Abstract (en)

[origin: EP2161491A2] 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.
