发明名称 LED LIGHTING APPARATUS
摘要 Provided is a lighting apparatus. The lighting apparatus may include two or more lighting units each including a plurality of LED groups which sequentially emit light in response to changes of a rectified voltage. The two or more lighting units may include one or more LED groups having the same light emitting sequence but having different light emitting points of time. Thus, current harmonic can be reduced, and power efficiency can be improved.
