ABSTRACT:
A recessed light fixture has an outer housing adapted to be fixedly mounted in a hole in a wall or ceiling and centered on an axis, an inner lamp holder provided with a socket for a light bulb and centered on an axis, and a pair of stiff links of different lengths each having an inner end pivoted on the housing and an outer end pivoted on the holder for movement of the holder between an inner position recessed in the housing with the holder and housing axes generally coaxial and an outer position outside the housing with the axis inclined to each other and through intermediate positions such that as the holder moves outward the angle its axis forms with the housing axis increases and as it moves inward the angle its axis forms with the housing axis decreases. Each intermediate position corresponds to a particular angular orientation of the holder axis to the housing axis, that is the inward/outward movement and pivoting movement are dependent on each other so that each angular position corresponds to one and only one in-to-out position.
