We all know that in the selection of [UVLED curing equipment], according to the different nature of UV glue and UV ink light intensity demand, we need to test the light intensity of UVLED light source equipment, so as to achieve the accuracy of the data. In the light intensity test, the first thing to meet the uniformity of UVLED curing machine light source, the current UV curing equipment provided by Coinu precision Optoelectronic light uniformity can reach more than 95%, so many partners like to use Coinu brand UVLED light source to calibrate the illuminometer, to ensure that the test effect is more accurate.
1.[UV illuminance meter] light test
Today, we will show you the light intensity test of the UV illuminometer of Koinu Photoelectric Technology. Next, we will introduce what aspects we need to pay attention to when testing.
We need to know that when the UVLED curing device is started, the ultraviolet light source emitted is not the same in all places, and it is also affected by the test distance, so the UVLED illuminance meter is very different for different positions or different distances.
By not using the Angle to test, such as the probe under the light source and oblique below, the obtained reading value is not the same, the larger the Angle of deflection, the greater the numerical error, so in the test, be sure to keep the probe in the center of the light source, so as to get accurate test results.
2.UV illuminance meter light intensity test at different distances
We have prepared a 100×100 size UVLED curing machine, the light uniformity of this UV light source is better, at this time, we need to put the probe test surface of the UV illuminance meter at a certain distance to test, the closer the distance, the higher the light intensity, the farther the distance, the light intensity will gradually decay, which needs to determine the light distance according to the actual use needs. Here, we perform light intensity tests at different distances according to the requirements of different customers.
First of all, we use a remote light source to test, UVLED surface light source (irradiation head 100×100) and UV illuminometer probe distance maintained at 250mm, the probe needs to be directly below the light source, while in the test, the probe needs to move between different positions, then we get the light intensity as follows:
Then, we conducted a second light source test, this time using a close light source test, UVLED surface light source (illumination head 150×50) test distance of about 15-20mm, the probe moved to obtain a stable light intensity value.
3. How to choose UVLED light source with UV illuminance meter
In general, the standard of UV illuminance meter measurement on the market is very different, and the industry standards are not unified, like some professional, you can choose the EIT standard in the United States, if you are useful to the UVLED curing light source, it is recommended that you can use the brand of UV illuminance meter.
The above is to explain the UV UV intensity test method related knowledge. Auvcure is a professional manufacturer of all kinds of UVLED point light source, [UVLED line light source], UVLED surface light source and [UV curing machine], and can provide solutions and customization according to the actual needs of customers. The company has Japanese production technology, products are exported to South Korea, Japan, the United States, Brazil and other places, welcome friends from all walks of life to exchange guidance.
