Description

technical field [0001] The invention relates to a ship light, in particular to a ship-used high-efficiency embedded LED strip light. Background technique [0002] Existing ship lights usually include an LED light source, a driving power supply and a radiator. The driving power supply is an important part that affects the reliability and adaptability of the LED light source, so higher requirements are put forward for the efficiency, life and cost of the driving circuit, as well as the protection function. Specifically, 1. The drive circuit must not only have a certain forward current output close to the constant current required by the LED, but also have a high conversion efficiency. The electro-optical conversion efficiency is an important factor for semiconductor lighting, otherwise it will be lost. Advantages of LED energy saving. 2 In terms of LED life, although the life of a single LED itself is as long as 100,000 hours, it must be used with a power conversion circuit....
