Definitions

  • Lighting device in particular for ships
  • the invention relates to a lighting device for vehicles, in particular water and aircraft, in particular ships, the lights of which are each connected to an energy source via a connecting line.
  • each ship has a variety of different lights, some of which generally used for general lighting purposes (interior lighting, deck lighting, etc.), to some extent have labeling or signaling functions (e.g. position lights, rear lights, signal lights, the latter, if necessary, with dimming devices, etc.), and the when traveling, in particular military ships also serve as guidance.
  • labeling or signaling functions e.g. position lights, rear lights, signal lights, the latter, if necessary, with dimming devices, etc.
  • Spare sheet The latter are often difficult to reach, especially at sea, if, for example, there are signal lights which are arranged at a height above the top deck on a deck structure, or if they are arranged outboard. Since it is very difficult, particularly in such cases, to replace a defective incandescent lamp, signal lights or the like can be seen in the case of signal lights which are particularly difficult to access. often already a second lamp from the outset. (as a replacement lamp), to which it may be possible to switch. However, this requires an unsatisfactorily high investment outlay, since such replacement lights must also be wired separately, at least in sections, so that they can be put into operation if necessary.
  • a further disadvantage of known lighting devices for ships and airplanes is that the connecting lines between the lights and the energy source, which are either an accumulator, a generator or a power supply network fed by them, are, as it were, antennas which accordingly act on External electromagnetic fields react.
  • the E V pulses captured thereby can possibly be so strong that not only temporary malfunctions of the lighting system, but even permanent damage can occur.
  • semiconductors used in the lighting device react extremely sensitively to the resulting voltage peaks. With relatively large voltage peaks, the semiconductors and possibly other components of the lighting system can even be destroyed.
  • the present invention is therefore based on the object of improving a lighting device of the type described at the outset, while avoiding its disadvantages, in particular in such a way that the lighting system is insensitive to external electromagnetic fields, so that it does not result in corresponding interference or even (possibly considerable) damage can come, and that it with difficult to access lights, such as one on a mast or the like. attached signal light, no longer comes to the previous difficulties, without this requiring double investments.
  • the solution to this problem is characterized in accordance with the invention in that the actual electrical energy source is followed by a high-power light source, each of which is connected to at least one lamp via a glass fiber cable, the high-power light source being followed by a filter by means of which the light sources which do not or only insignificantly contribute to the generation of visible light are to be filtered out before entering the glass fiber cable (s).
  • the light generated by strong light sources when it is passed on can cause the fiber optic cables to heat up to such an extent that they are damaged or even destroyed, at least in the long run.
  • the light source of a luminaire can be arranged in an easily accessible location, all the difficulties that were necessary in lighting systems (in particular on ships) in the case of luminaires which are difficult to access are eliminated, while at the same time the investments for replacement luminaires are eliminated can be avoided.
  • the lighting system according to the invention is evidently completely independent of external electromagnetic fields, so that they cannot adversely affect the lighting device even if they are of considerable strength, which would lead to destruction in known lighting devices.
  • the heating of the optical fiber cables is harmless, since the infrared rays which are harmful and cannot be used in terms of lighting technology are filtered out before they enter the optical fiber cable.
  • An essentially punctiform light source is preferably provided as the high-power light source, since the usable solid angle of a suitable optical fiber cable, for example with a diameter of 2 mm, is quite small, and preferably a noble gas high-power light source (for example, a metal halide or xenon vapor lamp) that can be used to generate many millions of candelas (Cd), or a mercury short-arc lamp.
  • a reflector can be arranged between the high-power light source and the fiber optic cable input, with which light originating from the light source can be directed into the fiber optic cable in a targeted manner and can therefore be passed on to any critical point without difficulty.
  • the lighting system according to the invention is also extremely interesting from an economic point of view, since its use - apart from the double investments for replacement lights mentioned above - makes considerable savings.
  • the reading lights in commercial aircraft for which currently due to complex microprocessor monitoring. about 150 USg / piece are to be made considerably cheaper when using the lighting system according to the invention, for example if they are fed directly with light from the cockpit via glass fiber cables.
  • the drawing shows a lighting device, generally designated 1, for a vehicle, generally designated 2, such as a ship or an aircraft, the (numerous) lights 3 thereof, of which in the schematic drawing
  • all lights 3 are powered by this (Single) lighting device 3 fed so that it must produce a very large light output or a very large luminous flux of a few 100,000 Cd, which can easily exceed the million mark for larger ships.
  • the point light source 6 1 is followed by a filter 7, which is designed in such a way that light source lengths> approx. 780 nanometers are to be filtered, which are infrared waves 8, which would otherwise cause harmful heating, so that essentially only "cold" light waves 9 enter the glass fiber cable 4 'arrive.
  • the filter 7 is designed as a liquid filter and is cooled by means of a cooling system -10.
  • a second cooling system 11 is also provided for the high-power light source 6, the two cooling systems 10, 11 possibly by means of bypass lines 12 can be connected, as this is indicated in the drawing with dashed lines.
  • a lens system 13 is arranged downstream of the filter 7 (this can optionally also be arranged upstream of the filter 7), with which the light emitted by the punctiform light source 6 * can be bundled onto the entry point 14 of the glass fiber cable 4 in order to use the solid angle of the glass fiber cable To be able to make optimal use of 4 *.
  • the lighting device according to the invention provides lighting for all types of ships (including ships for military use), but also for aircraft, etc. device, which avoids all disadvantages of known lighting devices while creating numerous advantages, the division of the light generated by the lighting device into the individual lamps 3 being of no difficulty and practically loss-free to carry out and which has hitherto been high for fiber optic cable light technology Problems existing light outputs are optimally solved according to the invention.

Abstract

Un agencement d'éclairage (1) pour véhicules, en particulier pour engins maritimes et aéronefs, notamment bateaux, comprend des lampes reliées chacune par une ligne de connexion à une source d'énergie (5) associée à une source de lumière (6) de haute puissance située en aval et reliée par des câbles de fibres de verre (4, 4') à au moins une des lampes (3). Un filtre (7) agencé en aval de la source de lumière (6) filtre les ondes de lumière qui ne contribuent guère ou pas à générer la lumière visible avant leur entrée dans le câble de fibres de verre (4').
