PowerBar V3 UVA Nichia LED Module With Lens System

The PowerBar V3 UVA LED modules are high-quality lighting solutions designed for applications demanding significant radiant power per square meter, including medical, industrial or commercial. Each 28 cm module features 12 powerful Nichia UVA LEDs, delivering an impressive UV light output of up to 20,000 mW at a 120° angle. The aluminum PCB enhances heat management, and an NTC resistor allows for temperature monitoring via an external control unit.

One PowerBar consists of 12 connected segments, each measuring 28.5 x 23.85 mm, which can be separated and used individually. Terminals on the first and last sections simplify connection without soldering, enhancing ease of use.

To increase versatility, the PowerBar V3 modules include holes for easy lens mounting, compatible with lenses from Ledil and Carclo available in our shop. These modules are designed for dimming and constant current operation, ensuring consistent performance. The PowerBar V3 system's accessories, such as various heat sinks, mounting clips, and individual lenses, allow for the creation of custom luminaires tailored to specific needs.

 

Violet UV LED Strips & Irradiation System

The Violet UV LED strips are the platform on which complete UV irradiation systems are built. Each strip is 281 mm long and carries 12 UV LEDs on an aluminium PCB, at a fixed pitch matched to the LEDiL VIOLET-12X1 optics family. Because the optic is designed around the board, the beam is defined and repeatable — the irradiance reaching your target can be calculated from the optical data instead of estimated on site.

Wavelengths cover the full germicidal and photobiological range: UVC at 265nm, 275nm and 280nm for disinfection and sterilisation of surfaces, air and liquids; UVB at 295nm, 308nm and 310nm as a mercury-lamp alternative for phototherapy, material testing and agriculture; and UVA at 330nm for curing, fluorescence and inspection. Radiant output reaches 1800mW per strip, with LEDs from Nichia, Bolb, ams OSRAM, Seoul Viosys and NKFG. All wavelengths are above the ozone-formation threshold, so the systems operate ozone-free.

The Violet strip can be used as an individual LED module or as the basis of a complete UV irradiation fixture. A dedicated aluminium housing, matched optics, constant-current drivers and dimming/control solutions are available, including configurations with PowerController V2, LEDIM/D1, LEDIM/D2 or Mean Well LCM drivers. This makes it possible to build anything from a simple dimmable UV source to a controlled multi-module irradiation system.

For OEM projects, we can also assist with selecting the wavelength, optics, working distance, number of modules and driver configuration according to the required irradiation area and target irradiance.

Violet300–1200 Complete UV Light System

The Violet UV light systems take the Violet strip platform and deliver it as a finished, sealed luminaire with the driver and control electronics already built in. Each fixture combines the 12-LED UV boards with matched LEDiL optics inside a hard-anodised aluminium housing rated IP65, cooled passively by free convection with no fans and no maintenance. Connect a 30-50V DC supply to the 3m silicone cable and the system runs — no external driver to specify, no constant current to calculate, no optic to align.

Four sizes scale by repeating the same module: Violet300 (12 LEDs, 296.5mm, <29W), Violet600 (24 LEDs, 593mm, <58W), Violet900 (36 LEDs, 889.5mm, <86W) and Violet1200 (48 LEDs, 1186mm, <116W). Each is available in four wavelengths — 265nm and 280nm UVC for disinfection and sterilisation, 308nm UVB as a mercury-lamp alternative for phototherapy and material testing, 330nm UVA for curing, photocatalysis and fluorescence — and in four beam patterns including an oval optic for conveyors and continuous web material. Radiant output ranges from 680mW to 4100mW depending on configuration, all ozone-free.

64 configurations are available, built to order. Tell us the target, distance, area and required dose and we will calculate the configuration for you.

Important information:

• Safety precautions when using UV light sources must be respected, as detailed in  IEC Standard 62471:2006, ‘Photobiological Safety of Lamps and Lamp Systems’, EU-Directive-2006-25-EC or the applicable standard for your country
• We are not responsible for the damage, on the health of well-being or to property for the incorrect use of UV light sources
• For killing viruses or bacteria with UV, they must be directly exposed to the radiation. Dirt and other impurities that shade the microorganisms will severely limit the effectiveness of UV disinfection
• UV disinfection is only one of the weapons to fight virus and bacteria. Personal hygiene (washing of hands), not touching the face, using disinfection on dirty surfaces must also be practiced when fighting a pandemic.
• The percentage of the disinfection for any given virus or bacteria on a surface, object, in the air, water or on clothes is depended on the type of pathogen, the wavelength of the UV radiation, its irradiance in Watts/m2 and the time of exposure, measured in seconds, minutes or hours.
• 100% disinfection is not guaranteed. Similarly, no vaccine, medicine or surgical procedure is 100% effective. UV radiation will just reduce the chance of contamination of the surface, air or objects with viruses or bacteria to cause a disease
• Examples of combination of wavelength, radiance and exposure time for some common pathogens are found in the article in our blog
