1. What is a conducted disturbance test? 1.1 Introduction of conducted interference: Electromagnetic interference (EMI)-The interference signals generated by electronic devices are transmitted through wires or public power lines, and mutual interference is called conducted interference. Conducted interference has brought confusion to many electronic engineers. How to solve the conducted interferen...
The goniophotometer is mainly used to measure the light distribution performance of lamps and light sources. That is, the luminosity and chromaticity value distribution of the laser source of lamps in different directions in space. 1. What are the main types of goniophotometers and what are the test methods? 1.1 Types of goniophotometer Goniophotometers are mainly divided into two types: horizonta...
Metal components, zinc plated nuts and bolts, surface coatings, and paint may be tested for corrosion resistance in salt spray test chambers or salt fog chambers. It is possible to test the suitability of a layer for use as a protective finish on finished items in such chambers, where coated samples are placed in a simulated corrosion environment. Corrosion-resistant samples are tested for a certa...
The standard specifies that the size of the integrating sphere is based on the size of the lamp under test. But experts explain that for many product development and testing purposes, smaller spheres can provide acceptable measurement accuracy. 1. What is the function of integrating sphere and what is integrating sphere? 1.1 Integrating sphere instruction: The integrating sphere is a quick and con...
It is possible to test the reaction of goods when they are exposed to fluctuations in humidity by using a humidity chamber. This chamber is also called an environmental chamber. Manufacturers utilize this form of environmental testing to put their goods through their paces under the most extreme circumstances possible before releasing them. Humidity chambers are used to evaluate the impact of vari...
To integrate radioactive flow, an integrating sphere is needed. In many applications, the integrating sphere is used to measure optical radiation straightforwardly. A thorough understanding of how the integrated sphere works are required before designing a sphere for a particular application. Diffuse reflective surfaces have a crucial role in determining how light travels across the globe. The ill...
The myopia rate of primary and secondary school students remains high. More and more people are advocating to pay attention to the improvement of students’ eyesight and the healthy lighting of classrooms, especially parents of students and classrooms. The education industry has also issued relevant standards, such as classroom lighting and lighting hygiene standards in primary and secondary ...
The concept of electromagnetic compatibility IEC 60050 (161) is equivalent to GB/T4365-1995 “Electromagnetic Compatibility Terminology”, which defines EMC as “equipment or system can work normally in its electromagnetic environment and does not constitute unacceptable electromagnetic the ability to harass.” Electromagnetic compatibility is the research that under the condit...
Foreword: With the rapid development of the LED industry, the application range of LED lamps is becoming wider and wider, and there are more and more types of lamps. Flat light is one of them. Flat light is suitable for indoor lighting such as living room, bedroom, corridor, kitchen, viewing balcony, etc. At the same wattage as traditional lighting sources, flat panel lights are energy efficient, ...
