With the rapid development of the LED market , life assessment has become a focus of emerging lighting applications. Traditional thermal management faces a major challenge: traditional temperature testing is not suitable for testing all luminaires, which is an urgent need to establish an effective and fast life assessment method to support and promote the development of the LED industry. Gui Dao, president and professor of Guilin University of Electronic Technology, made a report entitled "Rapid Detection of LED Lamp Life: Accelerated Test of Step Pressure" at the 2012 China International Semiconductor Lighting Forum. The semiconductor industry usually has a reliability test method: continuous acceleration. test. However, this test is not very suitable for high reliability products, so step pressure acceleration test must be designed to reduce test time. Professor Yang Daoguo proposed step pressure accelerated test has several advantages: for long-life products, short test time, test a small sample, showing the potential of LED product reliability test applications, followed by step pressure accelerated testing of LED product research, in Some preliminary results were obtained based on the design experiment. Based on the results of this experiment, it can be concluded that the fast life assessment method is applicable to LED products. Reliability testing has many challenges because of internal testing and longevity. The step pressure acceleration test is an effective method. At present, preliminary tests have been carried out, and it is hoped that the mold can be tested in the future, and more results are expected. When referring to the effectiveness test, Professor Yang Daoguo said that there are several ways to reduce test time and reduce test costs. For example, combining the sub-systems to establish a complete system method, the simulation results are compared with the real results, and it is found that the long-term mechanism at the temperature is changed.
