Abstract:
1. A reflective light shelf adapted for use within an associated building structure adjacent an associated window thereof, said reflective light shelf comprising: a first wall extending longitudinally between opposing first and second ends that at least partially define a shelf length and extending laterally between opposing first and second edges that at least partially define a shelf width, said first wall including an inner surface and an outer surface disposed opposite said inner surface with said outer surface exhibiting a combination of diffuse and spectral reflectivity operative to reflect light received through the associated window into the associated building structure; a second wall extending longitudinally between opposing first and second ends that at least partially define said shelf length and extending laterally between opposing first and second edges that at least partially define said shelf width, said second wall including an inner surface and an outer surface disposed opposite said inner surface, said second wall oriented with respect to said first wall such that said inner surfaces of said first and second walls are facing one another with said first ends disposed adjacent one another forming a first shelf end and said second ends disposed adjacent one another forming a second shelf end, said first and second walls being positioned in spaced relation to one another such that a shelf height is at least partially defined therebetween and such that a shelf chamber is at least partially formed between said inner surfaces of said first and second walls; a first support element received within said shelf chamber and including a first wall portion extending in a heightwise direction between said first and second walls, said first support element oriented in a widthwise direction relative to said first and second walls, and said first support element being disposed along said first shelf end such that a first cavity is formed between said first and second walls along said first shelf end outwardly of said first support element in a lengthwise direction; and, a second support element received within said shelf chamber and including a first wall portion extending in a heightwise direction between said first and second walls, said second support element oriented in a widthwise direction relative to said first and second walls, and said second support element being disposed along said second shelf end such that a second cavity is formed between said first and second walls along said second shelf end outwardly of said second support element in a lengthwise direction; and, an inner-core structure disposed within said shelf chamber between said inner surfaces of said first and second walls, said inner-core structure terminating adjacent at least a portion of said first and second support elements such that said first and second cavities remain at least partially void of said inner-core structure.
