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...
At present, ErP has issued new regulations (ErP Regulations (EU) 2019/2020 for Lighting Products and Energy Efficiency Labelling Regulations (EU) 2019/2015) on 5th December, 2019. The new regulations have come into effect on 25th December, 2019. That is, from 25th December, 2019, you can apply for the ErP of the new regulations. The new regulations will be enforced on 1st September, 2021. It means...
Almost all types of lamps is easy to flicker, including incandescent lamps, halogen lamps, and even LED bulbs. But the effect of each light is different. For example, in incandescent and halogen lamps, the filament temperature responds slowly to changes in current, so you will not notice the effect of flicker. For current changes, the LED responds almost immediately, so the blinking will be more n...
In recent years, the LED market has been expanding, which is attributed to the unique characteristics of LED solid-state lighting products, such as good luminous efficiency, long service life and high reliability .Therefore, LED solid-state lighting products are increasingly favored by the market and consumers. But at the same time, because of the fast response speed of LED and the lack of thermal...
Due to the LED solid-state lighting products have good luminous efficiency, long life and high reliability unique characteristics, so it’s became more popular by markets and customers. But at the same time, the LED solid lighting have fast response characteristics, it haven’t thermal inertia and afterglow effects, like traditional lamps, so it have big influence by current fluctuations, the cu...
“Bright blind” in life is an exaggerated description of some impact incidents, but if it is used for the LED lighting industry, then it is the quality problems of LED lamp itself. And “strobe” is likely the initiator to lead to “blind”. Many people are not very clear about the concept of strobe, and even don’t care about its harm. Regarding the hazard of strobe, experts have given t...
Many customers need aging LED lamps, but do not have a clear concept of aging test and life test. Aging test usually use aging test racks. What is aging test rack? Aging rack is dedicated to simulate the products in real conditions involved in the use of various factors on the aging of the product conditions to strengthen the process of the corresponding conditions. Why we need aging test? Electro...
The LED stroboscopic effect actually have two concepts: One is strobe which mean the depth of light flux fluctuations, the more violent fluctuation, the depth of strobe more lager. Second is stroboscopic effect which mean the human visual produce negative effects of electric light flicker, the more violent fluctuation, the negative effects more lager, the damage will be more bad. The flicker and s...
