Abstract
The system (100) has a light source (111) propagated in a single diffusion screen (110), where the light source produce luminous rays. An insulating separating film (112) separates the functions for realization of multiple main optical functions through the screen. The screen diffuses a light beam via multiple reduced surface zones having an assembly of micro-asperities or a specific optical surface. The optical surface disperses a part of luminous rays being propagated in the screen towards the outside of the screen. The light source is formed by multiple LEDs of different colors. The main optical functions include functions of stop, lantern, direction indicator, backup light, fog light, side marker, or side repeater.
