1.Light formation 1.1 Introduction Light formation refers to the formation process of organ form structure in the plant life cycle; optical aspirations refer to the process of plant growth, development and differentiation under the conditions of light. This process occurs at any period of plant growth, from germination, nutritional growth, reproductive growth to aging death, and each stage must ac...
What is EMI receiver? Electromagnetic Interference (EMI receiver) is electronic noise that interferes with cable signals and reduces signal integrity. EMI Receiver is usually generated by electromagnetic radiation sources such as motors and machines. EMI Receiver (Electromagnetic Interference) has two types: conducted interference and radiated interference. Conducted interference refers to the cou...
EMI receiver system for EMI (Electromagnetic Interference) radiation conduction or conducted emissions testing. The EMI-9KB EMI receiver is produced by the full closure structure and strong electro-conductibility material, which has high shielding effect. Due to the new technology for the EMI Test System, it solved the instrument self-EMI problem. The test results are according to the internation...
1.Introduction It is one of the most important environmental factors required for plant growth. It is not only the energy source in the process of plant growth, but also an important signal source for plant form. The energy that plants depend on survival comes from the sun. The photosynthesis is an important biological approach to the plant capture light energy. It is one of the decisive factor fo...
LISUN’s Salt spray test chamber The Salt spray test Chamber is used to conduct salt spray corrosive tests on components, parts, electronic and electrical components, metal materials, and industrial products. The salt fog test chamber complies with the following specifications: IEC60068-2-11 (GB/T2423.17), GB/T10125, GB/T1771, ISO9227, ASTM-B117, GB/T2423-18, QBT3826, QBT3827, IEC 60068-2-52, AST...
What components are generally used in an Environmental Chamber? Thermocouple A thermocouple is a moveable device that measures temperature. Product temperature control maximizes stress on the product through the chambers using a thermocouple. Airstream Control vs. Temperature Control The air temperature at the air supply’s outlet source is measured through air stream control. On the other ha...
Integrating sphere The Ulbricht sphere is also known as the integrating sphere. Richard Ulbricht, a German engineer, inspired the Ulbricht sphere. To determine the best lighting strategy, he took photometric measurements. It occurred while preparing the electrical and lighting systems for a train station. He established that the amount of light measured on the opposite sphere wall from the light s...
RoHS testing is necessary in the current market to check for toxic chemicals. In this article, Let’s explain what RoHS is and why it is so important. RoHS testing RoHS means Restriction of Hazardous Substances. The European Union developed the RoHS directive to protect humans and the environment from hazardous substances. The RoHS3 Directive called “Directive (EU) 2015/863,” was ...
What is a Goniophotometer? LISUN goniophotometers can be used to examine angle-dependent optical characteristics of LED and SSL products. This includes everything from single-packaged LEDs to LED modules and light engines. As well as big SSL lamps and luminaires. Type C goniophotometers are built in such a way that their optical axis horizontally aligned. They have a turning luminaire configuratio...
