Abstract
Techniques for using variable flower assemblies to control light leakage between designated portions of light-emitting elements are provided. In some embodiments, a variable flower assembly () comprises a plurality of light-transmissive segments (---) each may be electronically set to a different light-transparency level. The variable flower assembly substantially forms a tube around a light-emitting element () mounted on a first plane. A first edge of each of the light-transmissive segments collectively surrounds the light-emitting element on a second plane substantially parallel to the first plane. A second opposing edge of each of the light-transmissive segments collectively forms an opening of the tube. In some embodiments, a reflective assembly () which reflectance level is electronically controllable may surround the variable flower assembly.
