    Abstract: Embodiments relate to a light emitting device package having an improved luminous flux, and the light emitting device package includes a body including a cavity, a first lead frame and a second lead frame exposed on a bottom surface of the cavity and separate from each other by an electrode separating member, a first light emitting device disposed on the first lead frame, a second light emitting device disposed on the second lead frame, and a Zener diode disposed on the first lead frame or the second lead frame, and disposed more closely to the electrode separating member than to the first light emitting device and the second light emitting device. Here, the electrode separating member diagonally separate the first lead frame and the second lead frame along a width direction of the body.
