- 281 mm modular UV light engine with 12 LEDs matched to LEDiL VIOLET-12X1 optics
- Typical radiant power: 1080 mW
- Maximum specified radiant power: 1578 mW
- Peak wavelength: 308 nm
- Native beam angle: approximately 110°
- Constant-current operation
- Developed and manufactured in Germany
This Violet UVB LED strip is the 281 mm light-engine core of the Violet modular UV irradiation system. It uses 12 Nichia NCSU434B emitters at 308 nm and provides approximately 1080 mW typical radiant power / maximum specified 1578 mW.
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.
Wavelength-specific curing and process irradiation
The 308 nm output can be used in UV curing and photochemical processes where the initiator or material has useful spectral sensitivity in this band. The VIOLET-12X1 optics allow irradiance to be concentrated or spread according to the process width and working distance.
Material compatibility must be checked for the exact wavelength. UVB and short-wave UVA process performance can differ strongly from conventional 365–405 nm curing systems.
Supplemental UV for controlled-environment horticulture
The 308 nm UVB version can be used in research and controlled-environment horticulture where a deliberately limited UV component is part of the lighting strategy. See our broader guidance on supplemental crop lighting.
UVB exposure must be designed separately from PAR lighting because the required dose is crop- and objective-dependent and excessive exposure can damage plant tissue. Irradiance, exposure duration and distance should therefore be validated for the specific cultivation protocol.
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 20.0 V and 21.0 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.
