Shown here are the results of high-temperature accelerated current tests conducted on the new and conventional white LEDs. In the case of the conventional product, the epoxy resin underwent a change during testing, resulting in a 20% decrease in luminous intensity, while the new product showed virtually no degradation. Under normal conditions, this translates to no significant brightness drop even after ten years, making it ideal for industrial equipment and automotive applications where long-term reliability is required.
