GLASS COATING ON LEAD-THROUGH CONDUCTORS IN A LOW-PRESSURE SODIUM DISCHARGE LAMP

摘要

Low Pressure Sodium Lamp has a discharge vessel (1) to have second pinched seal (2), extends in discharge tube (1) by these conducting wire (4) electrodes (3). Electric conductor (4) respectively has the first glass coating (5), forms internal pinch-sealed (2) to discharge container (1) and adjacent first (5) of the second lime glass coating (6) and the outside (1) for extending to discharge container. The first new sodium resistant glass coating (5), it substantially lacks borate, for definition.
