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, ...
A key design challenge in designing a power bank is passing EMI testing. Electronics engineers often worry about failing EMI tests. If the circuit EMI test fails many times, it will be a nightmare. You will have to work around the clock in the EMI lab to fix problems and avoid delays in product rollouts. For consumer products such as power banks, the design cycle is short and the EMI certification...
On 9th ,October, 2018, the Illuminating Engineering Society of North America (IES) released a new version of the light source color quality evaluation standard – IES TM-30-18 Method for Evaluating Light Source Color Rendition (evaluation of light source color reproduction method), with a partial update to the legacy documentation. Compared with the old version of the document released in 201...
At present, the withstand voltage tester seen on the market adopts the GB4706 (equivalent to IEC1010) standard, and the AC/DC withstand voltage and insulation resistance three-in-one withstand voltage tester with desktop structure is mostly used, which can basically meet the needs of users for testing. And most of the withstand voltage testers on the market currently use the microprocessor-control...
