Abstract

Ad un involucro alloggiante una microlampada, fissato all'interno di un serbatoio, è associata un'appendice in materiale plastico trasparente affacciantesi alla lampada mediante una superficie di connessione e presentante almeno una superficie di deviazione ottica allineata secondo una determinata geometria ad una superficie terminale, affacciantesi all'estero del serbatoio. Su azione della superficie di deviazione ottica, la luce emessa dalla microlampada viene riflessa verso una superficie terminale e, viceversa, rifratta all'esterno dell'appendice a seconda del fatto che l'appendice stessa risulti al di sopra e rispettivamente al di sotto del livello di liquido contenuto nel serbatoio.
