High-pressure gas discharge lamp comprising a quartz glass wall enclosing a discharge space, sealed lamp, a metal foil embedded in the inner wall surface, and is coated with a quartz glass around the rod is connected to the coating and the metal foil adjacent to at least pick. Coating on the lever has strong adhesion. It is with the rod / coating interface boundaries contain additives. Another alternative approach is to add to the rod rhenium surface of the rod and its coating with interlocking structure. Since the completion of the sealing, the quartz glass and the rod has a strong adhesiveness and their very different coefficients of expansion between the coating and wall will be lost from the wall surface of the mechanical contacts.
HPS electronic ballast, He was excited by the half-bridge series resonant switching power supply circuit. High voltage pulse source is from the starter circuit itself, the transformer...
