Abstract

A light emitting device is provided. The light emitting device may include a plurality of light emitting array modules each including at least one light emitting element, and a common driving module commonly connected to the plurality of light emitting array modules and configured to supply an operating voltage to each of the connected light emitting array modules. Each of the plurality of light emitting array modules may include a light emitting module including the at least one light emitting element and an individual driving module configured to receive the operating voltage supplied from the common driving module and output an operating current to the light emitting module based on the received operating voltage.
