Description

Changeable color light fish light driver

The present invention relates to a driving circuit for a fish lamp, and more particularly, to a fish lamp driver capable of changing color light.

Generally, traditional fishing lights use incandescent lamps. However, incandescent lamps are high energy-consuming lamps, which do not meet the current trend of low-carbon and environmental protection in society. Therefore, LED fish-collecting lamps have emerged accordingly. LED manufacturers at home and abroad are eager to enter this. In the market, most of the LED lamp driving circuits use switching power supplies, and the switching power supplies still need to cooperate with high-frequency transformers. The power output of the diesel generator of a general fishing boat reaches a kilowatt level, and generally high-frequency transformers cannot pass Test items such as inductance, leakage inductance, withstand voltage, insulation resistance, etc., and high-frequency transformers also have missing weight and bulk;

In addition, fishing boats are often not limited to catching a single type of fish after the voyage. However, different types of fish need different colors of fish lights to have a better attraction.
