- Developed and manufactured in Germany
This Violet UVC LED strip is the 281 mm light-engine core of the Violet modular UV irradiation system. It uses 12 Nichia NCSU434D emitters at 280 nm and provides approximately 1620 mW typical radiant power.
The LED pitch is fixed for compatibility with the LEDiL VIOLET-12X1 optics family, allowing the bare module to be turned into a controlled UV source with narrow, wide or oval irradiation patterns instead of relying only on the native LED beam.

Violet modular UV irradiation platform
Violet is a modular system for building compact, precisely controlled ultraviolet light sources. The common platform is a 281 mm rigid LED board carrying 12 UV emitters at a fixed pitch specifically matched to the LEDiL VIOLET-12X1 optics family.
Because the LED positions and optic geometry are defined, the same board can be configured with different narrow, wide or oval optical distributions according to the required irradiation area, working distance and target geometry. This is fundamentally different from placing a generic UV board behind an arbitrary lens: radiant output, optic, distance and target area can be considered together when engineering the irradiation pattern.
The platform can be integrated at several levels—from the bare LED strip and optic through to a mechanically housed and driven UV irradiation fixture. Compatible mechanical housing, different constant-current driver and dimming architectures, and IP67 optical configurations can be used where the selected VIOLET-12X1 components and complete mechanical design support them.
Design from irradiance and dose, not radiant power alone
Radiant power in milliwatts describes the total UV output of the LED module, but it does not by itself describe the UV level received by the target. The useful engineering quantity is irradiance at the target surface, which depends on the emitted radiant power, selected optic, working distance and illuminated area.
Where a process is dose-dependent, exposure time must also be included. A narrow optic can raise irradiance over a smaller area, while a wider or oval optic can cover more surface at lower peak irradiance. This is why the Violet platform is designed around a coordinated LED-and-optics geometry rather than a bare source alone.
Germicidal irradiation and disinfection equipment
The 280 nm UVC output is intended for professional air, surface and water irradiation systems, laboratory equipment and industrial process systems where germicidal UV is part of a validated treatment process. See our overview of UV disinfection technology.
Required biological effect depends on organism, irradiance, dose, shadowing, surface condition and process geometry. A finished disinfection system therefore requires application-specific validation rather than assuming that nominal wavelength or radiant power alone guarantees a target reduction.
Constant-current driver and thermal integration
This Violet board requires a regulated constant-current LED driver. The reference operating point is approximately 1050 mA (maximum 1500 mA) at 21.0 V and 22.05 W. The driver output range, dimming method and protection functions must be matched to the selected module and final control architecture.
An external heat sink is required. UV LED radiant output and lifetime are strongly temperature-dependent, so the completed fixture must provide an adequate thermal path and keep case and ambient temperatures within the specified operating limits.
The bare board can be integrated with the Violet mechanical housing and optics to form a complete UV source. Where interlocks, motion sensing, door contacts, emergency-stop logic or 0–10 V control are required, these functions should be engineered and validated at complete-system level.
UV safety for professional equipment
This module is classified in EN 62471 risk group RG3 and is intended for professional integration. Direct or reflected ultraviolet radiation can injure eyes and skin. The completed equipment must provide the shielding, access control, interlocks, warning labels and operating procedures required for the wavelength, irradiance and exposure time of the application.
Do not size safety measures from visible brightness: UV radiation may be hazardous even when the source appears dim or is invisible. Risk assessment must be based on the optical radiation emitted by the finished system.
Manufactured in Germany for controlled UV system integration
We develop and manufacture the Violet UV light engines in Germany using specified UV emitter components and controlled SMT production. UV modules are electrically and visually checked so the complete irradiation system starts from a repeatable PCB, LED layout and electrical design.
For OEM projects, we can also support wavelength and LED selection, PCB adaptation, optics, thermal design, control electronics, prototyping and series production. This allows the complete irradiation source to be engineered around the required wavelength, working distance, target area and dose.
The current product documentation specifies a five-year commercial warranty, subject to the applicable warranty conditions. UV LED ageing and radiant-output depreciation remain dependent on junction temperature, drive current and operating conditions.
