Abstract
The present invention provides a ceramic-glass composite electrode and a fluorescent lamp having the same. The ceramic-glass composite electrode according to the present invention is a ceramic-glass composite, which is disposed at the ends of a glass tube of the fluorescent lamp. A stopper is disposed at the end of the glass tube for pushing against the ceramic-glass composite electrode and limiting the position of the ceramic-glass composite electrode slipped on the glass tube. Thereby, flowing of adhesives into the glass tube is avoided when the adhesives are used for gluing the glass tube and the ceramic-glass composite electrode, and hence extending the lifetime of the fluorescent lamp.
Claims10
A fluorescent lamp having ceramic-glass composite electrodes, comprising:
- a glass tube;
- at least a stopper, disposed at at least an end of said glass tube;
- and
- a plurality of ceramic-glass composite electrodes, disposed at both ends of said glass tube, respectively, pushing against said stopper of said glass tube, and being a ceramic-glass composite.
A ceramic-glass composite electrode, comprising an electrode body, disposed at an end of a glass tube of a fluorescent lamp, being a cylinder and a ceramic-glass composite, and said cylinder having only one inner radius.
