Abstract

The invention discloses a ship LED lighting system and a soft start device thereof. The soft start device of the ship LED lighting system comprises a first circuit breaker and a zero-crossing triggermodule; when a power supply end does not supply power, the zero-crossing trigger module is in an open circuit state; when the power supply end starts to supply power, the zero-crossing trigger moduleis used for detecting whether the voltage of the power supply end crosses zero or not, and if yes, the zero-crossing trigger module is conducted to supply power to an LED lighting device. The ship LEDlighting system and the soft start device thereof can effectively inhibit the larger impact current generated by the LED lighting system in the starting process by the soft starting technology; the economy and reliability of the system and the device can be ensured to be unaffected under the condition that the current ship lighting power distribution design standard and the current technology state are not changed; and moreover, the maximum using quantity of the LED lighting devices in each lighting branch can be increased, so that the using quantity of cables built by the system is reduced,and the using cost is further reduced.

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...
