PURPOSE: A visual light wireless communication method and a device for the same are provided to minimize the brightness reduction of a visual light source or a light device which is generated by a code for a communication and a demodulation function. CONSTITUTION: A coding and modulating unit(120) code and modulates each bit of a code which will transmits the code by at least one between a first modulating signal and a second modulating signal. The first modulating signal is for enabling light during a unit time in continuous on state. A second modulating signal is for generating the off/on of light within the unit time or generating on/off modification. A visible light source driving unit(130) drives the light by using a first modulating signal or a second modulating signal. The visible light source driving unit performs visible light wireless communication through the light. |
