First, the Zigbee communication module described in the present invention will be described.

ZigBee refers to low power wireless short range standard 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.

A typical battery can be used for more than a year and the transmission speed is up to 250 Kbps in the 2.4GHz band.

Up to 65,536 nodes can be attached to the network, and even star, cluster tree and mesh network networks are supported.

The present invention uses the characteristics of the ZigBee (ZigBee), by attaching a ZigBee communication module to the LED lighting system, so that the lights are turned on by using a wireless control switching device.

The present invention is a Zigbee communication system consisting of a control controller 100, a coordinator module 200, a group supervisor 300, a node module 400,

The control controller 100 additionally installs a program code for applying an LED lamp control signal, and additionally connects a constant current control unit 500 for controlling LED lamps to the node module 400 and to human body sensing or external light. And a node sensor module 600 that senses and transfers information to the group supervisor 300.

The control controller 100 outputs a control signal for overall control of each LED lighting, and is configured to receive power supplied from KEPCO and attached to an arbitrary place, and uses a touch panel at the front side. It is additionally installed so that a user can input a control signal through the touch panel or a light control signal through a wireless control device such as a remote controller.

The coordinator module 200 outputs a control signal of the control controller 100 as a ZigBee wireless signal, and converts the control signal related to the LED module of the control controller 100 into a signal of a frequency range allowed by the Zigbee communication module. do.

The group supervisor 300 relays an output signal of the coordinator module 200 and collects and outputs information output from the node sensor module 600.

The node sensor module 600 outputs the LED lamp to be turned on or off by dimming control by sensing a human body sensing or light sensing, and turns on or off an LED according to the body sensing information or the light sensing information, or raises it to an appropriate brightness. To induce dimming control.

The node module 400 receives the control signal of the control controller 100 and the sensor information of the node sensor module 600 input from the group supervisor 300.

At this time, the control controller 100 is assigned to the unique address is stored in the internal storage, and correspondingly, the unique address is also assigned to the group supervisor 300 and the node module 400. Accordingly, the unique address of the control controller 100 is linked to the group supervisor 300, and the supervisor 300 controls the plurality of LED modules 700 by interlocking the unique address with the node module 400. You can control all at once.

When an illumination lighting signal is input from the illumination signal input / output panel to the control controller 100, a digital signal is generated by combining a control signal with a magnetic eigenvalue stored in the control controller 100 and transmitted through the coordinator module.

Then, the group supervisor 300 receives the control signal of the control controller 100 and transmits it to the node module 400.

Meanwhile, the group supervisor 300 is connected to a node sensor module 600 such as a human body sensor or a light detection sensor, and the sensor information received from the node sensor module 600 is constant current through the node module 400. By transmitting to the controller 500, the LED module is properly dimmed or controlled according to the external light change, so that light of a constant intensity is automatically output.

That is, even when the lamp off signal is output from the control controller 100, when the manual switch 900 outputs the on signal, the constant current controller 500 outputs the current of the SMPS 800 to turn on the lamp 700. . When the manual switch 900 is turned off, a signal from the control controller 100 is immediately received to control the lamp according to the pre-programmed contents.

Accordingly, when the manual switch 900 is turned on, the control signal of the control controller 100 is ignored and the lamp is immediately turned on. When the manual switch 900 is turned off, the dimming of the lamp 700 is performed according to the control signal of the control controller 100.
