1 is a diagram conceptually explaining a network-controlled LED lighting system according to an embodiment.

As shown in FIG. 1, the LED lighting system of one embodiment basically provides lighting services from the management information processing device 100 through the network switch 200 when managing the operation of industry-related equipment, as in the existing case. This is achieved by controlling devices that perform air conditioning services, etc.

In this case, when this LED lighting system basically controls the lighting service, the management information processing device 100 controls the LED light blinking control operation of each LED light controller for each different facility to control the LED lights (LED light #1, Turn on/off LED light #2, ... ).

More specifically, it is as follows.

First, here, according to one embodiment, when controlling LED lights (LED light #1, LED light #2, ...), the LED lighting system switches the network for a number of different preset service types, Diversify networks to suit various services. At this time, LAN or Ethernet is used as the network.

In addition, when the LED lighting system diversifies such networks, it switches networks for each different control information, thereby efficiently using management resources and enabling smooth operation of LED lighting. In this case, the different control information is, for example, control signal information, control schedule information, etc.

Then, when the lighting service is extracted through this diversification, the LED lights (LED light #1, LED light #2, ...) installed for each different facility are integratedly controlled from the network method to provide various types of lighting services. Lighting service is provided.

Specifically, the network method uses the network switch 200 from the LED light information pre-grouped for different facilities and work units when controlling these LED lights (LED light #1, LED light #2, ...). By switching differently according to the manager's request, the LED lights blink collectively.

At this time, the LED lights are installed, for example, in Rooms 1 and 2 in a factory (community area) or a workplace (or a place with high humidity), and according to one embodiment, the user is installed according to the number of LED lights for each facility location. Power is supplied by grouping as desired.

At this time, the power supply is performed for each group desired by the manager by converting wireless power of LEDs by a magnetic field according to the number of LEDs in each facility location designated by the manager.

Additionally, the basic configuration applied to the LED lighting system of this embodiment is described below.

The LED lighting system largely includes a management information processing device 100, a network switch 200, and an LED controller (not shown).

Here, when managing the operation of a facility, the management information processing device 100 differently controls at least one service, including lighting service and air conditioning service, within each facility from preset schedule information or event information to control various facilities. Manage the environment as a whole.

In addition, when the network switch 200 receives a control signal from the management information processing device 100, the network switch 200 switches the input control signal based on pre-registered network information and transmits it to each service device for relaying. do.

In addition, when a control signal is transmitted by the network switch 200, the LED controller (not shown) controls the blinking operation, brightness, color, etc. of the LED lights it is in charge of, and turns on the LED lights according to the administrator's wishes. It runs.

Additionally, the LED lighting system of one embodiment wirelessly receives a control signal from the administrator mobile terminal when these LED lights (LED light #1, LED light #2, ...) are controlled, and the network switch (200) ) and a WiFi AP that allows transmission to the LED controller.

So, through this, in one embodiment, when controlling the LED lights of various facilities (LED light #1, LED light #2, ...), the operation of the LED controller such as blinking, brightness, color, etc. is controlled from this network configuration. By doing so, managers can conveniently provide lighting services at various times and locations.

Additionally, on the one hand, the LED controller according to one embodiment has the following configuration.

When using LED lights installed on the ceilings of various facilities within a factory (utility area), wireless power is generated by a magnetic field from the commercial power supply and supplied to the LED lights on the ceiling, so it is necessary to electrically connect the commercial power supply on the ceiling and the LED lights. It simplifies many wired wiring tasks and provides moisture-proof and waterproof stable power supply.

And, as another example, in this case, this LED controller generates wireless power by a magnetic field from PoE in addition to commercial power.

In addition, when using LED lights in this way, these LED controllers are installed in a attachable and detachable manner on the commercial power supply side (e.g. ballast) and the lighting fixtures such as LEDs on the ceiling, thereby improving the problems that appear when installed on the ceiling. Lighting fixtures are convenient to maintain and easy to install.

For this purpose, when the LED controller is installed, it attaches and detachably attaches itself to the ballast part of the commercial power supply and the LED lighting fixture using magnets, making installation on the lighting fixture easy and convenient (a detailed explanation of the attachment and detachment structure will be provided later). box).

Figure 2 is a diagram illustrating the entire network-controlled LED lighting system according to an embodiment.

As shown in FIG. 2, the system of one embodiment includes a plurality of LED controllers (300-1, 300-2, ...) that control the operation of LED lighting installed in a plurality of different workplaces, etc., and each LED controller ( It includes a network switch 200 that switches control signals to 300-1, 300-2, ...) and a management information processing device 100 that manages overall LED lighting control.

In this case, the system wirelessly receives power from the magnetic field from the commercial power source from each LED controller (300-1, 300-2, ...), so it is necessary to connect the commercial power source and LED lights in the ceiling to the existing electrical power source. It simplifies many wired wiring tasks and provides moisture-proof and waterproof stable power supply.

Additionally, as another example, the system receives PoE from each LED controller (300-1, 300-2, ...) through the network switch 200, so a magnetic field is induced by this PoE to control LEDs, etc. It also allows wireless power to be generated.

Basically, as before, the plurality of LED controllers (300-1, 300-2, ...) are in charge when the control signal of the management information processing device 100 is transmitted through the network switch 200. The LED lights are operated according to the administrator's wishes by controlling the blinking action, brightness, or color of the LED lights. In this state, according to one embodiment, when LEDs are operated for multiple different workplaces, the plurality of LED controllers (300-1, 300-2, ...) first provide various services of each facility from the network method. Among them, the lighting service is switched to plurality by the network switch 200 and extracted. Next, when the lighting service is switched in this way, the plurality of LED controllers (300-1, 300-2, ...) use a management information processing device ( 100) control signals are switched in an integrated manner, providing lighting services in various forms tailored to each facility. In addition, when a plurality of LED controllers (300-1, 300-2, ...) transmit the LED light number information including the LED control signal, the preset switching time of the driving power of one LED light and the Power is converted differently by converting it differently depending on the difference between the switching times of the driving power corresponding to each number of LEDs. In this case, when the power is converted in this way, the plurality of LED controllers (300-1, 300-2, ...) receive power from the existing commercial power source (or PoE, wireless, etc.) by magnetic induction method. It generates and provides wirelessly to LEDs on the ceiling, etc., thereby simplifying complex wiring work on the ceiling and enabling convenient power supply (a detailed explanation of this is given below).

Basically, when the network switch 200 receives a control signal from the management information processing device 100, it switches the input control signal based on pre-registered network information to control each LED controller (300- 1, 300-2, ...) and relay it. In this case, when the network switch 200 is switched in this way, it switches the network differently for a number of different preset service types, so it diversifies the network for various services and performs networking to suit the service provision desired by the user. Meanwhile, when the lighting service is switched accordingly, the network switch 200 transmits the LED control signal from the LED port table with control port information corresponding to a plurality of different LED lighting in advance to the different LED lighting service. Lighting services are provided on a job-by-job basis by switching each unit. At this time, the LED lighting service supplies power by grouping the number of LED lights for each facility location (or workplace) according to the user's wishes. In this case, the power supply converts the wireless power of LED lights by a magnetic field in one embodiment differently depending on the number of LED lights for each facility location designated by the manager, so that each group desired by the user, that is, LED lights It is done according to the environment (e.g., economical or product-specific work environment).

When managing the blinking operation of LED lights, the management information processing device 100 controls the flashing operation of LED lights in each facility differently based on preset schedule information or event information to manage the overall lighting environment of various facilities. . For example, when each LED light is used, the management information processing device 100 allows the user to send on or off control information of the LED light to a plurality of LED controllers (300-1, 300-2, ...). Since it is provided through a private network according to a preset LED light schedule, the LED light blinks according to the time desired by the user. And, in this state, according to one embodiment, when performing a lighting service, the management information processing device 100 includes the number of LED lights for each facility location (or workplace) to be driven for each LED lighting service in the LED control signal. Including information, etc., that is, providing lighting services tailored to each lighting environment, such as LED lighting.

Figure 3 is a block diagram showing the configuration of an LED controller applied to a network-controlled LED lighting system according to an embodiment.

As shown in FIG. 3, the LED controller 300 of one embodiment is attached to the stabilizer side of a commercial AC power source and includes a wireless power transmission transmitter 311 that generates power by a magnetic field from the commercial power supply and transmits it wirelessly to the surrounding area. Includes.

In addition, a receiving coil 312 that is spaced apart from the ballast and is attached to a lighting fixture such as an LED to receive this wireless power, a wireless power transmission receiver 314 that converts this wireless power into driving power such as an LED, and this driving power. It includes an LED driver 330 that drives the LED, and a control unit 320 that controls the driving operation of the LED.

Additionally, in the LED controller 300 of one embodiment, when status information such as an LED is detected, the control unit 320 provides the current status information to the management information processing device 100, so the management information processing device 100 It includes a communication module 340 that checks for abnormalities in the LED light.

In addition, in order to make the LED controller 300 easy to install on the ceiling, etc., when it is actually installed, it is fixed to the cable casing, a magnet is attached to the bottom, and the wireless power transmission transmitter 311 is located in the middle part. Includes a support part (not shown) installed on the.

In this case, the support is bonded to the lower surface of the support through a magnet, and the receiving coil 312 and the wireless power transmission receiver 314 are installed on the lower surface of the support, so that the entire device can be installed in a detachable manner. (not shown) is also included.

Additionally, on the other hand, this LED controller 300 includes a metal member (not shown) located below the receiving coil 312, and a ferrite blocking member (not shown) located below the metal member.

Therefore, when transmitting the received wireless power to the wireless power transmission receiver 314, the receiving coil 311 blocks electromagnetic waves from this wireless power and transmits the wireless power while preventing the magnetic field from being blocked to the outside. Since it is transmitted to the transmission receiver 314, the wireless power is transmitted as is.

In addition, when AC power is generated by the receiving coil 311, a shielding material is formed to surround the receiving coil 311, and a soft metal salient pole structure is formed in the inner direction of the receiving coil 311 to form an electromagnetic beam. Since it prevents eddy currents generated through surrounding metal, it also includes a guide member 313 that guides maximum wireless power.

On the other hand, in addition, the LED controller 300 configures the following configuration in the control unit 320 in order to selectively drive LED lights as many as the specific workplace and number of LED lights desired by the manager in a factory with many workshops. Because it is equipped, it achieves this.

Specifically, in this case, the control unit 320 first receives information on the number of LED lights for each workplace where LED lights will be used from the management information processing device 100, etc., and confirms the environmental type of the LED lights to be used.

Next, when the confirmation is completed, the control unit 320 controls the conversion operation of the LED driver 330 to provide driving power for the LED lights differently according to the number of LED lights for each workplace where the LED lights will be used, that is, wirelessly using a magnetic field. By converting direct current power from electric power, lighting services are provided according to the type of environment, such as LED desired by the user.

In this case, the information on the number of LED lights for each workplace is provided by the key signal input unit 340 or a separate detection unit (not shown), so that the user can identify the LED light environment information according to the LED light group desired. This is transmitted to the control unit 320.

When the communication module 340 receives a control signal set for each environment, such as the LED of the management information processing device 100, by switching for each different service type through a network switch, the communication module 340 extracts related information from the preset communication protocol and extracts the relevant information, such as the LED, etc. Obtain relevant information about control. In this case, the communication module 340 uses a communication protocol such as Ethernet, for example.

When an LED light is used, the wireless power transmission transmitter 311 is attached to the stabilizer of an existing commercial AC power source and derives power by a magnetic field from this commercial power source and wirelessly transmits it to surrounding LED lights, so it can be used in a specific location (e.g. It simplifies separate wired wiring work for LED lights installed on the ceiling and provides a power source. At this time, for example, when power is transmitted in this way, the wireless power transmission transmitter 311 strongly transmits the overvoltage protection unit connected to the stabilizer of commercial AC power (i.e., the SMPS unit of the ballast) and the DC power of this SMPS unit. It includes an HF inverter for this purpose and a coil for wireless power transmission that wirelessly transmits magnetic field power to the surrounding area using inverted power. For reference, the SMPS unit includes, for example, a line filter that removes noise from commercial AC power, a rectifier that converts to direct current power, a PFC unit that adjusts the phases of the voltage and current of the power supply to be the same, an overcurrent protection unit, and an overvoltage protection unit. Includes wealth.

When wireless power is transmitted from the ballast side by the wireless power transmission transmitter 311, the receiving coil 312 is detached from the LED side and receives this wireless power from its surroundings. In this case, the receiving coil 312 has a winding length equal to the separation distance from the wireless power transmission transmitter 311, so that the maximum wireless power is obtained.

When wireless power is received by the receiving coil 312, the wireless power transmission receiver 314 converts the received wireless power into DC power for driving power such as LEDs in a synchronous rectifier within the wireless power transmission receiver 314, so that the LEDs are driven. Make it possible. At this time, the wireless power transmission receiver 314 includes, for example, a communication FET, a synchronous rectifier, a clamp FET, and a WPTC. In this case, the WPTC monitors the power, voltage, current, etc. of the LED driver through mutual communication under the control of the control unit 320. Additionally, the communication FET turns on/off the load modulation signal of the WPTC, thereby communicating with the wireless power transmission transmitter 311. In addition, the clamp FET clamps against overvoltage when converted to direct current power through a synchronous rectifier, thereby preventing damage to the LED driver (i.e., LED driver 330).

The LED driver 330 converts the direct current power converted by the wireless power transmission receiver 314 into different values, thereby driving the LED lamp in various ways desired by the user.

When wireless power such as LEDs is generated by a magnetic field, the control unit 320 provides, for example, information on the number of LED lights for each workplace where the LED lights that the manager wants to use in the management information processing device 200 will be used. Check the type of environment for the LED lights to be used. Next, when the control unit 320 has completed the confirmation in this way, it controls the conversion operation of the LED driver 330 to convert the DC power of the driving power of the LED lamp differently depending on the workplace and number of LED lamps to be used, so that the LED lamp can be used for each type of environment. Lighting service is provided accordingly.

Additionally, in order to save power in consideration of the fact that the LED controller 300 uses LED lights and magnetic fields, the LED controller 300 determines the power consumption pattern of the LEDs in advance when turning the LED lights on/off in case an abnormality occurs. By providing an alarm, measures such as troubleshooting can be taken.

For this purpose, the control unit 320 has the following configuration.

a) That is, the control unit 320 learns and analyzes the power consumption pattern for LEDs based on the LED driving characteristics by the magnetic field using, for example, LSTM (Long short-term memory) and predicts for different power change patterns. Match and register power consumption.

In this case, the learning based on the charging characteristics of the charging unit confirms what tendencies and predictions are shown in conjunction with changes in the power consumption pattern.

b) Then, when driving the LED, the actual power change pattern is extracted.

c) Next, the actual power consumption according to the change pattern of the actual power extracted in this way is compared with the predicted power consumption matched to the change pattern of the actual power.

d) Therefore, as a result of the comparison, if the difference between actual power consumption and predicted power consumption falls within a preset range, an alarm is not provided to the pre-registered terminal, and if it falls within the preset range, an alarm is provided. .

Meanwhile, in addition, when the LED controller 300 generates a magnetic field from the wireless power transmission transmitter 311 to the receiving coil 312, the magnetic field is maintained at a strong state at a spaced apart location between the wireless power transmission coil and the receiving coil 312. A relay unit (not shown) is provided to maintain the .

Specifically, the first relay unit of one embodiment is composed of a wireless power transmission coil, a sub wireless power transmission coil and a sub receiving coil of shielding material spaced apart from each other forming a closed circuit, and is connected to both coils to cause resonance and impedance. It has a first variable capacitor that performs turn matching.

And, in this case, the receiving coil 312 is located within the closed path of the relay unit.

The second relay unit in another embodiment is composed of a conductive metal thin film of shielding material spaced apart from each other forming a closed circuit with the wireless power transmission coil and a sub-receiving coil, and is connected to the conductive metal thin film and the sub-receiving coil to perform resonance and impetance matching. and a second variable capacitor.

And, even in this case, the receiving coil 312 is located within the closed path of the relay unit.

Additionally, in order to maintain a strong magnetic flux at this time, the coil for wireless power transmission is, for example, wound around a magnetic core within the closed path of each relay unit, or is wound around a magnetic core to cancel out the magnetic flux generated in the closed path.

Therefore, through this, when the LED controller according to the embodiment generates a magnetic field from the wireless power transmission transmitter to the receiving coil, the magnetic field is maintained in a strong state between the coil on the transmitting side and the coil on the receiving side.
