Dielectric barrier discharge lamp and fabrication method thereof

摘要

A dielectric barrier discharge lamp includes a lamp tube, a discharge gas, a support member, a first electrode, and a second electrode. The lamp tube has a first and a second sealed end. The discharge gas is filled in the lamp tube. The support member is disposed at the first sealed end and extended toward the inside of the lamp tube. The support member has an accommodating space with its opening facing the inside of the lamp tube. The first electrode is disposed in the lamp tube. A first terminal of the first electrode passes through the opening of the accommodating space. A gap exists between an end of the first terminal of the first electrode and a closed end of the accommodating space. A second terminal of the first electrode penetrates and is closely fitted with the second sealed end. The second electrode is disposed outside the lamp tube.

主权项

1. A dielectric barrier discharge lamp, comprising:
a lamp tube, having a first sealed end and a second sealed end; a discharge gas, filled in the lamp tube; a support member, disposed at the first sealed end, and extended from the first sealed end toward an inside of the lamp tube, wherein the support member has an accommodating space, and an opening of the accommodating space faces the inside of the lamp tube; a first electrode, disposed from inside to outside of the lamp tube, wherein a part of the first electrode inside the lamp tube is exposed to the discharge gas and a first terminal of the first electrode passes through the opening of the accommodating space so that another part of the first electrode inside the lamp tube is in the accommodating space, and a gap exists between an end of the first terminal of the first electrode and a closed end of the accommodating space, while a second terminal of the first electrode penetrates the second sealed end to outside of the lamp tube and is directly contact and closely fitted with the second sealed end; and a second electrode, disposed outside the lamp tube.
