1. Differences in application areas ESD61000-2 Electrostatic discharge generator is fully compliant with IEC/EN 61000-4-2, GB/T 17626.2 standards and belongs to the category of electromagnetic compatibility. The test object is a device that can work independently, such as LED lamps, and the device is in normal working condition. ESD61000-2_Electrostatic Discharge Simulator ESD-883D HBM/MM ESD Simu...
Before calculating the ErP energy efficiency rating method, we must first determine whether the lamp under test is a directional light source or a non-directional light source. The judgment method is as follows: First, use the goniophotometer system to test the IES file of the tested luminaire. The directional lamp refers to the luminaire whose effective luminous flux is greater than 80% of the li...
LED plant growth lamp is an artificial light source that uses LED (light emitting diode) as the luminous body to meet the lighting conditions required for plant photosynthesis. Classified by type, it belongs to the third generation of plant supplement lamps. In the lack of daylight environment, this kind of lamp can act as daylight, so that plants can grow and develop normally or better. Light env...
The high and low temperature environmental test chamber is also called the high and low temperature cycle test, which is one of the product environmental reliability tests. Basically all products are stored or operated under a certain temperature environment. In some environments, the temperature will constantly change, sometimes high and sometimes low. For example, the temperature in day and nigh...
When the dustproof test instrument fails, stop heating. After the test is completed, first turn off the operation switch, and then turn off the main switch. The air temperature should be kept high enough. Below is Lisun’s dustproof testing machine to specifically introduce the “ What need to pay attention to for dustproof tester”. Precautions for dustproof tester: 1. When the internal dustpr...
The high and low temperature environmental chamber is formed by CNC machine tools, the humidification system pipeline is separated from the control circuit board, and the water system pipeline circuit system is convenient for maintenance and repair. The following is a specific introduction to the “box structure and fault description of the high and low environmental chamber“. Structure...
The functions of the optical integrating sphere tester include light receiving, uniformly illuminated object surface, spherical parallel light tube, etc. Its principle is that after light is incident from the input hole, the light is uniformly reflected and diffused inside the sphere. Below take Lisun’s optical integrating sphere system as an example to introduce it in detail. The role of op...
The lightning surge generator adopts semiconductor electronic switch technology, the waveform is smooth, the output is accurate, supports the judgment of the failure of the sample, and provides a buzzer alarm to ensure the consistency of the surge combination wave. The below is Lisun’s lightning surge generator as an example to introduce it in detail. Features of lightning surge generator: 1...
Goniophotometer is mainly used to measure the light distribution performance of lamps and light sources, that is, the luminosity and color measurement value distribution of the laser source of the lamp in different directions in space. Goniophotometer test system. It is mainly divided into two types: horizontal and vertical. It is mainly used to test the lumens, light distribution curve, glare lev...
