(54)	Focusing device for the light beam in illumination elements with damp chamber

(57) Focusing device for the light beam in illumination elements with damp chamber, of the type of illumination element, such as torches, which consists of a chamber with a fluid, such as ambient air or water, in such a way that the torch body (1) incorporates externally with respect to the light emitter (2) a hollow tubular body (4), axially displaceable, said hollow tubular body (4) holding a plano-convex lens (3) and is connected to the ambient air or water chamber (6), the tubular body (4) including an axial slot (8) in which fits a projection (9) of the torch body (1) so that said axial displacement of the plano-convex focusing lens (5), mounted in the tubular body (4), provides a variable beam that can be adjusted to the needs of the user.
