A light signaling device (1) which comprises a tubular body (2) that is extended between a lower edge (3) thereof and an upper edge (4) thereof along a main extension axis (A), and has an outer surface (5) to which LEDs (15) are mechanically connected; it also has an inner surface (6) which defines a channel (7) inside the tubular body (2) and is provided with heat dissipation means (23) through which the heat generated by the LEDs (15) during their functioning is dissipated. The light signaling device (1) also comprises a lower air conveyor (25) which is mechanically connected to the lower edge (3) of the tubular body (2), partially closes the lower opening (8) of the inner channel (7) of the tubular body (2) and is provided with a plurality of separate conveyance channels (26), each of which extended between an inlet section (27) thereof and an outlet section (28) thereof according to a trajectory (B) which has at least one component radial with respect to the main extension axis (A). Each of the conveyance channels (26) is in communication with the light signaling device (1) exterior by means of the inlet section (27) and with the lower opening (8) of the inner channel (7) by means of the outlet section (28). The lower air conveyor (25) is susceptible of forcing, in the inner channel (7) of the tubular body (2) through the conveyance channels (26), an air flow which transversely hits lower air conveyor (25), in order to cool the LEDs (15) via convection. |
