Abstract
Disclosed is a lighting fixture () with a separately controllable set of LED-based light sources () configurable to create both downlighting and wall-washing lighting effects. To create the desired wall-washing effects, the intensity and angle of light sources in the lighting fixture are adjusted to individually illuminate different portions of the wall of surface. One set of LED-based light sources positioned along the edge of the ceiling tile is configured to emit a low intensity light beam toward the upper portion of the wall surface adjacent the ceiling. Another set of LED-based light sources emits a higher intensity light beam toward an intermediate portion of the wall surface. Another set of LED-based light sources emits an even higher intensity light beam toward the bottom portion of the wall surface.
