摘要	A method of making an LED light emitting device is disclosed. The method includes forming a multilayer encapsulant in contact with an LED by contacting the LED with a first encapsulant that is a silicone gel, silicone gum, silicone fluid, organosiloxane, polysiloxane, polyimide, polyphosphazene, sol-gel composition, or a first photopolymerizable composition, and then contacting the first encapsulant with a second photopolymerizable composition. Each photopolymerizable composition includes a silicon-containing resin and a metal-containing catalyst, the silicon-containing resin comprising silicon-bonded hydrogen and aliphatic unsaturation. Actinic radiation having a wavelength of 700 nm or less is applied to initiate hydrosilylation within the silicon-containing resins.
其他摘要	公开了一种制造LED发光器件的方法。该方法包括通过使LED与第一密封剂接触而形成与LED接触的多层密封剂，所述第一密封剂是硅凝胶，硅树脂胶，硅氧烷流体，有机硅氧烷，聚硅氧烷，聚酰亚胺，聚磷腈，溶胶 - 凝胶组合物或第一可光聚合组合物。然后，使第一密封剂与第二光可聚合组合物接触。每种可光聚合的组合物包括含硅树脂和含金属的催化剂，含硅树脂包含与硅键合的氢和脂族不饱和度。施加波长为700nm或更短的光化辐射以引发含硅树脂内的氢化硅烷化。
主权项	A method of making a light emitting device, the method comprising: providing a light emitting diode; and forming a multilayer encapsulant in contact with the light emitting diode, wherein forming the multilayer encapsulant comprises: contacting the light emitting diode with a first encapsulant comprising a silicone gel, silicone gum, silicone fluid, organosiloxane, polysiloxane, polyimide, polyphosphazene, or sol-gel composition; contacting the first encapsulant with a photopolymerizable composition comprising a silicon-containing resin and a metal-containing catalyst, the silicon- containing resin comprising silicon-bonded hydrogen and aliphatic unsaturation; and applying actinic radiation having a wavelength of 700 nm or less to initiate hydrosilylation within the silicon-containing resin thereby forming a second encapsulant.
