Abstract

The present invention relates to a light buoy or float for night tracking at sea, lakes or rivers. The aim of the invention is to create a light buoy with unfailing reliability and high efficiency for locating at night, at sea, rivers, lakes, etc. (all liquid elements), of an object or submerged body; with the important particularity of becoming luminous as soon as it is immersed in water, and that without intervention of any kind. The light buoy consists of a bulky hollow body 1 which contains in its tapered lower part an accumulator or battery 2, the negative pole of which is connected to a metallic piano wire 3 forming a loop at its lower part. A metal ring 8 connected to a bulb and in particular a light-emitting diode LED 6 surrounds the lower part of the buoy. The upper part of the buoy has a reflector 4 surmounted by a sphere of transparent material 5. A resistor 7 with an approximate value of 500 ohms is inserted on the circuit between the LED and the positive pole of the battery. This for a longer life of said battery in seawater (approximately 48 hours) without affecting the intensity of the luminous flux of the LED.

LIGHT BUOY.

  The present invention has for d91et a light buoy or

  float for tracking night at sea, lakes or rivers.

  The aim of the invention is to create a luminous buoy of reliable reliability and a great efficiency for tracking night, sea, rivers, lakes etc .... (all liquid elements), a object or submerged body; with the important feature of becoming luminous as soon as it is immersed

  in the water, and without any intervention of any kind.

  The light buoy consists of a bulky hollow body (1) which contains in its tapered lower part an accumulator or battery (2) whose negative pole is connected to a metal piano wire (3) forming a loop at its lower part . A metal ring (8) connected to a bulb and in particular an LED (6) surrounds the

lower part of the buoy.

  The upper part of the buoy comprises a reflector (4) surmounted by a sphere of transparent material (5). A resistor (7) with an approximate value of 500 ohms is interposed on the circuit between the LED and the positive pole of the battery. This for a longer life of said battery seawater (48 hours) without affecting the intensity of the LED light flow. o In fact, it must be known that the resistivity of the water or aquatic medium between the two electrodes (3) and (8) makes it necessary to provide an accumulator or battery of 6 volts for the good

running an LED of I volt 5.

  In (9), finally, is the approximate level of

Flotation of the buoy.

  Note that the tapered shape of the buoy, the weight of the stack, the ring (8) and the piano wire (3) places the center of gravity low enough so that the light buoy is always in operating position (immersion of the lower part comprising the piano string (3) and the metal ring (8) which allows the passage permanently

  current through the aquatic environment).

  -2 - the flow of air at the same time as the body organ

  an autoimmune sensitization by the aquatious medium.

  "e circuit disc) itinu consists of a mechanical ring (F)

  the shell of the flotante body (1), which La5ue is connected to the illuminating organ (6) and, by this orane to one of pl-eb ue the

battery of ali.ientatiin (2).

  On the other hand, at the location of the site, a

  metal organ (3) has extended, from that pole, to the

lower part of the floating body.

  This) aallallian body (3) constituted by eenemple of a tibe, of the type corue a piano, is in contact with the pole in question at the battery u'ali.ientation, and protrudes under the shell, for

  to be removed by an anchoring ring of an iilin or uczre.

  This school is made up of a shell of the same length

  conical hollow and étanc.e, made of plastic material, This shell could be de for.! e di'erent, (cylinurique or other)

and re ": material di erent.

  This light oouée, renéeue solicaire pa exe.lple, of a

  traditional lifejacket, with a snap rope

  It has been arranged on the axis of the piano horn (3) can provide a reading of the following two extremes in the field and thus

18 new ones around.

  The advantage of this system is, on the one hand, its ability to

  tute éoreuve, and other) art, which is its particularity imipor-

  aunt, to be subject to no interference of any kind whatsoever. No manual or mechanical contact, the fact is:

  immersion ensures its operation.

  The tracking to the nauifraged, conscious or unconscious is assured.
