Abstract

Patente de Invenção:<B>"LASTRO ELETRôNICO PARA OPERAR PELO MENOS UMA LâMPADA DE DESCARGA DE GáS" <D>. Método para detectar o efeito de retificação em pelo menos uma lâmpada de descarga de gás (10) e lastro eletrônico para operar pelo menos uma lâmpada de descarga de gás, que reconhece o aparecimento de um efeito de retificação na lâmpada de descarga de gás (10). No sentido de ser capaz de detectar o aparecimento do efeito de retificação na lâmpada de descarga de gás (10) é monitorada simplesmente e com alta sensibilidade a corrente (i~ 1~) fluindo via um enrolamento primário (7A), conectado paralelamente à lâmpada de descarga de gás (10), de um transformador de aquecimento (7A-C) ou um parâmetro (i~ 2~, u~ 3~) dependente desta corrente (i~ 1~), e no evento em que um valor limite predeterminado é superado, é determinada a presença do efeito de retificação na lâmpada de descarga de gás (10).
BRPI9808165-9A 1997-03-04 1998-02-12 método para detectar o efeito de retificação que ocorre em uma lámpada de descarga de gás e lastro eletrÈnico para operar pelo menos um lámpada de descarga de gás. BR9808165B1 (pt)
