Electromagnetic Compatibility EMC refers to the ability of a device or system to function properly in its electromagnetic environment and does not constitute an electromagnetic disturbance to anything in the environment. Sensor electromagnetic compatibility refers to the adaptability of the sensor in the electromagnetic environment, maintaining its inherent performance and the ability to perform ...
Recently Saudi Arabia released new LED standard SASO 2902 for energy efficiency, functionality and labeling requirements for Lighting products. We have got the SASO 2902 in 2017 which is draft and already produce some instruments for some of the Saudi Lab. Such as below products: 1. LPCE-2(9000) High Precision Spectroradiometer Integrating Sphere System. It can test EEI, Energy Efficiency Clas...
If you need to disable the 64bit digital signature enforcement of the computer, follow the steps: For Win 7 system There are two ways and you can use any of them. Restart the computer and press “F8” at the beginning. Then you can enter “Advanced boot options”. Move the cursor to “Disable Driver Signature Enforcement” and press “Enter”. F...
Some customers suspect the accuracy of the WT2080 because there is some differences of the test result between LISUN WT2080 LED Power Driver Tester and multimeter when testing LED power driver. In fact, the test results are different because the test principle is different: the WT2080 test result is the real effective value (RMS), the multimeter test result is the average value. LISUN WT2080 is ac...
The LED is a light-emitting diode, and its characteristic curve is basically the same as that of a normal diode. When the applied voltage reaches the diode conduction voltage, the slight change of the applied voltage can cause a great change in the diode current. The constant current is used to ensure that the current in the LED is constant. No matter how the voltage changes, the current flowing...
LISUN GDJS seriesHigh and Low Constant temperature and humidity chamber is according to IEC60068-2-1 (GB/T2423.1) and IEC60068-2-2 (GB/T2423.2). It is used to test the CFL/LED which meets IES LM-80-08, electricity products, electronic components, material and so on. There is some other manufacturers in China also produce High and Low Temperature Humidity Chamber, and LISUN VS espec temperature ...
Waterproof testing grade reflects the ability of moisture-proof of products. Especially for outdoor activities, it is unavoidable to be in the harsh environment of high humidity. The sealing and water-proof ability of the instrument is very important to ensure the safe of operation and life of the instrument. At present, there are many manufacturers producing waterproofing test equipment ...
In optical testing, the measurement of luminous flux and color temperature are essential. There are two test equipment for the measurement: Integrating Sphere Testing System and Goniophotometer. Here we give you a brief introduction to the difference of goniophotometer vs integrating sphere: 1. Integrating Sphere & Spectroradiometer Test System The Integrating Sphere Test System make me...
The main parameters of LED lamps and lanterns include: A: Electric parameters: voltage, current, lamp power, power factor, harmonic, etc B: Colorimetric parameters: correlated color temperature, color rendering index, chromaticity tolerance, color coordinates, SDCM, etc C: Photometric parameters: luminous flux, output luminous efficiency, beam angle, UGR table, intensity distribution, candela tab...
