Abstract

The invention discloses a ship LED lighting system and its soft start device, the soft start device of the ship LED lighting system, the soft start device includes a first circuit breaker and a zero-crossing trigger module; when the power supply terminal is not powered, the zero-cross trigger module It is in an open circuit state; when the power supply end starts to supply power, the zero-crossing trigger module is used to detect whether the voltage of the power supply end crosses zero, and if so, the zero-crossing trigger module is turned on to supply power to the LED lighting equipment. The invention effectively suppresses the relatively large inrush current generated by the LED lighting system during the startup process through the soft start technology; at the same time, it can ensure the economy and safety of the system and equipment without changing the current ship lighting power distribution design standards and technical status. Reliability is not affected; in addition, the maximum number of LED lighting devices used in each lighting branch can be increased, thereby reducing the amount of cables used in system construction, thereby reducing the cost of use.

Description

technical field [0001] The invention relates to the technical field of circuit design, in particular to a marine LED lighting system and a soft start device thereof. Background technique [0002] With the continuous improvement of energy saving and dimming performance of LED (light emitting diode) lamps, its application proportion in the shipbuilding industry is gradually expanding, and some large passenger ships even use LED lighting equipment on board. [0003] LED lighting equipment generally adopts the direct start method. However, because the power supply matched with LED lighting equipment drives its internal input filter capacitor element, a huge inrush current will be generated due to the charging effect at the moment of power-on. Based on the current design of ship lighting power distribution This will inevitably have an adverse effect on the reliable operation of the lighting system; in addition, in order to avoid the power-off state caused by the huge inrush curre...
