Navigational signs are lighthouses, lights, docks, buoys, fog signals that serve as indicators for ships navigating ports, bays, straits, other inland waters, territorial seas, and exclusive economic zones by means of lights, shapes, colors, sounds, radio waves, etc. Refers to radio wave signs, special signal signs, etc. Types of navigational aids include manned lighthouses, unmanned lighthouses, light beacons, guidance lights, survey lights, direction lights, light poles, bridge lights, traffic lights, light waves including light buoys, spar buoys, LANBYs, and light ships. cover can be found. Among these, a lantern refers to a lighting device that refracts and reflects light from a light source using a lens among lighting devices used for light wave signs and radiates it to the outside to assist a sailing ship in determining its position.

In general, maritime route indication lights are mounted on light buoys installed on the sea and generate high luminous intensity, so that ships in operation can check the light of the lights even at about 8 nautical miles from the sea on cloudy days or foggy days or at night. It is used as a guidance light that enables safe operation or returns to the port by enabling this. In addition, most of these lanterns use LEDs having excellent straightness characteristics in order to have a long lifespan with low power consumption and to radiate light with high luminous intensity to a far distance.

Conventionally, a multi-functional solar cell-integrated lantern technology for marine use has been known. In this technology, the main light source LED is installed inside the upper light body, and the auxiliary light source LED and the ring-shaped condensing lens are installed on top of the main light source LED. The sensing unit detects this and immediately supplies power to the preliminary light source LED so that the preliminary light source LED is emitted.

However, the conventional all-in-one lantern for marine use may face a situation in which it does not properly function as a navigational aid due to a lack of power supply depending on the climatic conditions of the sea. Above all, the prior art is provided in the form of a solar cell attached to the upper light body. In the case of an LED lantern with this structure, unlike land solar power generation facilities, the lantern facing harsher environments such as bad weather, seawater and sea wind. Considering the conditions of use, the solar light collection efficiency of the solar cell is rapidly degraded, and replacement and repair may be required accordingly.

In addition, in the case of the prior art, if you want to replace the solar cell, you have to replace the entire upper light body, so there is a problem that is economically very inefficient in terms of cost and waste of raw materials.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a diagram showing an integrated marine lantern power system according to an embodiment of the present invention, and FIG. 2 is a schematic diagram showing the marine integrated lantern power system of FIG. 1 .

As shown in FIGS. 1 and 2 , an integrated marine lantern power system 90 according to an embodiment of the present invention includes a power supply device 100 and an integrated marine lantern 110 .

As shown in FIG. 2A , the power supply device 100 may be fixed and installed to a frame constituting the integrated marine lantern 110 . Alternatively, the power supply device 100 may be configured to be connected to a land power source or a marine storage battery in order to perform a wireless power transmission operation with the integrated marine lantern 110.

The power supply device 100 according to an embodiment of the present invention may perform power transmission using a magnetic resonance method or a magnetic flow method in order to transmit power to the integrated marine lantern 110 . Here, in the magnetic resonance method, each coil is configured in the power supply unit and the power receiver unit, and a resonance coil may be additionally configured in proximity to the coil in the power receiver unit. The magnetic resonance method can use a frequency of 1 to 15 MHz, and the charging distance reaches several meters. In addition, the charging efficiency reaches 40 ~ 60%. On the other hand, the magnetic induction method uses a ferrite core, and unlike the magnetic resonance method, a known coil is not additionally configured. A frequency of 0.1 ~ 100 MHz is used, and a charging distance of several cm is appropriate. The charging efficiency is more than 75%.

Therefore, in the embodiment of the present invention, in order to perform wireless power transmission to the integrated marine lantern 110 at a distance of several m depending on the installation location, etc. Resonance method can be installed and used. In addition, in the case of installing the power supply device 100 in an adjacent place as shown in FIG. 2A, it may be installed and used in a magnetic induction method. Of course, this is to increase the charging efficiency.

Of course, the power feeding device 100 according to the embodiment of the present invention may be configured in a hybrid form so that the power feeding device 100 is selectively operated according to a manager's request. For example, since the power supply device 100 is configured in the form of a toggle switch, it is possible to perform magnetic resonance power supply at position A and magnetic induction power supply at position B. This can be understood as "selectively operating", and when installation and replacement of the device is cumbersome, selection can be made fully automatically through remote control. In addition, when a circuit diagram of a specific method malfunctions, power is supplied in another method. Of course, when the power supply method of the power feeding device 100 is changed, the integrated marine lantern 110 may also change the power receiving method and operate in matching with the power feeding device 100.

More specifically, the magnetic induction method is a method of transmitting power using a magnetic field induced in a coil. It is a technology in which most of the magnetic field generated from the current flowing in the primary coil, such as a transformer (or ferrite core), passes through the secondary coil, and induced current flows through the secondary coil to supply energy to the load. The basic principle of magnetic induction is explained by Ampere's law and Faraday's law of electromagnetic induction. A characteristic of the magnetic induction method is that the natural resonant frequency of each coil may be different from the transmission frequency that actually transmits energy. This enables the miniaturization of the coil, but simultaneously has a disadvantage that the transmission distance also decreases as the size of the coil decreases.

On the other hand, the magnetic resonance method is similar to the magnetic induction method in that the magnetic field generated from the current flowing in the primary coil passes through the secondary coil and the induced current is generated, but both the resonance frequency of the primary coil and the secondary coil are Manufactured in the same way, energy generated in the primary coil is transferred to the secondary coil through resonance mode energy coupling between the coils. Unlike long-distance electromagnetic radiation, the magnetic resonance method uses the near-field effect as it is transmitted at a shorter distance than the frequency/wavelength used, and goes beyond the existing magnetic induction and matches the resonance frequency of the transmitter/receiver to transmit compared to the magnetic induction method. advantage in terms of distance. However, since the resonant frequency and the energy transmission frequency of the transmitting and receiving coils must be made the same, the size of each coil must be made larger than that of the magnetic induction method in order to secure a high quality factor of the resonator, and the coil structure is complicated and However, it has the disadvantage of being sensitive to the surrounding environment.

The MagMIMO technology proposed by MIT transmits to a receiver within an effective distance with maximum efficiency by increasing self-resonant coupling in a desired direction. When the charger detects a device to be charged, it transmits power in the form of a magnetic field beamforming. Not only is it possible to charge at a distance more than six times greater than the 45cm distance supported by the wireless charging standard Qi 12, but it also has the advantage of being able to adaptively send power to the receiving end even when the receiving end moves. In addition, it is a technology capable of forming a magnetic field beam in an arbitrary direction by controlling the magnitude and phase of six transmitter input signals, and is a wireless power transmission technology for more than six smart and IoT devices.

In addition, the power feeding device 100 according to an embodiment of the present invention may be configured to enable wireless power transmission of a microwave method or wireless power transmission of a laser method. However, the microwave method has problems such as overcoming distance and harmful effects to the human body, and the laser method has problems such as high-power lasers that are harmful to the human body due to high energy density. It may be desirable to use a magnetic induction or magnetic resonance method, which has already been commercialized, as it has a disadvantage of being sensitive to .

The integrated marine lantern 110 according to an embodiment of the present invention may be configured in the same form as in FIG. 2B and receives wireless power from the power supply device 100. More precisely, the lantern 110 is operated through the solar cell, but when the climatic conditions are poor, power is supplied from the power supply device 100 to compensate for this. Therefore, in the embodiment of the present invention, it is possible to select and operate a solar cell and a power receiving device corresponding to the power feeding device 100 based on sensing weather conditions or remaining amount of the internal battery unit under specific climatic conditions. In the example, a solar cell and a power receiving device are configured in parallel so that the solar cell is used as a main power source and the power supply device 100 supplements the main power source. Therefore, it can be seen that the solar cell configured in parallel and the power receiving device receiving power from the power feeding device 100 operate in parallel. That is, it always works.

The lantern 110 of FIG. 2B illustrates a hybrid power generation type with a remote monitoring function. The integrated marine lantern 110 according to an embodiment of the present invention includes a lantern 111, a main body 112, a coupling part (not shown) and a remote terminal part (not shown) as shown in FIG. 2B. can do.

The light unit 111 includes a lamp, an optical cover accommodating the lamp, and a protective cover covering the top of the optical cover.

The main body part 112 has an upper part supporting the light part 111, a frame having an outer surface coupled to the lower part of the upper part to collect sunlight and generating electric energy, and an outer surface on which a solar cell is mounted, and a lower part of the frame It may be coupled to and may include a lower piece for supporting and supporting the light portion 111, the upper piece, and the frame.

The coupling part is provided on one side of the main body part 200 and is provided for electrical connection with an alternative energy supply source 600 that generates electrical energy by solar light, wind power, wave power, or tidal power generation.

In addition, the remote terminal unit is electrically connected to the lamp, the solar cell, and the alternative energy supply source 113 to communicate remotely with the terminal of the control room or manager, together with the remote control of the lamp and the alternative energy supply source 113, the lamp and the solar It is possible to monitor real-time operating conditions of the cell and the alternative energy supply source 113 .

Of course, the present invention can be applied to the above embodiments, and also to the following various embodiments. First, the lantern 111 according to the present invention is supported by a lantern support 115 formed on a buoy 114 floating on the sea as shown in FIG. 1. Here, the lantern support 115 In addition to the solar cell mounted on the body portion 112 as shown, an alternative energy supply source 113 including a sub-solar cell and a horizontal axis type wind power generator as shown in FIG. 1 (a) may be installed.

At this time, an alternative energy supply source 113 including a sub-solar cell and a vertical axis type wind power generator as shown in FIG. 1(b) may be installed in the lantern support 115 in addition to the solar cell. In an embodiment of the present invention, as another alternative energy supply source 113, a power supply device 100 that wirelessly transmits power through self-generation may be configured.

3 is a circuit diagram constituting the power feeding device of FIG. 1;

As shown in FIG. 3 , the power feeding device 100 of FIG. 1 includes an oscillator 300 , a high frequency power amplifier 310 , an impedance matching unit 320 and a power transmission unit 330 .

Prior to a detailed description, the power feeding device 100 according to an embodiment of the present invention may be configured by being divided into a magnetic resonance method and a magnetic induction method. The magnetic resonance method is similar in configuration to the magnetic induction method, and only a slight difference in the configuration of the power transmission unit 330 can be seen. In other words, the magnetic resonance method may configure the power transmitter 330 as a coil or an antenna coil as seen in FIG. 3, whereas the magnetic induction method configures the power transmitter 330 as a ferrite core 335 such as a transformer. There is a difference in points. In FIG. 3, they are shown in combination, but it can be seen that they are substantially separated. Here, various types of ferrite cores such as rod-shaped, cylindrical, EI-shaped, and horseshoe-shaped cores may be used.

The oscillator 300 generates high-frequency power, that is, a high-frequency signal. The oscillator 300 constitutes an oscillator that generates high-frequency power, that is, an oscillator, and may constitute an R-C oscillator circuit as shown in FIG. 3 . In FIG. 3, the R-C oscillation circuit shows a phase shift oscillator having three phase-advancing circuits in the return path. The phase-advance circuit generates a phase shift between 0° and 90° depending on the frequency. So, at the same frequency, the total phase shift of the three phase-advancing circuits is 180° (each approximately 60° equation). The amplifier has a phase shift of 180° because the signal drives the inverting input. As a result, the phase shift of the entire loop becomes 360°, that is, 0°. If the loop gain AB is greater than 1 at this specific frequency, oscillation starts.

To configure the R-C oscillation circuit, the inverting (+) terminal of the op amp, that is, the amplifier is grounded, and the non-inverting (-) terminal is connected in series with capacitors 1 (C1) to 3 (C3), and resistors 1 (R1) to Resistor 3 (R3) is in parallel with each other. In addition, one terminal of the capacitor 1 (C1) is commonly connected to the output terminal of the OP amplifier, and through this, the output voltage can be fed back to the input unit and provided. In the case of the magnetic resonance method, the oscillator 300 preferably generates a frequency signal of 1 to 15 MHz, that is, a frequency voltage.

In addition, the high frequency power amplifier 310 is connected to the output terminal of the oscillation unit 300 . The high frequency signal generated by the phase shift oscillator of the oscillator 300 is input to the high frequency power amplifier 310 . The high frequency power amplifier 310 amplifies the input high frequency power and outputs it to the impedance matching unit 320 . The high frequency power amplifier 310 according to the embodiment of the present invention constitutes a class B push-pull emitter follower. TR1(Q1) and TR2(Q2), and TR3(Q3) and TR4(Q4) constitute a Darlington TR, respectively, and constitute a cascaded emitter follower. That is, TR1(Q1) and TR2(Q2) constitute an NPN emitter follower, and TR3(Q3) and TR4(Q4) constitute a PNP emitter follower.

More specifically, in the high frequency power amplifier 310, the emitter terminal of TR1 (Q1) and the base terminal of TR2 (Q2) are connected to each other, and the collector terminals of TR1 (Q1) and TR2 (Q2) are connected to each other to generate both It is connected to the power supply voltage (+V) terminal of In addition, the emitter terminal of TR2 (Q2) is connected to the emitter terminal of TR3 (Q3), and the base terminal of TR3 (Q3) is connected to the emitter terminal of TR4 (Q4). Collector terminals of TR3 (Q3) and TR4 (Q4) are connected to each other and configured to be grounded. TR1(Q1) and TR2(Q2) are NPN TRs, and TR3(Q3) and TR4(Q4) use PNP TRs. Zener diode 1 (ZD1) and zener diode 2 (ZD2) are connected in series between the base terminal of TR1(Q1) and the base terminal of TR4(Q4), and the base terminal of TR1(Q1) and the power voltage terminal Resistor 1 (R1) is connected between them. In addition, resistor 2 (R2) is connected between the base terminal of TR4 (Q4) and the ground. In addition, the detailed configuration is the same as in FIG. 3 .

Class B operation means that the collector current flows only 180° during one cycle. For this operation to occur, the Q point is approximately located at the cut-off point of the DC load line and the AC load line. The advantages of class B amplifiers are low current draw and high efficiency. When the TR operates in class B, only 180° of the TR conducts during one cycle, so the half cycle is cut off. To avoid this distortion, two TRs are configured in a push-pull structure. This allows one TR to conduct for half a cycle and the other TR to conduct for the remaining half cycle. That is, the NPN emitter follower conducts the positive half cycle and blocks the negative half cycle, while the PNP emitter follower blocks the positive half cycle and conducts the negative half cycle, and the output voltage is approximately equal to the input voltage. However, the load power of the output terminal of the high frequency power amplifier 310 is increased to the maximum when the peak-to-peak load voltage is equal to the maximum peak-to-peak load voltage (MPP).

The impedance matching unit 320 receives the high frequency power signal amplified by the high frequency power amplifier 310 through the capacitor C7, matches the impedance, and outputs the signal to the power transmission unit 330. A capacitor 7 (C7) connected between an output terminal and the ground is connected between the high frequency power amplifier 310 and the impedance matching unit 320. Capacitor 7 (C7) may operate as an energy source when transmitting power in the power transmission unit 330. In other words, for resonance to occur properly, the potential must be high and stable, and capacitor 7 (C7) is involved in this operation.

Impedance matching is required to transfer maximum power from the power transmission unit 330, and for this purpose, the impedance matching unit 320 matches the load impedance with the characteristic impedance. The characteristic impedance refers to the characteristic impedance of a circuit line. That is, the impedance matching unit 320 matches the impedance between the input terminal and the output terminal. In the impedance matching unit 320, the variable capacitor 1 (C8) and the resistor 4 (R4) are connected in series to the input terminal to be grounded, and the output terminal is connected to the variable capacitor 2 (C9) and the resistor 5 (R5) in series to be grounded. An inductor, that is, coil 2 (L2) is connected between one terminal of capacitor 1 (C8) and one terminal of variable capacitor 2 (C9).

The power transmission unit 330 is composed of a coil 3 (L3) connected between the output terminal of the impedance matching unit 320 and the ground. In this way, when a coil is used for the power transmission unit 330, it means a magnetic resonance method. On the other hand, as seen in FIG. 3, when the coil 3 (L3) is replaced with a ferrite core 335, it means a magnetic induction method. In the magnetic induction method, a magnetic field is generated due to the current generated in the ferrite core 335, and thereby an induced current is generated in the coil of the power receiver side of the integrated marine lantern 110 to be described later, thereby generating an induced electromotive force. do.

FIG. 4A is a block diagram illustrating a detailed structure of the integrated marine lantern of FIG. 1. Referring to FIG.

As shown in FIG. 4A , the integrated marine lantern 110 according to an embodiment of the present invention includes some or all of a power supply unit 400, a control unit 410, and a battery unit 420.

Here, "including part or all" means that some components, such as the battery unit 420, are omitted to configure the integrated marine lantern 110, or some components, such as the power supply unit 400, are used as the control unit 410. ), which can be integrated with other components such as, etc., and will be described as including all to help a sufficient understanding of the invention.

The power supply unit 400 includes a first power supply unit 401 and a second power supply unit 402 . Here, the first power supply unit 401 may include various configurations for processing voltage caused by solar cells or wind power. In addition, the second power supply unit 402 operates in parallel with the first power supply unit 401 to receive power wirelessly transmitted from the power supply device 100 of FIG. 1 . In other words, the first power supply unit 401 generates voltage using eco-friendly power generation equipment and uses it, but power may be insufficient depending on weather conditions. It can be seen as making up for the power shortage. The detailed configuration of the second power supply unit 402 will be further discussed later.

The controller 410 is in charge of controlling the power supply unit 400 and the battery unit 420 of FIG. 4A. For example, the control unit 410 sums the current (or charge) provided from the first power supply unit 401 and the current provided from the second power supply unit 402 and supplies the current to the battery unit 420 . Since current is the flow of charge, it can be expressed as the amount of charge of the size of the current. Therefore, the battery unit 420 always has stable power regardless of weather conditions for operating eco-friendly power generation equipment.

The battery unit 420 always has stable power under adverse weather conditions through the first type of power and the second type of power provided from the power supply unit 400 under the control of the control unit 410, and its power is shown in FIG. It can be used to operate the lighting unit 111, that is, a light emitting element such as an LED. Accordingly, it can be seen that the integrated marine lantern 110 according to the embodiment of the present invention can be stably operated at all times.

FIG. 4B is a circuit diagram of a second power supply unit of FIG. 4A.

As shown in FIG. 4B , the second power supply unit 402 of FIG. 4A may include a power receiver 402_1, a high frequency rectifier 402_2, and a power converter 402_3.

As mentioned above, the power receiver 402_1 is composed of a magnetic resonance method or a magnetic induction method. The magnetic resonance method may be configured corresponding to the magnetic resonance method of the power feeding device 100, and the magnetic flow method may also be considered to be configured corresponding to the magnetic induction method of the power feeding device 100. If the ferrite core 402a is configured instead of the coil, it corresponds to the magnetic flow method.

The power receiver 402_1 configures a resonant coil L1 and an antenna coil adjacent to the resonant coil L1, that is, coil 2 (L2) to configure the magnetic resonance method. Since the magnetic resonance or resonance method is a method of transmitting energy, that is, power, using a magnetic resonance shape between coils, the antenna coil (or power supply coil) L3 of the power transmitter 330 of the power supply device 100 of FIG. 3 and the power receiver Power is transmitted by adjusting the wavelength, that is, the frequency, so that the antenna coil (or collector coil) (L2) of (402_1) resonates in the magnetic field. It is disposed close to (L2) and the angle can be adjusted so that power is received in a desired direction. When a magnetic field having the same frequency as the resonant frequency of the collecting coil L2 is continuously generated in the power supply coil L3 of the power transmission unit 330, more induced current is formed in the collecting coil L2 due to a resonance (or resonance) phenomenon. As a result, more energy can be transmitted, which increases the power transmission efficiency.

The high frequency rectifier 402_2 constitutes a full-wave rectification circuit with depletion type MOS FETs HVM3 and HVM4. In addition, two depletion type MOS FETs HVM1 and HVM2 connected in series to the output terminals constituting the loads RL and CL are respectively configured. In order to construct a rectifier circuit, it is preferable to use a depletion type MOS FET in high-frequency rectification because the rectification performance is inferior in the case of a general diode (eg, energy cancellation). In addition, since virtual power (or screen power) is generated by the full-wave rectification circuit, the depletion type MOS FETs HVM1 and HVM2 configured at the front end of the load stage serve to offset and return the virtual power. In addition, HVM5 and HVM 6 connected in parallel to capacitors C1 and C2, respectively, serve as diodes so that stable voltages can be charged to capacitors C1 and C2, and provide bias voltage sources. Accordingly, the power generated in the current collector coil L2 is full-wave rectified by the depletion type MOS FETs HVM3 and HVM4 of the high frequency rectifier 402_2 and delivered to the load capacitor CL.

In the depletion type MOS FET, the source (S) terminal is used in contact with the substrate. The gate terminal of depletion type MOS FET 5 (HVM5) is connected to the gate terminal of depletion type MOS FET 4 (HVM4), and the gate terminal of depletion type MOS FET 6 (HVM6) is connected to the gate terminal of depletion type MOS FET 3 (HVM4). electrically connected to And, one side of the current collector coil (L2) is electrically connected to the gate (G) terminal of the depletion type MOS FET 4 and 5 (HVM4, HVM5) and at the same time connected to the drain (D) terminal of the depletion type MOS FET 2 (HVM2) The other side of the current collector coil L2 is electrically connected to the gate terminals of the depletion type MOS FETs 3 and 6 (HVM3 and HVM6) and at the same time connected to the drain terminal of the depletion type MOS FET 1 (HVM1). Since the connection relationship between other elements is well shown in FIG. 4B, it is intended to be substituted therefor.

According to the configuration described above, the high frequency rectifier 402_2 full-wave rectifies the power generated in the current collecting coil L2 to charge a constant charge in the load-side capacitor CL of the high frequency rectifier 402_2. It can act as a smoothing circuit. Since the load resistor RL is connected in parallel to both ends of the load-side capacitor CL, the voltage across both ends of the load resistor RL is equally applied to both ends of the load-side capacitor CL.

In addition, the power converter 402_3 is connected to the output terminal of the high frequency rectifier 402_2. The power converter 402_2 includes a DC-DC converter, and accordingly, the voltage rectified by the high frequency rectifier 402, more precisely, the DC voltage applied across the load-side capacitor CL of the smoothing circuit is leveled up and output. It can be.

In addition to the above, since the power receiver 402_1, the high frequency rectifier 402_2, and the power converter 402_3 of FIG. 4B can be configured in various ways and perform various operations accordingly, other details I would like to replace it with the previous contents.

5 is a flowchart illustrating a driving process of the integrated marine lantern of FIG. 1;

Referring to FIG. 5 together with FIG. 1 for convenience of description, the integrated marine lantern 110 according to an embodiment of the present invention supplies a first type of power from a first power supply unit (S500). Here, "first type of power" may mean power generated by eco-friendly power generation equipment such as solar light or wind power.

In addition, the integrated marine lantern 110 receives power wirelessly transmitted from the power supply device 100 in a second power supply unit operating in parallel with the first power supply unit to supplement when the first type of power is insufficient ( S510). Here, the wireless power transmission may be performed by a magnetic induction method or a magnetic resonance method. The circuits of the magnetic induction method and the magnetic coupling method are composed of separate boards and can be used selectively according to circumstances, and can be configured to be inserted into and removed from the slot as a card type. Of course, since it is possible to configure circuits for wireless power transmission in different ways on one substrate and selectively operate by a toggle switch or remote control, in the embodiment of the present invention, any one type is particularly suitable. will not limit

The controller of the integrated marine lantern 110 may perform a charging operation by providing power from the first power supply unit and the second power supply unit to the battery unit mounted therein (S520).

In addition, the control unit may output power charged in the battery unit to operate a light unit such as an LED light emitting element constituting the integrated marine lantern 110.

According to the above operation, even in adverse conditions without sunlight or wind power, that is, even when the first power source is not generated at all, the second power source operates the light unit so that the power of the marine integrated light 110 is stably operated. can do.
