    摘要: A driver (32) for a solid state lamp (31) receives phase-cut AV supply voltage (PCACV). The lamp is operated at a dimmed light output (LA) on the basis of the phase angle (φ) of the phase-cut AV supply voltage (PCACV). The driver comprises a memory (39) containing information defining a function (F). In a normal mode, the driver monitors the supply voltage and calculates the momentary value of the dim factor (β) from the momentary value of the phase angle (φ) according to a formula β=F(φ). In a learning mode, the driver detects the lowest value (φMIN) and the highest value (φMAx) assumed by the phase angle (φ), and updates the said information in said memory (39) such that the dim factor will have its minimum value and maximum value (βMIN, βMAx) corresponding to the minimum value and maximum value (φMiN, φMAX) of the phase angle (φ), respectively.
