Technical properties

Your benefits

LED technology as a convincing improvement of conventional discharge lamps

 Reduction of operating costs (lower current consumption, low costs for maintenance and spare parts)  At least 20 times longer lifetime in normal use  10 times higher energy efficiency usable for the adhesive compared to discharge lamps  Light generation directly at the lamp head  No heating time  Stable light power at a constantly high level  Continuous intensity control via power supply, no mechanical shutter required

Up to four plug-in LED heads

 Flexible irradiation of multiple bonding areas

Interchangeable lenses with screw fitting

 Specific light focusing (spot size, working distance)

Intensities of up to 12,000 mW/cm2

 Fast adhesive curing, in just seconds  Short cycle times  Fast, reliable serial processes

New generation of LED light sources: LEDs with integrated air cooling (heat sink)

 Typical lifetime > 20,000 h; „On“ time = service life  Constant light intensity  Ultimate process reliability thanks to monitoring of the LED temperature  Steady (non-intermittent) irradiation is possible

Emission spectrum of 365 nm optimized for adhesives

 Optimal curing of photoinitiated-curing DELO-PHOTOBOND, DELO-KATIOBOND and DELO-DUALBOND adhesives  Minimum heat development at the component (cold light source)  No hazardous radiation in the UVB and UVC range; high occupational safety

Easy-to-integrate lamp head

 Any installation position of the lamp heads as appropriate for the component  Easy integration into systems thanks to compact design

Optimum process reliability

Flexibility designed-in In order to be able to meet customer-specific requirements, the control concept of DELOLUX 50 is modular. Up to four DELOLUX 50 lamps can be independently controlled with the external DELO-UNIPRO control module. Irradiation time and intensity can be individually set for each lamp. In addition, the status of all monitored lamp functions is displayed on the DELO-UNIPRO control unit – or alternatively via PLC. The control module is also available as the DELO-UNIPRO Light verson which – as the name suggests – is a „light“ version of DELO-UNIPRO with just the core functions.
