What is the goniophotometer？ The goniophotometer is the main measuring equipment for the light distribution performance test of lamps, which can be used to measure the spatial light intensity distribution, total light flux and lamp efficiency of lamps or light sources. The goniophotometer system consists of precision turntable and control system, spectrum analysis system, standard lamp, alignmen...
Origin and development of integrating sphere: The use of integrating sphere in measuring luminous flux can be traced back to 1890, and now it has become a widely used instrument in many aspects. The integrating sphere can be used to test the luminous flux, color temperature, light efficiency and other parameters of the light source. It is an indispensable instrument in the measurement of radiance,...
I、 Purpose of environmental test The environmental test examines the adaptability of the product to the environment, determines whether the environmental adaptability design of the product complies with the contract requirements, and provides decision-making basis for acceptance and rejection. A. Quantity of environmental stress used for environmental test In terms of environmental test, 19 te...
Salt spray testing Salt spray testing simulates a corrosive salty environment in the laboratory. It is used to speed the testing of surface coatings’ capacity to withstand air corrosion. It is one of the oldest testing procedures used in the HVAC-R coatings business and, as such, is frequently referred to when selecting HVAC-R coatings. YWXQ-010_Salt spray Test chamber The utility The salt s...
GTS-LS The GTS-LS glare measurement system uses an image luminance meter with great precision. Testing UGR, TI, and GR used in indoor and outdoor light pollution tests is a good idea. Through a precise electronically controlled pan and tilt and specialized measurement and control software, the high-precision measurement and analysis of the unified glare index UGR is made possible. The system is co...
Since the birth of the world’s first semiconductor light emitting diode in the 1960s, LED lighting has been known as the light of hope in the history of human lighting because of its long life, energy saving, rich colors, safety and environmental protection. LED is also known as light emitting diode, is a solid-state semiconductor device that converts electrical energy into visible light, ...
An immunity test called EFT Immunity Measurement (EFT61000-4) is used to evaluate how well electrical and electronic equipment performs when subjected to interference. A device is put through a number of tests to see if it can withstand fast transients like electrostatic discharge and power line transients. Verifying the laboratory’s operating parameters, examining the EFT waveform, running ...
LEDLM-80PL LED Lumen Maintenance and Aging Life Test System is designed according to IES-LM-80 and TM-21, it used to test & record the optical and electrical Maintenance for single LED or LED module, the software is based on Arrhenius model and TM-21 to calculate the LED life. The LEDLM-80PL needs to work with a GDJW/GW Series High Temperature Chamber and and DC12010 DC Power Source. LED...
What is the Surge Test? The surge (impact) immunity test is to simulate the effects of lightning strikes (indirect lightning) in nature and voltage changes caused by large-scale switch switching in power supply lines on power supply lines and communication lines. The surge test specifies two waveforms (1.2/50 μs and 10/700 μs for communication waves), with amplitudes ranging from 0.5kV to 4kV, w...
