Abstract:
The optical system comprises at least one pair of adjacent light-guides (1a, 1b) of a longitudinal shape the surface of which comprises a shell (8) that connects two ends (6) of a light-guide (1a, 1b), and at least one pair of light sources (3), associated with the ends (6) of the light guides (1a, 1b) at the same side of the light guides (1a, 1b), to emit light rays (10) and to ensure their propagation in the direction from the end (6) of the light-guide (1a, 1b) further into the light-guide (1a, 1b) body. Either of the pair of the light-guides (1a, 1b) is equipped in its rear part with optical elements (2) to reflect light rays (10) to its longitudinal exit surface (7a) located on the shell (8) for their exit from the light-guide (1a,1b). The light-guides (1a, 1b) of the said pair of adjacent light-guides (1a, 1b) are located with respect to each other in such a way that in the exit direction of the light rays (10) from the exit surface (7a) one of the light-guides (1a, 1b) acts as the front one (1a) and the other as the rear one (1b) while the rays (10) exiting the rear light-guide (1b) enter the front light-guide (1a) through its shell (8) and exit the front light-guide (1a) via its longitudinal supplementary exit surface (7b) that creates, together with the exit surface (7a) of the front light-guide (1a), the complete exit surface (7). The light sources (3) of the pair of the light-guides (1a, 1b) are time-controlled in such a way that the required dynamic light display is achieved on the complete exit surface (7).
