The foregoing and additional aspects of the invention are described in detail below to enable those skilled in the art to readily understand and reproduce through the embodiments described with reference to the accompanying drawings.

1 is a block diagram showing the configuration of an intelligent lighting device according to the present invention.

The lighting device according to the present invention includes a light emitting unit 100 and a power supply unit 140.

It includes a mobile communication unit 116.

The short range communication unit 112 transmits and receives a control signal to a terminal device in a short range. In the present embodiment, the short range communication unit 112 may be implemented as one or more short range wireless communication modules such as an infrared communication module, a Bluetooth communication module, a Zigbee communication module, an ultrawideband (UWB) communication module, and an RF module.

The short range communication unit 112 may be implemented as a power line communication (PLC) module, that is, a power line communication module. PLC has the advantage that most devices connected to the home network need to be connected to a power outlet and that the devices driven by the power are connected to the power breaker, so that the network can be formed without any additional cable laying work.

In addition, the short-range communication unit 112 according to the present invention may be implemented as an RF (RF) communication module. The RF communication module communicates with a short range RF tag. As already known, the RF communication module may be configured as an antenna and an RF modulation and demodulation unit, and may be activated by power and transmit a radio signal. The RF tag, which is a separate component, is composed of a transponder chip made of semiconductor and an antenna. The RF tag and the RF communication module preferably exchange data wirelessly.

Accordingly, the lighting device may obtain identification information and data from the RF tag in the short range. For example, the intelligent lighting device according to the present invention can obtain information such as resident number and vehicle number information. In addition, the lighting apparatus may transmit the obtained information to the remote server through the communication unit 110. That is, it is possible to grasp the quantity and identification information of the moving vehicle around the intelligent lighting device based on the information read from the RFID reader of the lighting device, and to analyze the traffic volume information or search for the wanted vehicle. It can be effective.

In the present embodiment, the relay control unit 120 to be described later is associated with the authentication (Authentication) in order to manage its own wireless LAN service area according to the Institute of Electrical and Electronics Engineers (IEEE) 802.11 wireless LAN MAC The external devices 300a, 300b, and 300c that have completed the association process are controlled to access the network. Accordingly, the intelligent lighting device according to the present invention may be implemented as, for example, a park or a roadside street lamp, and may serve as an access point of terminals that have undergone authentication and combination in a predetermined area.

The wired communication unit 114 is connected to an internet communication network or an external network network through Ethernet. The wired communication unit 114 may be implemented as an Ethernet module or a wireless LAN (802.11 Wi-fi) module. In addition, the mobile communication unit 116 is connected to a mobile communication network such as binary CDMA, including an antenna and an RF circuit. The mobile communication unit 116 may receive a control signal from a mobile communication terminal through a mobile communication network.

In this case, only one master lighting device including the wired communication unit 114 or the mobile communication unit 116 may be provided in the home. Other lighting devices may include only the near field communication unit 112 as a slave lighting device and receive control signals received from the outside through the master lighting device. That is, in the master lighting device, the relay controller 120 transmits a control signal received from one of the short range communication unit 112, the wired communication unit 114, and the mobile communication unit 116 to another slave lighting device. For example, the relay controller 120 of the slave lighting device may determine whether to transmit a control signal in the form of a packet received from the outside to the terminal device through the short range communication unit 112 or to another lighting device.

The relay controller 120 includes a device searcher 124 and a control signal transmitter 126. The device search unit 124 searches for a terminal device corresponding to the received control signal.

The device search unit 124 searches for unique codes of the external terminal devices through the local area communication unit 112. In this case, the unique code of each device may be identification information of a short range wireless communication module mounted in each device. For example, the device search unit 124 finds and authenticates identification information indicating that the corresponding device is an air conditioner according to a unique code. The control signal transmitter 126 transmits the control signal received through the local area communication unit 112 to the air conditioner authenticated by the device search unit 124. Then, the air conditioner may receive a control signal through a pre-set and mounted short-range wireless communication module and operate according to a command of the control signal.

In one embodiment, if the corresponding device is not found in the device search unit 124, the relay control unit 120 of the intelligent lighting device transmits a control signal including the unique code information of the device to another external lighting device.

For example, in the case of the relay control unit 120 provided in the lighting device installed in the living room, in order to control the electric cooker or gas range is implemented to transmit to the intelligent lighting device installed in the kitchen. Accordingly, there is an effect that can realize a home network through a lighting device.

In addition, according to an additional aspect of the present invention, the relay control unit 120 may receive a control signal from the external terminal device through the communication unit. For example, a user may input a control signal for an indoor terminal device by using a remote controller while watching TV. Then, the lighting device may receive a control signal for the specific terminal device from the television or the remote control through the local area communication unit 112. The relay controller 120 transmits the control signal received through the local area communication unit 112 to another lighting device or a specific terminal device to be operated by the control signal through the local area communication unit 112 again.

In another embodiment, the relay control unit 120 may be implemented as a home server. The home server collectively controls the home network system. For example, the home server may be configured to include an embedded form in the lighting device. The relay control unit 120 connects to various home appliances such as gas valves, PDP televisions, washing machines, air conditioners, microwave ovens, remote meter reading devices, remote diagnostic terminals, etc., through different protocol LANs through the communication unit 110. do. At this time, the relay control unit 120 transmits a control signal to the corresponding devices through the communication unit 110 according to the control signal received through the communication unit 110. In addition, the intelligent lighting device further includes a storage unit, and is preferably implemented to store information necessary to perform a home network, such as information on each home appliance.

According to another aspect of the present invention, an intelligent lighting device includes a state information DB 135 that stores reference data about an operation state, a state detection unit 132 that detects the operation state, and a detection result in comparison with reference data. And a self-diagnostic unit 134 for outputting a diagnosis result through the communication unit 110.

The state information DB 135 stores the initial operation value of the lighting device. For example, the luminaire stores reference data such as measured voltage, current, temperature, and illuminance for each configuration at the time of initial operation.

The state detecting unit 132 may be a temperature sensor or an electric leakage sensor that is separately provided. That is, the state detection unit 132 measures the current, voltage, temperature, illuminance, etc. for each configuration of the lighting device and outputs the measurement result. Additionally, the state detecting unit 132 may further include an approach sensor for detecting an approach of an object or a human body.

The self diagnosis unit 134 compares the detection result of the state detection unit 132 with reference data stored in the state information DB 135 to diagnose and evaluate an operation state of the lighting device. Accordingly, by comparing the power consumption and the current magnitude with the reference data, it is possible to determine the state of the lighting device, such as the remaining life of the lighting device in advance.

In addition, in one embodiment, the self-diagnostic unit 134 calculates an average value of the detection result of the state detecting unit 132 in units of a certain period of time, such as one week or ten days. The calculation result is stored in the state information DB 135, and the result value detected in real time by the state detection unit 132 is compared with the stored calculation result value. Accordingly, it is possible to detect whether a sudden abnormality occurs.

According to an additional aspect, the apparatus further includes a power cut-off unit 160, and as a result of a self-diagnosis in the self-diagnostic unit 134, when a short circuit occurs, the power transmission unit 140 cuts a power transmission path to which power is transmitted to the outside. In one embodiment, the power interrupter 160 may be implemented as an earth leakage breaker. However, it is not limited thereto. In one embodiment, a plurality of intelligent lighting devices are connected in parallel to receive power from the power project. That is, the power supply unit 140 receives power from the outside through the path a. Then, the authorized power is transmitted to other external lighting devices through the b path again. In this case, when a self-diagnosis result leakage occurs in the self-diagnosis unit 134, the power transmission path to which power is supplied to another lighting device is blocked, thereby preventing power supply to other lighting devices connected to the power transmission path. In other words, it is possible to prevent accidents caused by leakage.

In addition, the controller 130 may be implemented to cut off the input power when the leakage current and the operating temperature are higher than the set value. This enables the remote terminal to quickly identify and repair the state of the street lamp and the light emitting state of the LED, whether a short circuit occurs, or a failure state of each component, and prevent an accident due to a short circuit or overheating.

A DSP is a digital signal processing processor that compresses or reconstructs voice signals in accordance with Internet telephony standards. In this embodiment, the voice call controller 125 compresses voice data input through the microphone 155 in accordance with Internet telephone standards and transmits the voice data through the wired communication unit 114. Then, the signal compressed according to the Internet telephony standard received by the network communication unit is decompressed, converted into voice data, amplified, and output as audible sound through the speaker 155. In the present embodiment, the voice call controller 122 may perform an Internet telephone function for performing voice data transmission and reception according to Voice over Internet Protocol (VoIP) through the Internet.

In addition, the voice call controller 122 may be implemented to enable voice recognition. In other words, it recognizes the voice input through the microphone 155 to grasp the receiver information such as a telephone number, and to request the call connection to the identified receiver. In another embodiment, the communication unit 110 may be implemented to obtain a receiver information from an external device capable of inputting an operation signal, such as a remote controller or a telephone, to request a call connection to a corresponding telephone number.

According to another aspect of the present invention, the intelligent lighting device includes a battery 145 for storing emergency power and a charging unit for charging the battery 145 with emergency power at least a part of the power supplied from the power supply unit 140 ( 136).
