13. A lighting apparatus comprising:
-
a lighting assembly comprising; a first light unit configured to operate at a first duty cycle, and a second light unit configured to operate at a second duty cycle, wherein the second duty cycle is less than the first duty cycle, and the first and second light units emit light having a same wavelength; a current driver unit electrically coupled to the first and second light units and configured to provide driving currents to the first and second light units; a sensor unit optically coupled to the first and second light units and configured to sense light emitted from the first light unit and light emitted from the second light unit so as to determine corresponding first and second intensity values; and a controller unit communicatively coupled to the sensor unit and the current driver unit, and configured to receive the first and second intensity values from the sensor unit and determine magnitudes of the driving current provided by the current driver unit to the first and second light units based on the received first and second intensity values. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
