Abstract: The present invention discloses a progressive-refractivity antireflection layer and a method for fabricating the same to eliminate light reflection occurring in an interface. The present invention is characterized in being fabricated via depositing a first material and a second material, and having a refractivity (neff) gradually varying with a thickness thereof and ranging between a refractivity (n1) of the first material and a refractivity (n2) of the second material. No matter at what thickness the refractivity (neff) of the antireflection layer is measured, the refractivity (neff) meets an effective medium theory expressed by an equation: neff={n12f+n22(1?f)}1/2, wherein f is a filling ratio of the first material of the antireflection layer.

Abstract: The present invention discloses a LED package structure and a module thereof. The LED package structure comprises a metallic chip-carrying lead frame, a metallic anode lead frame, a metallic cathode lead frame and a forming resin. At least one LED chip is stuck to the metallic chip-carrying lead frame. The metallic anode lead frame and metallic cathode lead frame are arranged beside the metallic chip-carrying lead frame. The forming resin includes a top member, a first sidewall, and a second sidewall. The top member is arranged on the metallic chip-carrying lead frame and has an opening to reveal the LED chip. A reflective wall is formed along the opening. The first sidewall is arranged between the metallic chip-carrying lead frame and the metallic anode lead frame to join them. The second sidewall is arranged between the metallic chip-carrying lead frame and the metallic cathode lead frame to join them.
