In the process of road lighting led street lamp application if the led street lamp power factor correction ( PFC） Block response fast enough wave AC input can promote the output voltage is beyond the normal range will cause led lights flashing light. So only in the process of the led street lamp lighting timely elimination of

in the process of the application of road lighting led street lamp, if the led street lamp power factor correction module response fast enough, fluctuation of ac input will make the output voltage beyond the normal range, which can lead to led lights flashing. Therefore, in the process of led street lamp lighting, only in a timely manner to eliminate exchange fluctuation caused by the led street light flashing, led lights to achieve high quality of road lighting. In order to eliminate the exchange fluctuation caused by the led street lamp flicker problem, in the led street light, in use process need to add some simple circuit in the power factor correction module, in order to improve the response time, eliminate flicker problem. Through add OVE to the PFC modules, led street lamp can be more easily response voltage rise too fast, Especially during startup) 。 If there is no OVE obstruction, if there is no timely response, power factor correction in the output voltage and there will be a gap between feedback control. Because the output voltage to achieve its goals, feedback control is trying to reduce the control values, but because it is too slow, it may produce too much energy. Join OVE function can solve this problem. When the boost voltage exceeds the target, protect the start, power factor correction converter quick response. In the face of a good application in the current road lighting, led street lamp is necessary in a timely manner to eliminate led lights flashing, to ensure that the led street light can achieve high quality of road lighting.
