Abstract
An LED package structure includes a conductive frame assembly, a reflective housing, an UV LED chip disposed on the conductive frame assembly, and a die-attach adhesive for bonding the UV LED chip to the conductive frame assembly. The reflective housing includes Silicone Molding Compound (SMC) and filler mixed in the SMC. The energy gap of the filler is greater than or equal to 4 eV. The energy gap of the filler thereof can be chosen by the following formulas. When the refractive index difference between the filler and the SMC is less than or equal to 0.2, the energy gap of the filler is satisfied the following formula. E≥1240 (nm·eV)/(λ−150(nm)). When the refractive index difference between the filler and the SMC is greater than 0.2, the energy gap of the filler is satisfied the following formula. E≥1240(nm·eV)/(λ−50(nm)).
