A lighting module includes a semiconductor laser element configured for emitting a laser beam in an emission cone, a light-emitting element, and a reflecting surface, a main portion of which reflects light coming from the light-emitting element in order to form an outgoing light beam. A secondary guiding face reflects the light coming from the first emission cone into a measurement cone. Also included is a device for detecting incident light exceeding a predetermined threshold of light intensity which is arranged within the measurement cone. The optical structure of the guiding face causes a spreading of the light so that the measurement cone exhibits an aperture angle greater than that of the first emission cone.
