Fluorinated Resin Composition for LED Encapsulation

The patent applies composite materials by combining fluorinated polymer units (for UV resistance) with functional groups (carboxyl, hydroxyl, epoxy, isocyanate, or cyano groups) in a single encapsulating resin composition. This composite approach maintains resistance to short-wavelength light degradation while achieving adequate encapsulation performance alone, eliminating the need for additional encapsulating members.

The patent merges multiple functions (UV resistance, heat resistance, and encapsulation performance) into a single resin composition. By incorporating functional groups with specific thermal properties alongside fluorinated polymer units, the composition achieves high heat resistance without requiring additional encapsulating members, thereby maintaining production efficiency.

The patent changes the chemical composition parameters by using fluorinated polymer units as the base, which inherently provide resistance to short-wavelength light degradation. The functional groups are selected to ensure ease of manufacture and encapsulation, thus achieving both ease of manufacture and resistance to degradation through compositional parameter optimization.
