COOLLED precision instrument sets new standards in UV curing

The COOLLED Precision UV LED curing system is a desk top instrument that uses COOLLED technology to generate a flood of high intensity, single peak wavelength of UV light for the curing of inks, coatings and adhesives.

Designed to replace conventional mercury lamp curing boxes, the light source of this innovative new product is an array of semiconductor light emitting diodes and the system has many benefits over conventional curing methods.

The light is available instantaneously with no warm up required and cold curing is available close up to the cure head so there is no heating of substrates. In addition, the output power has one peak wavelength and there is no fuming of cured material that is often caused by excessive radiant power from conventional lamps.

LED light sources are also a safer option. There is no UVB, no ozone, no bulbs to break or age and no mercury. They operate from a low voltage, have a predictable radiant output power with limited degradation during product life and can be programmed for either a single power level or a variable cure profile.

On the COOLLED Precision UV curer the LED array is built into a remote housing connected to the main instrument via an umbilical flexible hosing that supplies the necessary power, cooling and temperature sensing. This configuration enables the array to be positioned close to the items being cured. The main instrument contains a water-cooled heat exchanger and pump, the necessary power supplies and a microprocessor board with a display for the control of the LED intensity and switch on times. Spectral output is 385-410nm, primary peak is 395nm power requirements 110-240VAC at 50 or 60Hz and typical output at source is 1.2W/cm2
