Patent ID: 7872417

Claim:
A glass-sealed light emitting element, comprising: a light emitting element including a terminal-side surface having electrical terminals on the terminal side surface, and a backside surface opposed to the terminal side surface and configured to emit light from the backside surface; and a glass member sealing the light emitting element, the glass member including upper and lower regions defined by a principal axis extending along a longest horizontal direction with respect to the terminal-side surface of the light emitting element, the upper region formed by a continuous curved surface, and the lower region formed by the continuous curved surface of the upper region extending into at least a portion of the lower region, wherein the backside surface is at least partially sealed by the glass member and the terminal-side surface is at least partially exposed from the glass member, wherein: the principal axis extending in the horizontal direction with respect to the terminal side surface of the light emitting element has a diameter A, the glass member further comprising a principal axis extending along a longest vertical direction with respect to the terminal-side surface of the light emitting element and having a diameter B, and a portion of the lower-region, other than said continuous curved surface extending into the lower region, and having a diameter C, and the diameters A, B and C satisfy the expression A>B>C.
