    • To provide a light-emitting device having an airtight container sealed at a lower temperature by means of a sealing material not containing a harmful component such as lead, which is free from heat deterioration of a phosphor, particularly a blue-emitting phosphor. A light-emitting device having an airtight container sealed by means of a sealing composition comprising a curable methylphenyl silicone resin and a refractory filler, wherein the amount of the refractory filler based on the sum of the methylphenyl silicone resin and the refractory filler in the sealing composition, is from 10 to 80 mass %, and the methylphenyl silicone resin has a molar ratio of phenyl groups to methyl groups (i.e. mols of phenyl groups/mols of methyl groups) of from 0.1 to 1.2.
    • 为了提供一种具有密封容器的发光装置,该气密容器借助于不含有诸如铅的有害成分的密封材料而密封,该密封材料不会发生荧光体,特别是蓝色发光荧光体的热劣化。 一种具有通过密封组合物密封的气密容器的发光装置,所述密封组合物包含可固化的甲基苯基硅树脂和耐火填料,其中所述耐火填料的量在所述密封中基于所述甲基苯基硅氧烷树脂和所述耐火填料的总和 组成为10〜80质量%,甲基苯基有机硅树脂的苯基与甲基的摩尔比(即苯基/甲基的摩尔数)为0.1〜1.2。
