Lighting fixture with adjustable aperture

A recessed lighting fixture operable to emit light through an opening in a surface panel into a room, the light fixture comprising:

• a fixture base having an opening, and having an inside surface;
• an aperture plate extending along the inside surface of the fixture base and having a collar extending through the opening of the fixture base, and the collar defining an aperture;
• a lighting assembly connected to the fixture base and operable to emit light through the aperture;
• the aperture plate being disposed between the fixture base and the lighting assembly;
• the lighting fixture having a longitudinal axis (X), a lateral axis (Y) and a tertiary axis (Z) which are mutually orthogonal, and the longitudinal axis (X) and lateral axis (Y) defining an X-Y plane which is parallel to a plane of the surface panel;
• and
• a position of the aperture plate being adjustable by translation parallel to at least the longitudinal axis (X) and lateral axis (Y) to adjust a position of the collar with respect to the opening in the surface panel;
• whereby the lighting fixture can adapt to variations in the position of the opening in the surface panel without modifying the opening in the surface panel.
