Abstract
A light emitting diode package structure includes a substrate, a light emitting unit, a wavelength conversion layer, and a reflective structure. The light emitting unit and the reflective structure are disposed on a mounting surface of the substrate. The wavelength conversion layer is disposed on the light emitting unit. The wavelength conversion layer has a light input surface, a top light output surface opposite to the light input surface, and a side light output surface connecting the light input surface and the top light output surface. The reflective structure surrounds the light emitting unit and the wavelength conversion layer. The reflective structure has a top reflecting surface located on a top of the reflective structure, and a height position of the top reflecting surface is higher than a height position of the light input surface and lower than a height position of the top light output surface.
