Fluorescent Lamp Environmental State Improvement
Albert Abbyasovich Ashryatov and Andrey Mikhailovich Kokinov
Abstract: The study is dedicated to the increase of fluorescent lamp environmental state. The existing methods of fluorescent lamp environmental state improvement, their advantages and disadvantages are analyzed. It was proposed to introduce mercury into a lamp in a bound state in the form of titanium mercuride placed in a capsule which is welded to one of the leg inputs without an exhaust tube and with a mounted electrode. The manufacturing process of environmentally improved fluorescent lamps was studied. The shortcomings of the current technological process were determined. The elimination of these shortcomings required the improvement of fluorescent lamp mercury formation (mercury vapor release from titanium mercuride in a sealed off lamp volume) on a test device. The feature of the scheme is the fluorescent lamp DC supply which is more than two times greater than the nominal current discharge and the electrode performing the cathode role operates in the mode of two cathode spots. Besides, the device to monitor the purity of fluorescent lamp filling after their sealing off on a pumping machine. The method of mercury vapor presence control in a sealed off fluorescent lamp is described. In order to improve the environmental state of fluorescent lamp production process the thermal decomposition of titanium mercuride in a capsule is proposed to perform after the production seasoning of finished fluorescent lamps, during which the manifestation of lamp latent defects takes place.
