Description

technical field [0001] The invention relates to LED circuit technology, in particular to a power supply system suitable for mobile lighting equipment and its implementation method. Background technique [0002] With the development of electronic technology, portable and durable lighting products are becoming more and more extensive. The use of lithium batteries for standby power supply and USB power adapter charging power supply is a development direction of portable lighting products. The output voltage and current of the conventional USB power adapter is 5V / 1A; the charging current of the lithium battery is controlled at 400MA. So when the USB power supply is powered, only 60% of the maximum power is used for lighting output. The key parameters such as light efficiency and luminous flux of the lighting equipment are greatly restricted. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above prior art, and pr...
