The improvement of circuit protection technology can prolong the life of LED

Due to the advantages of energy saving, long life and other advantages, LED lighting is gradually replacing incandescent light as the mainstream of the lighting market. Nevertheless, there are still many problems in LED technology. For example, how to improve the performance of each component in order to prolong the life of LED and improve its reliability. The circuit protection is particularly important.

Because the LED power supply and driving circuit is easy to be suffered from electric shock and short circuit fault and damage, so in the driving circuit design should fully consider the protection measures of various fault conditions, in order to improve the reliability of the circuit, to ensure the reliability of the circuit can meet the requirements of long life LED. At present, there are 3 ways to protect the LED circuit: the protection of the LED circuit using the fuse (tube), the use of transient voltage suppression diode, select self recovery fuse. Among them, the first two schemes are more difficult to be applied in practice, and the self recovery fuse is a more satisfactory technical scheme.

In order to explore the industry to provide a better platform for circuit protection scheme, big bit information agencies will be held in Ningbo in May 31st seventh LED general illumination drive technology seminar, the seminar by big bit information organized by the application of semiconductor devices, network host. By then, Shanghai Junyao Electronics Co. Ltd. technical support Zhang Ting will bring titled "circuit protection technology" LED general lighting, for participants to discuss.

LED is a voltage sensitive device, its longevity is based on its safe working environment. Each LED working current should not exceed 20mA, more than too much LED will easily be burned. Through the protection of the LED circuit can effectively improve the reliability of the LED lighting to ensure long life. Therefore, it is a necessary condition for the development of LED industry to find excellent LED circuit protection scheme, which is also one of the important trends in the development of LED industry.
