The lighting system concept is a flexible, modular, ambiance and stylish lighting system that is designed to give commercial interiors a brand new look. The concept is made of dual layer white polycarbonate slanted sheets with an appearance like conventional boat sails. Between these two layers, lights have been inserted and are attached on the inside layer. The upper layer is incised in stripes through which lights glow in a unique manner with great aesthetics. The units can feature different color lights such as green, cyan or magenta, however, intensity of light may vary with different colors. Each unit contains a metal tube base that allows the user to fix it on the wall or roof and gives easy rotation for multi-directional lightings.
