Methods and apparatus for small aperture lighting having variable vertical adjustability

A housing assembly for a recessed lighting apparatus, the housing assembly comprising:

• a housing defining a cavity and an aperture to access the cavity, the housing comprising:
• a rail;
• a heatsink subassembly disposed in the cavity of the housing and slidably coupled to the rail, the heatsink subassembly being configured to support a lighting module and a trim;
• and
• a cantilever spring directly coupled to the rail, the cantilever spring physically contacting a bottom portion of the heatsink subassembly and configured to apply a force causing the heatsink subassembly, the lighting module, and the trim to move along the rail when the lighting module is coupled to the heatsink subassembly.

A housing assembly to facilitate installation of a recessed lighting apparatus in a ceiling space, the housing assembly comprising:

• a housing defining a cavity and an aperture to access the cavity;
• a heatsink subassembly disposed in the cavity of the housing and movably coupled to the housing along a vertical axis when the housing assembly is installed in the ceiling space, the heatsink subassembly being configured to support a lighting module when the lighting module is at least partially inserted through the aperture of the housing and a trim coupled to the lighting module;
• and
• a spring disposed in the cavity of the housing and coupled to the heatsink subassembly, the spring being configured to apply a force to cause the heatsink subassembly, the lighting module, and the trim to move vertically upward along the vertical axis until a portion of the trim physically contacts a bottom surface of a drywall enclosing the ceiling space when the lighting module is at least partially inserted through the aperture,
• wherein:
• the aperture has a width ranging from about 1.8 inches to about 2.2 inches;
• the housing has a height ranging from about 2.2 inches to about 2.8 inches;
• and
• the heatsink subassembly has a range of travel along the vertical axis ranging from about 1 inch to about 1.25 inches.
