Registered Office: Bedford House, 69-79 Fulham High Street, London, SW6 3JW, United Kingdom. UVC LEDs are typically defined as having a wavelength on the electromagnetic spectrum of 200nm to 280nm. Scientists have proved that wavelengths between 280nm and 300nm are germicidal and can be used for disinfection and sterilisation.There is a misconception that 254nm is the optimum wavelength for disinfection because the peak wavelength of a low-pressure mercury lamp (simply determined by the physics of the lamp) is 253.7nm.
A new generation of LEDs now looks set to challenge conventional UV fluorescent sources. If you’re thinking about using UV LEDs in any application, please take advice from someone who is technically competent in the use of this kind of technology.To see other lighting questions answered by experts, click Revo Media Partners is part of the Clarion Events Group of companiesRevo Media Partners Limited is registered in England and Wales, Company Number 07335390. For any given wavelength of germicidal UV light, the power and duration of exposure would need to be calculated in order to achieve the desired level of disinfection.Yes, there are actually six levels of disinfection based on the reduction factor. Klaran UVC LEDs require little power, making them ideal for use in rechargeable, handheld devices.Klaran UVC LEDs are designed to expel heat in the reverse direction, allowing close placement of the LEDs to the target surface for maximum dosage and log reduction values, saving time and money.High intensity devices for on-demand disinfection of water, air, and surfaces.Want to accelerate product innovation and feasibility testing in your organization?

Unfortunately, this means there is rarely comparable information until you have designed and built a UVC LED module and tested it next to a lamp.
What is the ‘germicidal range’ of ultraviolet light? Ultraviolet LED. This allows solutions to be smaller, battery powered, portable and with instant full light output.Low pressure mercury lamps emit an almost monochromatic light with a wavelength of 253.7nm.
Low-pressure mercury lamps (fluorescent tubes) and high-pressure mercury lamps are also used for disinfection and sterilisation. Rs 50/ Piece Get Latest Price. We offer expert assistance to product teams developing and evaluating disinfection solutions.
UVC LEDs can be manufactured to target very specific and narrow wavelengths. However, disinfection and sterilisation occur over a range of wavelengths.Historically, mercury lamps have been the only option for disinfection and sterilisation.

Ultraviolet (UV) light has been used for many years in industry and in health and hygiene regimes. For instance, in water there may be multiple germs with different optimal absorption wavelengths. UV LED DISINFECTION TECHNOLOGY Ultraviolet (UV) disinfection technology has been the star performer in water and air treatment over the past two decades, due in part to its ability to provide treatment without the use of harmful chemicals. As this technology develops, costs will also continue to decrease which will make UVC LED a viable solution for an ever-increasing range of applications. But how well do they actually perform?UVC LEDs are typically defined as having a wavelength on the electromagnetic spectrum of 200nm to 280nm.The germicidal range is known to extend beyond 280nm and is now generally thought to extend to 300nm, although this too may change with more research.
Indeed, these breakthroughs in UV-C-transparent epitaxial stacks entitle, for the first time, the UV-C LED sector to the technology improvement roadmap that performed so well for blue LEDs and transformed the lighting industry. UVC LED technology is still developing, however, which means that more wavelengths will become available and the efficiency of LEDs will increase.
The best reported GaN-based visible-spectrum LEDs exhibit PCEs above 80%. This allows solutions to be tailored to the particular application need.Yes, peak absorption rates do vary from germ to germ, though most are around 265nm.Yes, a single wavelength can be used. Due to their small size, UVC LEDs can be easily integrated into a wide range of products- such as water purification systems, medical devices, air purifiers, and more- to provide effective disinfection.Pioneered by Crystal IS, Klaran LEDs are produced on a proprietary Aluminum Nitride (AlN) substrate delivering performance output that surpasses the effectiveness of other UVC LED sources on the market today.Optimized for peak germicidal eradiation, Klaran UVC LEDs are a formidable defense against the persistent threat of new antibiotic resistant superbugs.Off grid, no problem.

However, when looking at the lamp specifications, this lifetime is only achievable with a limited on/off cycle rate. Due to their small size, UVC LEDs can be easily integrated into a wide range of products- such as water purification systems, medical devices, air purifiers, and more- to provide effective disinfection. UVC LEDs are small devices that emit UVC light to destroy dangerous pathogens in water, surface, and air. A wavelength of 265nm is generally accepted as the optimum as it’s the peak of the DNA absorption curve. UVC LEDs are individual light sources that must be designed into an application to meet the specific requirements. If we start with a population of one million bacteria, one would measure disinfection effectiveness as follows:For further information see the US Environmental Protection Agency’s It’s vitally important that we all remember the serious potential for harm that exists within UV radiation.
