Abstract: Flash tubes for photographic use, in particular, a flash tube is adapted to provide a light output adapted to FP-sync, Flat Peak. The flash tube includes a length of glass tubing enclosing a gas for use in the flash tube, a cathode inside a first end part of glass tubing and an anode inside a second end part of glass tubing. The cathode includes an element that helps to ionize the gas that is wound around the cathode, such that a spark stream starts from the upper part of the cathode and is prevented from spreading down wards on the cathode and changing the arc length during the light output adapted to FP-sync.

Abstract: A flash generator is capable of identifying which type of flash head and flash head extension cables that is connected to the flash generator. A flash head and flash head extension cable can be identified by the flash generator. The flash generator provides a power supply to a flash head. Further the flash generator includes a first current generator for charging the capacitor. The flash generator further includes a second current generator or a voltage generator connected to an output of the flash generator and arranged to provide a current or a voltage to create a voltage UID over a component in a flash head or a flash head extension cable connected to the flash generator. Processing means are arranged to identify the flash head or the flash head extension cable by the measured voltage UID.

Abstract: A generator for a flash device includes at least a first capacitor bank, which includes at least one capacitor of a first type and at least a second capacitor bank, which includes at least one capacitor of a second type. The first capacitor bank is connectable to a charger via a first switch and the second capacitor bank is connectable to a charger via a second switch. The generator is configured to individually control the first switch and the second switch so that the first capacitor bank and the second capacitor bank can be individually charged to the same or different voltages. Since the first capacitor bank and the second capacitor bank can be simultaneously discharged, it is possible to achieve a desired energy level and color temperature from a flash device connected to the generator.

Abstract: A generator for a flash device includes a first capacitor bank with at least one capacitor of a first type. The first capacitor bank is connectable to a charger via a first switch, and connected to an output via a first component which only allows current flow from the first capacitor bank to the output. A second capacitor bank includes at least one capacitor of a second type connectable to the charger via a second switch, and connected to the output via a second component which only allows current flow from the second capacitor bank to the output. The generator individually controls the first and second switches so that each of the first and second capacitor banks can be individually charged to the same or different voltages. A flash trigger switch is connected to a trigger output for providing a trigger voltage to a flash device connectable to the generator.
