UV-C治療
ライトを点けると、細菌が消える。ams OSRAMのスマートなUV-C殺菌用LEDソリューションの力と汎用性で、ウイルス、細菌、芽胞を効率的に撃退できます。
UV-C治療:衛生の革新的技術
紫外線は化学薬品を使用しない優れた除菌剤であることをご存じですか?
私たちはお客様とともに、生活をより安全なものにする先駆的なイノベーションを開発しています。私たちの高度なUV-Cソリューションは、プライベート、ビジネス、公共スペースにおいて、浄化を簡単かつ身近なものにします。小型化により、高効率のUV-C LEDと存在検知装置を公共の機器や家電機器に組み込むことができます。標準的な光源に組み込むことで公共スペースを殺菌したり、浄化ボックスに組み込むことで携帯機器を浄化したり、あるいは水栓に組み込んで水を浄化したりすることができます。インテリジェントなアフィルターシステムは、当社のスペクトルセンサを使用して、空気の品質を判断し、煙や有機汚染を検出します。当社のUV-C照明およびセンシングコンポーネントと組み合わせることで、フィルター交換の予知保全ソリューションのシステムも実現できます。例えばエアコンでは、汚染は交換間隔の問題ではないため、本当に必要なときだけフィルターを交換することでコストと労力を節約することができます。
ams OSRAMのUV-C LEDポートフォリオでは、さまざまな電力クラスでクラス最高の寿命を備えたスケーラブルな放射束オプションが用意されています。これは、スペースに最適な統合により、UV-C LEDの柔軟で迅速なスイッチング設計をサポートできるため、スペースが極端に制限された構造内部でも、意図した場所とタイミングでのみUV-Cを照射させるという利点を提供します。また、電源投入後すぐに完全照射が可能で、処理後の空気中にオゾンを発生させることもありません。この技術は、病原菌の減少率を細かく調整するために必要な線量に調整するパルス調光に対応しています。
UV-Cセンサで照射をコントロールし、治療を成功へと導く
照射をコントロールし、治療を成功へと導くために、精密なUV-Cセンサを使用して用量を監視することができます。これにより、例えば塵や埃などで光源の効率が変化しても、時間や照射量を最適化することで、より効率的な治療プロセスを確約します。過剰な照射を防ぐことで、エネルギーの浪費、劣化の促進、露出した材料への高いストレスを最小限に抑えることができます。UV光源の経年劣化を積極的に追跡することで、状態の監視と予知保全を実現します。
上層空気、アクティブカーテン、またはフルルームのUV-C浄化など、人がアクセスできるエリアに目に見えないUV-Cを導入する場合、安全対策のサポートとして、ams OSRAMの存在検知、干渉/ずれ検知、さらにはスマートなアクセス管理などの確立されたソリューションを活用することができます。
第一に、コスト効率の高い1Dダイレクトタイムオブフライト(dToF)をベースとした存在検知により、治療中に室内に存在すべきでない移動体や静止体をアクティブにスキャンすることができます。これにより、意図しない存在があった場合、選択的な遮断やサービスの中断が可能になります。第二に、UV-C光源モジュール、モニタリングセンサ、または保護カバーの位置や向きの変化を能動的に検出することができます。第三に、スマートなバイオメトリックアクセス管理により、治療中や機器のメンテナンス中に、訓練を受けた正規の担当者以外の人が室内にいないか追跡することができます。
ご注意ください:UV-C LEDテクノロジーの有効性は、最終用途における具体的な実装条件に大きく影響されます。UV-C LEDテクノロジーを基盤としたデバイスは、動作モードに応じて、人の目や皮膚に有害な高濃度の可視光および非可視光を放出します。これらのデバイスを組み込んだ製品は、適用される安全規制を遵守する必要があります。
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.
