The rays emitted by the diode are inscribed in a cone having as axis this global emission axis. As can be seen here, the rays closest to this axis reach the optical lens 18b. The more distant rays enter the optical collimator 17 by walls coming down from the lens towards the diode 8b. They then propagate in the collimator to get out of it by the periphery of the collimator. In this example, this periphery corresponds to the steps around the lens. The surfaces of these steps may, as in this figure, include blows to increase the diffusion of rays coming out of the collimator.
