An ultra-high-performance lamp, often known by the Philips trademark UHP, is a high-pressure mercury arc lamp. [1] These were originally known as ultra-high-pressure lamps , [ 2 ] [ 3 ] because the internal pressure can rise to as much as 200 atmospheres when the lamp reaches its operating temperature.

uhp是飞利浦公司发明的一种专利技术，当灯泡衰竭时会即刻熄灭。 与 UHE灯泡 相比，不仅在相同功耗下，UHP灯泡能产生大光量，并能有效地抑制闪烁情况的发生，而且外形更小巧，亮度衰减更小，寿命更长。

At the heart of almost every projector is a special component: a UHP lamp invented by Philips. These ultra-high-performance lamps are the reason you’ve been amazed by crystal-clear images that jump off the screen. By incredible colors and crisp contrast. And by the outstanding brightness you’ve enjoyed for as long as you can remember.

The UHP lamp (ultra high pressure lamp, usually mercury arc) refers to projector lamps with an internal pressure of over 3000 lbs per square inch. The acronym also stands for ultra high performance.

超高压汞灯（UHP）指汞蒸气压力为10133～20265KPa (100～200atm)，主要发射波长在546.1nm (130atm)，相当的能量为219kJ/mol (52.3kcal/mol)的汞蒸气弧光灯。 超高压汞灯的 光亮度 较大可作为 点光源 使用，应用在 探照灯 方面。 另外超高压汞灯的寿命一般较 高压汞灯 的使用寿命低。 用于产生液晶 投影器 的光源，原灯管通过电压后，极间距间产生高电位差的同时产生高热，将汞汽化，汞蒸气在高电位差下，受激发而 放电，内部的卤素元素，就有催化及保护的功用；其 …
