Abstract:
Es wird ein Blitzgerät, das wenigstens zwei Blitzröhren und wenigstens zwei Energiespeichereinheiten aufweist, dargestellt, wobei jede der wenigstens zwei Energiespeichereinheiten angeordnet ist, um aufgebaut zu sein, so dass dieses einer der wenigstens zwei Blitzröhren für einen Blitz zugeordnet ist. Das Blitzgerät ist aufgebaut, um den Energiebetrag zu steuern, der von den wenigstens zwei Energiespeichereinheiten an deren entsprechende Blitzröhre zugeführt wird, und um die Blitzdauer der entsprechenden Blitzröhre in Abhängigkeit voneinander zu steuern, entsprechend für jede Blitzröhre, um im Wesentlichen die gleiche Farbtemperatur von jeder Blitzröhre für einen Blitz zu erhalten. Ein Verfahren und ein Computerprogramm zur Verwendung in dem Blitzgerät werden auch dargestellt.
Abstract:
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.
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.
