Introduction:

The reliability of LED systems is dependent not only on the LED itself but also on the LED driver, which regulates power to the LED module. As LED drivers are susceptible to wear and failure over time, an LED Driver Aging Test Rack plays a pivotal role in simulating long-term operation, helping manufacturers assess the durability of their products before they reach the market. The LISUN LEDRACK-100W192P is an advanced solution in this domain, designed to accelerate the aging process of LED drivers in a controlled, efficient manner. This paper will discuss the technical specifications, operational principles, and testing methods associated with this device.

Overview of the LED Driver Aging Process:

LED drivers typically undergo stress testing, which includes temperature cycling, continuous power application, and electrical load simulation. The aging process is essential for identifying early failures, performance degradation, and lifespan estimation. These tests replicate the environmental conditions that the LED driver will face during actual operation, including voltage fluctuations, temperature extremes, and continuous running.

The aging test also checks for the driver’s ability to maintain constant current output, its heat dissipation capacity, and the efficiency of its components over time. These tests are essential for ensuring that LED drivers meet industry standards, such as IEC 61347, UL8750, and other global certification standards.
