The present disclosure relates to a flash generator for providing power supply to a flash tube so that the flash tube rapidly provides a light output adapted to FP-sync, Flat Peak. The flash generator comprises a capacitor bank, an output and a switch configured to switch a current flow from the capacitor bank via the output to provide a variable power via the output. The flash generator further comprises a controller for controlling the switch, whereby by controlling the on time of the switch, the generator is operative to provide, during a time period of 100 to 2000 μs during a peak time period within the time period, an average power at least 4 times higher than the average power provided during the other time period within the time period, whereby the flash tube during the peak time period becomes fully ignited.

A control circuit and method for a bleeder, a chip, and a driver system. The bleeder control circuit is connected to a dimmer detector used for detecting the presence or absence of a dimmer and a type of the dimmer. The control circuit of the bleeder is used to receive a detection signal outputted by the dimmer detector, and generate a control signal for the bleeder according to the detection signal, the control signal is used to control an operating state of the bleeder. The application correspondingly generates a control signal for a bleeder according to a detection signal indicating the presence or absence of a dimmer and the type of the dimmer so as to control the bleeder to operate only at a given phase interval, and may thereby reduce the power consumption of the bleeder when ensuring the stable operation of a dimmer.

Various embodiments provide a projection arrangement. The projection arrangement may include a discharge lamp; and a ballast for the discharge lamp. The ballast is designed to provide, during operation of the projection arrangement, a lamp current in the form of alternating current and having an average frequency and a preset waveform, which has a preset commutation scheme, to the discharge lamp. The preset commutation scheme is preset by a preset time sequence of commutations of the lamp current. The ballast is designed to provide the lamp current in such a way that the preset commutation scheme of the lamp current is deviated from repeatedly with at least one preset intervening time period by at least one DC phase with a preset time duration.
