LED underwater lights operated by wireless power transmission (LED underwater lights operated by wireless power transmission)

The present invention relates to an LED underwater, and more particularly, to an LED light fixture which is attached to a ship or a yacht outside a hull of a ship or a yacht, ≪ RTI ID = 0.0 > LED < / RTI >

Instead of supplying power to an electric or electronic device by transferring power using an existing power cable, the electric power is transmitted to the device by radio, that is, the electric energy is converted into an electromagnetic wave capable of wireless transmission The power transmission method is referred to as wireless charging, and technologies using wireless communication such as wireless Internet or wireless keyboard are common, but all of these devices are powered by their own batteries. Charging the batteries used in these devices wirelessly was not easy to imagine until a few years ago, but smart phones already have wireless charging technology in place.

The wireless power transmission, which is a technology to transfer electric energy to electromagnetic waves and transmit energy to the load wirelessly without cables, is divided into two types, magnetic induction using electromagnetic induction and magnetic resonance using magnetic resonance (resonance). The basic principle is to start the electric power by flowing the electric power to the coil. When a strong electric current is applied to the coil, the magnetic force is generated. When the other coil is brought close to the coil, the electric current is transmitted to the coil. .

The magnetic induction method is a technique using an electromagnetic induction principle in which a magnetic field is generated in a coil of a power transmitting section and the magnetic field is induced in a secondary coil of the receiving section to supply a current. The magnetic induction method has a problem in that the efficiency is drastically reduced to such an extent that power is hardly transmitted if the power transmission efficiency is 90% or more and the power transmission efficiency is over 90% .

The magnetic resonance method uses a principle of generating a magnetic field that oscillates at a resonant frequency in a transmission coil so that energy is concentratedly transmitted only to a receiving coil designed with the same resonant frequency. By using a frequency of several MHz to several tens MHz, It is a technology that transmits power by resonance. The magnetic resonance method is a technique which can overcome the short distance limit of the electromagnetic induction method and can transfer the energy with a high efficiency from a longer distance. Since the energy not absorbed by the receiving part coil is radiated into the air, So that the efficiency is high.

As an example of a technology relating to a wireless charging device, Patent Registration No. 1197579 entitled " Spatial Adaptive Wireless Power Transmission System and Method using Attenuation Wave Resonance "discloses a self-induction type in which two self- resonant coils are added between a source coil and a load coil And both magnetic induction and magnetic resonance phenomena are utilized. However, the components causing the magnetic resonance phenomenon use a closed circuit composed of a coil and a capacitor for relaying transmission and reception, so that the circuit configuration is complicated and a circuit for implementing the radio power in the middle is included, There is a disadvantage that unnecessary energy loss can be caused.

In addition, a public utility model No. 2015-2095 entitled "electronic device equipped with a wireless charging device" includes a battery charger inside a main body of an electronic device, And the terminal protrusion formed in a shape corresponding to each other is fitted to the terminal protrusion so that the battery charger is charged. Therefore, there is a problem that the electronic apparatus can not be charged when the electronic apparatus is away from the transmission module. There is a problem that it can not be used for an electric or electronic device.

On the other hand, as the income level increases, the yacht market, which is a part of leisure, is growing in Korea and a market of 20 billion won annually is being formed. However, until now, the landscape of the lower part of the yacht has been drilled in the lower part of the hull, but the perforated part is always immersed in seawater, so even if the waterproofing is thoroughly done, There is a great deal of problems such as the necessity of lifting the hull in order to repair or replace the scenery, and there is a lot of difficulty in maintenance, The same technique has the problem that it can not be applied when a light is to be installed in the water such as a yacht, a ship, or an aquarium.

Since the LED underwater according to the present invention is not supplied with power for illumination through a power cable but is wirelessly transmitted, the transmitter 31 and the receiver 35 constituting the illumination device 30 are separately installed, The power source unit 20 for supplying power to the transmitter 31 is a battery or an external power source. The transmitter 31 is installed inside the hull 10 and the receiver 35 is installed outside the hull 10 and is wirelessly transmitted to the ship 10 or the yacht 10 The transmitter 31 and the receiver 35 may be attached to the inner side and the outer side wall of the ship 10, respectively.

   Since the transmission of power from the transmitting unit 31 to the receiving unit 35 is performed wirelessly, the ship 10 must be made of FRP, carbon fiber, wood, glass, etc. instead of a metal material. In the specification of the present invention, the term 'hull' includes not only a hull of a ship or a yacht but also a glass wall constituting an aquarium, and includes any member capable of attaching the transmitter 31 and the receiver 35 of the illumination apparatus Leave.

The casing 311 and the housing 351 are made of stainless steel, aluminum or plastic. Stainless steel is heavy and expensive, so it is preferable to use aluminum which is light and relatively inexpensive. Is weak against water and salt water. Therefore, when using aluminum material, it is coated with carbon or coating on the outer circumferential surface which is in contact with water and moisture or salt water, thereby improving durability, corrosion resistance and heat radiation performance, .

The PCB substrate 352 is attached to an inner space formed in a portion facing outward at the time of installation and the LED device 353 is mounted.
