LED technology is fundamentally a more compact technology than traditional ultraviolet lamps enabling much more flexible form factors. The compactness of LED systems, along with the fact that shuttering and air extraction systems are no longer necessary results in a much smaller footprint for the ultraviolet curing system.
There are 4 different LED UV emitters. They generate wavelengths from light emitting diodes (LED) at specific light spectrums of 365, 385, 395 and 405nm. This way people can choose the exact LED based on the spectrum they need for their ink or coating. The reason LED UV emitters are so energy efficient is that they emit only the exact spectrum needed and not any of the unused wavelengths. This saves electricity.
Mercury vapor lamps produce all wavelengths between 260nm and 440nm (nanometers) with various peaks. Some of the energy from a mercury vapor system will be in the infrared spectrum.
LED UV inks and coatings should be tuned to the specific wave length that an LED curing system is producing while conventional UV inks and coating are not specific because mercury vapor lamps cover all of the wavelengths.
An LED based system can offer superior control and stability of output while providing reduced downtime, long lifetimes, and low costs of ownership.
