Problems solved by technology

[0002] Lighting equipment is an indispensable equipment for daily production and life; at present, the existing problems of the existing DC lighting distribution system are: since the DC lighting distribution system is mainly used for household power supply and lighting, there are certain limitations in the application in the industrial field For example, when it is used in a narrow subway lighting distribution room, many large distribution boxes with rectifier modules are required to supply power, and the occupied area does not meet the actual requirements; when the "loop controller" in the power distribution equipment When a certain loop fails, the entire loop controller must be replaced. At this time, all lamps need to be powered off, thereby affecting the overall lighting; from past engineering experience, if the rectifier module and the lamp controller are placed in the same Electric box, the wiring inside the cabinet is very complicated, which will increase the difficulty of manufacturing the distribution box

Abstract

The invention relates to the technical field of direct-current lighting power distribution, in particular to a novel direct-current lighting power distribution system. The system comprises a rectifierpower distribution box, the rectifier power distribution box is electrically connected with two or more dimming control power distribution boxes, each dimming control power distribution box is electrically connected with two or more lamp loop sets, a power electronic device is placed in the rectifier power distribution box, more than two independent dimming modules are placed in the dimming control power distribution box, each lamp loop set comprises a direct-current dimming driving power supply module, and each direct-current dimming driving power supply module is electrically connected withthe corresponding dimming control power distribution box. All power electronic devices are placed in the same large power distribution box (namely the rectifier power distribution box), and more thantwo mutually independent dimming modules are placed in a plurality of small power distribution boxes (dimming control power distribution boxes) in groups, so that internal wiring of a single power distribution box can be reduced, and the total volume of power distribution system equipment can be reduced.
