Abstract

Se describe circuitería electrónica para la mezcla de colores en un accesorio de luz LED mediante atenuación de energía de AC para lograr una temperatura de color ajustable. De acuerdo a una modalidad, un accesorio de luz LED atenuable tiene una primera, segunda y tercera fuentes de luz LED, la primera y segunda fuentes de lux LED que producen luz blanca, la tercera fuente de luz LED que produce luz de color, el excitador de LED configurado para energizar a las fuente de luz LED proporcionando un fuente de corriente de DC variable de un solo canal que tiene dos terminales e salida, y un regulador de corriente para mantener la corriente en la trayectoria de la tercera fuente de luz LED sustancialmente constante puesto que la corriente de salida del excitador LED disminuye cuando la energía de AC se reduce mediante el modulo atenuador, de este modo cambiando el color de la luz producida por la combinación de las fuentes de luz LED.
