Abstract

UNA LAMPARA DE DESCARGA FLUORESCENTE 1 TIENE DOS ELECTRODOS MODO LUMINISCENTES 15 Y 16 BOBINADOS ALRDEDOR EN FORMA HELICOIDAL. UN CIRCUITO 21 CONDUCE LOS ELECTRODOS PRINCIPALES 10 Y 11 A LOS EXTREMOS OPUESTOS DE LA LAMPARA A NIVELES ALTO DE BRILLO. OTRO CIRCUITO 22 CONDUCE LOS ELECTRODOS MODO LUMINISCENTE 15 Y 16 A NIVELES MAS BAJO DE BRILLO, SOBRE 10MHZ. A NIVELES INTERMEDIOS DE BRILLO, AMBOS ELECTRODOS PRINCIPALES 10 Y 11 Y LOS ELECTRODOS MODO LUMINISCENTES 15 Y 16 SON CONDUCIDOS, LOS DOS CONJUNTOS DE ELECTRODOS SON CONDUCIDOS PARA PERIODOS ALTERNATIVOS DE ENCENDIDO Y DE APAGADO CON LOS ELECTRODOS EN MODO LUMINISCENTE ESTANDO ENCENDIDOS CUANDO LOS ELECTRODOS PRINCIPALES ESTAN APAGADOS Y LOS ELECTRODOS PRINCIPALES ESTAN APAGADOS CUANDO LOS ELECTRODOS PRINCIPALES ESTAN ENCENDIDOS.
