2014 LED lighting development trend driven demand component

2014 for the LED lighting market, MOV and high surge withstand capacity of the fuse demand will rise. High surge withstand fuses will also be used in the growth of wireless base station infrastructure market. In addition, low impedance, high current PTC will be used in mobile computing lithium-ion battery protection applications, the market will follow the growth of smart phones and tablet PCs.

It is observed that in 2014, whether it is home LED lighting, road LED lighting or commercial LED lighting were a full-blown outbreak. Because LED lighting each high quality basically must be equipped with over-current, over-voltage protection components (such as fuses and MOV) and EMI filter components, so the demand through the voltage and the EMI filter around the protected element is synchronous call. 2014 for the LED lighting market, MOV and high surge withstand capacity of the fuse demand will rise. High surge withstand fuses will also be used in the growth of wireless base station infrastructure market.

In addition, low impedance, high current PTC will be used in mobile computing lithium-ion battery protection applications, the market will follow the growth of smart phones and tablet PCs. The fuse will replace the PTC as the main input power supply overcurrent protection element for every outdoor LED lighting AC terminal must be equipped with an overcurrent protection components, electronic components to prevent inrush current will not lead to the damage of the power line lightning rectifier diode and a back.

Although the overcurrent protection element in front will be equipped with one or several lightning protection components (such as MOV, GDT, TVS or semiconductor arrester), the lightning protection components will release most of the lightning surge current, but there will still be a part of going through the overcurrent protection element to the back of the electronic components. Therefore, the over-current protection element must be able to withstand a high surge current, the surge withstand capacity is very important, because the lightning surge current, the over-current protection element can not be blown. Taking into account the self recovery of PTC can not withstand high current, therefore, the overcurrent protection element can only select the fuse. And in order to ensure that the fuse can withstand lightning surge current, this position needs to have enough i2t or time difference of fuse. In addition, taking into account the volatility or tolerance of AC power, the typical rated withstand voltage of the fuse is as high as 300Vac.
