Abstract
It is an object of the present invention to assuredly prevent occurrence of minute cracks in a seal portion of a lamp for improvement of the pressure resistance and service life of the lamp. To achieve the object, there is provided a seal structure of a lamp including: (a) a lamp envelope having a light emitting tube and a seal portion; (b) a metal foil embedded in the seal portion of the lamp envelope; (c) a light emitting element attached to one of opposite ends of the metal foil and disposed in the light emitting tube; and (d) an outer lead rod attached to the other end of the metal foil and led out of the seal portion, the seal structure comprising a separable layer interposed between the seal portion and a portion of the light emitting element embedded in the seal portion.

A mount for use in a lamp having a light emitting tube portion and seal portions, the mount comprising:
- a metal foil to be embedded in the seal portion of the lamp;
- a light emitting element attached to one of the opposite ends of the metal foil and adapted to be introduced in the light emitting tube portion;
- and
- an outer lead rod attached to the other end of the metal foil and adapted to be led out of the seal portion,
- wherein a separable layer configured to separate from a surface portion of the light emitting element is provided on the surface of the portion of the light emitting element to be embedded in the seal portion.
A mount for use in a lamp having a light emitting tube portion and seal portions, the mount comprising:
- a metal foil embedded in a glass bead to be embedded in the seal portion of the lamp;
- a light emitting element attached to one of opposite ends of the metal foil and adapted to be introduced in the light emitting tube;
- and
- an outer lead rod attached to the other end of the metal foil and adapted to be led out of the seal portion,
- wherein a separable layer configured to separate from a surface portion of the light emitting element is provided on the surface of the portion of the light emitting element to be embedded in the seal portion.
