ADAPTIVE OUTDOOR LIGHTING SYSTEM Russian patent published in 2024 - IPC F21S2/00 

FIELD: lighting.

SUBSTANCE: invention relates to lighting systems and can be used in creating computerized lighting systems for roads, city streets and squares, which provide comfortable lighting for all road users in the dark, as well as in unfavourable meteorological conditions. Adaptive outdoor lighting system comprises a central controller, a dispatching device connected to it and one or more lighting devices, each of which contains an intelligent control unit, connected to it an illumination sensor, an air temperature sensor and a controlled light-emitting diode lamp. In each lighting device there is additionally installed a sensor of relative humidity of air connected to the intelligent control unit. Intelligent control unit is configured to monitor air temperature, relative humidity and dew point temperature trends, as well as with possibility of comparing current and predicted values of air temperature and dew point temperature, wherein the controlled light-emitting diode lamp comprises at least two groups of light-emitting diodes with different colour temperature, each of which is connected to its own controlled power supply unit.

EFFECT: high reliability of early and optimal change of lighting parameters at threat of fog formation and high energy efficiency of the system.
