LED street lamp driving circuit and LED street lamp control system

Abstract

The invention belongs to the circuit electric technical field and relates to an LED street lamp driving circuit and an LED street lamp control system. The LED lamp driving circuit includes a pulse signal output circuit and a power control circuit; the pulse signal output circuit is electrically connected with the power control circuit; and the power control circuit is used for controlling the pulse signal output circuit to output a plurality of pulse signals with different power. According to the LED lamp driving circuit, the output power of the pulse signal output circuit is controlled through the power control circuit, so that the power of load LED street lamps can be controlled; since the power of the LED street lamps can be different, the brightness of the LED street lamps are different; and therefore, the brightness of the LED street lamps can be controlled.

Description

technical field [0001] The invention relates to the technical field of electric circuits, in particular to an LED street lamp driving circuit and an LED street lamp control system. Background technique [0002] Most of the current roads cannot adjust the brightness when they are in use. This kind of street light is generally turned on when the natural light (sunlight) cannot meet the lighting demand, and then turned off when the natural light can meet the lighting demand or after being turned on for a certain period of time (maybe lasting several hours). [0003] But in fact, as the brightness of the natural light around the street lamp changes, or as the flow of people on the road changes, the brightness of the street lamp does not need to maintain the maximum brightness all the time. For example, in the evening, due to the existence of natural light, if the light of the street lamp is too dark, it cannot play the role of lighting; at night, because the natural light has b...

Problems solved by technology

For example, in the evening, due to the existence of natural light, if the light of the street lamp is too dark, it cannot play the role of lighting; at night, because the natural light has basically disappeared, the street lamp needs a higher brightness to meet the lighting demand; In the middle of the night (such as 3-5 in the morning), there are very few pedestrians on the road (except for the more prosperous roads, basically there are almost no pedestrians), and there is no need for street lights to maintain a higher brightness. Too bright street lights will cause power consumption. waste of

[0004] Therefore, because the brightness of the current street lamp cannot be adjusted, it will always maintain the same brightness from being turned on until it is turned off, and the higher the brightness of the street lamp, the more power it consumes.

This kind of street light that is always on has caused a waste of electric energy
