Violet900 UVB LED Light 308nm 2111mW 36 LEDs 52x12deg 48V 86W 89cm 3m cable

Violet900 UV-B LED Light 308 nm, 2111 mW, 52° x 12° Beam, 36 LEDs, 48 V, 86 W, IP65, 3 m Cable

The Violet900 UV-B 308 nm is a complete, ready-to-connect UV LED luminaire: 36 UV LEDs on Violet strips, a silicone optic with a 52° x 12° (oval) beam in a stainless steel frame, and a hard-anodized aluminum housing that acts as the heat sink, rated IP65. It delivers a radiant power of 2111 mW at 308 nm and runs on 30 to 50 V DC (48 V nominal) at below 86 W, with PWM dimming and remote on/off via a dedicated control wire, so it can be integrated into process control and switched exactly when irradiation is needed. It is designed for professional horticulture and curing.

Applications of the Violet900 UVB 308 nm 52° x 12° LED Light

As a complete UV irradiation luminaire, the Violet900 UV-B 308 nm is designed for the following main applications:

• Horticulture: supplemental UV-B: Low, precisely controlled doses of UV-B at 308 nm trigger the natural UV response of plants: more flavonoids and anthocyanins for color, flavor and nutritional value, more compact growth and stronger natural defenses. In greenhouses and vertical farms, UV-B treatments supplement the daylight or LED grow light spectrum, for example in strawberry cultivation, where UV-B treatments are used to help control powdery mildew. The dose must be tuned to the crop, because too much UV-B damages leaves. Read more about strawberry cultivation with LED grow lights.
• Curing: UV-B radiation supports the curing of UV adhesives, coatings and resins whose photoinitiators absorb in the short-wave UV range, alone or combined with UVA sources; the LED switches on instantly and emits no infrared heat onto the workpiece. See light for curing.

Choosing the Beam: Violet900 UVB 308 nm Versions

The beam angle decides how the luminaire performs in your application. A narrow beam concentrates the radiant power into a small area and gives a high irradiance at a long working distance; a wide or oval beam covers a larger area at a proportionally lower irradiance, and an oval beam suits long, narrow targets such as conveyor belts. The Violet900 is available at this wavelength with the following beams:

• 13° (narrow): 2387 mW, SKU 44450.40
• 39° (medium): 2236 mW, SKU 44450.41
• 61° (wide): 2415 mW, SKU 44450.42
• 52° x 12° (oval): 2111 mW, SKU 44450.43 (this version)

The dose on the target is the irradiance at the working distance multiplied by the exposure time. Because the LED positions and the optic are defined, the irradiation pattern can be calculated for your geometry before installation.

Violet Modular UV Irradiation System: 265 to 330 nm

The Violet900 is the complete, assembled luminaire level of the Violet modular UV irradiation system. The Violet UV irradiation platform is a modular system for building compact, precisely controlled UV light sources from 265 nm UV-C to 330 nm UV-A. At the heart of the system is our 281 mm Violet LED strip. Each board carries 12 UV LEDs positioned at a fixed pitch specifically matched to the LEDiL VIOLET-12X1 optics family. This allows the same LED platform to be configured with narrow, wide or oval beam distributions, depending on the required irradiation area, working distance and target geometry.

Instead of designing a UV fixture around a generic LED board, the Violet platform combines the LED source, optics, thermal and mechanical housing and driver electronics into a coordinated system. The result is a practical starting point for applications where UV wavelength, irradiance, beam geometry and dose must be engineered rather than simply approximated. The system can be purchased at different levels of integration: from the bare LED strip and optic through to a complete assembled UV irradiation fixture.

A Modular Platform Built Around a 281 mm UV LED Strip

Every Violet strip uses the same basic mechanical platform:

• 281 mm LED board length
• 12 UV LEDs
• Fixed LED pitch matched to LEDiL VIOLET-12X1 optics
• Multiple UVA, UVB and UVC wavelengths
• Constant current operation
• Compatible mechanical housing available
• Different driver and dimming architectures
• IP67 optical configurations possible with suitable VIOLET-12X1 components

Because the LED positions and optic geometry are defined, we can use the LED radiant output, the selected optic and the working distance as inputs when calculating the expected irradiation pattern at the target surface. This is particularly useful when designing equipment where a specific UV dose or irradiation area is required.

Installation, Operation and Safety

• Power supply: operate the luminaire with a stabilized constant voltage power supply of 30 to 50 V DC (48 V nominal); the current is below 1800 mA and the power below 86 W at 48 V, with 0.1 W standby. Electrical protection class III (SELV).
• Wiring: 3 m silicone cable with open ends, 3 x 1.5 mm²: brown +Vin, blue GND, green/yellow DIM. Check polarity before switching on.
• Dimming and switching: the DIM conductor accepts a PWM signal of 100 Hz to 1 kHz and works as a remote on/off input: on with dimming at more than 2.5 to 5 V DC or open, off at less than 0.8 V DC or GND. If the DIM conductor is not used, insulate it and do not connect it.
• Mounting: fix the luminaire with the stainless steel mounting brackets and star knobs; the brackets allow aiming through about 105°. Do not overtighten fixings, bend the housing or put mechanical stress on the optical window and cable.
• Environment: the luminaire is rated IP65 and cooled by free convection through its housing; the operating temperature at the Tc point (center of the housing front, next to the optic) is -40°C to +60°C, the ambient temperature -40°C to +35°C, with maximum 90% non-condensing humidity. Avoid aggressive chemicals, and assess the complete installation for the intended environment and cleaning process.
• Optical radiation safety: hazardous ultraviolet radiation, risk group RG3 (EN 62471). Operate the luminaire only with the shielding, access control, interlocks and personal protective measures required for the application, avoid direct, unprotected viewing of the optics and prevent skin exposure. Observe the national regulations on artificial optical radiation at the workplace.
• Installation: disconnect the supply before installation, wiring, adjustment or service; installation must be carried out by a qualified electrician in accordance with the applicable standards.
