METHOD FOR CONTROL OF LIGHT FLUXES OF LED LUMINARIES IN BUILDING AND STRUCTURES ARCHITECTURAL ILLUMINATION SYSTEM Russian patent published in 2015 - IPC H05B37/02 F21V8/00 

FIELD: electricity.

SUBSTANCE: invention is related to electric engineering and may be used in architectural lighting and illumination control circuits. In the method for control of light fluxes of LED luminaries in a building and structures illumination system, which consists in the provision of a required astronomical time for the commencement and completion of LED luminaries operation by the master controller through a process controller in compliance with preset charts, record and/or correction of operating scenarios is made from the control room through the master controller for m LED luminaries in n process controllers, at that m≥n, and the performance of the operating scenarios is controlled for each LED luminary, whereat in the operating scenario for each LED luminary discreteness for time-variable control and the light flux fraction is preset for each discretisation interval, at that the change in the light flux for each LED luminary is carried out due to the pulse-width modulation and stabilisation of the current consumed by the LED luminary and/or supply voltage of the LED luminary, and n process controllers are synchronised by means of the master controller by periodic or nonperiodic setting of the process controllers to the initial state.

EFFECT: expanded functionality at the simultaneous simplification of the method realisation and improved reliability of control for the light fluxes of LED luminaries.
