Definitions

  • the present invention relates to a warning device and sighting light that may be located on an underwater diving suit or on a balancing jacket (referred to also as "jacket"), so that the diver may be easy to detect and recognize during submersion by other divers.
  • a warning device and sighting light may be located on an underwater diving suit or on a balancing jacket (referred to also as "jacket"), so that the diver may be easy to detect and recognize during submersion by other divers.
  • the present invention thus envisages a warning device and warning light comprising basically a battery which supplies an electric current to a filiform semiconductor element (of the diameter of, for example, 1 or 2 mm) contained in a transparent plastic coating.
  • the said filiform element consists of an electroluminescent semiconductor material, i.e., one that has the property of lighting up if it is traversed and thus excited by an electric current.
  • This filiform element is then coated with a transparent plastic material so as to make the light signals emitted by this semiconductor visible.
  • the coated filiform element may be sewn or otherwise secured to a diving suit, or alternatively to a jacket, and is connected to a battery for supplying the current, for example a single storage cell.
  • the scuba diver may send light signals in the case where he is in difficulty, or anyway wants to make himself visible to other divers who are in submersion.
  • This warning light is also useful in the case where a scuba diver instructor wants to follow the squad of his pupils, recognizing them individually during diving
  • the coated filiform element fastened to the diving suit or jacket may in fact be given any form, such as a symbol (e.g., a letter) or a number, thus enabling recognition of the diver to whom the letter or number is associated.
  • the light warning device is fastened or sewn to a scuba diver balancing jacket, or simply jacket, 1.
  • the said warning device and sighting light basically comprises a battery 2 for supplying the electric current, a switch 3 of the circuit of said warning light, and a filiform element 4 consisting of semiconductor material (having a diameter of, for example, 1 or 2 mm) coated with transparent plastic material.
  • the switch 3 for supplying the circuit.
  • the filiform element takes the form of, for instance, a symbol (letter) 5, which enables recognition of the scuba diver to whom it is associated.
  • Figure 2 shows the warning device and sighting light according to another embodiment which presents a further example of the present invention, fastened or sewn directly to the diving suit 6 in the case, for example, of submersion without using breathing apparatus, whereby the balancing jacket is not used.
  • the warning device and sighting light is made up of the same elements previously described for Figure 1, with the exception of the filiform element 4 consisting of semiconductor material coated with transparent plastic material, which takes the form, for example, of a number 7.
