Patent ID: 8403537

Claim:
A lighting apparatus comprising: at least one pair of flat sidewalls positioned opposing to each other; a reflector body positioned substantially between the pair of sidewalls, the reflector body having an internal light reflective surface including an upper section, a rear section and a front section; the upper section formed with at least one pair of flat sheets facing downwards positioned at the top of the reflector body, whereby the flat sheets of the upper section form an upper angle between them ranging from about one hundred and ten degrees (110°) to about one hundred and eighty degrees (180°); the rear section formed with at least one pair of flat sheets facing frontwards positioned substantially under the upper section, whereby the flat sheets of the rear section form an external angle between them ranging from about one hundred and ten degrees (110°) to about one hundred and eighty degrees (180°), wherein each of the flat sheets of the rear section and a respective adjacent flat sheet of the upper section form an internal angle between them ranging from about ninety degrees (90°) to about one hundred and fifty degrees (150°); the front section formed with at least one pair of flat sheets facing rearwards positioned substantially under the upper section, wherein the flat sheets of the front section form an internal angle between them ranging from about one hundred and ten degrees (110°) to about one hundred and eighty degrees (180°), wherein each of the flat sheets of the front section and a respective adjacent flat sheet of the upper section form an internal angle between them from about ninety degrees (90°) to about one hundred and fifty degrees (150°); and at least one light source positioned on or substantially close to each sidewall, wherein a portion of light emitted by the light source is cutoff upwardly by at least one flat sheet of the upper section and is reflected downwards so as to increase light level on the illuminated area and wherein a portion of light emitted by said light source is cutoff laterally by at least one of: (1) at least one flat sheet of the rear section and (2) at least one flat sheet of the front section and is reflected so as to increase light level on the illuminated area.
