Constant light output circuit and electrical components based thereon

   
   

A method and apparatus for controlling the operation of a gas discharge including regulation of power provided to the lamp for maintaining constant light output throughout the lamp's life. A circuit is provided that continuously monitors the lamp voltage and current. A lamp resistance is determined by dividing the lamp voltage with the lamp current. Based on the lamp resistance, the power provided to the lamp is adjusted to maintain constant light output from the lamp.

Un método y un aparato para controlar la operación de una descarga del gas incluyendo la regulación de la energía proporcionaron a la lámpara para mantener salida ligera constante a través de la vida de la lámpara. Un circuito es a condición de que supervisa continuamente el voltaje y la corriente de la lámpara. Una resistencia de la lámpara es determinada dividiendo el voltaje de la lámpara con la corriente de la lámpara. De acuerdo con la resistencia de la lámpara, la energía proporcionada a la lámpara se ajusta para mantener salida ligera constante de la lámpara.
