[ The power output unit 510 is preferably fixed in position so as not to be affected by the rotational motion of the shaft 600. For example, it can be fixed to the ground by a plurality of legs (not shown) extending from the power output unit 510 toward the ground.

The power receiving unit 520 may provide the electric power received from the power output unit 510 through the wireless coil charging system to the LED light source 140. For example, the LED light source 140 and the power receiving unit 520 may be electrically connected by the cable 150 to transmit or receive power.

The power receiving unit 520 may be positioned on the support unit 310 and rotated together with the light source mount 300 when the power source mount 400 is rotated by the power unit 400.

In order to facilitate understanding of the above-mentioned wireless coil charging system, the following description will be given. Wireless charging technology is used in the term of Wireless Energy Transmission (WET) or Wireless Power Transmission (WPT). It converts electric energy (DC power) into radio wave power and transmits it wirelessly within a certain distance . That is, the secondary battery of the electronic device, for example, the battery is contacted through rectification (DC <-> AC) or the battery is charged in a noncontact manner. The wireless coil charging system of wireless charging technology can be classified into a magnetic induction system and a magnetic resonance system according to a power transmission system and a transmission distance, and the present invention can be applied to any one of the above two systems.

The LED light source 140 may be connected to the power source output unit 510 through the wireless coil charging scheme to transmit power to the power source receiving unit 520 and to be electrically connected to the LED light source 140, . When the transmission and reception of the power described above is summarized, power is supplied to the power output unit 510 through a second power supply unit (not shown), and the power output unit 510 outputs power And the power receiving unit 520 may be configured to supply power to the LED light source 140 electrically connected through the cable 150.

The battery 530 may be repeatedly supplied with power from the power source output unit 510 and discharging power to the LED light source 140 And the LED light source 140 and the battery 530 may be electrically connected through the cable 150. [

When the power supply unit 500 and the LED light source 140 are electrically connected to each other through the cable 150, the cable 150 connected to the respective LED light sources 140 is connected to the inside of the hollow light source mount 300 A cable 150 connected to a battery 530 provided inside or on the side of the light source mount 300 or extending along the outer surface of the light source mount 300 passes through a power receiving part 300, And may supply power to the LED light source 140. FIGS. 5A and 5B are schematic views illustrating a method of connecting an LED light source of a lighthouse light source according to an embodiment of the present invention to a power receiving unit and a battery through a cable. Will be described with reference to Figs. 5A and 5B.

Hereinafter, a description will be made of an operation procedure of the light guide for a beacon according to an embodiment of the present invention.

At this time, the LED light source 140 generates a cross- And irradiates light toward the inner surface 120 of the mirror 110 from the focal point of the parabola.

The light irradiated from the LED light source 140 is incident on the inner surface 120 of the mirror 110. Since the vertical cross-sectional shape of the mirror 110 is a parabola, the light incident on the inner surface 120 of the mirror 110, And is parallel to the parabolic axis 125 passing through the focal point of the parabola.
