This application relates to the field of semiconductor lighting driving control technology, and discloses a method for compensating for the luminous stability of a copper wire lamp under low-temperature conditions. This method injects a diagnostic current into the copper wire lamp during the turn-off time slot of a single-cycle driving sequence to obtain the transient voltage decay sequence of the light-emitting device.
