ABSTRACT:
A luminaire providing indirect light from a tubular lamp-fixture assembly (55) which is mounted on a wall (65) and covered by a shield (25) which reflects light (3,4,7) upwardly toward a spreader (15) which substantially spreads light (2-7) out from a square corner and broadly over a ceiling (75) mounted under. The spreader and the shield both have quarter-cylindrically-shaped middle portions (10,20) over most of their lengths. The spreader has quarter-trumpet-shaped end-portions (14,16). The shield has quarter-bowl-shaped end-portions (24,26). The combination of the shield and the spreader also disperses light (8,9) substantially away from the sides of the luminaire. Both the shield and the spreader are made light-weight, flexible, and durable. A bracket (83) supports the shield away from the wall (65) mounted over, allowing an accenting strip of light (1) to surround the sides and lower edge of the shield. An adjustable bracket assembly (33,43,130) permits the parallel alignment of the shield with the wall.
