#99193 - the constant current circuit can not be Responding to: ???'s previous message |
the current regulation input, does it specifically require a resistor or a current source would do?
the constant current circuit can not be dynamically controlled, the dynamic current control is by pulses. To obtain "perfect white" there will be separate resistors for R, G and B constant current so that identical control of the 3 colors will produce white regardless of what currents the LED require for the 3 to obtain balance. To avoid confusion: the "constant" current is not "constant" ... how do I say this ... it refer to a constant current circuit that is on/off controlled by pulse. Erik |
