Description
technical field [0001] The invention relates to the field of electronic technology, in particular to a lighting circuit that can be used for charging a mobile phone. Background technique [0002] In people's daily life, mobile phones have become an indispensable factor and are carried by people. With the diversification of mobile phone functions, its power consumption is also increasing, and users need to charge their mobile phones frequently. Generally, mobile phone charging needs to be connected to the mains through a data cable and a charging head. When there is a power outage, the user is in a situation where there is no mains power or does not carry a data cable, the mobile phone cannot be charged, which brings trouble to the user. Based on this, if the portable device that people often carry can have the function of charging the mobile phone, it will bring great convenience. Contents of the invention [0003] The technical problem to be solved by the present invent...
