LIGHTING FIXTURE FOR VISIBLE LIGHT COMMUNICATION AND VISIBLE LIGHT COMMUNICATION LIGHTING SYSTEM PROVIDED WITH THE SAME

摘要

PPROBLEM TO BE SOLVED: To provide a lighting fixture for visible light communication whose optical output is hardly decreased and which hardly gives an adverse effect on a lighting environment and to provide a visible light communication lighting system provided with the same. PSOLUTION: The lighting fixture 2 for visible light communication provided with a light source 3 and a switching control unit 4 for controlling switching of the light source 3 on the basis of communication information, includes a human sensor 5 and carries out visible light communication for a prescribed time after the human sensor 5 transmits its sensing signal. Further, a sensing range 6 of the human sensor 5 is overlapped with a transmission range 7 of the visible light communication. The visible light communication lighting system furthermore includes a receiver 8 with a decoding section 9 for decoding the signal transmitted from the lighting fixture 2 for visible light communication.
