摘要:
A lighting device disclosed in an embodiment of the invention includes a substrate; a light emitting device disposed on the substrate; a resin layer sealing the light emitting device on the substrate; and a diffusion layer or a reflective substrate disposed on the resin layer, wherein the resin layer includes an oligomer, a monomer, and an additive, wherein the monomer includes IBOA (Iso-bornyl Acrylate), two or more dilution monomers and glycidyl methacrylate (GMA), the additive includes a photoinitiator and an amine-based light stabilizer, and in the oligomer and the monomer, the content of glycidyl methacrylate is 10 to 15%, and the resin layer may be a curable transparent resin cured by ultraviolet light.
