Definitions

  • the present invention relates to a marker beacon, and more particularly to an illuminated marker beacon.
  • a marker beacon is a type of beacon which in recent years has been standadized in Sweden to the form of pyramidal box having a height of about 1.5 meters. Certain beacons, such as pyramidal marker beacons, are illuminated at night, so as to be more readily seen by those at sea.
  • the marker beacon In order to make the marker beacon visible at night, it is illuminated with the aid of a lighting arrangement or lamp unit, such as a halogen lamp, which shines with a relatively white light.
  • a lighting arrangement or lamp unit such as a halogen lamp
  • a beacon which is illuminated in this way can only be seen from a distance of about 1.5 nautical miles.
  • the naked eye sees progressively more and more white in the light emanating from the beacon, and consequently progressively less red light.
  • the beacon is seen as a white lamp, resembling approximately a stationary street lamp or some other source of white light.
  • DE-A-17 66 816 a screen is shown which is intended to be illuminated by ultraviolet light.
  • the screen contains fluorescent particles.
  • DE 17 66 816 there is no suggestion in DE 17 66 816 of how to improve the visibility at long distances.
  • the present invention relates to a marker beacon for sea navigation purposes, which incorporates one or more planar surfaces making an angle to the horizontal plane and which planar surfaces are intended to be seen by those at sea, characterized by the combination in which said surfaces are coated with a fluorescent paint, in a manner known per se, which paint transmits light of visible wavelength when irradiated with ultraviolet light, in which a lighting arrangement is provided for irradiating said surfaces with light containing a high proportion of ultraviolet light, in which the light source of the lighting arrangement, optionally in combination with a cover glass, is arranged so as to transmit substantially no light within the visible light spectrum.
  • Figure 1 shows a marker beacon 1 as seen from one side, i.e. as seen by those on the seaward side of the beacon.
  • Figure 2 shows the beacon 1 from above.
  • a marker beacon 1 of substantially pyramidal configuration and having a square cross-sectional shape in the horizontal plane, as shown in Figure 2.
  • the beacon suitably comprises three sheet-metal side panels 2, 3, 4. Each of the panels has the shape of an equilateral triangle, with a side length of 1.8 meters. This construction is used in those cases when the side 5 to which no panel is fitted faces inland.
  • the beacon may be fitted with two or four side panels.
  • the outer surfaces of respective panels 2, 3, 4 are coated with a paint which fluoresces when irradiated with ultraviolet light and reflects light having a wavelength which lies within the visible spectrum, i.e. a so-called daylight luminous paint.
  • the paint used is preferably one which when irradiated with ultraviolet light, transmits light within the red region of the spectrum.
  • the illustrated beacon incorporates a lighting arrangement 6, 7, 8 for the transmission of ultraviolet light.
  • the lighting includes, for example, two lamp units 7, 8, each of which comprises a light source in the form of a mercury lamp.
  • the lighting arrangement is preferably constructed to transmit light in the wavelength band of 360-370 nanometers.
  • the lighting arrangement is so constructed that the light source, optionally in combination with the cover glass of the lamp units, transmits no light within the visible spectrum. This means that no part of the surroundings will be illuminated in a manner discernible to the eye.
  • the lamp units are suitably carried by a frame 6 and are so mounted that the light passing through respective light apertures illuminates all the side panels 2, 3, 4 of the beacon.
  • an advantage is gained when the lamp units are constructed so that substantially all light transmitted falls within the sectors indicated in broken lines in Figure 1, since ultraviolet light which falls outside the beacon serves no useful purpose.
  • a marker beacon constructed in accordance with the invention is a remarkable improvement on beacons illuminated with white light, especially during the dark hours.
  • the beacon Since the surroundings are not illuminated in a manner to be visible to the eye, the beacon is seen only as an intensive red light. In addition to being visible over distances which are four times greater than those possible when using visible light, the beacon can be readily distinguished from other fixed land lighting.
  • a marker beacon according to the invention thus constitutes a remarkable improvement for those at sea.
  • the marker beacon has been described by way of an example as having a pyramidal form, although it will be understood that beacons of other configurations and other types also fall within the scope of the invention.
