Patent number: 8072139Abstract: Disclosed is a method for sealing a light-emitting device wherein formation of air bubbles in a light-emitting device module can be prevented by performing no gelation after fitting of a cover member. This method also enables to seal a light-emitting device by using a gel sealing material composed of a gel precursor which uses a solvent. Also disclosed is a light-emitting module formed by such a sealing method. In this method for sealing a light-emitting device, gelation of the gel precursor of a gel sealing material is performed before placing the precursor on the light-emitting device, and thus no gelation is necessary after fitting of a cover member. Consequently, a gel precursor having high viscosity that is difficult to be used in an injection method can be used in this method. Furthermore, a substance which requires use of a solvent can be used as a gel precursor of a gel sealing material.Type: GrantFiled: March 9, 2006Date of Patent: December 6, 2011Assignees: Sony Corporation, Sony Chemical & Information DeviceInventors: Kouki Hatsuda, Hiroshi Samukawa
