The transmission unit 110 is installed in the LED streetlight 100 for illuminating the road. The transmission unit 110 transmits the visible light signal 110a modulated with the position information including the height data. The visible light signal 110a communicates by using a visible wave. The visible light signal 110a is repeatedly turned on and off at a very high speed such that the LED light can not be seen by the eyes, and the light receiving unit senses the visible light signal. For example, it is possible to communicate by exchanging digital signals by setting the ON state to 1 and the OFF state to 0.

The storage unit 120 is installed in the LED street light 100 and stores the location information of the LED street light 100. The position information is included in the visible light signal 110a and is transmitted through the transmission unit 110. [

The central server 130 stores relevant information according to the position information of the LED streetlight or advertisement data according to the location information. The central server 130 is installed externally and is connected to the LED streetlight through a network.

The control unit 140 is connected to the central server 130 and receives and controls data transmitted from the central server 130. The control unit 140 searches for location related information or advertisement data stored in the central server 130 and transmits the retrieved data through the transmission unit 110 through visible light communication.

The network unit 150 allows the controller 140 and the central server 130 to access the network. For example, the network unit can use a wired / wireless Internet network, optical communication, power line communication, and the like.

Hereinafter, the operation of the information transmission system using the LED streetlight according to the first embodiment of the present invention will be described in detail with reference to the drawings.

That is, the LED street lamp always transmits the visible light signal including the position data through the transmitter (S110). When the user removes the user terminal 200 from the LED streetlight 100, the user terminal receives the visible light signal and receives the location data (S120). At this time, the user terminal 200 transmits the location data to the central server 130 using the mobile communication network 400 (S130). The central server 130 receiving the location data from the user terminal 200 searches the information related to the received location data and transmits the information to the user terminal at step S140. For example, location information of nearby restaurants, coffee shops, convenience stores, etc. can be provided according to the transmitted location information.

Meanwhile, FIG. 7 shows an example of a state in which POI information is utilized in the first and second embodiments of the present invention.

Referring to FIG. 7, the central server 130 transmits POI information or personal interest information of a user stored on the basis of the information of the user terminal 200 having received location information to the user terminal 200 S140a). For example, the user can receive previously stored information by pre-storing fields, frequent places, appointment places, and the like in which a user is interested in a specific location in advance through membership subscription or the like.

In addition, the central server 130 may analyze the area of interest based on the basic information of the user and the information previously input by the user, and may transmit advertisement data corresponding thereto. For example, if a user prefers a favorite coffee shop brand, the location information or advertisement data of the coffee shop brand entered by the user can be transmitted at a certain position, thereby enhancing the convenience of the user or enhancing the advertisement effect.

Meanwhile, FIG. 8 illustrates a situation in which, in the first and second embodiments of the present invention, the location information of the ED streetlight is used to predict the user's travel route and related information according to the travel route is transmitted to the user's mobile communication terminal . As shown in FIG. 8, the central server 130 predicts the movement path of the user using the position information of the LED street lamp sequentially transmitted while the user moves, To the communication terminal (S140b). For example, as shown in FIG. 8, when the user moves from the LED streetlight A 100a to the LED streetlight B 100b, the position information of the LED streetlight A 100a is changed to the position information of the LED streetlight B 100b . When the location information is changed due to the continuous movement of the location, the user can grasp the travel route, and the central server may be on the travel route or predict the travel route of the user and transmit the location related information according to the travel route . Also, the advertisement data according to the location information on the movement route can be transmitted to the user.

At this time, if the user activates the user terminal 200 under the LED streetlight, the user terminal can receive the visible light signal and receive the location data (S230). Meanwhile, the LED streetlight transmits a communication signal to communicate with the user terminal through the communication unit (S220). At this time, the user terminal may be connected to the LED streetlight by receiving the communication signal of the LED streetlight (S230). If the user terminal 200 and the communication unit 160 of the LED streetlight are connected to each other, the user terminal transmits the basic information of the user terminal to the communication unit at step S240. Then, the control unit of the LED streetlight transmits the position data of the LED streetlight and the basic information of the user terminal to the central server through the network unit at step S250. Then, the central server transmits peripheral related information according to the received location information to the controller through the network (S260), and the controller transmits the peripheral related information according to the location information to the user terminal through the communication unit (S270). For example, location information of nearby restaurants, coffee shops, convenience stores, etc. can be provided according to the transmitted location information.

7, the central server transmits POI information or personal interest information of the user stored on the basis of the location information and the basic information of the user terminal to the control unit of the LED street lamp through the network unit, And transmitting the POI information or the personal interest information of the user to the user terminal through the POI information. For example, the user can receive previously stored information by pre-storing fields, frequent places, appointment places, and the like in which a user is interested in a specific location in advance through membership subscription or the like.
