1. Lighting method following which one modulates, thanks to a concentrating-distributing device, a luminous flux which is issued from an intense source of small dimensions in at least one pencil of rays with a small angular opening, which is directed to at least one lighting surface in order to distribute the light, distinguished by the fact that one judiciously directs, with a grazing incidence, each above-mentioned pencil of rays to a series of prismatic refractors arranged in the same way as an optical network on a level with a lighting surface (6) stretching longitudinally with regard to the pencil of rays and on at least one surface which reflects the light and stretches obliquely in relation to the pencil of rays and to the abovementioned optical network. |
