Abstract The rapid advancement in LED lighting technology has driven the need for precise and reliable testing systems. The LISUN LSRF-3 is a comprehensive testing solution designed to meet the rigorous demands of the LED lighting industry. This paper provides an in-depth analysis of the LSRF-3, focusing on its ability to accurately assess LED start-up, run-up, stabilization, and light flicker per...
With the development of LED technology, LED market is booming, its advantages mainly hinged on its good luminous efficiency, long service life and reliability, favored by the market and consumers. However, due to LED’s fast response speed, and the lack of thermal inertia and afterglow effect of traditional lamps, it is affected by current fluctuations, and current fluctuations will directly ...
A CIE TN006-2016 CIE SVM certified flicker test system. The harmonics and the flicker analyzers use alternating current (AC) sources with peak current ratings of up to 3 seconds and low source impedances. With its dual-processor design and multi-tasking kernel, the system also allows for continuous monitoring and precise measurement in real-time. What is the flicker test? This testing technique is...
LSRF-3 Lamp start, Run-up time and Light Flickering Analyzer – Flicker Tester is equipped with Class A fast photometric probe, so the sampling speed is up to 100kHz. It fully meets the requirement of BASIC, Energy Star V2.1, IEC TR 61547-1:2020 IEC-Pst, CA CEC, ASSIST, CIE TN006-2016 CIE SVM, IEEE Std 1789 standards, etc. It is professional for flicker test of LED lights and lamps, energy-sav...
LISUN’s LSRF-3 Because the LSRF-3 is equipped with a Class A fast photometric probe, the sampling rate can reach 100kHz. It fully complies with BASIC, Energy Star V2.1, IEC-Pst, CA CEC, ASSIST, CIE SVM, IEEE Std 1789, and other standards. It is suitable for testing the flicker of LED lights and lamps, energy-saving lighting, and so on. According to EU directives 1494/2012, 2009/125/EC, EU201...
Flicker Test System also known as stroboscopic still or tachometer, is an optical measuring device that can change a vibrating, high-speed rotating or periodically moving component into a “stationary” component. Flicker Test System itself can emit a short and frequent flash, and its flash speed can be set by the user according to needs. When the flash frequency of the stroboscope is ad...
Introduction Any lamps and lanterns may have “flicker“ when connected to AC power! Unless you don’t use batteries or transformers, lighting fixtures cannot avoid “strobe“, which is common in our lives. What is alternating current? The current increases first in a cycle, then decreases when it reaches the peak value, and when it reaches 0, the power supply continues in...
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 ...
For Windows 7/8 USB driver coding, Microsoft explicitly requires drivers to use EV code signature, and after Windows 10/11, the EV coding signature is not enough but need to submit to Windows Hardware Development Center Dashboard to get Microsoft code signature, or the USB driver can’t be run in the newest Windows 10/11 (see Fig 1) even you Disable Digital Driver Signature Enforcement. Fi...
Application of portable spectroradiometer in the Detection Direction of LED Lighting Fixtures Since the invention of LED lamps, their advantages such as high brightness, low power consumption and long life have quickly won the favor of the lighting market. Nowadays, LED lamps have been popularized in all aspects of our lives. However, more and more people are paying attention to the fact that as a...
On 5th , December, 2019, the European Commission officially announced the new ErP Regulation (EU) 2019/2020 and Energy Efficiency Labelling Regulation (EU) 2019/2015 for lighting products, which will replace the current ErP Regulation (EC) No 244/2009, (EC) ) No 245/2009, (EU) No 1194/2012 and Energy Efficiency Labeling Regulation (EU) No 874/2012. The new regulations have been issued for more th...
LISUN engineers always paying attention to the update of various standards to ensure that LISUN products meet the latest standard requirements. The European Commission formulated the official version of the ecological design regulations (EU)2019/2020 for light sources and separate controller gears on 1 October, 2019. This directive has changed the requirements for flicker testing: 1. Add strobos...
