So the LED street lamp with solar cell for supplying power becomes the optimal selection that roadway illumination and energy saving is transformed.
But the LED street lamp of solar cell for supplying power can not control effectively to the power consumption of LED street lamp at present, overcast and rainy continuously, under the situation of solar powered deficiency, can influence the effective lighting time of LED street lamp.
The utility model content
The purpose of this utility model is to provide a kind of all-weather solar street lamp, and it can under the situation of solar powered deficiency, prolong the effective lighting time of LED street lamp overcast and rainy continuously.
For achieving the above object, the technical solution of the utility model is a kind of all-weather solar street lamp of design, comprises lamp stand, and led light source and solar cell are fixedly arranged on the lamp stand; Solar cell is connected with led light source by photovoltaic controller, first relay, battery, second relay, intelligent converter successively; Battery is connected with the voltage detecting circuit for detection of its voltage; The control end of the pwm signal input of the output of voltage detecting circuit, intelligent converter, first relay and second relay also is connected to Programmable Logic Controller respectively; Programmable Logic Controller also is connected with photovoltaic controller.
Preferably, described Programmable Logic Controller is built-in with the PWM control module.
Preferably, described Programmable Logic Controller is built-in with street lamp working hour control module.
Preferably, described solar cell is fixed in the lamp stand top.
