Abstract:
1. An adjustable luminaire comprising: a base; a tubular arm movably connected to the base; a light assembly connected to the tubular arm, the light assembly having at least two light shades pivoted relative to each other and a plurality of light sources disposed on the at least two light shades for providing illumination; and a driving assembly mounted in the tubular arm and the base, the driving assembly movably connected to the light assembly, the driving assembly moved with the movement of the tubular arm to drive the light assembly for adjusting a pivoting angle between the at least two light shades so as to vary an illuminated area of the light assembly; wherein when the tubular arm is moved upwardly relative to the base, the light assembly is driven by the driving assembly such that the pivoting angle between the at least two light shades is relatively changed for gradually contracting the illuminated area; when the tubular arm is moved downwardly relative to the base, the light assembly is driven by the driving assembly such that the pivoting angle between the at least two light shades is relatively changed for gradually expanding the illuminated area.
