The present invention relates to an automatic lighting control system and method through a DC power supply, and more particularly, it is easy to manage power for a plurality of LED modules installed and used in buildings, and stable for LED modules having different rated powers. The present invention relates to an automatic lighting control system and method through a DC power supply that guarantees stability and compatibility by supplying power corresponding to the rated power.

As the modernization of the building increases, the size of the building is becoming larger and the current complexes (apartments, villas, officetels, venture towers, etc.) are illuminated around underground parking lots and sidewalks. The lights are installed.

Since the lights are arranged in a large number of lights according to the land security regulations corresponding to the building size, it is required to develop a system for stably supplying power to these multiple lights and for easy maintenance.

The lamp is mainly used incandescent lamps, fluorescent lamps or halogen lamps using AC voltage, but the current life is relatively long, the power consumption is low, the trend of replacing the light emitting diode lamp (LED lamp) to support high brightness.

In such a lighting control system, the main controller 10 transmits a control signal to the SMPS 20 through an AC power line, so that the SMPS 20 controls the brightness of the LED lamp 30 according to the control signal. Although the control signals of the same brightness are transmitted, the SMPSs 20 are different from each other, and thus the reliability of providing uniform brightness is low, and the performance degradation according to the individual lifespan or the use situation also lowers the reliability of the uniformity. There is a problem.

In addition, when the failure of the SMPS 20 is frequently replaced, there is a problem that the management cost increases because the SMPS 20 itself is quite expensive, in particular any one of the LED lamp 30 or SMPS (20) When the discontinued, there is a problem in that the cost burden is doubled because both the LED lamp 30 and the SMPS 20 need to be replaced.

In addition, recently, an integrated bar type LED light 30 is mainly installed in an underground parking lot or a corridor of a building, and some light emitting diodes frequently fail in a BAR type LED light composed of a plurality of light emitting diodes. However, even in such a case, since the replacement of the entire module including the SMPS is required, there is a problem in that the cost is increased and thus waste is generated.
