AN3691_20051009, General Lighting Demonstrator Description Application Note

AN3691_20051009, Application note gives a basic description for the AS3691 General Lighting Demonstrator. The Demonstrator offers three modes: Color game mode, In this mode the PWM from the red, green and blue LED strings are changed periodically. With the PWM change the color is changed on the diffuser which allows seeing the smooth color change in combination with the AS3691. RGB Color Sensor mode, in this mode a Hamamatsu RGB sensor is used to detect the RGB spectrum from the ambient light. Together with the AS3681 Demonstrator FUN Led the color can be directly transferred to the AS3691 general lighting demonstrator (Chameleon mode). Manual RGB mode, in this mode each PWM can be adjusted through switch SW1- SW6 in 1/512 PWM steps
