UV-Curing

Our UV curing module is not a stand-alone module, it is part of a UV curing machine assembled by the customer.
The module consist out of the following components:

  1. Stainless steel UV Curing Box
  2. Power Cabinet
  3. Cable Harness consisting out of 2 LED control cables
  4. Temperature control
  5. Fan Power

 

In the stainless steel UV curing box, the UV power from the top is generated by 6 PCBs with each 20 x 20 LEDs with a wavelength of 405nm. The LEDs are equally distributed over the surface of 500 x 700mm which make it homogeneous. At maximum current setting (500mA) this will generate 600mW/cm2 at a distance of 30 mm approximately.

The UV from the sides is generated by 10 PCBs with each 5 x 20 LEDs with a wavelength of 365nm.

The side PCBs are divided in two sections for different purposes; larger and smaller products.

  • The top three rows of a side PCB, 40 LEDs, are provided with a 50° angle. This section is for the larger product, e.g. >15”. At maximum current setting (500mA) the output is approximately 200mW/cm2 at a distance of 30mm.
  • The bottom rows of this side PCB, 60 LEDs, are provided with a 8° angle. These lenses narrow the UV power to a smaller beam to be able to have enough power at larger distances, for smaller products. Output at maximum current (500mA) is approximately 200mW/cm2 at a distance of 80mm.

The top and two side sections can be controlled separately. In normal operation the top section will be combined with either the 8° or the 50° angle, depending on the display size.

The cooling of the UV curing box is done by one radial fan and the system is protected by a built-in safety system.
