Abstract

The invention relates to a light emitting device and an automotive lighting apparatus including the same. 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.

Description

technical field [0001] The present disclosure relates to a light emitting device including a light emitting module and a driving module and an automotive lighting device including the same, and more particularly to a light emitting device in which a driving module for supplying driving power to a plurality of light emitting modules is divided into A common driver module that can be used in common and an individual driver module provided in each light emitting module. Background technique [0002] Recently, light emitting diodes (LEDs) have been widely used as light emitting modules in various fields including lamps for vehicles. In addition, since organic light emitting diodes (OLEDs) have excellent color reproducibility and fast driving speed compared to LEDs, the use of all OLEDs has increased. [0003] The applications of such lighting modules have been expanded. For example, using light-emitting modules as high-intensity light sources for flashlights, for liquid crysta...
