Parabolic louver and side light seal

A parabolic louver and side light seal for use in a light fixture housing having at least one tubular light source, wherein said parabolic louver comprises:

• (a) at least one center stringer extending in a longitudinal direction and at least one center baffle extending in a transverse direction, wherein said at least one center stringer and center baffle each comprise two parabolic side walls;
• (b) two side stringers and two end baffles defining an outer perimeter of said parabolic louver;
• (c) a center joint for interconnecting said at least one center stringer and said at least one center baffle;
• (d) a side joint for interconnecting said at least one center stringer to said two end baffles, and said at least one center baffle to said two side stringers, said side joint of at least said center baffle being characterized by a formed hook and one or more protrusions extending outward from lower and upper portions, respectively, of said parabolic side walls at ends thereof;
• wherein said side light seal comprises two side rails, with said two side rails being mounted to the two side stringers of said parabolic louver, each of said two side rails further comprising a side wall extending between a bottom lip and an upper lip, said bottom lip and said upper lip being disposed on opposite sides of said side wall;
• wherein said side stringers and end baffles each comprise a curved side wall extending upward from a base portion and terminating in an upper edge, said base portion and said upper edge being disposed on the same side of said curved side wall and extending parallel to one another;
• wherein said base portion of said side stringer further comprises a curved lip portion extending inward toward said curved side wall to form a channel;
• wherein said formed hook further comprises a notched extension.

A parabolic louver and light seal combination for use in a light fixture housing having at least one tubular light source, comprising:

• (a) two or more center blades forming a parabolic louver, at least two of said blades being perpendicular to one another such that one or more of said blades extends in a longitudinal direction and one or more of said blades extends in a transverse direction;
• (b) four or more peripheral blades forming a periphery of said parabolic louver, at least one of said peripheral blades having a base portion extending outwardly from said periphery and a curved side extending upward from said base portion to thereby form a channel;
• (c) wherein at least one of said center blades is connected to at least one of said peripheral blades by a side joint, said side joint comprising:
• (i) a formed hook extending outward from a lower portion of said center blade, the formed hook designed to engage a bottom edge of a lower opening formed in said peripheral blade
• (ii) one or more protrusions extending outward from an upper portion of said center blade, the one or more protrusions adapted to be disposed through corresponding notches formed in said peripheral blade;
• and
• (e) one or more light seals, each light seal comprising a bottom lip, an upper lip and a side wall therebetween, said bottom lip and said upper lip being disposed on opposite sides of said side wall;
• wherein said bottom lip is positioned within said channel and abuts said formed hook, thereby holding said light seal and said center blade in place;
• and
• wherein said formed hook further comprises a notched extension.

A parabolic louver and light seal combination for use in a light fixture housing having at least one tubular light source, comprising:

• (a) two or more center blades forming a parabolic louver, at least two of said blades being perpendicular to one another such that one or more of said blades extends in a longitudinal direction and one or more of said blades extends in a transverse direction;
• (b) four or more peripheral blades forming a periphery of said parabolic louver, at least one of said peripheral blades having a base portion extending outwardly from said periphery and a curved side extending upward from said base portion to thereby form a channel;
• (c) wherein at least one of said center blades is connected to at least one of said peripheral blades by a side joint, said side joint comprising:
• (i) a formed hook extending outward from a lower portion of said center blade, the formed hook designed to engage a bottom edge of a lower opening formed in said peripheral blade
• (ii) one or more protrusions extending outward from an upper portion of said center blade, the one or more protrusions adapted to be disposed through corresponding notches formed in said peripheral blade;
• and
• (e) one or more light seals, each light seal comprising a bottom lip, an upper lip and a side wall therebetween, said bottom lip and said upper lip being disposed on opposite sides of said side wall;
• wherein said bottom lip is positioned within said channel and abuts said formed hook, thereby holding said light seal and said center blade in place;
• and
• wherein said one or more light seals further comprises at least one emboss protruding outward from said side wall, said emboss being adapted to extend over said formed hook open to hold said center blade in place.

A parabolic louver and side light seal for use in a light fixture housing having at least one tubular light source, wherein said parabolic louver and side light seal comprises:

• (a) at least one side light seal comprising a bottom lip, an upper lip and a side wall therebetween, said bottom lip and said upper lip being disposed on opposite sides of said side wall;
• (b) at least one center stringer extending in a longitudinal direction and at least one center baffle extending in a transverse direction, wherein said at least one center stringer and center baffle each comprise two parabolic side walls;
• (c) two side stringers and two end baffles defining an outer perimeter of said parabolic louver, said side stringers and end baffles each comprising a curved side wall extending upward from a base portion and terminating in an upper edge, said base portion and said upper edge being disposed on the same side of said curved side wall and extending parallel to one another, and at least one of said side stringers further comprising a curved lip portion extending inward from an outer edge of said base portion to form a channel;
• (d) a center joint for interconnecting said at least one center stringer and said at least one center baffle;
• and
• (e) a side joint for interconnecting said at least one center baffle to said two side stringers, said side joint being characterized by a formed hook and one or more protrusions extending outward from lower and upper portions, respectively, of said parabolic side walls at ends thereof, said formed hook being designed to engage a bottom edge of a lower opening formed in at least one of said two side stringers;
• and said protrusions being adapted to be disposed through a corresponding one or more notches formed in at least one of said two side stringers;
• wherein said channel is adapted to receive said bottom lip;
• and
• wherein at least one of said side light seals further comprises an emboss protruding outward from said side wall, said emboss being adapted to extend over said formed hook when said at least one center baffle is interconnected to each of said two side stringers.
