Energy-saving soft start street lamp control system

Abstract

The invention discloses an energy-saving soft start street lamp control system, which comprises an alternating current power supply, at least one lighting lamp, a phototriode, a first load control module and a first soft start module, wherein the at least one lighting lamp is connected to an alternating current circuit in parallel; a collector electrode of the phototriode is connected with a live wire input end of the alternating current power supply through a current-limiting resistor, and an emitter electrode of the phototriode is grounded; a diode is arranged on a live wire between the phototriode and the lighting lamp; an active load series end and a driven load series end of the first load control module and a zero wire connecting end of the alternating current power supply are respectively connected with the lighting lamp, a live wire and a zero wire; the first soft start module is connected between the driven load series end of the first load control module and the live wire of the alternating current power supply; the first soft start module comprises a contactor and a time delay part which can be used for controlling the contactor to closed in a time-delaying way; and normally open contacts of the contactor are connected to two ends of the diode in parallel. According to the invention, energy saving and soft start of the street lamps can be realized by arrangement of the phototriode and state matching between the diode and the normally open contacts of the contactor.

Description

technical field [0001] The invention relates to the technical field of street lamp control, in particular to an energy-saving soft-start street lamp control system, in particular to a system that can automatically turn on and off a street lamp according to the brightness and darkness of natural light, and the lamp head can gradually light up when it is automatically turned on Street light control system. Background technique [0002] At present, lighting power saving is listed as another major power saving project besides power saving. The public lighting street lamps on urban roads are controlled by the power supply department to turn them on and off at regular intervals. The lighting brightness is high, and during the period from midnight to dawn, the vehicles are scarce and the flow of people is greatly reduced, so the required lighting brightness is low. If the street lights are still illuminated like the first midnight, it will cause unnecessary waste of electric energy...

Problems solved by technology

[0002] At present, lighting power saving is listed as another major power saving project besides power saving. The public lighting street lamps on urban roads are controlled by the power supply department to turn them on and off at regular intervals. The lighting brightness is high, and during the period from midnight to dawn, the vehicles are scarce and the flow of people is greatly reduced, so the required lighting brightness is low. If the street lights are still illuminated like the first midnight, it will cause unnecessary waste of electric energy

In addition, general street lights will not be turned on during the day. When the road light is insufficient due to bad weather, accidents will easily occur if the street lights are not turned on in time.

[0003] At the same time, at the moment when the street lamp is turned on after the power is turned on, because the street lamp filament has a small resistance when it is cold, the high-voltage filament will generally have a large inrush current at the moment, resulting in a relatively short service life of the street lamp.
