Abstract
A luminous signaling device with a heat dissipation system is provided. The heat dissipation system is configured to set up a natural convection current flow to remove air heated by the LED emitter and enable cooler ambient air to flow towards the LED emitter. The signaling device includes a generally tubular element having a hollow inner cavity and a first slot through the tubular element. An LED emitter is operatively connected to the tubular element, with the LED emitter being operable to emit light in response to power. The signaling device includes an electronic driver circuit configured to provide an adjustable current to the LED emitter. Wires connecting the circuit and the LED emitter run through the first slot and the inner cavity of the tubular element.
