Abstract

The invention provides a wireless power supply method and system and a coupling inductance coil thereof. The method comprises the following steps of: optimizing wire material quality, inductance value, wire diameter, number of turns, inner diameter and outer diameter of the coupling inductance coil; debugging to finally find a set of optimized system parameters so as to match with a control algorithm. Through the adoption of the method provided by the invention, the remote power supply and large-power high-efficiency transmission can be realized, the electromagnetic shielding effect is good, the light adjustment is supported, and the installation is convenient; and the coupling inductance coil is especially suitable for a wireless electric energy emission device capable of supplying power to large-power lighting lamp products, and a wireless power supply system of a receiving device using the wireless electric energy.

Description

technical field [0001] The present invention relates to wireless power supply technology, in particular, to a lighting method and system based on wireless power supply and its coupled inductance coil, and in particular to a wireless energy transmitting device capable of supplying power to high-power lighting products, and a device for applying the wireless energy Wireless power supply system for receiving devices. Background technique [0002] Most of the existing buildings in the world use aluminum curtain walls or similar structures on their facades. At that time, these buildings were not illuminated for various reasons when they were built, or because of quality problems with lamps after lighting. Or the problem of failure of traditional light sources leads to the failure of the current facade lighting system, and the current reconstruction schemes in the lighting market all need to lead power lines or signal lines from the interior of the curtain wall to the outside of t...
