Abstract

The invention discloses a method and device for obtaining the service life information of an LED drive power supply, and the method comprises the steps: obtaining the limit stress test data of the LEDdrive power supply under the working condition of typical application; recognizing a plurality of key elements of the LED drive power supply and corresponding sensitivity stresses according to the limit stress test data; obtaining all groups of service life test data corresponding to all key elements; obtaining all reliability information corresponding to all key elements according to all groupsof service life test data; and obtaining the service life information of the LED drive power supply under the working condition of typical application according to the reliability information througha competition failure model. The invention also provides a device for obtaining the service life information of the LED drive power supply. According to the invention, the method can accurately obtainthe service life information of the LED drive power supply under the working condition of typical application through the above process. The obtained service information is high in credibility, and can reduce the test consumption in an information obtaining process.

Description

technical field [0001] The invention relates to the technical field of LED testing, in particular to a method and a device for acquiring life information of an LED driving power supply. Background technique [0002] LED products have the advantages of high efficiency, energy saving, green environmental protection, etc., which make the LED industry develop rapidly; at the same time, the reliability of the main LED products, such as LED lighting products, is getting more and more attention. A large number of existing experimental statistics show that the driving power supply of LED lighting products has a high failure rate in the entire LED lighting products, which is the main shortcoming of the entire LED lighting products. Practice has proved that the life information of LED driving power can reflect the reliability of the entire LED lighting product. However, the life of LED driving power is generally longer, and the traditional life evaluation method for LED driving power...
