  • Setting Current Error Reduction For Light-Emitting Diode Driver Circuits
    Publication number: 20200022233
    Abstract: A light fixture can include a lighting circuit comprising at least one light source and at least one discrete component. The light fixture can also include a power supply coupled to the lighting circuit, where the power supply provides a setting current to the at least one light source. The light fixture can further include a sensor that measures the setting current flowing to the at least one light source. The light fixture can also include a controller coupled to the power supply and the sensor, where the controller provides, in real time, a setting current correction signal to the power supply to adjust the setting current delivered to the at least one light source. The setting current correction signal can be calibrated to an actual value of the at least one discrete component of the lighting circuit.
