LIGHT-EMITTING DIODE LIGHTING SYSTEM

摘要

The present application discloses a light-emitting diode (LED) lighting system, including: a toroidal transformer comprising a pair of input terminals and a pair of output terminals; and an illuminant comprising an LED circuit; wherein the illuminant is electrically connected to the pair of output terminals of the toroidal transformer. The present application uses a toroidal transformer to simplify a circuit and reduce the number of electronic parts used. On one hand, a service life of a product can be prolonged, and on the other hand, costs can be reduced and a recycling rate is high, which is beneficial to environmental protection.
