High UV irradiance combined with a uniform irradiated area is the key feature of the surface LED series SFL-UV.
The SFL-UV modules are water-cooled high-power UV LED sources with an intelligent LED driver. The absence of ineffective infrared radiation reduces the heat compared to conventional UV lamps.
Three standard sizes are available with light-emitting areas of 100 x 100 mm to 200 x 200 mm. Customized sizes are available on request.
Independent of size, we offer two versions. The HO versions reach high irradiance of up to 5500 mW/cm², while the ECO versions still offer up to 2000 mW/cm². Both irradiances are measured at a distance of 10 mm to the emitting window.
The high irradiance allows extremely short processing times. Wavelengths of 365, 385, 395, 405, and 450 nm are available for many different applications.
For the control of the UV LED floodlights, we offer the LedControl S as a desktop device or the LedControl DC for a top-hat rail mounting. For this purpose, we deliver the UV area lamps with corresponding interfaces.
The LEDControl S can be configured as master or slave and can be cascaded as required. With the multi-channel LEDControl 5S up to 5 UV-LEDs can be controlled individually. Control is via RS485, USB or RS232, making it easy to use in industrial production. Additional digital and analog PLC inputs are also available as an option.
The LEDControl DC is optimal for integration into a PLC and achieves a high performance level.
A timer for the irradiation times between 0.01 s and 9999 s is already integrated. Optionally you can choose between continuous or triggered operation.
The large-area UV LED light source operates reliably with optional internal and external control. The optical feedback option allows for connecting an external sensor to the SF-UV-LED driver. The irradiance can be measured with our long-term stable UV sensors at the desired position. To monitor and control irradiance, the internal feedback diode can be calibrated to the external sensor. The internal feedback keeps the irradiance constant to minimize LED temperature drift and aging.
