Title: LIGHTING ASSEMBLY WITH DIFFERING LIGHT OUTPUT DISTRIBUTION AND/OR SPECTRUM OUTPUT
Abstract:
A lighting assembly (100) includes a light guide (102) having opposed major surfaces (106, 108), a light input edge extending between the major surfaces (106, 108) and including first and second input regions (110A, HOB), a first light guide region (102A) associated with the first input region (110A) and including first light extracting elements (124), and a second light guide region (102B) associated with the second input region (HOB) and including second light extracting elements (124). A first light source segment (104A) is arranged to input light through the first input region (110A) and into the first light guide region (102A), and a second light source segment (104B) is arranged to input light through the second input region (HOB) and into the second light guide region (102B). The first light source segment (104A) and the second light source segment (104B) are independently controllable to control an illumination state of the solid- state light emitters (104).
