Light emitting device and light emitting device package

Abstract

The embodiment of the invention discloses a light emitting device and a light emitting device package. The light emitting device comprises a light emitting structure, wherein the light emitting structure comprises a first conduction type semiconductor layer, an active layer, a second conduction type semiconductor layer, a first electrode, a first electrode layer, a second electrode and an insulating layer, the first conduction type semiconductor layer, the active layer and the second conduction type semiconductor layer are stacked in sequence, the second conduction type semiconductor layer is used as a light-out surface of the light emitting structure, the first electrode is arranged on the surface, which is far from the active layer, of the first conduction type semiconductor layer, the first electrode is electrically connected with the first conduction type semiconductor layer, the first electrode layer is arranged on the surface, which is far from the active layer, of the second conduction type semiconductor layer, the first electrode layer is electrically connected with the second conduction type semiconductor layer, the second electrode penetrates through the light emitting structure and is electrically connected with the first electrode layer, and the insulating layer is arranged between the light emitting structure and the second electrode. By adopting the light emitting device, the electrodes are led out from the bottom of the light emitting device, so that light is prevented from being shielded and absorbed by leading wires, and the light-out rate is increased.

Description

technical field [0001] The invention relates to the field of light emitting devices, in particular to a light emitting device and a package of the light emitting device. Background technique [0002] The sustainable use of energy has always been the focus of social attention. Scientists are developing various low-energy, high-performance light-emitting tubes to alleviate the current energy pressure. Among them, light-emitting diodes (Light-Emitting Diode, referred to as LED) are highly efficient The effect of energy saving is outstanding, and it is constantly being popularized in various fields of life. [0003] In the prior art, light-emitting devices such as LED light-emitting chips are usually lead from the light-emitting surface to connect the positive and negative electrodes. However, the lead itself will absorb and block the light emitted by the light-emitting device, affecting the light extraction rate of the light-emitting device. Contents of the invention [0004...
