FIELD: electricity.
SUBSTANCE: invention relates to lighting engineering. The invention suggests coded light to ensure improved control over light sources and transmission of data using light sources. Assignment of identification frequency for light sources allows assignment of more unique frequencies, i.e. for unique identification of more light sources in the system. Accessible frequency band is divided into uneven frequency areas and frequency is selected from the set of evenly separated frequencies in uneven frequency areas. Operation of the receiver is based on successive principle and able to analyse higher harmonics of the received light signals. Light components are assessed by groups successively.
EFFECT: improving efficiency in appointment of light source identifiers in the lighting system.
