UV LED energy meter

There are more and more applications of UV LED curing in industry.Everyone thinks this will be a trend that will slowly replace the traditional non-energy-saving and environmentally friendly mercury lamp curing technology, and then professionally test the energy meter of UV LED lamps. Start to rise slowly.
 UV LED light source is monochromatic light, the wavelength range is 390nm ~ 400nm, the energy of visible light starts from here. The closer to visible light, the more prone to problems when curing. High-pressure mercury lamps, gallium lamps, and iron lamps produce ultraviolet energy that is not efficient enough and consumes energy. Only about 1/4 produces ultraviolet rays. New energy such as LED will convert all power to the part that needs to be obtained.
   The vast majority of ultraviolet lamps have a spectrum of 200nm to 400nm, emitting different wavelength bands, and there is always a part that can be used. So we use different photoinitiators to generate new energy to do different things. The energy use of the UV lamp is also related to the pigments in the ink. In addition to the ink, there is varnish. Varnish is usually used to achieve a certain surface effect. UV LED is not very effective when curing varnish film. Although there are various obstacles, it will not affect the application of this new technology to other fields. This technology will also be used in other industries to be improved to allow more people in more industries to accept it.
   Speaking of the curing speed of UV LEDs, there is a lot of controversy. Some people doubt that the printing speed of UV LEDs will be limited. The power of UV LEDs is very low compared to mercury lamps, but it can be increased by multiple modules. When the power is increased, the LED needs to be cooled. Therefore, the final cost must be weighed in use. Will UV LED curing technology become a trend?
  Now that you have UV LED curing technology, you must have a UV LED energy meter that detects the UV LED curing light source. Because UV LED curing is a late rise, the country has not issued a corresponding verification procedure for the detection standard of UV energy meters for UV LED light sources. For the accuracy and stability of the detection data of the UV LED energy meter, there are also differences between different brands. Under such circumstances, the calibration of the UV LED energy meter can only be completed by the respective manufacturer to ensure the accuracy of the UV LED energy meter.
