和世界地球日上周,我决定撰写本周的博客,了解如何以新技术的方式以一种基本的方式来改善人们的生活。联合国认识到干净的饮用水是一个全球问题,6.6亿人缺乏访问权限。使水清洁细菌和病毒的一种方法是通过破坏微生物的DNA的一定频率发光紫外线(UV)。但是,以前的紫外线光源是基于汞灯的光源,需要大量能量才能起作用并构成汞污染的威胁。
如今,紫外线源可以是发光二极管(LED)的形式。紫外线LED比传统的紫外线光源具有多个优势。它们以低直流功率运行,这意味着它们可以从太阳能源中供电。Combined with the fact that they are lighter and more robust than the traditional sources, this makes them ideally suited for use in remote, off grid locations where clean water supplies are limited or none existent UV LED’s are also tuned to the optimum wavelength for the removal of bacteria, making them significantly more effective in purifying water than traditional light sources. Lastly, UV LED’s do not contain mercury. Consequently there is a significant reduction in the environmental impact risk, through both accidental contamination and the need for recycling when comparing UV LED’s and traditional UV lamps.
从一开始,等离子体技术就一直是LED行业的主要组成部分,提供了先进的血浆蚀刻和制造工具。现在我们的系统被用来促进紫外线的引入,并用于净水系统中,将安全的饮用水带到偏远的地方。
