Abstract

The invention provides an LED (Light-Emitting Diode) lamp based on discrete wireless power supply, which comprises a transmitting coil, a drive circuit, a receiving coil, a receiving circuit and an LED lamp, wherein the transmitting coil generates inductive power through self-resonance; the drive circuit is connected between an external power source and the transmitting coil and drives the self-resonance of the transmitting coil to generate the inductive power according to the power received from the external power source; the receiving coil is opposite to the transmitting coil and is coupled with the transmitting coil through the self-resonance to induct and receive the power in the transmitting coil; the receiving circuit is connected with the receiving coil and receives the power in the receiving coil; and the LED lamp is connected with the receiving circuit and is lightened when the receiving circuit receives the power. The receiving coil is not electrically contacted with the transmitting coil, the short-distance wireless transmission of power is realized through the coupling of the receiving coil and the transmitting coil, and the power received by the receiving coil is supplied to the LED lamp.

Description

technical field [0001] The present invention relates to the technical field of wireless power transmission, in particular to the wireless power transmission technology of LED lamps, specifically an LED lamp based on discrete wireless power supply. Background technique [0002] Wireless energy transmission technology is a new energy transmission technology, that is, a technology in which electrical equipment obtains power from a fixed grid in a non-contact manner. In 2007, scientists at MIT realized medium-distance wireless power transmission by using the principle of electromagnetic resonance, lighting up a 60W light bulb within a distance of more than 2m, and the transmission efficiency reached about 40%. Compared with the wireless power transmission technology proposed in the past, the resonant coupling wireless power transmission has the following essential differences: 1) Compared with the wireless power transmission technology using the principle of electromagnetic indu...
