With more advancement in LED technology and manufacturing, UV LEDs are more widely used in the industrial application, eg UV curing industry. UV curing is a necessary process in which ultraviolet light rapidly cure the adhesives, coating or inks. These days high intensity UV LED source are now the go to solution for curing industry.
While flexibility is one of the main advantages to LED technology brings to the curing industry, it also means more details are required to specify the right performance for Curing. To select a reliable UV curing lamp, several factors need to be considered.
- Peak wavelength
Peak wavelength is important to consider for the UV curing lamp. That is because the materials and inks can be cured much better and faster under UV-A at 365NM. With LEDs, the peak wavelength can vary. We need to ensure the correct LEDs are used when UV curing lamps are manufactured but also that the electronic and mechanical properties of the UV-A light do not damage the UV-A LEDs with excessive heat. To make sure that an LED UV-A lamp can cure the materials much better and high efficiency. The LEDs must have a peak wavelength within the range 360-370NM, irrespective of the time they operate.
Beam Profile
The beam area of an LED UV-A lamp is the UV-A surface that is covered on the materials to be cured. This is minimum required for an inspection. The covered area varies significantly, depending on the light used. A UV Curing lamp with wider beam profile, you can cure the material more reliable and much faster. You can certainly save a lot of cost and labor in the real service.
Portability
An UV curing lamp can operate on battery power for several hours is quite reliable for most curing application. Cos for auto industry, you need to move around to cure different parts and position. A portable curing device can be more helpful for the operators.
These days, Sunlonge launches the SL8803T hand-held UV LED lamps, 3 pcs 365NM UV light source, UV intensity up to 38 000 uw/cm2 at 15 inch, hand-held design with super wide beam area. This model is expected to be ideal UV curing lamp for the UV curing market.
