Abstract: Assembling unit for use inside housings of luminous signallers arranged in airport areas, comprising an electronic board (1) and at least an electronic or electro-mechanical switching component (4), which is connected to the electronic board (1) by means of electric connecting cables (10), which are flexible for damping mechanical vibrations directed towards the electronic switching component (4) in order to avoid the occurring of undesired switching. According to an aspect of the invention, the switching component (4) can comprise outside a protective material absorbing the impacts or a protective cap (5) or it can be immersed in a liquid which damps its oscillations originating as a consequence of the mechanical vibrations which reach the switching component (4) itself.

Abstract: A current regulation unit in a circuit composed of light sources, connected in series, interposed between an electric source (SE) and the series connection electric circuit (E) of the light sources (SI1, SI2, SIJ, SIN), includes: at least one conversion apparatus (AC1 AC2) for generating an alternating voltage, having pre-settable characteristics; a transformer (T), connected in cascade to the conversion apparatus (AC1, AC2) and connected to the electric circuit (E); and an electric control unit (CE), connected to the conversion apparatus (AC1, AC2) for controlling the modulation of the alternating voltage supplied by the conversion apparatus, in order to obtain a current (z) circulating in the electric circuit (E) having pre-settable electric characteristics. The conversion apparatus (AC1, AC2) is mounted on a printed board (SC1, SC2), removable from a corresponding slot (SL1, SL2), made in the regulation unit (UR).

Abstract: A device for supplying and controlling a light source in a half-dipped signaling lamp includes at least one light source (3), housed in a base support, and a cap (4), removably fastened to the support base. At least one window seat (5a, 5b) is made in the cap and an optical prism (6a, 6b) is associated to the window seat. Reflecting means (7) direct a light beam emitted by the light source (3) toward the optical prism (6a, 6b) while sensor means (21) detect the intensity of the light radiation emitted by the light source (3) or of a representative quantity of the light radiation. A supply and control central unit (CC) receives the signals (S1, S2), coming from the sensor means (21) and supplies the light source (3).

Abstract: A method for detecting and locating a ground failure in an electrical line, of the type comprising a plurality of electrical loads connected to an electrical line (L) and supplied by a supply and control apparatus (1), each electrical load consisting of a load element and an auxiliary device, electrically connected to each other, with said method providing for: the transmission, over the electrical line (L), of at least a first control signal ((S(i,i+1))) from a first auxiliary device (Di), associated to a corresponding first load (Ci) belonging to the plurality of electrical loads, to a second auxiliary device ((Di+1)), associated to a corresponding second load ((Ci+1)), adjacent the first load (Ci), belonging to the plurality of electrical loads; the reception of the first control signal ((S(i,i+1))), transmitted by the first auxiliary device (Di), by the second auxiliary device ((Di+1)); the transmission of a first information signal (Inf(i+1,i)) to the supply and control apparatus (1) by the second auxili
