摘要:
A lighting system (20) comprises a plurality of light units (1, 6, 10, 11), each light unit (1, 6, 10, 11) including a photo sensor (2, 7), a light source (4, 9) and a control unit (3, 8) adapted to operate the light source (4, 9) and to modulate the light emitted by the light source (4, 9) so as to transmit data, wherein the light units (1, 6, 10, 11) are arranged according to a ring topology.
