Incandescent lamps have a disadvantage in that they are inexpensive, have a short life time, have a low luminous efficiency, and can not be used in a large size.

Compared to the disadvantages of such illumination devices, light emitting diodes (LEDs) have high brightness and low power consumption, are easy to manage, have a high response speed, and have a long life, .

As a result, the use of LEDs as lighting devices has been widening in recent years. These LEDs are widely used in buildings where power consumption is high. For example, an LED can be used in a large space such as an office inside a building or a parking lot. That is, when the LED is used in a large space, a lighting control method is used in which the presence of a person or a vehicle is sensed through the sensor, and the driving of the LED is controlled using the sensing signal. In this case, there is a need for a method that can more accurately and easily control and manage LEDs.

The manager portable terminal 10 is a communication terminal that is carried by an administrator and capable of short range wireless communication and transmits lighting control information required for lighting control of a plurality of LED lighting apparatuses 40 by the LED lighting controller 20. [ For example, the administrator portable terminal 10 may be a mobile communication terminal, a smart phone, a tablet, a wearable terminal, a notebook, or the like, but is not limited thereto.

The illumination control information may include information on the illumination sequence, illuminance, on / off time, color, and the like of the plurality of LED illumination devices 40. The lighting control information includes information for setting the dimming time of the LED illuminating device 40 sequentially from the entrance and exit, and it is possible to provide the pedestrian with illumination from the entrance to the destination have.

The LED lighting controller 20 performs short-range wireless communication with at least some of the manager portable terminal 10 and the plurality of LED lighting apparatuses 40 and performs lighting control of the plurality of LED lighting apparatuses 40. [ That is, the LED lighting controller 20 transmits the lighting control information received from the manager portable terminal 10 to the LED lighting apparatus 40 in a range in which short-range wireless communication is possible through short-range wireless communication. At this time, the illumination control information transmitted from the LED lighting controller 20 to the plurality of LED illumination apparatuses 40 includes individual illumination control information for each LED illumination apparatus 40. [ That is, the illumination control information is allocated for each of the plurality of LED illumination devices 40, and the illumination control information includes the illumination control information for each of the LED illumination devices 40 at the assigned address.

Thus, the LED lighting controller 20 is a dedicated terminal for performing lighting control of the plurality of LED lighting apparatuses 40, and may be a kind of remote controller.

The plurality of LED lighting devices 40 include an LED module to perform illumination. The plurality of LED lighting apparatuses 40 perform short-range wireless communication with the LED lighting controller 20 or other LED lighting apparatuses 40 in a range where short-range wireless communication is possible. The plurality of LED lighting apparatuses 40 perform short-range wireless communication with other LED lighting apparatuses 40 in a cascade manner, extract only individual illumination control information assigned to them from the received illumination control information, And drives the LED module according to the control information to perform illumination.

Here, the cascade method is a method in which the LED lighting control device 40, which receives the lighting control information from the LED lighting controller 20, retransmits the lighting control information received by the other LED lighting control device 40.

Wireless communication between the LED lighting controller 20 and the LED lighting apparatus 40 and between the LED lighting apparatus 40 can be performed as follows.

In other words, the LED lighting system 100 according to the present embodiment is not a method of transmitting the same lighting control information to a plurality of LED lighting apparatuses 40 in the vicinity, Since the illumination control information includes the individual illumination control information for each of the plurality of LED illumination devices 40, the illumination settings for the plurality of LED illumination devices 40 can be individually Can be performed collectively.

In the case of a general short-range wireless communication method, there is a limit to the distance in which signals can be transmitted and received. However, since a signal, for example, illumination control information is transmitted between the LED lighting apparatuses 40 according to the present embodiment in a cascade manner, the coverage through which signals are transmitted through the short-range wireless communication system can be expanded. It is possible to solve the problem caused by the distance limitation.

Since the LED lighting control system 100 according to the present embodiment transmits a signal in a cascade manner between the LED lighting apparatuses 40, when the same signal is received, the corresponding signal is discarded, so that the infinite repeated operation Can be prevented.

The second short range wireless communication receiver 41 receives the first transmission information signal from the LED lighting controller 20 or the second transmission information signal from the other LED illuminator 40 through short range wireless communication. The second transmission information signal is a light control signal transmitted in a cascade manner from the LED lighting device 40 to the other LED lighting devices 40 in the same signal as the first transmission information signal.

The second address information extractor 43 determines whether the first or second transmission information signal received from the second short-range wireless communication receiver 41 is valid or not. As a result of the determination, the second address information extractor 43 extracts the address assigned to the second address information extractor 43 and transmits the extracted address to the second control information extractor 45. That is, the second address information extracting unit 43 identifies the addresses included in the received transmission information signal, and extracts the address assigned to itself.

The second control information extracting unit 45 extracts only the control value set to the address received from the second address information extracting unit 43 and transmits the extracted control value to the second transmission information control setting unit 47. [

The second transmission information control setting unit 47 transmits the individual illumination control information required for the operation setting of the LED module 59 according to the control value received from the second control information extracting unit 45 to the second illumination power source control unit 49, And transmits the first or the second transmission information signal to the second transmission information signal generating unit 51.

The second illumination power supply control unit 49 supplies power to the LED module 59 according to the individual illumination control information received from the second transmission information control setting unit 47 to perform illumination control.

[ The object detection sensor 55 may be an infrared sensor, an ultrasonic sensor, a camera, or the like, but is not limited thereto. Here, the object is an object of illumination, and can be a person or an automobile.

Then, the object detection signal processing unit 57 receives the detection signal indicating the proximity of the object from the object detection sensor 55 and transmits the detection signal to the second illumination power control unit 49.
