Abstract
"PROCESSO, E DISPOSITIVO, PARA OPERAR LASTROS ELETRôNICOS PARA LâMPADAS DE DESCARGA DE ALTA INTENSIDADE (HID)" A invenção provê um processo para operar lastros eletrônicos para lâmpadas de descarga de alta intensidade (HID), os lastros eletrônicos tendo um excitador, dois comutadores de força, conectados em disposição de meia-ponte, um circuito em série LC, um controlador excitador para controlar a operação do excitador, um sensor de corrente no circuito da lâmpada, e um sensor de potência no circuito de comutação de potência, o processo incluindo (a) gerar pulsos de frequência f ~ 1~ durante uma duração de tempo t~ 1~ sendo igual a n/f ~ 1~, em que n é um número positivo, e f ~ 1~ é igual à frequência de ressonância do circuito de série LC do lastro; (b) monitorar a existência de corrente no circuito da lâmpada após a duração de tempo t~ 1~ ter decorrido, e no evento em que não se tem corrente no circuito da lâmpada, prosseguindo até etapa (h) ; (c) monitorar a corrente no circuito da lâmpada, e prosseguindo até etapa (h) quando da determinação que a corrente no circuito de lâmpada cessou de fluir; (d) continuar a geração de referidos pulsos de frequência f ~ 1~ durante uma duração de tempo pré- determinada t~ 2~, contando desde o início da geração de referidos pulsos de acordo com a etapa (a) ; (e) comutar a frequência f ~ 1~ de referidos pulsos para uma frequência de operação f ~ 2~, em que uma potência fixada para a lâmpada é alcançada; (f) monitorar a potência na lâmpada e estabilizar esta potência no nível da potência fixada para a lâmpada, por modificação gradual da frequência f ~ 2~, e prosseguindo até etapa (h) no evento que a potência no circuito da lâmpada excede a potência fixada para a lâmpada por uma dada margem; (g) monitorar a corrente em, e potência do circuito da lâmpada de acordo com as etapas (c) e (f) ; (h) inibir a geração de pulsos durante uma duração de tempo pré-determinada aproximadamente igual a t~ 2~/k, onde k é um número positivo; (i) prosseguir até etapa (a) até a duração de tempo pré-determinada t~ 2~, contada a partir do início da geração de pulsos de acordo com a etapa (a), ter decorrido; e (j) inibir a geração de referidos pulsos até a potência para o lastro ser primeiro desligada e então ligada. A invenção também provê um dispositivo para operar lastros eletrônicos para lâmpadas de descarga de alta intensidade (HID).
