Abstract
The present invention is directed to a dielectric barrier discharge lamp capable of recovering reduced radiation efficiency by easily, quickly cleaning dust or discoloring of a discharge tube or replacing any defective discharge tube. For this end, an internal electrode in a form of electrically conductive rod is inserted into a center hole of a dual discharge tube having discharge gas filled in an internal space . Holders and are removably mounted on both ends of the internal electrode using mounting screws . A protection tube is mounted onto the holders by way of sealing members pressure blocks and pressure rings in such a manner to cover an external electrode of the discharge tube Cooling water or the like may be permitted to flow in a continuous space formed between the internal electrode and the discharge tube and the holders
