Abstract

A manufacturing method is provided. The manufacturing method includes the following steps. Firstly, a substrate and a light-emitting component are provided, wherein the light-emitting component is disposed on the substrate. Then, a wavelength conversion layer is provided, wherein the wavelength conversion layer includes a high-density phosphor layer and a low-density phosphor layer. Then, the high-density phosphor layer is adhered to the light-emitting component by an adhesive. Then, a reflective layer is formed above the substrate, wherein the reflective layer covers a lateral surface of the light-emitting component, a lateral surface of the adhesive and a lateral surface of the wavelength conversion layer.
