The known method of decorative lights (Patent RF №2247897, F21S 10/00, 2000), which consists in the formation of three multi-colored light from sources located inside the luminous object and the power from different generators with time-varying triangular law and shifted in phase voltages, wherein the object is illuminated with lamps, built-in elements of the luminous object, refracting light, each lamp consists of three different color light sources and each light source receives power from your generator with a time-varying voltage, and luminous further object is illuminated by external lights of three different colors of light sources based on LEDs, and each light source receives power from a generator with a time-varying voltage. Each generator is connected to the light sources with different radiation spectrum.
The disadvantage of this method is the complexity of the implementation due to the need to use specialized generators, and the inability to quickly change backlighting scenarios.
Closest to the claimed method �is "Method and system for controlling electrical equipment in particular the lighting system" (Patent RF №2474030, H02J 13/00, H05B 37/02, 2011), adopted as a prototype, namely, the Central controller through master controller required astronomical time of the beginning and end of led lights in accordance with the specified tabular schedules.
The disadvantage of this method is due to its limited functionality, and implementation complexity.
The technical result of the proposed method is to increase functionality while simplifying the implementation of the method, as well as improving the reliability of the control light flow led lights.
The technical result is achieved in that in the method of controlling light flow led luminaires in the system architectural illumination of buildings and structures, namely, the Central controller through master controller required astronomical time of the beginning and end of led lights in accordance with the specified tabular charts, from the dispatching is made through a Central controller for recording and/or correction of scenarios m led lights in n: controllers, where m≥n, and supervise the execution of scripts R�bots each led luminaire while in the scenario of each led lamp set regulation resolution in time and equity value of the luminous flux from its maximum value at each discretization step, and changing the luminous flux of each led lamp is carried out by pulse-width adjustment and stabilization of the current consumed by the led lamp, and/or voltage of the led lamp, and n synchronize controllers with the Central controller through periodic or aperiodic setup controllers to its original state.
Fig.1 shows a block diagram of a device that implements the proposed method of controlling light flow led luminaires in the system architectural illumination of buildings and structures.
The device comprises a dispatch unit 1, connected by bidirectional communication channels shared with a unique identification address via the Central controller 2 with n control controllers 31÷3n.
The respective outputs of each of the master controller 31÷3nconnected to the inputs of the respective led modules 41÷4mincluded in the managed data controller group. All groups n. The number of St�todiode modules 4 1÷4min the group of each of the master controller 31÷3nmay not exceed the number of control inputs of the master controller.
All led modules 41÷4mstructurally identical and include a regulating unit 5k(k=1÷m), first input of which is the input of the led module 4kconnected to the output through the current meter 6kthe entrance led lamp 7k. To the second input of the regulating unit 5kconnected the output of the voltage meter 8kconnected the input directly to the output of the regulating unit 5kto the third input of which is connected to the second output of the current meter 6k.
The method is as follows.
In the initial state, pre-on command from control center 1 Central controller 2 produces a record or correction of preset scenarios of led lights 71÷7min controllers 31÷3nand forms management controllers 31÷3nthe command to run scripts to work. Scenarios of led lights 71÷7mmay be different in the General case.
The Central controller 2 through controllers 31÷3nprovides a desired astronomical start and head�of Rhenia of led lights 7 1÷7mfor example , in accordance with the specified tabular graphs of sunrise and sunset for a given latitude or by applying a light barrier.
Each led module 41÷4mthe regulating unit 5kproduces a pulse-width regulation and stabilization of the current consumed by the led lamp 7kor/and voltage of the led lamp 7kin accordance with a given scenario the variation in time of the luminous flux of the led lamp, functionally associated with the magnitude of the supply current or the supply voltage. This is required consistent dynamic backlight of a building or structure where the led lamps are installed.
Controllers 31÷3ncontrol the execution of scenarios each led lamp is included in a managed data controller group, and transfer the information to the Central controller 2, which allows to identify and to eliminate failures led fixtures and malfunction in the led modules 41÷4m.
In the scenario of each led lamp set regulation resolution in time and equity value of the luminous flux from its max�Noy values at each cycle to obtain the desired smoothness of change of the light fluxes in the system of architectural lighting.
Scenarios of change in time of the luminous flux of led lamps can be corrected quickly by hand or in an automatic mode that allows the dark comprehensively beat, i.e., to emphasize the luminous flux of illuminated architectural solutions of buildings or structures equipped with a system of dynamic architectural lighting.
To exclude a significant desynchronization of work: controllers 31÷3ndue to the difference in their performance is most just, for example, to produce a periodic or aperiodic (in a natural pause in the scenarios of led lights) setting: controllers 31÷3nin the initial state, i.e. cyclically relieving accumulating system error.
Thus, implementation of the proposed method allows to extend the functionality while simplifying the implementation of the method and increase the reliability of the control light flow led lights.
