Abstract (en)
A louver (10) may be installed on or within a light fixture (20) containing a light emitting diode (LED) light engine (22) to distribute and diffuse light. The louver (10) includes a number of individual fins (14) that define apertures (16) within the louver (10). The louver (10) is positioned sufficiently close to LEDs (24) provided with the light fixture (20) so that high angle light emission from the LEDs (24) may be blocked, reflected, refracted, or otherwise managed.
