Importance of Aging Test in LED high bay lightings

Time:2015-10-07 Views:2717 Compile:SUNPER

There are some problems that we come across regularly in the application of the LED high bay lightings. Most of the LED high bay lights usually work properly especially when they are still new. However, after a period of time the lightings start to have dim lights, some faults, flashing, intermittent light as well as many other phenomena. All these changes are seen as the products continue to be used for long and they keep on becoming bigger and bigger. This poses some dangers since they may cause serious damages to the products. The main causes of this phenomenon include the following.

 

The first one is that the production of the LED high bay lightings as well as soldering process requires welding temperatures are usually too high. The time needed for welding is also too long and hence the work of anti-static is not done. These issues normally contribute up to 95 percent in the entire process. 


The second cause of this phenomenon is the fact that the LED chip itself results to the production process. The best thing about all this is that there are solutions used to solve it. To just highlight them they include taking good control of the welding process and the other one is the aging test after the production.

 


Below are some of the importance as well as details to know concerning the two solutions to solve the phenomenon mentioned above.

 

The aging test is very essential in ensuring the reliability of the LED high bay lightings. This is normally the last most important step during the production of the LED high bay lightings. This test can be used to improve the performance of the LED high bay lightings as well as to improve the total effectiveness plus stability. It is very crucial part of the LED high bay lightings quality. However, it is usually ignored in most of the cases as an effective way. This aging test is basically based on the product’s fault countermeasure curve which is a property of the bathtub curve taken so as to improve the reliability of this product. However, this method is not really required due to the expense of a single LED chip life.

 

The LED high bay lightings aging modes include constant current aging and constant voltage. The constant current means that at any time the current should be constant. The pulsating current or AC current can be designed to RMS which is constant. Aging is the most constant LED current operating features and is also the most scientific way. Aging here means the impact due to over-current. The adjustable frequency and current can now be used to lengthen the short life expectancy of the LED.

 

The SUNPER has more than 24 hours aging test which they do carry out before packaging and shipping their LED high bay lightings. This is done to ensure that customers receive high quality products. Therefore, the aging test is an integral part in all the production processes carried out by the SUNPER. However, they cannot guarantee 100 percent efficiency since there is always an error. However, they are trying all they can to solve this error within the shortest time possible.
