Patent ID: 8766815

Claim:
Light signaling device comprising: a tubular body ( 2 ) which has a lower edge ( 3 ) and an upper edge ( 4 ) and is extended between said lower edge ( 3 ) and said upper edge ( 4 ) along a main extension axis (A); said tubular body ( 2 ) also has an outer surface ( 5 ) and an inner surface ( 6 ) which defines an inner channel ( 7 ) inside said tubular body ( 2 ); said inner channel ( 7 ) has a lower opening ( 8 ) arranged at said lower edge ( 3 ), and an upper opening ( 9 ) arranged at said upper edge ( 4 ); LEDs ( 15 ) mechanically connected to the outer surface ( 5 ) of said tubular body ( 2 ), said LEDs ( 15 ) dissipating heat via conduction through said tubular body ( 2 ); a lower air conveyor ( 25 ) which is mechanically connected to the lower edge ( 3 ) of said tubular body ( 2 ), partially closes the lower opening ( 8 ) of the inner channel ( 7 ) of said 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 said main extension axis (A), each of said separate conveyance channels ( 26 ) being in communication with the exterior of said light signaling device by means of said inlet section ( 27 ) and each of said separate conveyance channels ( 26 ) being in communication with the lower opening ( 8 ) of said inner channel ( 7 ) by means of said outlet section ( 28 ), said lower air conveyor ( 25 ) forcing in the inner channel ( 7 ) of said tubular body ( 2 ), through said separate conveyance channels ( 26 ), an air flow that hits said lower air conveyor ( 25 ) transversely with respect to the main extension axis (A) of said tubular body ( 2 ), in order to cool said LEDs ( 15 ) via convection.
