Aging test refers to the experimental process of simulating various factors that affect the use of products in real-life situations and reinforcing corresponding conditions. The most common is the aging test for plastics, which includes methods such as light aging, damp-heat aging, and hot air aging.
LED plant light belongs to the category of electronic products. The focus of its aging test is different from that of plastic materials. The main factors affecting the normal use of LED plant growth lights are dead lamp rate, heat dissipation, and stable light efficiency. The main testing methods are completed by increasing voltage and current.
Generally, after the LED plant light is produced, it can work without any problems under the rated voltage and current. However, during use, short high voltages, sudden power outages, and other situations are unavoidable. To ensure that the lamps can still work normally after these common situations occur, testing should be done before the LED plant lights leave the factory to detect whether the power supply configuration is qualified, the welding position is firm, and the assembled wire has a certain bearing capacity.
The heat dissipation performance of LED plant growth lights is directly related to their service life and light efficiency. The aging testing method is to subject the LED plant light to its maximum temperature for a certain period of time, but its internal structure will not be destroyed. In addition, during a certain period of time, the temperature of each component of the LED plant lights will not increase with the prolongation of high-intensity working hours.
The stable and efficient light emission of LED plant lights is mainly affected by the rectification and voltage division capability of the internal power supply. As long as the power supply quality is excellent, the LED plant light can generally ensure high-efficiency and stable light emission within its rated service life. Moreover, most power supplies are equipped with overvoltage automatic power-off devices, which will not cause serious damage to the light chip. However, there is still a possibility of leakage during the LED plant growth light chip sealing process. Therefore, flash testing is also necessary to ensure stable and efficient operation.
The principle of aging testing for LED plant growth lights is the same as other products, which is to test its ability to withstand various situations that may be encountered in actual use. The difference is the testing method and process.
