Title: (EN) Light emitting device package and lighting system using the same
Abstract: front page image
(EN)

A light emitting device package of the embodiment includes a body including cavities; first and second lead electrodes disposed in the cavity of the body; a light emitting device disposed in the cavities, electrically connected to at least one of the first and second lead electrodes and emitting a first main peak wavelength in the range of 410˜460 nm; and a first resin layer having first phosphor on the light emitting device, wherein the first phosphor of the first resin layer emits light of a second main peak wavelength in the range of 461 nm˜480 nm by exciting some light having the first main peak wavelength, and the first and second main peak wavelengths have the wavelength different from each other and contain the light having the same color.
