Selectively-extendable modular lighting fixture

A lighting fixture comprising:

• an elongate modular housing having sidewalls and lengthwise ends;
• an elongate lens fitted to the housing and having lengthwise end edge portions;
• and
• a pair of unitary endplates each having an inside surface and being attachable to either lengthwise end of the housing, each endplate having a lens supporting structure on the inside surface, each lengthwise end edge portion of the lens being received within the lens supporting structure on the inside surface of the endplate, each endplate having respective perimeter surfaces matingly attached to a bridge for linear extension of the housing, and bridge having an outer surface of substantially the same size as the outer surface of the endplate where the bridge and endplate join.

A lighting fixture comprising:

• an elongate modular housing having sidewalls and lengthwise ends, the sidewalls having downwardly-opening grooves along elongate sides thereof;
• an elongate lens having flanges along two opposite sides thereof with lengthwise end edge portions, the flanges received in the downwardly-opening grooves of the housing;
• and
• a pair of unitary endplates each including an endplate support for supporting a lengthwise end edge portion of the lens, each endplate being attached to either lengthwise end of the housing and having perimeter surfaces matingly attached to:
• (a) a bridge for angularly-directed extension of the housing and having a peripheral edge of substantially the same size and contour as an outer surface of the endplate where the bridge and endplate join,
• (b) a bridge for linear extension of the housing and having a peripheral edge of substantially the same size and contour as the outer surface of the endplate where the bridge and endplate join, or
• (c) an endcap having a peripheral edge of substantially the same size and contour as an outer surface of the endplate where the endcap and endplate join.
