Adjustable light fixture and lighting system

An adjustable light fixture, comprising:

• a housing having;
• (i) a housing axis,
• (ii) a first portion having a length along said housing axis, and
• (iii) a second portion having a length along said housing axis and selectively engageable with said first portion along said housing axis;
• a tray mountable to said housing and having:
• (i) a tray axis parallel to said housing axis,
• (ii) a first plate having:
• a. a first side and a second side;
• b. a plurality of electroluminescent light sources disposed in an even distribution along said first side;
• c. a first slot extending between said first side and said second side along at least a portion of the length thereof parallel to said longitudinal axis;
• d. a first locking pin extending outwardly from at least one of said first and second sides;
• and
• (iii) a second plate selectively engageable with said first plate and movable relative to said first plate along said tray axis, said second plate having:
• a. a first side and a second side;
• b. a plurality of electroluminescent light sources disposed in an even distribution along said first side;
• c. a second slot extending between said first side and said second side along at least a portion of the length thereof parallel to said longitudinal axis;
• and
• d. a second locking pin extending outwardly from at least one of said first and second sides;
• and
• said respective first and second slots adapted to receive respective second and first locking pins;
• said first and second plates combinable to provide continuous and uniformly luminous light from said tray along said tray axis irrespective of placement of said first plate relative to said second plate;
• and
• said tray mountable to said housing such that said second sides of said first and second plates face said housing.

A method of installing a lighting system in a defined space to be illuminated, comprising:

• selecting at least one adjustable light fixture;
• defining a target region in said defined space;
• moving first and second plates of a tray of said adjustable light fixture relative to one another along first and second slots in said first and second plates, respectively, along a tray axis to a selected tray length corresponding to said target region, wherein each of said first and second plates has a plurality of electroluminescent light sources disposed uniformly there along;
• mounting said tray having said selected tray length to said target region of said defined space;
• and
• forming a uniform light distribution along said defined space emanating from said adjustable light fixture.
