METHOD OF SEALING LED DEVICE, AND LED DEVICE

摘要

A sealing method of an LED apparatus and the LED apparatus are provided to prevent the silver plating from being discolored by protecting the silver-plated reflector for a long time. The primer composition containing the acryl resin 1 to 50 mass% in which the content of the silicon atom of 0.1 to 5 mass% is contained is coated on the surface of the plating part of the substrate plated with silver. The primer composition has the acryl resin coated the silvering part as the main component. The hardening material of heating and hardening type silicone composition seals the silver-plated surface and the LED chip. The heating and hardening type silicone composition use the transition metal oxide as the catalyst.
