UV Integrator for LED and High Pressure Mercury Lamp

From:Linshang Time:2019/10/26 14:10:00 Browse:213
The high-pressure mercury lamp and the LED light source have different spectrum, when we test LED light source, we need to use UV LED integrator.

In the process of selling UV integrators, customers often ask, "Why do we need to use different UV integrators for mercury lamps and LED lamps?  If we have two kinds of lamps, do we need to buy two kinds of UV integrators? Now, let’s find out the answer of this question.

1. Reasons for choosing different UV integrators for different light sources

First, the spectrum of the mercury lamp and the LED lamp source is different. The curing band of mercury lamp is mainly 365nm. While the curing band of  LED light source can be 365nm, 375nm, 385nm, 395nm, 405nm. Linshang Technology has invented dedicated UV integrators for different light sources. The spectral response range of the Linshang UV integrator for mercury lamp is 315nm-400nm. The spectral response range of the UV LED integrator is 340nm-420nm. 

Therefore, we need to select the instrument that matches the spectrum of the source when measuring. When the spectrum of the source is inconsistent with the response spectrum of the instrument, the measured data will be inaccurate.

UV integrators

Most of the UV integrators on the market are designed for high pressure mercury lamps and are only suitable for testing energy and intensity values at 365 nm in mercury lamps. However, for the LED light source, there are not only 365 nm, but also various bands such as 375 nm, 385 nm, 395 nm and 405 nm. Therefore, for the LED light source, it is necessary to use a dedicated UV LED integrator.

2. What will happen if improper UV integrators are used?

Of course, for some customers they don't want to buy two UV integrators. Then, using a special instrument for measuring LED to measure mercury lamps. The test data is stable but the data will be too large and cannot pass the inspection of the metrology institute. However, there is no problem in controlling the production process. Using a special instrument for mercury lamps to measure LED lights, the data will be too small.
Therefore, users can determine whether they need to purchase two UV integrators according to their actual situation.

The Linshang integrated UV integrator mainly has four models: LS131, S128, S130 and S120.
