More Information
Summary:An LED module can be powered by two conductors and the LED module includes a constant current driver. The constant current driver is configured to provide a predetermined current so long as the input voltage provided on the two conductors exceeds a predetermined level. The constant current driver powers an LED string supported by the LED module and can adjust the current to the LED string based on an input signal. A conversion circuit converts the input voltage to an input signal and provides that input signal to the constant current driver so that dimming can be provided while only using two conductors to provide power.
