Abstract
An optical-information transmitting, lighting apparatus 2 is installed in a place where a lighting apparatus of the existing type for applying light generally used is provided. The lighting apparatus 2 comprises an illumination light source 4 for applying light and an information-transmitting unit 5 for transmitting optical information. A person who may receive information from the lighting apparatus 2 has a mobile terminal 3, which receives the optical information transmitted from the information-transmitting unit 5. Since the lighting apparatus of the existing type is widely used in our living space. Hence, the optical-information transmitting, lighting apparatus 2 can convert every place where an existing type lighting apparatus is used, into an optical communications space.
