Abstract
A reflector for light radiation sources, the reflector taking the form, for example, of a cup centered around a main axis with a bottom opening for a source of light radiation, the reflector including a cup-shaped base portion extending from the bottom opening to an outer rim, and an annular portion surrounding the outer rim. The annular portion may be telescopically coupled to the base portion and may be moveable with respect to the base portion along the main axis in order to vary the length over which the annular portion extends along the main axis with respect to the outer rim of the base portion.
