Aging test refers to the test process of simulating various factors that affect the use of the product involved in the actual process and strengthening the corresponding conditions. The most common is the aging test for plastics, and the main methods are light aging, damp heat aging and hot air aging.
LED grow lights are electronic and electrical products. The aging test is different from the aging of plastic materials. The most important thing in the use of LED grow lights is to enable them to be used efficiently and normally, and the factors that affect their normal use are mainly dead light rate, heat dissipation, high efficiency, stability of light emission, etc. The main test methods are done by increasing voltage and current.
The dead light rate test of LED grow lights, generally speaking, after the LED grow lights are produced into finished products, there is no problem in the working room under the rated voltage and current. However, there will inevitably be a short period of high voltage or a sudden power-off on the lights during use. To ensure that the lights can still work normally after this common situation occurs, it is necessary to do a test before the LED grow lights leave the factory, so as to detect whether the power supply configuration is qualified, the welding position is firm, and the assembly wire has a certain bearing capacity.
The heat dissipation performance of LED grow lights is directly related to its service life and the luminous efficiency of lamp beads. The aging test method is to keep the LED plant lights at their maximum temperature within a certain period of time, and its internal structure will not be damaged. And within a certain period of time, the temperature of each component of the LED grow light will not increase with the high intensity working time increased.
LED grow lights have high efficiency and stability. Whether the LED plant grow lights are efficient and stable depends on the rectification and partial voltage capability of the internal power supply. As long as the quality of the power supply is excellent, LED grow lights can guarantee efficient and normal light within its rated service life under normal circumstances. In general, the power supply will be equipped with an overvoltage automatic power-off device, which will not have a serious impact on the lamp beads. However, it is not ruled out that the lamp wafer flaws will occur during the process of encapsulation. Therefore, a flash test is also required to ensure the lights are stable, normal and efficient work.
Generally speaking, the aging test is to test the lights' endurance of various situations that may be encountered in the actual application. The difference is the testing method and testing process.
