Abstract
A fabrication method for discharge lamps is disclosed, which comprises providing a glass tube of diameter between 2 and 20 mm, the glass tube having an inner wall coated with a fluorescent phosphor and having a through-passage with a first end and a second end, connecting a first dielectric electrode to the first end of the glass tube by applying an adhesive to a contacted portion of the glass tube and the first dielectric electrode, and sintering the contacted portion of the glass tube and the first dielectric electrode to securely connect the glass tube and the first dielectric electrode. Subsequently, processes of filling and sealing are conducted to complete the fabrication of the discharge lamps.
