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 8000 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.
With the multi-channel LEDControl 5S, up to 5 UV LEDs can be controlled individually. The LEDControl is cascadable and can be configured as master or slave. Remote control can be done via RS485, USB or RS232 for each channel and enables the use in industrial production. Other digital and analog inputs are also available as an option.
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.
