什么是汞蒸汽灯

汞蒸气灯是一种气体放电灯,其工作原理是通过气化汞中的电流产生光。这种灯由两个钨合金电极组成,放置在含有汞蒸气和氩气的介质中。这个装置被封闭在一个由二氧化硅制成的椭圆形玻璃管中。

当灯泡通电时,高压会启动灯泡并发光。灯泡中的氖气在加热过程中会从粉红色变为橙色。点火器由双金属条和电容器组成,提供高启动电压。当双金属带因加热而膨胀时,它就会短路并打开灯泡。反之,当双金属条冷却时,它就会断开连接并关闭灯泡。

汞蒸气灯具有多种优势,包括每瓦 35 到 65 流明的能效和 24,000 小时的超长额定寿命。它们提供高强度白光,有各种颜色、形状、尺寸和等级可供选择。不过,也有一些缺点需要考虑。这些灯具有 流明维持能力差完全预热需要 5 至 7 分钟,冷却需要 5 至 6 分钟。此外,它们对电压波动也很敏感。
