什么是重启时间

重启时间是指灯管(尤其是高强度气体放电灯)在关闭后重新点亮或重启所需的时间。灯管关闭后,需要一定的冷却时间才能重新点亮。在运行过程中,气体放电灯会达到很高的温度和压力,灯具的镇流器需要时间在灯管中产生新的电弧。

重启时间因所使用的具体灯管和镇流器而异。金属卤化物灯是气体放电灯的一种,其重启时间为 15 至 20 分钟。这意味着,这些灯管关闭后,大约需要 15 到 20 分钟才能冷却下来,准备重新点亮。

从 Rayzeek 运动传感器产品组合中获得灵感。

重启时间是照明系统的一个重要考虑因素,尤其是在需要立即或快速重新照明的应用中。在体育场馆等需要关灯再开灯的场合,较长的重启时间可能会造成延误,给观众带来不便。为了解决这个问题,目前有一些技术,例如即时重启系统,可以让灯具在重新开启后几乎立即重新点亮。
