<p>The guide has a face opposed to a light beam face exit and including prisms following one another according to a longitudinal direction (7) of the guide. The face is arranged to reflect rays of luminous flows towards the exit face. One of the prisms is a complex prism (11), which includes a side (12) configured to reflect rays of one of the flows towards the exit face, and another side (13) including two sections (14, 15). One of the sections reflects rays towards the exit face, and another section deviates the rays towards interior of the guide.</p> |
