Abstract:
A light emitting device driving module may be provided that includes: a light emitter including a first light emitter and a second light emitter connected to the first light emitter; a rectifier which receives an AC power and outputs a rectified voltage; and a controller which receives the rectified voltage from the rectifier and controls on/offs of the first light emitter and the second light emitter in accordance with a magnitude of the rectified voltage. The light emitting device driving module according to the embodiment controls the on/offs of two or more kinds of the light emitting devices by using the AC power, and thus, drives the light emitting device in such a manner as to have a high color rendering index.
