In order to eliminate the injustice of the test, many companies are entrusted to a third party to test the LED assembly and circuit structure. LED devices may be tested in the harsh environment, or use a few weeks. During the test, at the same time the pressure, temperature cycling, fixed voltage / change current fixed / change test, test to determine whether the high power uv led suppliers to meet the application requirements in other harsh environmental conditions.
Accelerated life cycle testing is a key test to avoid failure in special applications. The test helps to ensure that screen out those expectations at least for 100,000 hours, but only work 1000 hours in advance of LED failure. This situation may arise because of the low-quality LED will reduce the brightness after 1000 hours of work. In fact, if a lower-quality high power uv led suppliers have a higher drive current, at an early stage is high quality LED light, however, the excessive current causes the LED heat too fast, the end result is the brightness dimmed or burned.
In addition, the assembly technology to some extent on the LED performance than the chip itself is also a big example. The design engineer should ask for the reliability of the specifications of LED to LED suppliers, and the LED assembly and testing to ensure that the relatively high brightness is indeed better. Some excellent led high bay suppliers to ensure the reliability of the LED assembly technology for three years or longer, and can further provide the ultimate LED products, including the appropriate design with high quality LED and for special applications.
