Aging is important for electronic products, and guarantee is the last step after product production. After debugging, LED products can improve product stability and ensure the stability of product use. A very important device, but it is used by people in many times and cannot be used as a correct and effective device.
1. The LED emission test is to improve the performance of the product according to the failure rate of the product, that is, the characteristics of the road map and the application goal, but the basis of this method, the life of the LED product that cultivates the mature test basis is long.
2. LED aging methods include constant current aging and constant finger pressure equipment. Constant current means that the current is constant at any time. If there is a frequency problem, it is not a constant current. Constant current aging is the most consistent LED current operating characteristic. , Is the most scientific LED aging method;
3. Overcurrent impact aging is also an aging method used. By using factory water, the current is permanently aging and aging, in order to judge the quality and life expectancy of the LED, it can pick out many faulty LEDs that are often aging and cannot be singled out.
