Six Factors to Consider when Chooses UV LED Curing Machine

First, How to control UV Energy exactly?

1. For UV Curing Machine, UV Energy (mJ/cm2)=UV intensity (mW/cm2)*time exposure (S). Therefore, for exactly control UV intensity and time of exposure, you can exactly control UV Energy.

2. For time of exposure control, advanced UV Curing Machine, insided shading type electronic shutter, can set time of exposure.

3. For UV intensity control, generally speaking, power board adjustment is used to control the air ratio. At present, only can reach 50%-100%. Because the light bulb is needed a certain current to keep the glowing state.

Second, How about the distribution of UV intensity in UV Curing Box?

In general, UV intensity of UV Curing Machine is not as uniform as you might think. If you can not control well interior reflector and light bulb design, UV intensity will change a lot.

The UV Curing Box of Guangdong SpaceLight Technology Co., Ltd. (www.leduvcuring.com) has matched reflector, but UV intensity will go down with the direction of light bulb, which the farthest distance (+/- 4 inch) is down by 40%. The power can be adjusted from 1%-100%, the range of intensity is 600mW/cm2-100mW/cm2. However, if you cure the small area, the intensity will be uniform, such as +/- 2 inch, the intensity is between 80mW/cm2 and 100mW/cm2.

Do not chose what is called “uniform”UV Curing Machine without any datum.

Third, How about UV Spectrum?

At present, due to the development of light curing, has appeared many applications, like surface curing, visible light cure, etc., and also has appeared light bulbs of UVA, UVB, or visible light enhancement mode. Advanced UV Curing Machine can match different spectrum without any hardware change, just changes the light bulb, which can greatly enhance the flexibility of research and development.

Forth, How to demarcate UV Energy?

Generally speaking, process conditions or test data cant not do without quantitative conditions. Aim at UV Curing Machine, it needs to be measured UV Energy and UV Intensity by UV Energy Meter, which is essential aim at UV Energy of UV Curing Machine. UV-150 Energy Meter is a meter of highly economical type for UV Curing Machine.

Fifth, Safety and Temperature Control.

Advanced UV Curing Machine is with locking the door, opening the door, closing the shutter automatically, and protect the user’s safety. Other designs are including good ventilation condition and automatic standby function, effective control temperature rise. But, what calls for special attention is that, temperature without good control light source will cause the serious hidden danger of bulb blowout.

Sixth, Stability and Reliability.

This is hard to prove directly. It’s the accumulation of industrial experience. The general laboratory is usually not equipped with a machine. An unstable light source has a serious impact on the relevant test schedule.
