Definitions

  • the following invention relates to a focusing device for the light beam in illumination elements with damp chamber, the illumination element, such as a torch, being of the type which has a light emitter and a chamber with a fluid, such as ambient air or water, for different uses, among which are to be found its use in underwater activities, such that the focusing device is defined by a plano-convex lens mounted in a tubular body, whose position can be axially adjusted with respect to the light emitter.
  • the said tubular body in which the plano-convex lens is mounted is external to the illumination body (for example a torch) with respect to the ambient air or water chamber.
  • the light emitter will be able to consist of several LEDs and, when the position of the plano-convex lens is adjusted, moving it further away or closer to the light emitter, a variable beam is provided that can be adjusted to the needs of the user and, moreover, the focusing will be carried out perfectly.
  • the present specification describes a focusing device for the light beam in illumination elements with damp chamber, whose illumination element, such as a torch, will be able to be of use in carrying out different activities, among which is its application in underwater activities due to being provided with a chamber with a fluid, such as ambient air or water.
  • focusing torches of utility for, among other uses, underwater activities have an illumination bulb with an aluminum reflector and a water chamber, in such a way that the focusing can be regulated at the will of the user by means of a rotary movement of the head of the torch body which moves the optic (light emitter) closer to or further away from the reflector, permitting the light beam to be opened or closed.
  • focusing torches for underwater activities have to meet a series of characteristics such as the optic having the appropriate watertightness, incorporating a damp chamber and being adjustable with respect to the aluminum reflector moving it closer to or further away from said aluminum reflector by means of rotating the head of the torch body.
  • the light emitter When carrying out the adjustment of the optical system by means of rotating the head of the torch, if the light emitter consists of several optics it is not possible to obtain a concentrated beam, being valid for emitters based on a single light emitter.
  • the present specification describes a focusing device for the light beam in illumination elements with damp chamber, being of the type of lighting elements, such as torches, in which the light emitter is protected by a lens and incorporates a chamber with a fluid, such as ambient air or water, so that, with respect to the damp chamber, the body of the illumination element incorporates externally a hollow tubular body in which a plano-convex lens is assembled and that is axially displaceable and defines a damp chamber between the protective lens of the light emitter and the focusing lens.
  • the hollow tubular body presents an axial slot in which fits a projection of the torch body for the perfect axial guiding of the tubular body with respect to the body of the illumination element, in the focusing of the light emitter.
  • the axial displacement of the tubular body for the focusing of the light emitter allows the light beam to be focused independently of the number of light emitters that it comprises. So, if the light emitter consists of four LEDs the beam provided in the focusing will be perfectly centered, what that does not occur when focusing by means of rotating the focusing lens.
  • the damp chamber houses a fluid, such as ambient air or water, which is connected to the hollow tubular body in such a way that in the axial displacement of the tubular body the fluid can circulate between the damp chamber and the hollow interior of the tubular body, compensating the pressure.
  • a fluid such as ambient air or water
  • the body of the illumination element 1 incorporates the light emitter 2 which is protected by a protective lens 3 and it incorporates externally to the torch body 1 a hollow tubular body 4 in which a plano-convex focusing lens 5 is assembled, being said hollow tubular body 4 axially displaceable.
  • the hollow tubular body 4 is assembled with respect to the light emitter 2 and defines, between the protective lens 3 and the focusing lens 5, a damp chamber 6 for housing a fluid, such as ambient air or water.
  • said tubular body 4 is provided with an axial slot 8 in which fits a projection 9 of the torch body 1, in such a way that said axial movement of the plano-convex focusing lens 5 which is assembled to the tubular body 4, provides a variable beam that can be adjusted to the needs of the user.
  • the tubular body 4 moves axially, with no any rotation, perfectly guided by the projection 9 which fits in the axial slot 8 and the fluid housed in the chamber 6 will be able to circulate to the interior 10 of the tubular body 4, being both of them connected.
  • the focusing device in illumination elements can have the focusing "damp” or “exposed” chamber, and is of application in different situations among which is its use in underwater activities, so that an important advantage is that it improves the protection of the emitter and facilitates the focusing.
