摘要： Disclosed is a light-emitting diode package (100) including; a body (110) having a cavity (112) formed therein, a light source (130) mounted in the cavity, a resin layer (120) which fills the cavity and is transmissive, and at least one optical sheet (140) provided on the resin layer, wherein the optical sheet includes a first layer (142), and a second layer (144) which is provided on the first layer and has a plurality of linear prisms (145), wherein the first layer has a first refractive index and the resin layer has a second refractive index, and wherein the first refractive index is equal to or greater than the second refractive index. Accordingly, the light-emitting diode package may have improved luminous efficacy, enable uniform distribution of emitted light, and prevent degradation of a phosphor.
