Definitions

  • the invention relates to a lighting device according to the preamble of claim 1.
  • Discharge lamps have the advantage of a significantly higher luminous efficacy or economy than incandescent lamps.
  • a ballast and an ignition device are required, of which the ignition device provides the ignition voltage required for starting the gas discharge, while the ballast limits the lamp current after the discharge lamp has been ignited while it is in operation.
  • the ignition voltage must overcome the resistance in the discharge lamp and is proportional to the prevailing gas pressure. It can be up to 50 kv, but only needs to be present for a short time as a high-voltage pulse. After the discharge lamp has been ignited, the resistance inside the discharge lamp decreases and the previously very low lamp current can rise to impermissibly high values due to the negative resistance characteristic of the ionized gas. A ballast with a positive current-voltage characteristic is therefore required to limit the current. Ballasts can be designed as choke ballasts or as electronic ballasts, with choke ballasts a robust construction, high operational reliability and easy handling can be achieved. However, they require a relatively large amount of installation space, cannot compensate for the lamp tolerances and changes in the mains voltage, and are relatively difficult.
  • Electronic ballasts compensate for mains voltage and frequency fluctuations over a certain range, but are less robust and also require installation space, corresponding cooling devices and cause additional weight.
  • Ballast and igniter are usually accommodated in the housing of the lighting device, i.e. in the vicinity of the discharge lamp, since with a long line length from the ballast and igniter to the discharge lamp there are excessive losses or an excessive voltage drop, so that no reliable operation of the Discharge lamp is guaranteed.
  • the lighting device becomes very large and bulky.
  • Another disadvantage of the known lighting devices is that a separate ballast or ignition device is required for each discharge lamp, which leads to considerable costs when using a plurality of discharge lamps.
  • the object of the present invention is to provide lighting devices of the type mentioned at the outset which are versatile and can also be used in locations which are difficult to access and are spatially limited, are easy to handle and can be produced and operated economically even when several discharge lamps are in operation.
  • the operation of the lighting device in optionally three different configurations of a discharge lamp with a ballast and ignition device expands the area of application and the manageability of such lighting devices and enables the operation of different and also several discharge lamps simultaneously on one ballast and ignition device and thus cost-effective manufacture and cost-effective operation of the lighting devices.
  • discharge lamps are mechanically and electrically detachably connected to the ballast and igniter, different and also several discharge lamps can be operated simultaneously with one ballast and igniter.
  • the mechanical and electrical coupling of the discharge lamp to an external ignition device which is connected via a connecting cable to the current limiting circuit of a ballast and basic ignition device by bridging the ignition circuit of this device, creates a discharge lamp with small dimensions, which can also be used in places that are difficult to access .
  • the discharge lamp Since the discharge lamp is operated separately from the ballast and basic igniter, the discharge lamp can be started independently of the relatively large and heavy ballast and is therefore light in weight and can be used advantageously, particularly in confined spaces.
  • the short distance and the associated short line paths between the discharge lamp and the external ignition device minimize the transmission and voltage losses, so that safe operation of the discharge lamp is ensured.
  • the discharge lamp when the discharge lamp is operated with an external igniter, a direct connection is made to the ballast bypassing the basic igniter by bypassing the current limiting circuit of the basic igniter. This can be done, for example, by means of a corresponding electrical or electronic circuit arrangement, a switch or via a contact assignment of the adapter.
  • the external igniter can be attached directly to the discharge lamp or to the housing of the discharge lamp without further intermediate pieces.
  • connection between the discharge lamp and the housing of the ballast and basic ignition device is realized via an adapter, as a result of which a defined interface that can be used for multiple units is produced between the ballast and basic ignition device and the discharge lamp.
  • the adapter can be integrated as a separate component or in one of the modules to be connected.
  • a plurality of adapter connections are provided on the igniter so that a plurality of discharge lamps can be started with one igniter.
  • electronic ballasts it is possible to regulate the lamp current of a plurality of discharge lamps using a single ballast.
  • the external ignitor has an adapter connection which is advantageously designed to be compatible with the adapter connection of the ballast and ignition igniter.
  • the discharge lamp can be connected to both the ballast and advises as well as be operated on the external ignitor without structural changes or intermediate pieces are required.
  • the connecting cable has a plug that can be connected to several sockets of the external igniter.
  • an advantageous embodiment of the solution according to the invention is characterized in that the plug sockets of the external ignition device have different orientations or orientations.
  • an orientation in the direction of the light direction of the lamp and a direction perpendicular to the light direction of the lamp is appropriate in order to be connected in connection with the possible plug shapes, e.g. Straight or angled plugs, to have the greatest possible number of possible combinations and arrangements.
  • other orientations to the lighting direction or a main direction of expansion of the lamp housing are also possible.
  • the plug sockets and the adapter connections are compatible, so that, for example, several discharge lamps can be connected to a ballast by means of the external igniters in different lighting directions.
  • the adapter connection or the plug socket is designed as a bayonet lock, the bayonet lock advantageously having a rotatable contact plate so as not to damage the electrical contacts during mechanical locking.
  • FIG. 1 - a schematic representation of a discharge lamp with coupled ballast and basic ignitor
  • Figure 2 is a schematic representation of a discharge lamp with an external igniter coupled
  • Figure 3 is a schematic representation of the operation of several discharge lamps connected to an external igniter on a ballast and basic igniter;
  • Figure 4 is a front and side view of a discharge lamp mechanically and electrically connected to a ballast and basic igniter
  • Figure 5 is a front and side view of a discharge lamp mechanically and electrically connected to an external igniter and electrically connected to a ballast and basic igniter;
  • Figure 6 - a front and back view and a section through a contact plate of an adapter or adapter connection and
  • Figure 7 - a front and back view and a_ section through a carrier plate of an adapter or adapter connection.
  • FIG. 1 shows a schematic illustration of an illumination device B with a ballast and basic ignition device 1, to which a discharge lamp 7 is attached.
  • the ballast and the basic ignitor form two separate electrical components, these are collectively referred to as ballast and basic igniter 1. If one of the two components is referred to separately, these are referred to as ballast la and basic igniter lb.
  • An adapter or adapter connection 2 is arranged on the ballast and basic ignition device 1, which is expediently integrated into the housing, but was shown separately here for reasons of clarity.
  • the discharge lamp 7, including the lamp housing, is fastened via the adapter connection 2 in such a way that a structural unit is produced with the ballast and basic igniter 1.
  • the lighting device B differs from conventional luminaires in that it has a modular structure, by means of which different discharge lamps 7 can be operated on a single ballast and basic ignition device 1.
  • the adapter or adapter connection 2 is designed in such a way that the discharge lamp 7 is mechanically firmly connected to the ballast and basic ignition device 1, so that the lighting device B can be arranged on a tripod or the like.
  • the electrical connection of the discharge lamp 7 with the ballast and basic igniter 1 is likewise carried out via the adapter or adapter connection 2 by means of electrical contact sockets or plugs integrated therein, which have corresponding counter sockets or mating plugs on the discharge lamp 7 or on the ballast and basic igniter 1 be contacted in the mechanical connection of the discharge lamp 7 and ballast and basic igniter 1.
  • FIG. 2 shows a variant of the lighting device B, in which an adapter 3 is connected to the adapter connection 2 of the ballast and ignition device 1 and is connected to an external ignition device 5 via a connecting cable 4.
  • the external ignition device 5 in turn has an adapter or adapter connection 6 which can be mechanically coupled to an adapter of the discharge lamp 7 and via which the discharge lamp 7 can be electrically connected to the external ignition device 5.
  • a direct connection to the current limiting circuit of the ballast la of the ballast and basic igniter 1 is expediently established during operation via an external igniter 5, since the ignition circuit of the basic igniter 1b is not required.
  • only the capacitor of the basic ignition device 1b can be bridged.
  • the adapter or adapter connection to the discharge lamp 7 can also be coupled directly to an adapter or adapter connection of the connecting cable 4, a direct connection of the discharge lamp 7 to the adapter 3 of the ballast and basic ignition device 1 can also be established without that the ignition circuit of the ballast and basic igniter 1 is bridged.
  • FIG. 3 shows the arrangement of a plurality of discharge lamps 7, 7 'connected to external igniters 5, 5' via cables 4, 4 'and adapters 3, 3' and adapter connections 2, 2 'on a ballast and igniter 1.
  • the structure corresponds in principle the structure shown in Figure 2, here two external sockets 8, 8 'are arranged on the external ignitors 5, 5', to each of which a connecting cable 4, 4 'can be connected.
  • all socket shapes are suitable; for reasons of modular construction, however, it makes sense to make the plug sockets 8 compatible with the adapter connections 2, since this creates a multitude of arrangement options. _
  • FIG. 4 shows a front and side view of a discharge lamp 7 which is mechanically and electrically directly coupled to a ballast and base igniter 1.
  • the coupling takes place via an adapter with mechanical and electrical connecting elements on the ballast and base igniter 1 and on the discharge lamp 7
  • the ballast and basic ignition device 1 has a joint for connection to a tripod or to a suspension of the lighting device.
  • FIG. 5 shows a front and side view of a discharge lamp 7 which is mechanically and electrically connected to an external igniter 5 and a ballast and basic igniter 1 which is electrically connected to the external igniter 5 via a connecting cable 4.
  • the length of the connecting cable 4 is 3.5 or 7 meters.
  • the lighting device formed from ballast and basic ignition device 1 and discharge lamp 7 is approximately 200 mm
  • the lighting device composed of discharge lamp 7 and external ignition device 5 in FIG. 5 has a length of only approximately 96 mm.
  • the connection of the individual components of the illumination device can be effected through a variety of sockets and the adapter or adapter connection, depending on whether a purely ⁇ electric or electrical and mechanical connection according to the Subject of the invention is provided.
