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 strip of linear lighting with distributed power conversion is disclosed. The linear lighting includes a flexible PCB. The flexible PCB is divided into repeating blocks, which are arranged electrically in parallel with one another between power and ground. Each repeating block includes power conversion and conditioning circuits. A plurality of LED light engines are connected to the outputs of the power conversion and conditioning circuits, electrically in series with one another. The power conversion and conditioning circuits typically include at least a full-bridge rectifier. A pair of conductors run the length of the PCB adjacent to it and are connected to each of the repeating blocks. A flexible, transparent covering surrounds the PCB and pair of conductors.

A method for flashlamp control, in which a main pulse of the lamp current, producing a flash, is generated, and a pre-pulse of the lamp current is previously generated by application of a bias voltage includes a flashlamp with an ignition electrode, a bias voltage source, a main voltage source and a control system. The load of the flashlamp is minimized during the production of a main pulse by a pre-ignition. A pre-pulse is generated by applying a plasma voltage which is higher than the bias voltage, as an electrode voltage, and igniting a plasma in the flashlamp by means of an ignition electrode and maintaining same by means of the bias voltage during the pre-pulse.

A method of operating a flashlamp (2) in a skin treatment system (1) comprises the steps of establishing a conductive path between the flashlamp (2) and a charged capacitor (4) causing a free discharge within the flashlamp, and interrupting said conductive path so as to cut off the current through the lamp when the current density drops below a predetermined current density threshold level (Ix) or when the energy applied to the skin reaches a certain maximum (E.sub.M).
