Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

LED lighting control system 100 using a low-power wireless communication module according to the first embodiment of the present invention is the LED lighting unit A ~ G (110a ~ 110g), lighting control unit A ~ G (120a ~ 120g) and sensor unit 130 It includes.

LED lighting unit (110a ~ 110g) is at least one number, the LED lighting unit (110a ~ 110g) may be located in the interior or underground runner window of a large building, such as offices, department stores. In the LED lighting control system 100 using the low power wireless communication module according to the first embodiment of the present invention, as shown in FIG. 1, seven LED lighting units 110a to 110g are illustrated, but are not necessarily limited thereto. The number required depends on the internal structure of the building. In addition, the LED lighting unit (110a ~ 110g) means a basic unit that is individually controlled, lighting, off, brightness, etc., and includes at least one or more LED lighting elements, and generates lighting. Here, the LED lighting unit (110a ~ 110g) has a unique identifier for distinguishing each, IP address can be used as such identifier.

The lighting controllers 120a to 120g have a number corresponding to the LED lighting units 110a to 110g and control the operation of the corresponding LED lighting units 110a to 110g according to the received control signal. More specifically, the lighting controllers 120a to 120g include a low power wireless communication module and control the on / off operation of the corresponding LED lighting units 110a to 110g according to a control signal received through the low power wireless communication module. In the LED lighting control system 100 using the low power wireless communication module according to the first embodiment of the present invention, although the LED lighting units 110a to 110g and the lighting control units 120a to 120g are represented as separate devices, the lighting control unit 120a ~ 120g) may be implemented as one device included in the LED lighting unit (110a ~ 110g). Therefore, in the following description, the LED lighting units 110a to 110g and the lighting controllers 120a to 120g are not distinguished, and even if described, there will be no problem in recognizing the contents.

The sensor unit 130 is positioned around the LED lighting units 110a to 110g and senses the surrounding environment of the LED lighting units 110a to 110g. In the lighting control system 100 using the low power wireless communication module according to the first embodiment of the present invention, only one sensor unit 130 is present, but is not necessarily limited thereto. That is, two or more sensor units 130 may exist according to the lighting control environment and the positions of the LED lighting units 110a to 110g. Since the sensor unit 130 is generally used to detect the presence of a person, a human body sensor may be utilized. The sensor unit 130 detects the presence / absence of a human body in a predetermined space around the LED lighting units 110a to 110g in real time, and outputs a control signal according to the detected result. Here, the human body sensor may be used superconducting sensors using infrared sensing, temperature sensing, ultrasonic sensing. In addition, in addition to the human body detection sensor, an illumination intensity sensor or a motion detection sensor may be used as the sensor unit 130 to detect brightness or movement of light. For example, when the LED lighting control system 100 using the low power wireless communication module according to the first embodiment of the present invention is installed in a parking lot, an illumination intensity sensor is configured to detect a light of a headlight of a vehicle. 130). In addition, at least two sensor units may be located inside the lighting control unit. In this case, the lighting controller may receive the value detected by the sensor unit and output a control signal like the sensor unit.

As such, when a person or light is sensed through the sensor unit 130, the sensor unit 130 controls to instruct on of a specific LED lighting unit among the plurality of LED lighting units 110a to 110g using a low power wireless communication module. Output the signal. More specifically, among the plurality of LED lighting units constituting the LED light control system 100, some LED lighting units are set as one group, and the sensor unit 130 controls to instruct on of the LED lighting unit corresponding to the set group. Can output a signal. In this case, the set group may be represented by the same ID. For example, the LED lighting control system 100 sets some of the LED lighting units 110a to 110c as a group among all the LED lighting units 110a to 110g, and sets a person or light in the sensor unit 130. If detected, a control signal for turning on the LED lighting units 110a to 110c corresponding to the set group may be output. At this time, the output control signal includes the set group ID.

In addition, the sensor unit 130 may output a control signal instructing to turn on a specific LED lighting unit among the plurality of LED lighting units 110a to 110g. For example, when the sensor unit 130 detects a person or light, it may output a control signal for turning on only the specific LED lighting unit 110a. At this time, the output control signal includes the IP address of the specific LED lighting unit.

As such, the sensor unit 130 may output a control signal for turning on a group or one LED lighting unit according to the setting of the LED lighting control system 100.

Hereinafter, referring to FIG. 2, the operation of the sensor unit 130 and the lighting control unit 120a of the LED lighting control system 100 shown in FIG. 1 will be described.

The sensor unit 130 includes a sensing module 131 and a first communication module 132. The sensing module 131 detects the surrounding environment of the sensor unit 130 and transmits the detection result to the first communication module 132. The first communication module 131 may use a low power wireless communication module. More specifically, the Zigbee communication module can be used. Zigbee refers to a low power wireless near field communication technology. It is best suited for low cost, very low power consumption, small size and program, fast speed at short distance, and rare network usage. The transmission rate is up to 250Kbps in the 2.4GHz band. In addition, the communication distance is about 100 ~ 500m, power consumption is less than 500kW.

Therefore, the sensor unit 130 senses the surrounding environment through the sensing module 131 and broadcasts a control signal based on the detected result through the first communication module 131. In this case, the control signal may include a control command for instructing the LED lighting units included in the set group or one LED lighting unit. In this case, the sensor unit 130 broadcasts a control signal through the lighting control unit 120a and the low power wireless communication module. That is, the control signal may include the ID of the group or the address of the LED lighting unit. Further, according to the ID of the group included in the control signal or the address of the LED lighting unit, the lighting control unit receiving the control signal turns on the designated LED lighting unit.

The lighting controller 120a includes a second communication module 121, a controller 122, and a switch 123. Like the first communication module 131 of the sensor unit 130, the second communication module 121 may use a Zigbee communication module which is a low power wireless communication module. The second communication module 121 receives a control signal and transmits the received control signal to the controller 122. The controller 122 turns on the corresponding LED lighting unit according to the control signal received from the second communication module 121. More specifically, the controller 122 turns on the corresponding LED lighting unit when the control signal transmitted from the second communication module 121 includes a control command instructing to turn on the corresponding LED lighting unit. For example, the controller 122 turns on the LED lighting unit 110a when receiving a control signal including a control command instructing the on of the LED lighting unit 110a from the second communication module 121. On the other hand, when receiving a control signal including a control command instructing the on of the other LED lighting unit 110c from the second communication module 121, the LED lighting unit 110a is not turned on.

The switch 123 first sets whether or not to transmit a control command included in the received control signal to another lighting controller, and sets the control command to be transmitted to the other lighting controller. Set the position of the LED lighting to transmit. That is, the switch 123 first sets whether or not to operate the other LED lighting unit in response to the received control signal, and if it is set to operate the other LED lighting unit, sets the position of the other LED lighting unit. In this case, the location of the LED lighting unit may be an ID of a group to which the LED lighting units belong or an IP address of one LED lighting unit. The second communication module 121 broadcasts a control signal based on the value set in the switch 123.

For example, the switch 123 of the lighting controller 120a may be set to not operate the other LED lighting controller. In this case, the second communication module 121 does not broadcast the control signal. On the other hand, the switch 123 of the lighting control unit 120a sets another LED lighting control unit to operate, sets an ID of a group including the lighting control unit 120a to a position of another LED lighting control unit to be operated, An ID of another group that does not include the lighting controller 120a may be set, or an IP address of the specific lighting controller 120c may be set. The second communication module 121 broadcasts a control signal based on the value set by the switch 123, and the lighting controller receiving the broadcast signal corresponds to the LED lighting unit according to the control command included in the received control signal. Control the operation. As the switch 123, a hardware switch capable of setting the value in hardware may be used, and a dip switch capable of freely setting and changing the value in hardware is mainly used. The hardware switch value may also be controlled via a remote control which is a remote control means based on a low power wireless network. That is, not only the value of the switch 123 of the lighting controller 120a may be directly set and changed, but also the value of the switch 123 may be set and changed through the remote controller. Accordingly, the value set by the switch 123 can be easily set and changed by the user. Even if the lighting control unit 120a is replaced, the value set by the switch 123 can be kept constant, so that the entire control system can be kept the same. have.

In general, when a control signal is transmitted and received using a low power wireless communication module, a control failure may occur due to a transmission distance of the signal and a collision between the control signal. However, in the LED lighting control system according to the first embodiment of the present invention, the address of another LED lighting unit is set by using a switch of the lighting control unit, and the control signal is broadcast again to the set address. Thus, the effect of expanding the control region can be obtained.

As illustrated in FIG. 3, the sensor unit 130 broadcasts a control signal for operating the first lighting control unit 120a and the second lighting control unit 120b. The first lighting controller 120a receiving the control signal broadcast from the sensor unit 130 sets the first group 300 to an address to which a control command included in the received control signal is transmitted using a switch. The control signal for instructing the operation of the LED lighting unit included in the group 1 300 is broadcast. As shown in FIG. 3, the first group includes a third lighting controller 120c, a fourth lighting controller 120d, and a fifth lighting controller 120e.

In addition, the second lighting control unit 120b receiving the control signal broadcast from the sensor unit 130 sets the sixth lighting control unit 120f as an address to transmit a control command included in the received control signal using a switch. In this case, a control signal indicating the operation of the sixth lighting controller 120f may be broadcast by the second lighting controller 120b.

Therefore, the area that can be controlled by the sensor unit 130 is not only the first lighting control unit 120a and the second lighting control unit 120b but also the third lighting control unit 120c, the fourth lighting control unit 120d, and the fifth. The lighting controller 120e and the sixth lighting controller 120f may be enlarged. As such, the LED lighting control system 100 using the low power wireless communication module according to the first embodiment of the present invention has a network structure of a tree shape. Therefore, even when replacing the LED lighting unit constituting the LED lighting control system 100, or add a new LED lighting unit it is possible to conveniently build a control system for controlling the LED lighting unit. In addition, in one embodiment of the present invention, only one sensor unit is shown, but two or more sensor units may be used to control a plurality of LED lighting units, and different sensor units broadcast control signals for operating the same LED lighting unit, respectively. You may.

The sensor unit 430, the lighting control unit 420a and the remote control unit 440 may be used. ) Performs communication via this low power wireless communication module. The control signal generator 442 of the remote controller 440 may control the second control unit to selectively operate at least one or more other LED lighting units according to a preset value in response to the first control signal received from the sensor unit 430. Generate a signal. That is, in the lighting control system 100 of FIG. 1, the above-described second control signal is generated by the switch 123 included in the lighting control unit 120a. However, the lighting control system 420a of the lighting control system 400 of FIG.
