Abstract
Patente de Invenção: <B>"MéTODO E DISPOSITIVO PARA CONTROLAR O DESEMPENHO OPERACIONAL DE LâMPADAS DE DESCARGA DE GáS"<D>. Método e dispositivo para controlar o desempenho operacional de pelo menos uma lâmpada de descarga de gás (10). O controle é efetuado com a ajuda de um controlador (1), cujo componente proporcional é estabelecido na dependência de um valor desejado aplicado externamente (SOLL) de um parâmetro operacional da lâmpada de descarga de gás (10), por meio do que para valores desejados de baixo brilho o componente proporcional do controlador (1) é estabelecido alto, e para valores desejados de grande brilho da lâmpada de descarga de gás (10) é estabelecido baixo. Desta maneira é possível acender confiavelmente a lâmpada de descarga de gás (10) mesmo em valores de baixo brilho, sem o aparecimento de um flash de luz, e ao mesmo tempo para evitar instabilidades no caso de valores de alto brilho da lâmpada de descarga de gás (10).
