Evaluation of the Efficiency of an Argon Coaxial Lamp
Résumé
This paper presents the experiments achieved in the DPHE laboratory in collaboration with the LPPMCA laboratory for the development of mercury-free fluorescent lamp concurrent light. Mercury emits UVs photons at a wavelength of 254 nm, but due to its high toxicity, mercury (Hg) has been classified by the World Health Organization (WHO) as one of the top ten chemicals posing a major risk to public health [1]. It is thus necessary to develop new free mercury UV light sources for decontamination of wastewater and water sterilization processing. Dielectric barrier discharge (DBD) interest to “lighting designers” who, for environmental considerations (energy saving and mercury disposal), would like to replace the mercury of discharge lamps [2, 3]. The excitation of rare gases by DBD provides a beneficial arrangement for the generation of radiation in the VUV, UV and IR range. The scope of this study concerns the domain of low-pressure, low-power fluorescent lamps. We focused on the electrical characteristic, optical emission spectroscopy of plasma produced in a dielectric barrier discharge by a high pulse generator (3 kV–100 kHz). The first purpose of these measurements is to analyze the operating range of the plasma lamp and optimize it in order to improve efficiencies.
