Abstract
There is disclosed a visible light communication technology capable of intuitively recognizing a transmission speed, an alignment status, a communication status, or a transmission rate. A visible light communication apparatus according to an embodiment of the present invention includes: a light source selecting unit selecting at least one light source of a plurality of light sources generating lights having different wavelengths by considering intuitive information distinguished depending on a wavelength in a visible light band; and a visible light communication unit performing visible light communication by at least one selected light source to allow the intuitive information to be recognized by a color corresponding to at least one selected light source. Accordingly, a user using the visible light communication can intuitively know an optimal communication status or transmission speed.
