Abstract
A fluorescent lamp includes a glass envelope having a sealed end portion, an insulator disk positioned on the envelope end portion, and a collar of shrink wrap material disposed around the envelope end portion and the insulator disk, the shrink wrap material being shrunken and compressing against the envelope end portion and the insulator disk, to fix the insulator disk on the envelope end portion.
Claims19
A fluorescent lamp comprising:
- a glass envelope having a sealed end portion;
- an insulator disk mounted on the envelope end portion;
- and
- a collar of shrink wrap material disposed around the envelope end portion and said insulator disk, the shrink wrap material being shrunken and compressing against the envelope end portion and said insulator disk, to fix said insulator disk on the envelope end portion.
A method for attaching an insulator disk to an end of a fluorescent lamp glass envelope, the method comprising the steps of:
- providing an annular end portion on an external glass wall portion of the glass envelope;
- mounting the insulator disk on the end portion of the envelope;
- applying a collar of shrink wrap material to the envelope end portion and the insulator disk;
- and
- shrinking the collar to compress against the envelope end portion and the insulator disk, to fix the insulator disk on the envelope end portion.
A fluorescent lamp comprising:
- a glass envelope having a sealed end portion,
- an insulator disk mounted on the envelope end portion and engaged with the envelope end portion;
- a collar of wrap material disposed around the envelope end portion and the insulator disk, and
- an adhesive disposed on an interior surface of said collar and contiguous with the glass envelope end portion and said insulator disk, to fix said insulator disk on the envelope end portion.
A method for attaching an insulator disk to an end of a fluorescent lamp glass envelope, the method comprising the steps of:
- providing an annular end portion on a wall of the glass envelope;
- mounting an insulator disk on the end portion of the envelope;
- and
- applying a collar of wrap material to the envelope end portion and the insulator disk, the wrap material having a layer of adhesive on an interior surface thereof to fix the insulator disk on the envelope end portion.
