LED lamp universal need to solve many problems

　　LED will become the next generation of energy saving fluorescent lights, but now the national annual production of several one hundred thousand at most, LED lamp, and most of the export and domestic use very few , in fact, the main problem is the price of an ordinary fluorescent lamps light more than ten dollars to get, and a LED fluorescent tube have hundreds of blocks. So now mainly commercial fluorescent tube lighting based. Because commercial lighting more will take into account energy saving, environmental protection , image, government support.

　　But now LED fluorescent products of varying quality , and some are even smaller than the fluorescent lifetime , but useless , as users increasingly deep understanding of LED lamp products , LED lamp manufacturers also need to address the following questions :

　　First . Drive power constant current driver problems. Currently, most large are the total constant current source ( that is, a plurality of parallel light strings share a constant current source, because the resistance of the differences between the LED lamp beads, so different from the current size of each string of lights , any one LED lamp fails, the other will affect the current string lights , so that a large current is more serious light string light fades , will greatly reduce its life short. )

　　Second . Heat. This is one of the core issues of life LED fluorescent tube . Due to the current manufacturers mostly follow suit with built-in power supply , directly can replace the fluorescent tube holder , so your heat power emitted throughout and heat LED itself is distributed in an aluminum casing on the heat , and in fluorescent tubes , so how to deal with the heat ?

　　Third Power supply module electrolytic capacitors life issues ? Even if we use the long life electrolytic capacitors , in the case of high temperature , its life can not be balanced with the LED life. But how to provide a good working temperature to achieve the best life ?

　　Fourth . Question instability and product safety certification of the power supply module can be passed ? Most manufacturers currently on the market uses a high-pressure , non-isolated solutions , and high- back days off power scheme , because the built-in volume is very limited ( to put the lamp ) , it is generally in the design , it is difficult to achieve the power stable. Currently each country and the safety certification are more stringent safety certification for high- voltage power supply is more difficult to pass.
