illumination lamps, which are respectively provided in the plurality of illumination lamp modules, to the plurality of illumination lamp modules using point-to-point communication.

Then, when the plurality of illumination lamp modules are in a normal state, the main controller sequentially receives response signals (ACK) including status information of each illumination lamp from the plurality of illumination lamp modules.

The control operation of the main controller will be described with reference to Fig.

The main controller transmits a control signal to the K-th light fixture module (S100). Here, K may be (1 ≤ K ≤ N) indicating the number of illumination lamp modules. Then, the main controller transmits a control signal to the (K + 1) lamp module (S120). The time interval at which the main controller transmits the control signal and receives the response signal can be variously modified according to the configuration of the illumination control apparatus or according to the quality of the communication line according to the present invention.

For example, the main controller may transmit a control signal to the (K + 1) luminaire module after transmitting a control signal to the k < th > luminaire module and receiving a response signal (ACK) .

As another example, the main controller may transmit control signals from the first illumination module to the Nth illumination module sequentially, and receive the response signal (ACK) from the first through N lightening modules at any time.

(K-1) lamp module having a placement order earlier than that of the K-K lamp module is periodically controlled by the K-K lamp module, when the response signal is not received from the K-Koom lamp module (S110) (S130). Here, the K-th light module can be identified by the identification number of the K-th SMPS, and the (K-1) light module can be identified by the identification number of the (K-1) SMPS. Accordingly, when the main controller instructs the (K-1) light module to transmit the periodic control signal to the K light module, the identification number assigned to the corresponding SMPS can be used.

Thereafter, when a response signal is received from the K-th light fixture module (S140), the main controller instructs the (K-1) light fixture module to suspend transmission of the periodic control signal to the K-th light fixture module (S150) . Accordingly, the (K-1) lamp module stops transmitting the control signal to the K module lamp module. Here, the control signal transmission path between the (K-1) light module and the K-th light module may be a power line communication path supported by the SMPS.

As another example of the present invention, in the above description, the main controller 400 transmits a control signal to the K light illumination module 120, to which the response signal is not received, to the K light illumination module 120, -1) to the illumination lamp module 110. However, regardless of the arrangement order, the main controller 400 transmits a control signal to any one of the illumination lamp modules that successfully received the response signal (ACK) To command the transmission of the control signal to the illumination lamp module 120. [
