Each unit has a housing (11, 12) of a shape adapted to a saw-cut cavity (9) accommodating the unit and lying in a plane P. Each unit is provided with stabilizers (23, 23′; 24, 24′) which are situated at the ends of said emission surface and lie in the plane P as well, thus preventing turning of the unit around an axis A normal to the plane P.
