The power of LED Street Light is the highest efficiency switch power in the world, whose efficiency is as high as 95%. With high reliability and long life time, it is suitable for IP67 waterproof rate. In the recent years, it is applied to big power fixtures, such as LED Street Light, LED Tunnel Light. The aluminum shell of package has a good effect of heat dissipation.
How to pick up the right power is most essential for normal operation of mechanical equipment and electronic control system. We need to carefully consider many aspects during selecting the power of LED Street Light. If you want to choose the desirable power, the first step is to know more about it.
LED switch power is controlled by switch tube in circuit. The working principle is to convert direct current into high frequency alternating current to make convertor transform voltage so as to produce required voltage, because the efficiency of high frequency alternating current is higher than electric supply in the circuit of convertor, about 50Hz or 60Hz. Therefore, the switch power of convertor is small in volume and it is not very hot during working. What’s more, the price is lower than the power with direct current voltage. If it is not converted 50Hz or 60Hz into high frequency electric, the switch power is meaningless. Generally speaking, switch power is divided into isolation and non-isolation. The first one must have switch power convertor while the second is not necessary. Compared with traditional direct current power, switch power features on small volume, light weight and high efficiency.
