Abstract

Semaforo (1) in cui un involucro esterno (3) contiene tre sorgenti luminose (7a, 7b, 7c) ciascuna delle quali comprende una pluralità di diodi LED (10) disposti su un circuito stampato circolare (12) alloggiato all'interno di una cavità (6a, 6b, 6c) dell'involucro (3). I diodi LED (10) sono alimentati da un alimentatore (15), a corrente costante, che è collegato in ingresso con una centrale semaforica, ed alimenta a bassa tensione i diodi LED (10).(Figura 1).
