Definitions

  • the invention relates to an adapter set for fluorescent lamps for conversion to smaller diameter fluorescent tubes with electronic ballast (electronic ballast), according to the preamble of patent claim 1.
  • the invention relates to lighting systems for T8 / T12 fluorescent lamps for conversion to modern and energy-saving T5 fluorescent tubes with electronic ballasts.
  • These fluorescent tubes are straight, double capped fluorescent tubes, which in each case in two associated versions on the fluorescent lamp carrier (wall or ceiling support) introduced (first inserted and subsequently screwed) can be.
  • T8 fluorescent tubes are to be understood as fluorescent tubes with a diameter of approx. 26 mm and a power-dependent length of approx. 590 mm, 1200 mm and 1500 mm.
  • T12 fluorescent tubes include fluorescent tubes with a diameter of approx. 38 mm and a power-dependent length of approx. 590
  • Under T5 fluorescent tubes fluorescent tubes with a diameter of approx. 16 mm and a performance-dependent length of approx. 288 mm, 549 mm, 849 mm, 1149 mm and 1449 mm are to be understood as meaning mm, 1200 mm and 1500 mm.
  • T8 and the T5 fluorescent tubes there is a difference in length of about 50 mm between the T8 and the T5 fluorescent tubes, which corresponds to the difference in length of the distance between the sockets of the fluorescent tube holders.
  • T8 / T12 fluorescent tubes which are usually operated with a conventional magnetic ballast
  • T5 fluorescent tubes can only be operated with an electronic ballast.
  • the recent adapter sets for fluorescent tubes are characterized in that the distance difference of the shorter T5 fluorescent tubes for T8 fluorescent tube holder is bridged by plugged on both sides of the T5 fluorescent tube adapter, with one or both adapter parts include the ECG.
  • standard-compliant operation e.g., compliance with electromagnetic compatibility
  • other electronic components e.g., a PFC filter
  • the 35Watt T5 fluorescent tube is not operated with its rated power, but in underload due to the electronic ballast limitation of current output, thus shortening the service life of the T5 tube considerably compared to standard-compliant operation.
  • the difference in length between the sockets of the fluorescent tube holders of the larger diameter fluorescent tube, e.g. T8, for the smaller diameter fluorescent tube, e.g. T5 is bridged by a single electronic ballast (ECG) as an adapter on one axial end side of the fluorescent tube and by an end cap adapter on the other axial end side of the fluorescent tube, wherein the electronic ballast comprises all the electronic components of a conventional electronic ballast.
  • ECG electronic ballast
  • the ECG and the end cap adapter each have on one axial end face pins with dimensions of larger diameter fluorescent tubes, eg T8, for inclusion in two fluorescent lamp sockets and on its other opposite axial end, contact sockets for receiving two contact pins the smaller diameter fluorescent tube, eg T5, have.
  • the advantage here is that thereby the already existing space between the sockets of the fluorescent tube holder of the larger diameter and longer fluorescent tube for smaller diameter and shorter fluorescent tube is bridged by the ECG and the end cap adapter and thus a conversion to a smaller diameter and in length shorter fluorescent tube, eg From T8 to T5 is easy, fast, secure and cost-effective.
  • the electronic components of the electronic ballast are located on at least two spatially separated from each other, but via flexible contact strips electrically interconnected part-boards.
  • the advantage here is that the electronic ballast is thus very compact and further electronic components in other places are unnecessary and thus the electrical connections can be kept short, and the associated assembly effort, which leads to a cheapening of the adapter set.
  • the electronic components of the electronic ballast are provided on 2, 3 or 4 spatially separated rigid part-boards or on a single flexible board, which can be angled to partial boards, said sub-boards each in the range of different longitudinal side walls of the Interior of the substantially cube, cuboid or general prismatic ECG housing are positioned.
  • said sub-boards each in the range of different longitudinal side walls of the Interior of the substantially cube, cuboid or general prismatic ECG housing are positioned.
  • at least one or even each of these sub-boards is in turn subdivided into further sub-boards, which are spatially separated from each other, but electrically connected to each other via flexible contact strips.
  • the ECG housing is preferably formed on the side facing the fluorescent lamp holder cylindrical, but on the side facing away from the fluorescent lamp holder cube or cuboid, in cross-section so square or rectangular and has 2 corners. This is a trouble-free insertion and insertion of the contact pins of the ECG and the End cap adapter in the associated versions of the fluorescent lamp holder possible.
  • the sub-boards, as well as their sub-part boards are preferably housed on a circuit board holder, which can be inserted together with the boards in the ECG housing and fixed there latched.
  • This PCB holder has at least two mounting fingers, which extend in the longitudinal direction of the fluorescent tube, and their free fingertips take the sub-board for the T8 contact pins and thus serve for the correct position insertion of another sub-board for the versions of the larger diameter fluorescent tube.
  • the ECG housing is formed closed on an axial end face and only the contact pins for receiving in the sockets of the fluorescent tube holder protrude through the ECG housing from the inside.
  • the ECG housing On the other axial end of the ECG housing, which is opposite to the fluorescent tube, the ECG housing is provided with an opening into which the PCB holder can be inserted axially with all the boards, so that the PCB holder in the ECG Housing is located.
  • a separate flange housing is provided, which is in or on this opening on or applied and then lock elastically resilient snap lugs on the flange and / or the ECG housing in associated recesses and thus a solid but in particular one-handed detachable connection between the flange housing and ECG housing forms.
  • a sealing gasket is inserted between flange housing and ECG housing.
  • this cladding serves on the one hand to give the impression that the larger diameter or longer fluorescent tube (eg T8) is present, and not the smaller diameter or shorter fluorescent tube (eg T5), whereby in a variety of fluorescent lamps a mix between already existing T8 and now replaced T5 fluorescent tubes can be present without it being recognized from the outside.
  • this cladding tube serves as a holding device for the electrical lines between the ECG and the contact pins of the end cap adapter.
  • At least one cable channel is produced in the axial extent of the cladding tube inside and / or outside the cladding during the production process of the cladding tube.
  • this at least one axial cable channel can also be subsequently attached after the production of the cladding tube itself to this or the cable can be inserted only in the cladding tube.
  • this at least one axial cable channel is arranged on the cladding tube such that, and thus the electrical lines accommodated therein, are located on the inside, which faces the fluorescent tube holder, i. at the side facing away from the light beam direction side.
  • the cladding tube is formed in particular from transparent or translucent, in particular extruded plastic, but may also consist of transparent or translucent glass, or a combination of these materials.
  • the inner diameter of the cladding tube advantageously corresponds approximately to the outer diameter of the fluorescent tube socket on which the contact pins are located.
  • the wall thickness of the cladding tube is approximately 1 mm, wherein for receiving a T5 fluorescent tube with a diameter of about 16 mm, the cladding tube has an inner diameter of about 23.6 mm and an outer diameter of about 25.4 mm, ie about the outside diameter of about 26 mm of a T8 fluorescent tube.
  • the entire design of housing and cladding is splash-proof, so that operation under damp conditions is possible.
  • the adapter set according to the invention according to the figures includes an ECG housing 1 with contact pins, which are designed for sockets for T8 fluorescent tubes and are soldered on a part-board 7d.
  • the PCB holder 2 together with the electronic ballast electronics 7 is then inserted into the interior of the ECG housing 1 and locked there.
  • the front free tips of the mounting fingers 2a are there to the sub-board 7d, on which the 2 pins 1 a for T8 sockets are, in the correct position and easily inserted into the interior of the ECG housing 1 and set there and the contact pins 1 a through the openings in the front side of the ECG housing 1. push through.
  • a flange 3 is axially slid onto the PCB holder 2 and locked by means of its snap lugs 3b with associated grooves in the ECG housing 1, wherein between the flange 3 and ECG housing 1, a sealing ring 4 is inserted.
  • the flange housing 3 also has plug-in contacts 3a, which enable an el. Contacting of the contact pins 6a of the opposite end cap adapter 6 via (not graphically) el. Wires in the cable channel 5a of the transparent or translucent cladding tube 5 to the electronic ballast by a simple plug connection.
  • the end cap adapter 6 On the pipe socket 3c of the flange 3, the one end of the cladding tube 5 is then pushed and there glued in particular. On the other end of the cladding tube 5, the end cap adapter 6 is pushed and also glued in particular, with the end cap adapter 6 has a part-board, which carries 2 pins 6a for T8 sockets, which from the free end face of the end caps Adapters 6 protrude and in the version of the fluorescent lamp can be inserted and screwed.
  • the T5 fluorescent tube is now accommodated with sockets 8a on both sides and 2 T5 contact pins each, the T5 contact pins being able to be inserted into assigned T5 sockets on the boards 7d of the electronic ballast and the flange housing 3.
  • the T5 fluorescent tube can be easily replaced.
  • all non-electrical and non-electronic components of the adapter set according to the invention are formed in plastic.
