Method for detecting design defects of driving power supplies

Abstract

The invention is suitable for the field of tests of driving power supplies and provides a method for detecting welding defects of driving power supplies. The method comprises the following steps: placing the driving power supplies in a thermal shock tester, setting a first condition for a temperature shock test and carrying out the temperature shock test on the driving power supplies to detect whether the driving power supplies have design defects; placing the driving power supplies which are in working state in a constant-temperature constant-humidity box, setting a second test condition for a high-temperature high-humidity test and carrying out the high-temperature high-humidity test on the driving power supplies to detect whether the driving power supplies have design defects; screening the driving power supplies with design defects and retaining the driving power supplies without design defects so as to ensure that the detected driving power supplies can normally work for a long time.

Description

technical field [0001] The invention belongs to the testing field of driving power, and in particular relates to a method for detecting design defects of driving power. Background technique [0002] Driving power has been widely used in the field of lamps, and as an important electronic component, it plays a key role especially in various LED lamps. [0003] Due to the influence of working environment, usage habits and other factors, due to design defects, after long-term use of the drive power supply, the electronic components contained in it may be abnormally damaged, which eventually leads to the failure of the drive power supply to work normally. [0004] In the design stage, how to expose potential design defects of the driving power supply and effectively correct the design defects has become the main task of improving the reliability of the driving power supply. At present, the design defects of the driving power supply can only be found through conventional appearan...
