Abstract

The invention relates to a light emitting diode and a light emitting diode package. A light emitting diode includes a first light emitting region and a second light emitting region each comprising a first conductivity type semiconductor layer, a second conductivity type semiconductor layer and an active layer interposed between the first conductivity type semiconductor layer and the second conductivity type semiconductor layer, an ohmic reflective layer disposed on the second conductivity type semiconductor layer of each of the first and second light emitting regions, and a first pad metal layer separated from the ohmic reflective layer and electrically connected to the first conductivity type semiconductor layer of each of the first and second light emitting regions, wherein the second light emitting region surrounds the first light emitting region.

Description

technical field [0001] The invention relates to a light emitting diode, in particular to a light emitting diode comprising a plurality of light emitting regions. Background technique [0002] Light-emitting diodes (LEDs) are solid-state light-emitting elements that convert electrical energy into light. Light emitting diodes are widely used as light sources in backlight units, lighting devices, signal indicators, large displays, and the like. [0003] The light emitting diode according to the prior art may include a plurality of light emitting units, however, the light emitting diode according to the prior art has a structure in which the plurality of light emitting units are arranged up and down or left and right. In the light emitting diode having the above structure, the control of the directivity angle by controlling the driving of the plurality of light emitting units cannot be effectively performed. Furthermore, since each of the plurality of light emitting units has ...
