Customized UV-LEDs: development and production of application-specific systems
Opsytec develops and manufactures customer-specific UV LED systems wherever standard emitters do not fit – for example with limited space, irradiation from several directions, ring lights, or when the waste heat cannot be released into the surroundings. The wavelengths 275, 365, 385, 395 and 405 nm are available, further wavelengths on request. Development, production and the calibration laboratory are all in-house, so small batches, test samples and prototypes are equally possible.
Possible reasons for customized UV-LED:
- The system already exists. Standard products can’t be installed due to limited space.
- Irradiation from one direction is not sufficient
- The determination of irradiation wavelength has not yet taken place
- You are looking for a competent and independent partner
Your advantages with Opsytec UV-LED customized solution:
- Development and production from a single source
- Ideal for small batches, tests and prototypes
- Wavelength 275 nm, 365 nm, 385 nm, 395 nm and 405 nm available
- Further wavelengths are possible
- Suitable sensor? We offer customer-specific solutions, too
- Reliable results through our own calibration laboratory
Special solutions are beneficial - even for small quantities. Ask us!
From the first conversation to series production
It starts with a short technical conversation: wavelength, required irradiance, available space, cycle time and how the waste heat can be dissipated. From this we derive a design that we verify in optical simulation before anything is built – the irradiance distribution on the part can be assessed while it is still a drawing.
Test samples follow and, if required, small batches or series production. Every system is measured in our calibration laboratory before delivery. On request we supply the matching UV sensor for continuous monitoring in operation.
Customized UV LED solutions arise where installation space, wavelength, irradiance or interface depart from the standard – and where an adaptation costs less than a compromise in the process.
Spectra of the customized UV-LEDs
For customized solutions the UVC LED joins the four UVA wavelengths, the range for disinfection and surface treatment. The two figures show the emission bands separately: above the UVA and blue wavelengths from 365 to 450 nm, below the UVC modules with peak wavelengths between 265 and 280 nm. Around 90 nm without emission lie between the two ranges – no single LED bridges that, which is why two LED types are combined in one housing.
Safety instructions
The device emits UV radiation and blue light. UV radiation is invisible. Any visible light is only luminescence excited by the radiation; it is usually much weaker than the exciting UV radiation. The irradiance of the device is several hundred times stronger than that of sunlight.
UV radiation can cause cataracts in the lens of the eye and inflammation of the retina. Always wear suitable UV protective goggles when operating the device. UV-A also causes skin discolouration and skin ageing; use suitable clothing, gloves and further personal protective equipment - depending on the irradiation dose.
The devices are designed and classified according to DIN EN 62471:2009-03 "Photobiological safety of lamps and lamp systems"; the systems fall into risk group 3. Do not look into the LED and do not expose the skin to the UV radiation permanently.
We are glad to support you in setting up UV workplaces and with the risk assessment according to DIN EN 14255:2005.
Publications using Opsytec UV LED light sources
We do not keep a separate bibliography for this individual device – publications usually name the product family, not the model. Listed here are the 10 most recent works in which Opsytec UV LED light sources were used.
