Description
technical field [0001] The invention relates to a magnetic core, in particular to a FX magnetic core used for an LED transformer. Background technique [0002] The LED lighting drive circuit needs to use a magnetic core with a complex shape. Due to some defects in the design of the previous magnetic core, the magnetic core has leakage inductance during use, which greatly increases the power consumption of the product and reduces the lighting efficiency. In order to solve this problem, the magnetic core can meet the design requirements by optimizing the design of the magnetic core structure. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a magnetic core that can be applied to LED lighting driving circuits and can be manufactured in large quantities at low cost. [0004] The technical solution adopted in the present invention is: a FX magnetic core for LED transform...
