Led street lamp design question and answer ( 2) The LED lamp factory with precision constant current power supply

Q: what is the LED street lamp power constant current accuracy answer: it is to measure the stability of the LED street lamp power supply current measurements. Such as steady flow accuracy + / - 10 a Current range of 9 1% said here. 9 - 10. 1A。 Some power constant current precision is uneven in the market now, there are some good production

q: what is the precision of constant current LED street lamp power supply a: this is a kind of measuring method the stability of the LED street lamp power supply current. If the current stability precision is + / - 10 a 1%, means that the current range of 9 at this time. 9 - 10. 1. Some precision constant current power supply on the market at present is uneven, the error of some bad products as high as 8%, seriously affected the efficiency and service life of the led street lamp. According to the general requirements, the steady flow precision of led lights should be controlled within 3%. Power must be fine-tuning production, in order to realize the error of 3%. Due to some factories for price blindly reduce signal lamp post company's spare parts and the production cost, low precision become very poor.
