Recent years, as the Gaoyou economic development, making the increase in night work need led high bay, leisure, entertainment and other activities multiplied, vehicles and pedestrians, led street lights tenders, especially the 2010 peak load shifting working hours adjustment, making the light switchtime needs to have some changes.need further improvement.
The main basis is: First,the original light switch test sampling completed within one year, led street lights tenders, affected by the year of individual abnormal weather data acquisition is not universal and representative, there is lit as early as the summer of individual hours, lighting later in the winter individual sessions anomaly; second, the overall time of the lamp needs is a broad, spare themore and more people switch lights time more and more attention, more and moreinfluence. Such as traffic laws will be street lights turn-on time as the reference time ofthe car lights; Gaoyou implement to avoid it after work, led street lights tenders, a considerable part of the morning an hour late to work one hour late at night, making the morning street lights by concern about the decline, the demand for timely lighting at night is more urgent.
Strengthen the time-sharing, partition, hierarchical control, and sound science to promote the middle of the night lights of the control mode.
The middle of the night LED lights off for a row of double street lamps or light fixtures in the rest of the night car few pedestrians, street lights, street lighting in the morning flow recovery after recovery, so that the street light illumination with the needs of the scientific adjustment.
But the middle of the night lights there is a single way, classification unclear drawbacks. The middle of the night lights unified 12:00 midnight extinguished in 90 minutes before the lights of street lamps morning point in time recovery. But in fact in the outer ring, the actual demand for street lighting difference. More scientific and rationalapproach should be more earlier in the more rural areas to close the middle of the nightlights, light up the middle of the night lights later recovery. For example, led street lights tenders, define the trafficdown to a certain value, or reduced to a certain percent of the peak value to close themiddle of the night lights, light up the night light when the traffic is restored to a certainvalue or reach a certain percent of the peak. Clearly more scientific and rational, but require more precise management, and regional economic development will lead tochanges in the reference value, the need for regular adjustments. In order to achieve atrue sense of the time-sharing, partitioning, and hierarchical control.
