Abstract
In a visible light communication system including a transmission device and a receiving device arranged separately in a vertical direction and provided so as to relatively move in a horizontal direction, which transmits data from the transmission device to the receiving device by optical space transmission using visible light, the transmission device includes a first light emitting part outputting visible light, and the first light emitting part has a light source emitting visible light and a correction part correcting the light radiated from the light source so as to uniform a light intensity distribution on a horizontal plane. Even when the transmission device and the receiving device arranged separately in the vertical direction relatively move in a horizontal direction, data can be stably transmitted and received by the optical space transmission using visible light.
