Wireless obstruction beacon
The present disclosure is directed to examples of a warning beacon light. In one embodiment, the warning beacon light includes at least one light redirection component, a plurality of light emitting diodes (LEDs) positioned relative to the light redirection component such that light emitted from the plurality of LEDs is collimated to within a predefined range relative to a light emitting axis, and a wireless power transfer system coupled to the plurality of LEDs to provide power to the plurality of LEDs.
1. A warning beacon light, comprising:
at least one light redirection component;
a plurality of light emitting diodes (LEDs) positioned relative to the at least one light redirection component such that light emitted from the plurality of LEDs is collimated to within a predefined range relative to a light emitting axis; and
a bottom housing located below the at least one light redirection component, wherein the bottom housing comprises:
a wireless power transfer system coupled to the plurality of LEDs to provide power to the plurality of LEDs; and
a power converter coupled to the wireless power transfer system to convert a high frequency electromagnetic flux received from the wireless power transfer system to a direct current (DC) power supply, wherein the power converter comprises a rectifier in a two phase or bridge configuration and a power reservoir and operates at frequencies between 100 kilohertz (kHz) to 500 kHz, the power reservoir comprising a capacitor to transform the high frequency electromagnetic flux into the DC power supply.
2. The warning beacon light of claim 1 , wherein the plurality of LEDs is arranged relative to the at least one light redirection component and powered by the wireless power transfer system to emit an amount of light that is in accordance with a standard.
3. The warning beacon light of claim 1 , wherein the warning beacon light is coupled to a structure that is at least 100 feet tall.
4. The warning beacon light of claim 1 , wherein the wireless power transfer system comprises a receiver coil in a bottom housing, wherein the receiver coil receives power, via an electromagnetic flux, from a transmitter coil in a base coupled to a structure.
5. The warning beacon light of claim 1 , further comprising:
a wireless transceiver to transmit operational data of the warning beacon light and receive control signals.
6. The warning beacon light of claim 1 , further comprising:
a controller to control a power transfer from the wireless power transfer system to the plurality of LEDs and to control monitoring of operations of the plurality of LEDs.
7. The warning beacon light of claim 2 , wherein the standard comprises at least one of: a federal aviation administration standard, an international civil aviation organization standard, or an international association of marine aids to navigation and lighthouse authorities standard.
8. A method for installing a warning beacon light, comprising:
coupling a base with a wireless transmitter coil to a portion of a structure where the warning beacon light is to be installed to warn aircraft;
erecting the structure at a desired location;
coupling the warning beacon light to the portion of the structure after the structure is erected at the desired location, wherein the warning beacon light is positioned to place a wireless receiver coil in the warning beacon light to be less than or equal to 30 millimeters from a wireless transmitter coil in the base; and
generating an electromagnetic flux between the wireless transmitter coil and the wireless receiver coil to generate power to operate a plurality of light emitting diodes in the warning beacon light.
