Abstract

A light-emitting device includes a substrate, a light-emitting component, a wavelength conversion component, an adhesive and a reflective layer. The light-emitting component is disposed on the substrate. The wavelength conversion component includes a high-density phosphor layer and a lower-density phosphor layer. The adhesive is formed between the light-emitting device and the high-density phosphor layer. The reflective layer is formed above the substrate and covers a lateral surface of the light-emitting component, a lateral surface of the adhesive and a lateral surface of the wavelength conversion component.
