#Encore energy saving ballast series#
An energy-saving lamp, comprising a lamp base comprised of an outer contact part and a central contact, and a base insulator of insulating material arranged between the outer contact part and the central contact, a gas discharge lamp comprised of at least one glass tube with connecting wires melted therein, a lamp insert comprised of an upper part and a lower part, wherein the upper part covers an end of the glass tube and the connecting wires, and wherein the lower part provides a mechanical connection with the lamp base, an electronic ballast for generating an alternating supply voltage required for the operation of the gas discharge lamp, wherein the electronic ballast comprises a printed board on which electric and electronic components are mounted and connected, wherein the electric and electronic components are a mains suppressing reactor, a lamp series reactor, an oscillating circuit transformer with three metallically separated coils, two switching transistors, and connecting wires to the gas discharge lamp, wherein the printed board extends upright in the lamp base, the switching transistors having cooling bodies mounted so as to be insulated relative to the lamp base, the lamp series reactor being comprised of an open coil body supporting a coil, and a U-shaped core covering the coil body with a sufficiently large air gap, wherein the coil body is seated in a cutout on an edge of the printed board, the oscillating circuit transformer being comprised of a flat rectangular annular core and being seated in a cutout in the printed board, the three coils being formed as printed conductors, wherein one half of the coils are positioned on the printed board, and the other half of the coils are positioned on an additional board, the additional board being inserted upside-down through the annular core and corresponding partial coils being soldered to one another, and an inner lid being placed on the lamp base, wherein the inner lid comprises locking grooves for securing the printed board laterally, and openings for the connecting wires to the gas discharge lamp.Ģ.
