The Excelitas BUB 0661 U-Shape Flashlamp features a B1 envelope construction with 220 - 500 V anode voltage range and a nominal operating voltage of 400 V. It is capable of 4 Hz flash rate over a service life of 5x10^6 flashes.
FlashTubes是具有高功率密度的光源。因此，它们仅由高温材料制成。所有闪光灯都包括由硬玻璃或石英玻璃制成的管，其中电极（阳极/阴极）在每个端密封。除了线性玻璃管外，还提供各种其他形状，例如U，环和螺旋形。连接闪光灯时，必须观察到极性。 几乎所有闪光灯都配有电容触发电极。例如，在玻璃外侧缠绕在管子，银条或透明导电涂层上的电线。电极上的导线可根据我们的标准或客户规格提供固体或柔性的铅线。某些类型的管也配有底座和保护罩。 Electronics flashtubes are gas discharge devices for pulse operation. Xenon is used as a fill-gas for most applications. The flash duration ranges usually between 10us to 10ms. For stroboscopic and beacon operations, the discharges are produced periodically and often over a longer period of time. In most cases the stroboscopic frequency ranges between 1Hz to several kHz. Higher frequencies require special flashtubes and/or circuitries.
