Double-tube excimer lamp

Abstract

The invention relates to the technical field of photoelectric reactors. The invention discloses a double-tube excimer lamp. The lamp comprises a base, a left luminous tube is arranged on the left sideof the base. A left outer tube is arranged on the outer side of the left luminous tube; a left metal coating is arranged on the right side of the inner wall of the left outer pipe; a right luminous tube is arranged on the right side of the base; a right outer tube is arranged on the outer side of the right luminous tube; a right metal coating is arranged on the left side of the inner wall of theright outer pipe; inner cavities are formed in the middle of the left outer pipe and the middle of the right outer pipe respectively. The middle parts of the inner cavities are respectively filled with luminous gas; the left metal coating and the right metal coating are semicircular; an external electrode is abandoned, an electric field is formed after the left metal coating and the right metal coating are directly discharged, the left metal coating and the right metal coating are arranged on the inner wall of the left outer pipe and the inner wall of the right outer pipe respectively, the left outer pipe and the right outer pipe do not make contact with corrosive gas possibly existing outside the pipes after being sealed, and the service life is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of photoelectric reactors, in particular to a double-tube excimer lamp. Background technique [0002] Existing excimer lamps are equipped with external electrodes outside the lamp tube. The high-frequency and high-voltage alternating electric field generated by the electrodes excites the luminescent gas in the container to emit excimer ultraviolet light, and the light-transmitting gaps of the external electrodes are very easy to adhere to solid particles. and solid-liquid high molecular polymers, thereby affecting the luminescence and discharge performance of excimer discharge lamps, and even bringing safety hazards. In addition, the external electrodes are exposed and used under corrosive gas conditions, which may cause the electrodes to be corroded, which shortens the service life of the excimer lamp. Contents of the invention [0003] In order to make up for the above shortcomings, the present inventio...
