UV LEDs

ILT is pleased to make available developers kits for UV LEDs. These off-the-shelf kits are designed to give researchers and product developers a plug-

and-play solution for proof of concept and design testing. The developer’s kits are packaged for UVA, UVB and UVC applications. Each kit comes with a high-powered LED on a metal core board, mounted to a heat sink. Kits can be bundled with an optional lab power supply that is sold separately. This enables the developer to test a range of drive currents (up to the specified max) yielding a range of optical power. The kit also includes paper disks that fluoresce when placed over the UV LED, enabling users to quickly and safely see if the UV LED is powered on.  

 

As has been seen with LEDs in other industries and applications, UV LEDs open up new possibilities in a multitude of applications for form, fit and function over traditional UV lamp-based light sources. The small form factor, efficiency, narrow spectrum and long life of LEDs allow developers to design solutions that are more compact, robust, reliable, environmentally friendly and optimized for the application, among other positive attributes. But designing around this newer technology poses an equal number of challenges for developers as well.  

 

ILT’s UV LED Developer’s Kits are designed to take the guess work out of the testing process.  Each kit’s LED features a high-powered LED at the most common peak wavelengths, with UVA at 365nm, UVB at 305nm, and UVC at 265nm.  LEDs are mounted on an aluminum heatsink, with 7” leads pre-soldered for connecting to a lab power supply via alligator clips. Connecting the kit to the the optional lab power supply (or your own lab supply) enables developers to test the LED at different power levels by simply dimming down the current.

 

ILT has been designing custom lighting products for over 50 years.  Our team stands ready to assist you  with your UV LED project including expertise in layout and design, electrical requirements, LED procurement, measurement, manufacturing and more.

UVC Kit Application Information

UVC Peak WavelengthUVC light encompasses light in the spectrum between 100 – 280 nanometers (nm). UVC is short wavelength ultraviolet light that is used primarily in germicidal applications such as purification of air, water, and surface disinfection. UVC light is also used in some medical applications including acne treatment and wound care. UVC light is hostile to microorganisms such as bacteria, viruses, molds and other pathogens. Using UVC light in these applications has gained popularity with the increase in chemical-resistant microbes, and harmful by-products that come along with chemical disinfectants.  UVC light is also harmful to humans, plants, animals, and other organisms and materials, so extreme care should be taken when working with UVC light including shielding the eyes and skin, and covering any objects that may react adversely when exposed to UVC.

 

UVC is electromagnetic radiation with a wavelength that is not visible to the human eye. In nature, virtually no UVC light reaches the earth’s surface as all of it is filtered out by the atmosphere. UVC light between 260 – 270 nm is particularly lethal to microorganisms as it deactivates the DNA of bacteria, viruses, and other pathogens that  can cause disease. UVC radiation penetrates the cells of  these microbes, damaging the nucleic acid and rendering them unable to reproduce.  

 

Traditional sources used to emit UVC light include mercury-based lamps, which emit UV light at 253.7 nm, and pulsed xenon lamps that emit light across the entire UV spectrum, with a peak wavelength at approximately 230 nm. UVC LEDs are selectable with peak wavelengths between 255 and 280 nm.  With mercury lamps being the most common UVC source, developers often look for LEDs with an equivalent peak wavelength of 254 nm, however selecting an LED that falls within the target of 260 – 270 nm (and beyond) can also be considered for germicidal applications.

 

Dosing is another critical element in the design of a disinfection system. UV Dose = UV Intensity (I) x Exposure Time (t). UV light intensity is defined as power output generated by the light source in the UVC range and is represented in milliwatts per centimeter squared (mW/cm2). Exposure time (t) is measured in seconds (sec) and dose is typically represented in millijoules per centimeter squared (mJ/cm2).

 

The LED in the ILT kit is designed to give developers flexibility with intensity. We selected a high power LED that when connected to a lab power supply enables it to be dimmed to find the optimal intensity for the application.  ILT develops and sells light meters and spectroradiometers that can measure light across the UV spectrum.  Click to learn more about our light meters and light measurement systems.

UVB Kit Application Information

UVB is medium wavelength ultra violet radiation that encompasses the spectrum of 290 – 320 nm.  Unlike UVC radiation, the earth’s atmosphere does not absorb all UVB light thus allowing some of this radiation to reach earth’s surface.  The primary applications for UVB light are primarily medical, horticultural, and herpetological.  Exposure to UVB light can cause harm, so proper skin and eye protection should be used when working with UVB light.

Light Therapy

Medical uses for UVB light include phototherapy and photodynamic therapy used in the treatment of various skin conditions including eczema, psoriasis, vitilago, wound healing, and some cancer treatments.  The common spectrum of UVB light for this application is 305 - 315 nm.  

Horticultural

In nature plants are exposed to all the light that reaches earth.  With the wide-spread adoptoin of LED lighting that encompasses primarily light from the visible spectrum, supplemental UVB lighting has become a necessary component to for indoor growers.  Plants respond to exposure to both UVA and UVB light.  Different plants respond in different ways, but in general studies have shown increased production of antioxidants / flavonoids and other natural sunscreen compounds in a process called photomorphogenesis.   Studies have shown that the presence of UV light increases THC production in cannabis, and aroma and flavors in herbs.  LEDs are a prime alternative to traditional lamps sources with their targeted spectrum, longer life, and better efficiency.

Herpetological (Reptiles)

Reptiles that are kept indoors require lighting that mimics the sun, including UV light.  This range of the light spectrum is best known for its role in skin synthesis of vitamin D3 among other effects.   For this to occur, light must contain UVB in wavelengths ranging from 290 nanometers to about 315 nanometers. Traditional lamp sources often stop emiting UV light long before they stop emiting visible light, requiring owners and keepers to either meaure the light perodically, or just set a re-lamping schedule that falls well before the expected lamp failure.  LED solutions are a good alternative with the ability to control the light, its more stable and consistent output, and energy efficiency.  

 

Dosing is a critical element in the design of any UV light system.  UV Dose = UV Intensity (I) x Exposure Time (t).  UV light intensity is defined as power output generated by the light source in the UVB range and is represented in milliwatts per centimeter squared (mW/cm2).  Exposure time (t) is measured in seconds (sec) and dose is typically represented in millijoules per centimeter squared (mJ/cm2).

UVA Kit Application Information

UVA is longwave radiation that spans the wavelengths of 315 – 400 nm.  Like UVB light, UVA light is also used in many medical and horticultural applications, often in combination with UVB light.  UVA light is also used in many curing applications.  Exposure to UVA light can cause harm, so proper skin and eye protection should be used when working with UVA light.

UV Curing

Ultraviolet light is used in the curing of inks, adhesives, coatings, paints, epoxies, resins and the like.  Curing with ultraviolet light greatly increases the speed with which the final product is ready for use.  Traditional light sources found in curing systems include mercury vapor lamps and fluorescent lamps.  LED is being widely adopted in curing applications as LEDs offer longer life, more efficient operation, and a targeted spectrum.

 

Dosing is a critical element in the design of any UV light system.  UV Dose = UV Intensity (I) x Exposure Time (t).  UV light intensity is defined as power output generated by the light source in the UVA range and is represented in milliwatts per centimeter squared (mW/cm2).  Exposure time (t) is measured in seconds (sec) and dose is typically represented in millijoules per centimeter squared (mJ/cm2).
