Light-emitting device and manufacturing method thereof

A light-emitting device, comprises:

• a substrate;
• a light-emitting component coupled to the substrate;
• a wavelength conversion layer comprising a high-density phosphor layer and a low-density phosphor layer;
• an adhesive layer adhering the wavelength conversion layer directly to an upper surface of the light-emitting component and covering a portion of a lateral surface of the light-emitting component, wherein the high-density phosphor layer faces to the upper surface of the light-emitting component;
• a reflective layer formed above the substrate and covering the light-emitting component, the adhesive layer and the wavelength conversion layer to expose an upper surface of the wavelength conversion layer, wherein a curved surface of the reflective layer is inclined to the lateral surface of the light-emitting component and reflects a light emitted from the light-emitting component back into the high-density phosphor layer;
• and
• a dome-shaped lens layer formed on the substrate and encapsulating the light-emitting component, the wavelength conversion layer, the adhesive layer and the reflective layer.
