The ESD test is used to determine the durability of electronic devices when electrostatic discharge occurs when a person touches them. These tests can be conducted with the help of lightweight and portable electrostatic discharge simulators, also known as ESD guns. This article will demonstrate how to conduct an ESD test using LISUN’s electrostatic discharge simulator. What is ESD Testing? E...
A Goniophotometer is a device used for measuring the light emitted from an object at multiple angles. Goniophotometers can measure the properties of light that are emitted by a light source. They have been used frequently for the last few years with the increase in advancements. LED light sources have been introduced in the last few years. These are mostly directed light sources, and light is not ...
What is an Environmental Chamber? An environmental chamber, also known as the climatic chamber or environmental test chamber, is an enclosed space for testing the effects of specific environmental conditions on the environment. These chambers are also known for stimulating corrosion by introducing a salt spray into the chamber. The function of an Environmental Chamber The major function of the cl...
The photometric center of a lamp or luminaire is the reference point, from which the photometric distance law is applicable. This appendix lists two methods to determine the photometric center as EN and CIE standard. According to EN 13032-1:2004 Picture below s quoted from EN 13032-1:2004 (Measurement and presentation of photometric data of lamps and luminaires—Part 1: Measurement and file forma...
Surges are a concern for every circuit developer since they are key problems in electronics. These surges are known as impulses. Impulses have the distinct characteristics of high voltages, typically in the kV range, that remain for a brief period. The features of an impulse voltage can be characterized as a high or low fall time. These impulses are followed by a very high voltage increase time. A...

The EMI receiver is one of the most useful devices to be used in an EMC test chamber in an Electromagnetic Compatibility (EMC) laboratory or engineering facility. EMI problems are frequently encountered throughout the early phases of the product development cycle and measuring receivers of several types are employed to identify and rectify these issues. An EMI receiver is used to perform testing f...
What is goniophotometer definition? LISUN LSG-1890B/LSG-1800A goniophotometer is automatic goniophotometric instrument for luminous intensity distribution measurements with facility for rotating the light source. LISUN LSG-1890B/LSG-1800A uses a constant temperature detector, Japanese motor and German precision angle coder which keep the test results with high accuracy. It is for industrial labora...
What is the function of Environmental Chambers? Temperature, humidity, air pressure, light, and motion can affect the performance of a product. The environmental chamber can be used to observe the performance of a product under certain conditions. It also helps extend product lifetime and examine the aging process. High and Low Temperature Humidity Chamber It is meant to copy a given environment s...
