Abstract

Un conector para lámpara de vapor metálico a alta presión de un tipo que incluye sodio en una envoltura provista de electrodos separados y previstos para producir a una potencia de alimentación nominal una presión de vapor de sodio que produce la auto-inversión y el ensanchamiento de las líneas de resonancia D del sodio, y un dispositivo conectado con el conector para energizar la lámpara, que incluye un generador de impulsos eléctricos conectado a dichos electrodos, produciendo dicho generador aproximadamente dicha potencia de alimentación nominal, teniendo dichos impulsos una amplitud que aumenta a una velocidad suficiente y una duración suficientemente corta para producir, además de la luz resultante de la auto-inversión y del ensanchamiento de las líneas de sodio D, una cantidad de luz sustancial en el lado azul-verde del espectro, lo que da lugar a un incremento de la temperatura de color.
