A range of luminary proposes using a same housing to obtain different beams by changing the reflector in the factory (the luminary have the same beam during all its life) or displacing the position of the lamp (some positions giving unlucky lighting effect).
The invention proposes to transform the beam only by choosing a predefined shape of one or more elastic segments (facet's in a reflector) allowing 2 or more different beams with the same piece.
A curved shape made of elastic reflective material maintained at one or more edges of the reflector is used, which can take 2 stable positions.
