Abstract
UN APARATO DE CONTROL DE UNA LAMPARA FLUORESCENTE QUE DETECTA UN ESTADO DE FIN DE SERVICIO DE UNA LAMPARA FLUORESCENTE PARA QUE SEA POSIBLE LLEVAR A CABO UNA CUENTA ATRAS ADECUADA. EN EL APARATO DE CONTROL SE FORMA UN CIRCUITO DE CARGA DE UN CAPACITOR CONECTADO ENTRE LOS FILAMENTOS DE UNA LAMPARA FLUORESCENTE Y UNA BOBINA DE CHOQUE CONECTADA EN SERIE AL FILAMENTO Y HAY UNA BOBINA DE DETECCION PARA DETECTAR UNA CORRIENTE DE TUBO QUE FLUYE A TRAVES DEL CIRCUITO DE CARGA Y UN CIRCUITO DE DETECCION QUE RECIBE UNA TENSION DE SALIDA DE UN CIRCUITO RECTIFICADOR QUE RECTIFICA LA SALDA DE LA BOBINA DE DETECCION PARA DETECTAR UN AUMENTO DE LA TENSION DE SALIDA QUE TIENE LUGAR CUANDO LA FRECUENCIA DE SALIDA DE UN CIRCUITO DE OSCILACION ES MODULADA POR UN CIRCUITO DE MODULACION.
