Definitions

  • the invention relates to a ballast for fluorescent lamps in construction to coat ebautem g, layered in the longitudinal axis of the magnetic circuit core package having a height half as large as the width thereof and inserted into the core window coil of the choke coil.
  • Such a choke coil has become known from DE-OS 19 17 938.
  • There smaller D rossel height and optimal throttle cross-section is aimed at maximum utilization of the iron flat construction. In addition to the exact height-width ratio of the core package, this should be achieved in particular by arranging the centers of the core windows in the longitudinal axis of the rectangle.
  • the accessories such as inductor, capacitors and starters, are individually mounted in the luminaires for fluorescent lamps with a tube diameter of 26 mm and a lamp output of up to 30 watts.
  • the cross section of the ballast has a width approximately equal to the tube diameter of the fluorescent lamp and a height of at least 23 to 24 mm, so that the cross-sectional shape of the ballast is almost square.
  • the invention has for its object to a ballast of the type described for modern fluorescent lamps of the extended power levels 36 watts and 59 watts with a tube diameter of 26 mm. create, which has the smallest possible height and results in a minimal cross section of the entire lamp.
  • the width of the core package of the choke coil is approximately equal to the diameter of the fluorescent lamp
  • the width of the middle leg is equal to a quarter of the width of the core package and the width of the side legs and the height of the yoke parts is equal to one eighth of the width of the core package
  • the insulating part is are coil extends on at least one of the front sides of the choke coil in the longitudinal direction ist'und that on the extension of the insulating part the components for the lamp, glow starter, capacitor for the glow starter, Tem p eratur Klinsator within a cross section approximately equal to the cross section of the core stack of the choke coil mounted .
  • This design of the core package results in approximately square core windows, with the specific material stress surprisingly not being increased by the magnetic induction in the magnetic circuit and the current density in the conductor of the coil without additional material expenditure for the magnetic circuit and the coil.
  • the winding cross section of the coil is approximately halved and the layer length of the core package is approximately doubled, so that no additional expenditure on winding material and core material is required to achieve the same properties as before.
  • the fluorescent lamp can be attached directly above the choke coil.
  • ballast which can be rationally produced in series production and which can be easily installed in the luminaire, the work steps previously carried out separately in the luminaire when mounting the accessories already being carried out rationally during the production of the integrated ballast as a unit in series production can be.
  • the insulating parts on both end faces of the choke coil are advantageously extended in the longitudinal direction and the accessories for the lamp are attached to the extensions on both end faces of the choke coil.
  • the connecting lines required for starter operation are expediently laid in the core windows of the inductor.
  • the core package can have a longitudinal recess in the magnetically neutral zone in which the connecting lines required for starter operation are laid.
  • the extensions of the insulating parts are expediently box-shaped with a lid.
  • the extensions of the insulating parts together with the choke coil can expediently be pushed into the carrier profile of the fluorescent lamp p e and fastened there.
  • FIG. 1 and 2 show a ballast according to the invention without insulating parts on the end parts with a core package 1 in a longitudinally layered jacket construction, associated coil 2 and indicated fluorescent lamp 3.
  • the magnetic circuit of the core package 1 can be constructed from ET sheets, EE sheets, etc.
  • the width of the core package 1 is B, the height of the core package 1 H and the length of the core package 1 L.
  • the diameter of the fluorescent lamp 3 is D.
  • the width B of the core package 1 is equal to the diameter D of the fluorescent lamp arranged directly above it.
  • the height H of the core package 1 is half its width B.
  • the width of the middle leg of the core package b is equal to a quarter of the width of the core package 1 B, the width of the side legs of the core package 1 and the height of the yoke parts of the core package 1 is b / 2, i.e. half the width b of the middle leg. This results in square core windows of height h equal to width b.
  • a flat, elongated choke coil is obtained while maintaining the specific material stress, such as the magnetic induction in the magnetic circuit and the current density in the conductor of the coil 2, while the material expenditure for the core package 1 and the coil 2 is not greater than in previously known ones approximately square cross-sectional shapes of the core package 1.
  • the winding cross-section for the coil 2 is halved and the layer length of the core package 1 is doubled, so that the same is achieved to achieve The properties of the choke coil do not result in additional expenditure on winding material and core material.
  • FIGS. 3 to 7 show an exemplary embodiment of a ballast according to the invention, in which the insulating parts on both sides of the core package 1 of the choke coil are designed with box-shaped extensions 4 and covers 5 in the longitudinal direction of the choke coil.
  • the cover 5 has upstanding projections 6 which are adapted to the cross section of the support profile of the fluorescent lamp for insertion into it.
  • the cross section of the extensions 4 together with the cover 5 is slightly larger than that of the core package 1.
  • glow starter 7 and the capacitor 8 for the glow starter 7 are attached within their cross section.
  • the radio interference suppression capacitor 9 and the temperature fuse 10 are likewise attached to the other extension 4 within their cross section.
  • a longitudinal recess 11 is provided in the magnetically neutral zone, in which the connecting lines 12 required for starter operation are laid.
  • the integrated ballast needs after its manufacture only be attached to the carrier profile of the fluorescent lamp, whereupon the two line connections to the socket only have to be made on each end face of the lamp profile.
