description The utility model discloses a LED light emitting device and drive circuit thereof. This LED drive circuit is used for driving the LED unit, includes: rectifier unit, drive arrangement. This drive arrangement includes: first module and the second module, this first module includes: LED driver chip, this the second module includes: prevent stroboscopic unit and discharge cell, this LED unit is connected to this discharge cell one end, and the other end is connected with this LED driver chip's input, should prevent that the stroboscopic unit was used for preventing that the stroboscopic from appearing in this LED unit, should prevent stroboscopic unit and this discharge cell parallel connection, and this discharge cell releases the remaining electric energy of this LED unit and stores into when closing this LED unit should prevent the stroboscopic unit. The utility model discloses a LED illuminator and LED drive circuit not only can eliminate the stroboscopic of LED unit, and the electric energy of remaining in the time of still can closing the LED unit is saved, and is energy -concerving and environment -protective.
