What is the LED aging test, and why is it so important?

Putting LEDs through an LED aging test is crucial in ensuring that they will last if promised. The purpose of an aging test on lighting components is to detect flaws in the product and evaluate how well it holds up to extreme conditions. For led lighting goods to be of high quality and have a low failure rate, aging tests must be accurate and reliable.

It’s a reliability test to ensure the LED product meets international requirements. In addition to improving the LED product’s performance and stability, this rigorous testing also has other advantages.
When an LED product breaks, it’s typically because of one of two things: the welding method (incorrect welding temperature, excessive soldering time), or the quality of the LED.

LED aging test or running the LED light fixture on power for an extended time to see how it performs thermally and functionally. During a thorough ageing test, it can only find failures in the power supply, the LED PCB board’s soldering, or even a greater operating temperature than expected.

Why it is necessary?
It is common knowledge that the longevity and dependability of LED goods are the most crucial features. The potential life of an LED is quite long; depending on the usage circumstances and the driving current, an LED may last for 50,000 hours or more.

However, in the first stages of its usage, LEDs will experience some light fading due to their own performance. Dimmable light and flashing may result from the lack of material quality or lack of manufacturing standardization in our LED goods. Due to failure, flickering, and other problems, LED bulbs to have a shorter lifespan than planned.

For this reason, testing the longevity of LED goods requires an LED aging test, which is also required for effective quality control over the breakdown of welding packaging components. Technologies such as online monitoring of driving power supply and product current, voltage change, and more are used in this aging process.

Temperature-adaptive testing, analogue voltage range (high, medium, low) testing, impact destructive testing, and other technologies are also used.
There is no way to ensure the product’s quality without an aging process; any moment after the first use, it might break. The manufacturer will incur substantial additional expenses as a result. In contrast, the product’s efficacy as a light or lantern has been enhanced by expert age, and the product’s durability has been considerably enhanced, which will undoubtedly result in fewer customer complaints and a higher quality reputation.

As a professional LED lighting manufacturer, LISUN always do the 100% aging test before our products are packaged. The problem products will stay in the factory, and products without problems will sell to users to ensure that the products that users buy are reliable or less problematic.
