These innovative LEDs utilize magnetic resonance coupling technology to illuminate without the need for wires, batteries, or conventional power sources. This breakthrough is achieved through the use of a coil transmitter and miniaturized receiver coils attached to each LED bead. When activated, the transmitter sends energy wirelessly through the air, enabling the LEDs to light up even when obscured by paper or plastic coverings.
The technology behind this remarkable feat allows for non-contact power transmission, consuming a fraction of the energy associated with traditional electromagnetic induction methods. Unlike conventional power sources, the transmitter generates a non-radiative magnetic field rather than electromagnetic waves, ensuring energy transfer at exceptionally low power consumption levels.
The magnetic field generated by this system is comparable in strength to the Earth's natural magnetic field, ensuring safety for both humans and electronic devices. This technology beautifully marries efficiency and safety, offering a low-energy lighting solution that can be applied in various creative and practical scenarios, such as concealed displays or interactive installations.
