LIGHT-EMITTING SEMICONDUCTOR POTTING COMPOSITION AND LIGHT-EMITTING SEMICONDUCTOR DEVICE |
摘要 |
A potting composition comprising (A) an organopolysiloxane having a vinyl group at an end of its molecular chain, (B) an organohydrogenpolysiloxane, (C) a platinum group metal catalyst, and optionally, (D) an organosilicon compound having a silicon atom-bonded alkoxy group. The cured product of the composition has a refractive index of 1.41-1.56 at 25� C. and 589 nm (sodium D line). The composition is suited for the embedment and protection of light-emitting semiconductor members. A package in which a light-emitting semiconductor member is embedded and protected with the potting composition undergoes little discoloration and maintains a high emission efficiency in heating tests, thus offering a light-emitting semiconductor device featuring a long life and energy saving. |
