Abstract

The invention discloses an alternating current power regulator suitable for time-interval dimming, an operating method and a street lamp. The alternating current power regulator comprises a power converting circuit and a driving control unit suitable for collecting input mains supply cycle, wherein a clock module is arranged in the driving control unit; the driving control unit is suitable for controlling circuit commutation according to the main supply cycle through the power converting circuit and controlling the output voltage of the power converting circuit according to time interval, so as to realize time-interval dimming control. Aiming at the problems of the existing products on the market currently and the phenomena of poor reliability and short service life, the alternating current power regulator realizes alternating current voltage reduction and regulation control in a time-interval way, so as to solve street lamp intelligent time-interval dimming control, can obviously improve the system reliability and stability, achieves the purpose of increasing the overall service life of a system, and finally achieves the purpose of stabilizing street lamp illumination and reducing electrical energy consumption.

Description

technical field [0001] The invention belongs to the field of electric power conversion or electric power electronics. By adjusting the power supply voltage of the street lamp in time, the intelligent adjustment of the brightness of the street lamp is achieved, and finally the purpose of saving electric energy consumption is achieved. Background technique [0002] In the prior art, most street lamps are turned on at sunset and turned on at sunrise, and intelligent control of time-sharing brightness has not been realized. The traditional time-sharing control is to adjust the input voltage of the street lamp through the time relay to adjust the tap of the transformer to adjust the brightness of the street lamp. With the development of semiconductor switch technology, the market has gradually appeared to realize the intelligence of the street lamp through the control of semiconductor devices such as IGBT. Control, and ultimately achieve the purpose of saving energy. [0003] Th...
