Abstract: The present invention relates to an ultraviolet lamp comprising a glass shell and an electrode fixed on one or more ends of the lamp, where each electrode is a coiled wire with a hollow conical shape. The hollowed conical structure of the electrode reduces the thermal capacity of the electrode as compared with other types of electrodes of the same mass, makes the lamp start quicker, and decreases the emission loss of the electrode when the glow discharge is transformed to an arc discharge. The lamp of the present invention has a wide electrode surface area, such that the loads on each point of the emissive surface are equally distributed, thus decreasing the electron scattering and dispersion, and allowing the lamp to resist the impact from positive ions. Due to the shape and structure of the electrode, the lamp of the present invention has increased efficiency and emitting ability, and allows for a longer lasting lamp.
