摘要

Disclosed is a resin composition for light-emitting device sealing, which contains a silsesquioxane resin containing two or more oxetanyl groups, an aliphatic hydrocarbon containing one or more epoxy groups, and a cationic polymerization initiator. Also disclosed is a lamp comprising a package having a cup-shaped sealing portion, an electrode exposed at the bottom of the sealing portion, and a light-emitting device arranged on the bottom of the sealing portion and electrically connected with the electrode. The light-emitting device is sealed with the resin composition for light-emitting device sealing which is filled into the sealing portion.
