发明名称 LIGHT EMITTING DEVICE HAVING REMOTELY LOCATED LIGHT SCATTERING MATERIAL
摘要 A light emitting device with a remotely located light scattering material which improves color mixing property is provided. The light emitting device includes a substrate defining a cavity; one or more light emitting elements bonded to the substrate and positioned in the cavity; at least one first layer covering the one or more light emitting elements, at least part of the at least one first layer within the cavity, wherein the at least one first layer has a refractive index less than the refractive index of the one or more light emitting elements; and at least one second layer including light scattering material disposed on the at least one first layer, wherein the refractive index of the first layer is less than or equal to the refractive index of the second layer.
