Intelligent street lamp demand-based illumination control method

Abstract

The invention discloses an intelligent street lamp demand-based illumination control method. According to the method, an active PFC (power factor correction) technology is adopted for correcting power factors, the variable-frequency power control technology is utilized, two kinds of trimming output modes including a remote trimming mode and an independent trimming mode are used, the multi-period trimming output is adopted, and the street lamp demand-based illumination goal is reached. The method provided by the invention has the advantages that the power factor of a street lamp can reach higher than 0.97 under the condition that the electric network voltage fluctuation range is 120V to 264V, and in addition, the integral energy consumption is reduced by more than 50 percent. The requirements of low carbon and energy saving are met, the standard conforms to the relevant national provisions, and certain popularization values and wide application prospects are realized.

Description

technical field [0001] The invention relates to a method for controlling an energy-saving street lamp, in particular to a method for controlling intelligent street lamp lighting on demand. Background technique [0002] The lighting control system of street lamps and landscape lamps is a complex and diverse system engineering. In recent years, with the large-scale promotion and application of street lamps and landscape lamp lighting control systems in various places, a large amount of electric energy is consumed every day, and its energy consumption problem has increasingly attracted the attention of the society. [0003] At present, the existing street lamp control methods cannot meet the current requirements for energy saving. The performance has the following aspects: First, the lighting brightness is still kept constant on the road with low traffic flow, and the lighting brightness cannot be adjusted according to the demand. The realization of lighting has caused unneces...

Problems solved by technology

[0003] At present, the existing street lamp control methods cannot meet the current requirements for energy saving, and the performance has the following aspects: First, the lighting brightness is still kept constant on the road with low traffic flow, and the lighting brightness cannot be adjusted according to the demand. Realize lighting, resulting in unnecessary waste of energy

Second, the grid voltage fluctuates seriously resulting in high maintenance costs

The lifespan of high-pressure sodium lamps, which account for 80% of the lighting fixtures in the entire lighting industry, is generally 10 to 20 years. However, due to the impact of street lighting circuits on peak periods of residential electricity consumption, the voltage fluctuations are relatively large, so that the lifespan of bulbs generally can only reach 1 year, or even less

Frequent replacement of bulbs keeps maintenance costs high

Third, the method of saving money by turning off the lights at intervals does more harm than good

Many places have saved some electricity bills through this method, but it has caused some road traffic safety accidents
