Definitions

  • the invention concerns a portable electric torch, particularly for underwater use.
  • Portable electric torches at present in use are generally fed by rechargeable or non rechargeable battery sets, which feed with current incandescent lamps, provided in a convenient number and arranged on a suitable reflecting parabola, depending on the kind of torch concerned.
  • the main problem with said torches is the operating life of said battery sets, even between consecutive rechargings if rechargeable batteries are concerned, said life being at present rather limited.
  • incandescent lamps which absorb a high power amount, are used as the light sources.
  • said incandescent lamps generally are mounted on a reflecting parabola in order to create an effective directional light beam.
  • the object of the present invention is to remedy said drawbacks, by providing a portable electric torch, particularly for underwater use, which has a substantially longer life, about three times longer, than the average life of a present portable electric torch, and in which mounting the light sources onto a parabola to create the light beam is not required.
  • the main feature of the portable electric torch concerned is that a plurality of LEDs (Light Emitting Diodes) are used as light source, said LEDs being connected in parallel, being arranged on the front parabola of the torch and being fed by a suitable power source, such as a rechargeable or non-rechargeable battery set.
  • a suitable power source such as a rechargeable or non-rechargeable battery set.
  • LEDs are arranged in concentric arrays on the front parabola of the torch.
  • a further feature of the torch concerned is that said front parabola of the torch, on which the LEDs are mounted, may be a non-reflecting parabola since said LEDs emit by themselves directional light.
  • the portable electric torch 1 concerned is substantially similar to a portable torch presently in use, and comprises a cylindrical housing, provided in its front part with a parabola 3 bearing the LEDs 5 and connected through a male fitting 7 to the feeding circuit 9, which in turn is connected through another male fitting 11 to the battery set 13.
  • Said LEDs are connected in parallel and are obviously fed by the battery set 13 through the feeding circuit 9, of course equipped with a spring push-button 15 for turning the torch 1 on.
  • Said LEDs 5 are arranged in concentric arrays on the front part of the parabola 3, and the number of said LEDs is greater or smaller depending on the LED type concerned.
  • a cap 17 that can be opened to allow removal and reinsertion of the battery set 13 is provided in the rear part of the cylindrical housing of the torch 1.
  • the parabola 3, on which the plurality of LEDs is mounted may even be a non-reflecting parabola, since said LEDs emit directional light.
  • the LEDs used have a total illumination life of 6 to 12 hours, of which 2 to 4 hours at maximum power, about 2 hours at 50% the maximum power, and 2 to 6 hours of further endurance at 10% the maximum power.
  • said torch at very low voltage, provides a minimum safety light that makes it a signalling instrument, thanks to the very slow self-discharge time (about 10 to 12 hours).
  • the torch according to the invention besides the lower consumption (about 3 times lower) and the longer life (about 3 times longer) if compared to a conventional torch, has also the following advantages:
