Patent attributes
Disclosed are an apparatus and a method for visible light communication, which apparatus uses an illuminator equipped with a plurality of light sources, so that the apparatus can be used for illumination, as well as for visible light communication. The visible light communication apparatus includes an illuminator for generation of the illumination light, the illuminator including a plurality of light sources with luminescence center wavelengths on mutually different visible regions; a communication amount adjuster for receipt of the plurality of communication data signals, and generation of each dummy data so that data to be transmitted through each of the plurality of LEDs has an equal communication amount; and a modulator for receipt of the plurality of communication data signals and their corresponding dummy data, and modulation of the received communication data signals and their corresponding received dummy data into driving signals for a plurality of LEDs configured as a light source.
