UV curing devices, can be classified into two light source system : UV mercury lamps/halogen lamps and UV LEDs.
UV mercury lamps/halogen lamps：Have a wider range of wavelengths, providing better effects for specialized UV adhesives or materials with poor surface drying properties. However, since these types of light sources also emit visible light and infrared.
UV LED：Provide a single wavelength based on the LED chip used. They have the advantage of lower temperature, instant on/off without the need for gating mechanisms, and longer lamp life. However, due to their narrow wavelength, they may have less effective curing results for certain UV adhesive materials. Therefore, UV LED light sources are often used in combination with mixed wavelength configurations.
