The invention relates to a light emitting diode device having a light extracting rough structure. The device includes a leadframe, one or more light emitting diode chips provided on and electrically connected to the leadframe, and a lens configured to encapsulate the one or more light emitting diode chips, the lens having a surface including a micro-roughness structure. The micro-roughness structure of the lens has a roughness between 0.1 μm and 50 μm. The invention also relates to a method of manufacturing a light emitting diode device having a light extracting rough structure.
