Light mounting assembly with movable tab

A light mounting assembly, comprising:

• a frame having a frame base, a frame inner edge defining a frame opening in said frame base, a frame inner wall extending upwardly from said frame inner edge, a first slot and second slot in said frame inner wall, and a frame flange extending inwardly from said frame inner wall;
• a base having an upper and a lower surface and having first, second, third and fourth outer edges, said base having an opening and an inner edge defining said opening, said first outer edge being opposite said second outer edge, said third outer edge being opposite said fourth outer edge;
• first, third and fourth base walls extending upwardly from said upper surface of said base at said first, third and fourth outer edges and being engagable with said frame flange to align said mounting panel with said frame during installation;
• a second base wall extending upwardly and inwardly from said upper surface of said base at said second outer edge;
• a first tab extending outwardly from said first base wall to engage a first slot in said frame;
• and
• a second tab extending outwardly from said second base wall and being movable between an insertion position within a periphery of said base and an installed position extending laterally from said periphery to engage said second frame slot.

A luminaire assembly, comprising:

• a base having an upper surface and a lower surface and having first, second, third and fourth outer edges, said first outer edge being opposite said second outer edge, said third outer edge being opposite said fourth outer edge, said base having a quadrilateral opening and first, second, third and fourth inner edges defining said opening, said first inner edge being opposite said second inner edge, said third inner edge being opposite said fourth inner edge;
• first, third and fourth walls extending substantially perpendicularly from said upper surface of said first, third and fourth outer edges of said base;
• a second wall extending inwardly from said upper surface of said second outer edge of said base;
• at least one first tab extending outwardly substantially perpendicularly from said first wall for engaging a first slot in a luminaire frame;
• at least one second tab extending outwardly from said second wall for engaging a second slot in the luminaire frame, said at least one second tab being deformable;
• a ballast box positioned on said upper surface of said base above said opening in said base;
• and
• an optical assembly attached to said ballast box.

A light mounting panel for connecting to a luminaire frame, comprising:

• a base having an upper surface and a lower surface and having first, second, third and fourth outer edges, said base having an opening and an inner edge defining said opening, said first outer edge being opposite said second outer edge and said third outer edge being opposite said fourth outer edge;
• a first wall extending from said upper surface of said base at said first outer edge;
• third and fourth walls extending upwardly from said upper surface of said base at said third and fourth outer edges, respectively, and contactable with internal flanges of the existing luminaire frame to align said mounting panel with the existing luminaire frame during installation;
• a second wall extending upwardly and inwardly from said upper surface of said base at said second outer edge;
• a first fixed tab for engaging the luminaire frame;
• and
• a second tab being movable between an insertion position and an installed position for engaging the luminaire frame.

A light mounting panel,

• a base having an upper surface and a lower surface and having first, second, third and fourth outer edges, said base having an opening and an inner edge defining said opening, said first outer edge being opposite said second outer edge and said third outer edge being opposite said fourth outer edge;
• a first wall extending inwardly from said upper surface of said base at said first outer edge;
• third and fourth walls extending upwardly from said upper surface of said base at said third and fourth outer edges, respectively, and contactable with internal flanges of the existing luminaire frame to align said mounting panel with the existing luminaire frame during installation;
• a second wall extending upwardly and inwardly from said upper surface of said base at said first outer edge;
• a first fixed tab extending outwardly from said second wall to engage the luminaire frame internal flanges;
• and
• a second tab extending upwardly from said first wall and being movable between an insertion position and an installed position to engage the luminaire frame internal flanges.
