Abstract

Disclosed herein is a light emitting device package and a light emitting device package module. The light emitting device package includes: a base including a cavity; a first light emitting device disposed in the cavity, the first light emitting device including a first light emitting element configured to produce light having a first peak wavelength and a first fluorescent layer covering a top and side surfaces of the first light emitting element; and a second light emitting device disposed in the cavity, the second light emitting device including a second light emitting element configured to produce light having a second peak wavelength and a second fluorescent layer covering a top and side surfaces of the second light emitting element, wherein the first fluorescent layer is configured to convert the light having the first peak wavelength of the first light emitting element to light having a third peak wavelength, and the second fluorescent layer is configured to convert the light having the second peak wavelength of the second light emitting element to light having a fourth peak wavelength.
