灯亮，菌灭：艾迈斯欧司朗智能UV-C LED解决方案功能强大、用途广泛，能够有效地消灭病毒、细菌和芽孢。
UV-C处理：改变卫生行业
你知道吗？紫外线是一种不含化学物质的高效消毒剂。
我们与客户携手合作，共同开发领先的创新技术，提高生活安全性。我们先进的UV-C解决方案，让个人、商业和公共空间的净化工作变得简单易行。微型化解决方案支持在公共和家用电器中将高效的UV-C LED与占位监测器进行集成，可将其与标准光源结合，对公共空间进行消毒，也可放置在净化盒或水龙头中，给手持设备和水龙头消毒。智能空气过滤系统使用我们的光谱传感器来检测空气质量，包括烟雾或有机污染等因素。将我们的UV-C照明和传感元器件结合起来，能够预测过滤器更换时间，例如在使用空调的过程中，可以明确地知道何时真正需要更换过滤器，这样可以节省成本，减轻工作量，毕竟更换过滤器的频率并不影响污染情况。
艾迈斯欧司朗的UV-C LED产品组合可提供不同功率等级的产品，确保最佳使用寿命，提高辐射通量。通过空间优化，UV-C LED支持灵活快速可切换的设计。UV-C LED的消杀功能只在有需要的位置和时间才会开启，即便是在空间极其有限的结构内部也可装配。功能开启后，会即刻产生全剂量辐射，完成空气消杀后也不会生成臭氧。该技术支持脉冲调光，根据有毒有害物质的变化情况来调整所需辐射剂量。
控制辐射的同时确保全面消杀
要想控制辐射的同时确保全面消杀，可使用精密的UV-C传感器来监测剂量。无论光源效能如何变化，都可保障消杀效果。消杀时间和所用剂量也进行了优化，可以防止辐射过量，尽可能减少能源浪费，减缓产品老化速度，并减少暴露材料承受的压力。通过主动跟踪检测UV光源老化情况，可实现状况监测和预测性维护。
在有人区域安装不可见的UV-C时，艾迈斯欧司朗成熟完善的占位监测、篡改/偏差检测或智能门禁解决方案可作为支持性安全措施，实现上层空气、主动光幕或整个房间的净化。
首先，占位监测以1D直接飞行时间(dToF)为基础，经济高效，可扫描室内消杀过程中不应暴露的任何移动或静态物体。如果出现意外占位情况，可以选择性拦截或中断服务。第二，主动检测UV-C光源模块位置和朝向、监测传感器或防护盖的变化。第三，在消杀或设备维护期间，智能生物识别门禁可用于跟踪确保未经培训或授权的人员均不在场。
Clean water, surfaces and air
Imagine a world in which light makes your everyday life healthier, safer and more pleasant. With UV-C solutions powered by ams OSRAM, this vision becomes reality.
Light for making our world healthier and improve human well-being is part of our mission. Today like never before current global developments have raised the attention on topics of sanitization and purification. Be that at work, at home or on the move, people everywhere are confronted with a new reality and awareness for health and safety.
Today UV-C mercury vapor lamps are used to provide clean water, and surfaces. With UV-C LED solutions - their small and robust design, as well as their mercury free nature, we can extend the use of UV-C Radiation to completely new application areas and overcome obstacles which are currently limiting the broad deployment of UV-C radiation.
After years of R&D and various research projects with leading partners in the industry and the scientific world, ams OSRAM offers its UV-C LED products from low to high power.
The OSLON® UV series is designed to provide efficient UV-C radiation for but not limited to home goods and consumer applications. It allows for flexible designs for various types of UV-C applications in the areas of air, water and surface sanitization purification, as well as treatment or sensing. Design possibilities are endless and range from point-of-use water treatment, to air purification in portal devices or air conditioning systems.
What is UV-C radiation
The sun emits optical radiation in form of visible and invisible light. We humans define light as what we can see from the visible spectrum of light, that is, the wavelength between violet (400nm) and dark red (800nm). For the use of light against viruses and germs, the focus is on the range below 400 nanometers, the so-called UV radiation. UV light is divided intro three ranges: UV-A, UV-B and UV-C. The wavelength decreases progressively from 400 to 100 nanometers.
Category A ultraviolet sunlight reaches the earth almost unfiltered. UV-A radiation penetrates deep into our skin and causes it to age. UV-B light reaches our upper skin layers and is responsible for sunburn. The short-wave, particularly high-energy UV-C radiation from the sun, on the other hand, is completely absorbed by or ozone layer. There is therefore no natural UV-C radiation on earth. Life on earth has thus developed without being exposed to UV-C radiation. In other words: There was simply no need to develop natural defense mechanisms against UV-C light. This opens special possibilities for science, medicine and technology.
UV-C photons with a wavelength of 200 to 280 nanometers have sufficient energy to alter microbial DNA meaning the exposure to the electromagnetic radiation modifies the genetic material of microorganisms and disrupts their ability to reproduce. As UV-C radiation attacks the helix structure of DNA and RNA it is also effective to inactivate multi-resistant pathogens.
For the use of light to inactivate pathogens, the focus is on invisible light below 400 nanometers, the so-called UV radiation, in particular the Category C ultraviolet light. Although both UV-B and UV-C can harm cells and hence have the capability for sanitization, the extent of the molecular rearrangement of the DNA / RNA by these two radiations is very dissimilar. The shorter the wavelength as more effectively light can penetrate the cells of Microorganisms, therefore UV-C is more suitable to neutralize pathogens. UV-C radiation triggers a photochemical reaction. Depending on the doses of the absorbed UV-C light it modifies the DNA / RNA helix strands by thymine dimer formation, disrupting the pathogen’s capability to replicate and render it harmless.

Why is UV-C radiation so important
Clean water. Clean air. Clean surfaces. A pure environment where health and safety for everyone is made possible even under the harshest conditions.
In an interconnected world, new challenges arise such as we have recently been witnessing to. We are confronted with pathogens every day. At home and at work, from running an errand, to seeing a physician or the use of plain tab water. The COVID-19 pandemic has led to a heightened sense of awareness for disinfection and with it a desire for effective UV-C solutions. UV-C radiation is able to effectively reduce harmful micro-organisms without the use of chemicals.
Advantages
- UV-C LEDs are environmentally friendly. In comparison to mercury lamps, UV-C LEDs do not contain mercury.
