Definitions

  • the present invention relates to an emergency light with its own emergency power source and automatic, electronic switching and charging circuit.
  • emergency lights with their own emergency power source of the aforementioned type are also state of the art (so-called single battery system).
  • These known emergency lights are either designed as independent, individually mounted lights, or kits are used for installation within normal, mains-powered lights.
  • the first case it is necessary to lay special power cables to each emergency light, which means a high additional installation effort.
  • the second case the selection of luminaires that can be used is severely restricted, and the arrangement of the emergency luminaires is local, which means that they are always in the place of normal luminaires (e.g. on the ceiling), which often does not meet the requirements for safety or replacement lighting in the event of a power failure corresponds (display of an escape route in the building, lighting of workplaces with risk of accident, etc.).
  • Emergency lights are also known ( FR-A-1 264 752 ) which have their own emergency power source and an automatic, electronic switching and charging circuit. These are designed as plug-in units and can be inserted into existing sockets. It is considered a disadvantage that such units can be replaced by unauthorized persons and that there is an increased security risk, which is not tolerable with emergency light arrangements.
  • the aim of the invention is to avoid the disadvantages of the known designs mentioned and to create an emergency lighting system corresponding to increased safety requirements at a comparatively low cost and at to allow free choice of luminaire locations.
  • This object is achieved according to the invention with an emergency light of the type mentioned at the outset with the features of claim 1.
  • the emergency luminaires Thanks to such a design of the emergency luminaires, their assembly and arrangement can largely take place in the course of normal power line laying and apparatus installation, i.e. the emergency lights are preferably installed along the network installation to be created anyway and adjacent to sockets, light switches, junction boxes, etc.
  • the built-in unit of the emergency light can therefore be connected to the external voltage (mains voltage) in an existing equipment box without additional installation effort.
  • the low effort allows the installation of a larger number of emergency lights without any problems, which also enables a more uniform illuminance of the emergency light to be achieved.
  • the built-in unit 10 is built on a printed circuit board 11 and contains in particular its own emergency power source - here consisting of two rechargeable cells 12 -, mains connection terminals 13 and a lamp holder 14 which is preferably arranged centrally on the printed circuit board 11. Otherwise, the printed circuit board 11 with the ones here is not switching elements of an automatic, electronic switching and charging circuit shown in detail according to the diagram of FIG. 4; In Fig. 1, only a light-emitting diode 16 as an operating display element and an operating switch 17 are visible from this circuit.
  • the unit 10 is received for the installation by the insulating housing 6, which fits into the equipment box 1 and in particular serves to separate the unit 10 from mains cables which are laid in the bottom of the box 1.
  • the unit 10 is connected to the mains through housing openings 8 at the terminals 13.
  • the mechanical fastening is carried out, as with other built-in apparatus (light switch, socket, etc.), on the eyelets 4 of the mounting frame 3 which fits onto the flange 2 of the socket 1.
  • the insulating housing 6 has For this purpose, two screw holes 7, and preferably two further holes 7 'fitting on the eyelets 4', so that the unit 10 can optionally be installed in two positions offset by 90 °.
  • the cover 20 of the emergency light has the outer shape of a normal cover plate, as it is also used for switches and sockets, etc. for flush mounting.
  • the shield has a light exit opening 21 which is aligned with the lamp holder 14, ie preferably in the center, through which a part of the bulb of the emergency lamp 15 projects.
  • a further opening 22 next to the opening 21 is covered by a (partially broken away) dome light 23, which on Shield 20 is attached and consists of translucent, for example light-diffusing shaped material.
  • the shield 20 and / or the dome 23 can be provided with a label or, for example, an escape route symbol or the like.
  • the openings 21 and 22 can be arranged side by side or one above the other.
  • the operating switch 17 is actuated only before the emergency light is installed and is inaccessible in the installed state.
  • cover plate 20 in view.
  • a combined cover plate 20 ' can of course be used if the emergency light is installed next to another device.
  • the cover can e.g. in the case of more extensive apparatus combinations, it can also be part of a control panel or the like.
  • FIG. 2 is a top view of the unit 10 that can be installed. As can be seen, it or its circuit board 11 can be prepared for surface mounting by means of screws 18. In that case, the associated luminaire cover is expediently designed with the outer dimensions of a surface-mounted apparatus housing, but with corresponding openings and a dome light (not shown).
  • the circuit of a suitable electronic switching and charging circuit according to FIG. 4 is known per se, for which reason the mode of operation is only briefly explained below:
  • the rectifier bridge G is connected to the AC network via series resistors by means of terminals 13. It normally generates a DC charging voltage for the emergency supply battery 12.
  • the live LED 16 indicates normal operation.
  • a control circuit with the npn transistor T1 and the pnp transistor T2 is set in such a way that T2 is blocked as long as the rectifier bridge G generates the charging voltage when the mains voltage is present.
  • the lamp 15 then remains de-energized.
  • the switch 17 in the circuit of the emergency power source (battery 12) remains during the entire operating period, i.e. since the installation and connection of the emergency light, closed; for this reason the switch should remain inaccessible. It only has one function during the storage period before installation: For reasons of functional reliability, it is advisable to connect the cells 12 firmly in the circuit (using a welded or soldered connection). The unit 10 is therefore already equipped with the cells 12 during manufacture.
  • the switch 17 is opened after the cells 12 have been charged for the first time and is only closed after the emergency light has been connected and installed in order to establish the operational readiness.
  • a pluggable or solderable contact bridge could be provided on the printed circuit board 11.
  • Parts of the switching and charging circuit according to FIG. 4 can, of course, also be constructed as an integrated circuit (chip) instead of individual components (FIG. 2).
  • the equipment box for surface or flush mounting which accommodates the unit 10, can also be designed to be drip-proof, splash-proof, water-jet-proof, water-tight or explosion-proof, depending on the requirements.
