Light emitting module and lighting unit including the same

A light emitting module, comprising:

• a body;
• first to Mth (wherein, M is an integer of 2 or greater) light emitting devices provided on the body to be spaced apart from each other;
• a rectifier rectifying an alternating current signal applied from the outside to convert the alternating current signal into a ripple signal;
• and
• a turn-on controller controlling the first to Mth light emitting devices to turn on according to the level of the ripple signal,
• wherein an mth (1≦m≦M) light emitting device among the first to Mth light emitting devices comprises first to Nth (wherein, N is an integer of 2 or greater) light emitting cells connected to each other in series,
• wherein the turn-on controller simultaneously turns on or turns off nth light emitting cells of the first to Mth light emitting devices, and
• wherein the first to Mth light emitting devices are provided on the body to be spaced apart by different distances from each other.
