Mini-optical light shelf daylighting system

A daylighting apparatus, located in a window opening located on a wall of a room, for redirecting daylight incident at said window opening into said room to illuminate said room, comprising:

• at least two panes of glazing oriented in a parallel and spaced apart relationship, for mounting in said window opening;
• a plurality of identical light reflecting element means, mounted in a fixed position, that is a substantially parallel and equally spaced apart relationship, for redirecting said incident daylight into said room, each of said light reflecting element means comprising an elongated substantially linear member having a first edge located to receive said incident daylight and a second edge distal from said first edge, and having a top surface and a bottom surface which include:
• light reflecting means, integral to said top surface and being of a geometry to redirect said incident daylight received from a predetermined range of directions onto a ceiling of said room,
• light shading means, integral to said bottom surface and extending at an acute angle with reference to said top surface from said first edge toward said second edge to a predetermined location, for blocking low altitude components of said incident daylight from entering said room,
• light redirecting means, integral to said bottom surface and extending from an end of said light shading means at said predetermined location toward said second edge, for redirecting incident daylight reflected from an adjacent light reflecting element means onto said ceiling;
• and frame means for mounting said plurality of identical light reflecting element means between two adjacent ones of said at least two panes of glazing.
