Abstract:
1. A luminous signaling device with a heat dissipation system, comprising: a generally tubular element having a hollow inner cavity and a first slot through said tubular element; an LED emitter operatively connected to said tubular element, said LED emitter being operable to emit light in response to power; an electronic circuit configured to provide power to said LED emitter; at least one wire connecting said circuit and said LED emitter, said at least one wire passing through said first slot into said inner cavity of said tubular element; and wherein said heat dissipation system is configured to provide a natural convection current such that air heated by said LED emitter flows out through said inner cavity, leading cooler air to enter said inner cavity through said first slot.
