EMI receivers are a very good tool for analyzing EMI spectrums. This article will investigate alternatives such as spectrum analyzers. We will see how LISUN’s EMI receiver fares in the market in terms of standard compliance. EMI receivers EMI receivers are data gathering instruments. These have high performance for analysis. EMI receivers are useful when transient signals or spurious emissi...
Electromagnetic interference is one of the most difficult problems to solve when producing an electronic device. It is also known as EMI. The influence of these inevitable interferences on the instrument’s performance need to be carefully monitored. This is done to comprehend and quantify the electromagnetic compatibility of the instrument under test. Efforts are made to lessen the impact of...
IEC Certified Dust Test Chambers Are Correct Dust Testers Introduction Dust is intrusive contamination that can influence electronics and some other forms of equipment or machinery to overheat and malfunction. The manufacturer can verify their devices can withstand dusty surroundings by becoming well-sealed or undisturbed through such contamination by using the dust tester provided by different Du...
In September 2020, the DLC released the official version of the Grow Light V2.0 standard, which will be implemented on 21st, March, 2021. Prior to this, all DLC applications for plant lights will continue to be reviewed according to the V1.2 standard requirements. The updated content of the official version of the plant lamp V2.0 Keep the requirement of V1.2 version PPE≥1.9μmol/J unchanged In t...
As we all know, UV actually includes 3 bands, from 320nm~400nm, UV-A of low frequency and long wave to 280nm~320nm, UV-B of medium frequency and medium wave, and then to 100nm~280nm, UV-C of high frequency and short wave. Application of UV Light in Different Bands As one of the LED market segments, UV LED can be said to be in its infancy and is expected to have high growth in the future. Correspon...
EDX-2 RoHS Testing Equipment Introduction EU Legislation has established a mandatory standard known as RoHS. It stands for “Restriction of Hazardous Substances” (Restriction of Hazardous Substances). We have formally implemented this standard since July 1, 2006. It is mainly used to regulate the materials and process the means of electrical and other electronic products. RoHS Test Equipment Th...
What is a ball pressure test? Under the action of high temperature, the structural properties of non-metallic materials and insulating materials will change greatly, and this change is usually manifested as material softening or melting. The IEC ball pressure test is used to test the heat resistance of non-metallic materials and insulating materials. In the safety standards for products such as pl...
What is a power surge? Power surges are abnormally high voltage spikes occurring on the AC power. Their short duration, high energy events indicate that they are both very fast and very large. Several conditions affect the quality of power. These conditions include sags, brownouts, blackouts, swell lines, noise surges, temporary over voltages, and sustained over voltages. Power surges are the most...
Photometry LISUN is an independent lighting and optical test laboratory for testing LEDs, lamps, luminaries, displays, signs, and vehicle lighting. Photometry is the modern science used for the measurement of visible light regarding its perceived vision brightness to the human vision. The SI unit of photometry is lumen (lm). The two laws used in photometry are inverse square and cosine laws. The i...
