Abstract

The invention provides a method and device for realizing information transmission by taking visible light as a medium, relating to the technical fields of lighting, power supply, integrated circuits, optics, communication, signal processing, network, locating and the like. The method comprises the following steps of: modulating bit information having digital signals into transmission signals by a pulse signal modulator, driving an LED (light-emitting diode) by a circuit to emit light signals, receiving the light signals emitted by the LED by a photon detector, and restoring the bit information by demodulating and balancing. Compared with a traditional information transmission means, the invention has the advantages of environment friendliness, quickness, wireless operation and safety.

Description

technical field [0001] The invention relates to technical fields such as illumination, power supply, integrated circuit, optics, communication, signal processing, network, and positioning. Background technique [0002] Lighting lamps have developed from incandescent lamps, fluorescent lamps, and energy-saving lamps to today's new generation of solid-state LED lighting. White lighting LEDs have significant advantages such as high intensity, high efficiency, small size, low cost, easy maintenance, and no pollution. With the green Pollution-free energy and energy saving have become global hot topics, white lighting LED will gradually replace the traditional lighting with incandescent and fluorescent lamps. At the same time they can be used to make multifunctional display panels, TV screen displays, vehicle headlights, taillights, and traffic lights. For example, more and more vehicle manufacturers have recently begun to equip new vehicles with white LEDs. Traffic control and ...
