    • A driver (110; 210) for driving a gas discharge lamp (1) comprises an inductive ballast (14) implemented as auto-transformer having a central tap (15), connected between one output terminal (18) and one input terminal (11), and a triac (130) connected between a second output terminal (19) and a second input terminal (12). Said central tap of the ballast is connected, via a capacitor (150), to said second output terminal (19). A control unit (220) has a sense input (226) for sensing the phase of an input voltage (V IN ) at said one input terminal (11), and is adapted to trigger the triac (130) at a predetermined phase (φ P ) after a zero-crossing of said input voltage (V IN ), said predetermined phase (φ P ) being in the range of Δφ+10° to Δφ+15°, Δφ being the nominal phase lag of the lamp current (I L ) with respect to the input voltage (V IN ).

    • A wake-up lighting device is described, comprising a gas discharge lamp (10) and a lamp driver (1; 2) comprising a power source (100) capable of generating spaced-apart current bursts (51) of alternating lamp current (I). The wake-up lighting device is capable of operating in an off-mode in which no lamp current is generated, and is adapted to switch from its off-mode to a wake-up mode in which the power source (100) operates to: -initially generate an alternating lamp current (I) with a minimum duty cycle value (ΔT) and a reduced current amplitude (IR) close to zero; -subsequently gradually increase the current amplitude while keeping the duty cycle (Δ) constant at the minimum duty cycle value (ΔT), until the current amplitude reaches a nominal current amplitude (IM); -subsequently gradually increase the duty cycle (Δ) while keeping the current amplitude constant at the nominal current amplitude (IM).
