Definitions

  • the invention relates to a mounting unit for fluorescent lamps with a base on one side, with an essentially oval or square base provided with contact pins, and with an incandescent lamp base and a ballast connected thereto, comprising a coil former and a coil core.
  • Fluorescent lamps with a base on one side have recently been known, which provide a higher luminous efficacy than normal incandescent lamps with lower power consumption. Sockets are also known for these fluorescent lamps, but these are special sockets so that these fluorescent lamps cannot be used in place of conventional light bulbs in existing lamps. In addition, a choke coil is required for operation, which must be installed and connected separately.
  • the object of the present invention is to provide a mounting unit of the type mentioned at the outset, which makes it possible to use fluorescent lamps with a base on one side in luminaires which have conventional light bulb holders and which have the lowest possible structural height and a diameter such that they are not substantially larger than a bulb socket.
  • the incandescent lamp base receives an insert as a socket for the base of the fluorescent lamp and the ballast with a ring core concentrically surrounds the part of the base protruding from the incandescent lamp base up to approximately the glass of the fluorescent lamp and is connected to the insert.
  • the incandescent lamp base is used as a socket for the base of the fluorescent lamp, while the ballast with its ring choke surrounds the part of the base of the fluorescent lamp that protrudes from the bulb base in such a way that the lower part of the base of the fluorescent lamp with the thermally sensitive interference suppression capacitor or Starter is located in a cool area in the bulb socket and not in the area surrounded by the coil body and its toroid.
  • Such an assembly unit can be easily inserted or screwed into a conventional incandescent lamp holder and at the same time carries the ballast (choke) required for operating the fluorescent lamp and, if appropriate, also the starter therefor, which can also be arranged interchangeably.
  • the choke surrounds the section of the base from which the contact pins protrude and which is located adjacent to the glass tubes. Furthermore, it is located outside the bulb holder, is arranged concentrically to it and practically does not hinder the light emission, but rather leads to a light control.
  • the outer diameter of the choke corresponds essentially to that of the incandescent lamp holders, so that there is also protection against contact, which is important because of the high ignition voltage when screwing in the assembly unit with a fluorescent lamp already inserted.
  • the incandescent lamp base which receives the base of the fluorescent lamp, extends almost to the ceramic insulator of the incandescent lamp base, so that the base of the fluorescent lamp is predominantly taken up by the incandescent lamp base and thus a full use of space is achieved in addition to the cool arrangement of the thermally sensitive parts.
  • the toroid has two coils arranged on opposite sides. In the case of an oval base, the coils can be arranged in the longitudinal region of the oval base. With a square base, a toroidal coil on the toroidal core can be useful.
  • the insert is preferably connected to a jacket that receives the ballast.
  • the ballast is provided with the jacket by casting, for which purpose, for example, a thermoset is used which is cast with low pressure.
  • the insert can be connected to the jacket via a snap connection.
  • the casing with the ballast can also be arranged such that it can be adjusted in height in relation to the insert.
  • the insert can be provided with a toothing into which a latching cam of the jacket engages.
  • the jacket can have spring-loaded extensions which snap into place behind retaining cams of the base.
  • the insert can also have spring-preloaded tongues which extend transversely to the longitudinal axis of the bulb base and engage behind the base's retaining cams and clamp the base.
  • the tongues can also be isolated metal springs which are supported in use.
  • the extensions or tongues can also be spring-biased by spring contacts for contacting the contact pins.
  • the insert accommodates contact springs for contacting the contact pins in an intermediate space which is closed except for insertion openings for the contact pins and bushing openings for lines or contact plates.
  • the space to the outside in the direction of the fluorescent lamp can be covered by a base, which is optionally formed in one piece with the jacket.
  • the contact springs can be leaf springs, which can also be angular.
  • the toroidal core can consist of sheets with a section in the shape of a sector of a circle and an arcuate section, two gaps being provided in each case.
  • the toroidal core can be at least partially attached to a coil former be arranged, wherein the arcuate sections can each be arranged in a coil body, on which the coil is wound and two units thus formed are combined to form a choke coil, in particular via a toothing, the coil bodies fixing the gaps.
  • the toroid consists of sheets laminated in the direction of the longitudinal axis of the incandescent lamp holder in the form of a parallelogram and can also be designed as a winding core, in particular a band for winding can be used which is provided with slots in such a way that they are arranged one above the other during winding in order to to form the air gap.
  • the slots arranged perpendicular to the longitudinal axis of the band are delimited on the edge by narrow webs.
  • the toroidal core as well as the coil and the jacket at the end facing away from the bulb base can be designed to widen conically outwards, wherein the conical widening of the jacket can be stepped all around and optionally mirrored.
  • a switchable bimetallic fuse is provided, which can be arranged in the space between the insert and the bulb socket, the bimetallic fuse can be connected to a switch arranged on the insert, which can be actuated by inserting and removing the fluorescent lamp.
  • the bimetallic fuse can be switched on manually or by inserting the fluorescent lamp.
  • a space can be provided between the insert and the bulb socket for receiving electronic components, a preheating transformer, a capacitor or electronic components of a twilight switch.
  • the insert can have a plug connection for a starter for the fluorescent lamp to be inserted therein.
  • the insert can accommodate a coupling piece, which is designed as a plug corresponding to the base and carries two sockets for fluorescent lamps in tandem and optionally a starter for this.
  • the coupling piece can have a mounting plate which faces the two sockets towards one another and carries them offset with respect to their central axis, so that the fluorescent lamps can be inserted parallel to one another in a plane perpendicular to the longitudinal axis of the mounting unit.
  • the coupling piece can also carry a mounting plate with arms bent backwards in the direction of the longitudinal axis of the mounting unit, to which the two sockets are fastened, so that the fluorescent lamps can be inserted parallel to one another and to the longitudinal axis of the mounting unit.
  • the ballast can instead of a coil body with coil core made of a printed circuit, which is circular on the outside and oval on the inside with an oval base, which comprises a DC converter with push-pull circuit and pulse generator and a current limiting capacitor.
  • the assembly unit shown in FIGS. 1 to 4 comprises an incandescent lamp base 1 with a base contact 2, which is fastened by means of an insulator 3 in an Edison thread 4, for example E 27 or E 40, and from which a line 5 leads away.
  • a bayonet base can also be used.
  • the Edison thread 4 also receives an insert 6 made of plastic.
  • the insert 6 serves to receive the lamp base 7 of a linear fluorescent lamp 8 (for example Phillips PL lamp) with a base on one side, which in the illustrated embodiment has an oval two-pin base 7 (G 23, G 32 or the like) in which the starter for the Fluorescent lamp 8, which has two glass tubes 9 arranged next to one another and connected to one another, is accommodated.
  • the lamp base 7 is provided on two opposite sides in each case with a contact pin 10, each below a glass tube 9, which extend downward, while holding cams 11 are provided on the other opposite sides of the lamp base.
