to the rotation of the angular member 19 around the shaft 20 a the angular member 19 thus makes the second arm 12 translate into an extreme low position without any modification of the position of the first arm 11 this rotation enables the system 5 to be positioned at an elevation angle of around 60 u00b0 once again the system 5 can be oriented in any intermediate position the light turret according to the invention can be seen to take the active system from a retracted position into a deployed position thanks to the organ 25 and furthermore it enables the elevation of the system to be set using the handwheel 23 at an angular range of between u2212 5 u00b0 and 60 u00b0 with an azimuth of 360 u00b0 the elevation setting may be made from any azimuth position of the system by means of simple manual maneuvering of the handwheel 23 thus by adding the angular member 19 to the second arm 12 the orientation in elevation is ensured whilst maintaining the compactness of the assembly in order to house it in the caisson 4 the manual controls 23 and 25 of the active system 5 mean that no means requiring the use of electrical energy are necessary thereby making the turret available whatever the circumstances fig5 shows a view allowing the interior of the caisson 4 to be.
