A Transformation Method of Centralized Power Supply for Outdoor Lighting System

Abstract

The invention provides a transformation method for carrying out centralized power supply on an outdoor lighting system. The method includes the first step of preparing an AC / DC conversion circuit, a spare AC / DC conversion circuit, a centralized controller and the outdoor lighting system, the second step of allowing the input end of the AC / DC conversion circuit to be connected with a mains supply, the third step of allowing the positive pole of the output end of the AC / DC conversion circuit to be connected with a live wire of the outdoor lighting system, allowing the negative pole of the output end of the AC / DC conversion circuit to be connected with a null wire of the outdoor lighting system to provide stable DC voltage for the outdoor lighting system, the fourth step of allowing the spare AC / DC conversion circuit to be connected with the AC / DC conversion circuit in parallel, wherein the spare AC / DC conversion circuit and the AC / DC conversion circuit works alternately, and the fifth step of allowing the centralized controller to be electrically connected with the AC / DC conversion circuit, the spare AC / DC conversion circuit and the outdoor lighting system respectively so as to carry out centralized control on all components. Through the method, the functions of single-lamp control, energy consumption conservation and the like are achieved.

Description

Technical field [0001] The invention relates to the field of outdoor power supply, in particular to a method for transforming an outdoor lighting system for centralized power supply. Background technique [0002] Outdoor lighting systems (such as street lights, landscape lights, etc.) directly use the mains power grid as power supply to provide the power demand required by all loads. Generally, the lights are turned on and off at the same time. However, in different sections and different time periods, there are different requirements for the brightness and switching time of the lights. If all conditions are in accordance with a unified standard, it will inevitably cause a waste of electrical energy. In other words, the disadvantage of the current outdoor lighting system is that it does not have the function of single lamp control. [0003] As we all know, China is a developing country with a large population and relatively insufficient resources. To achieve sustainable economic ...

Problems solved by technology

However, under the premise of meeting the needs of outdoor lighting, it is difficult to achieve energy saving and consumption reduction; unless the supply of energy is reduced and the quality of outdoor lighting is reduced, it is possible to achieve energy saving and consumption reduction. The quality of outdoor lighting is not worth the candle
