Description
Technical field
The invention belongs to Electric automatic control and power-saving technique field, relate to a kind of park and visit a park close to the bright complete bright LED street lamp of time lagged type half.
Background technology
Along with urban beautification brightening place of working constantly advances, a lot of park, visit a park, the road of the public place such as riverside, along the river view region all installed various illuminating lamp, to facilitate visitor, pedestrian plays or views and admires.Every night, the illuminating lamp of these public places was all opened, really very convenient crowded time marquis, but to when visitor late at night is rare or rarely visitor patronizes, again can not by illuminating lamp Close All, this just causes the energy to waste greatly.
The defect wasted energy is there is for overcoming the common street lamp in above-mentioned place, visit a park and utilize Microwave Scanning control mode close to the bright complete bright LED street lamp of time lagged type half in park of the present invention, it is by human body sensing far distance controlled, accomplish people close to time automatically light LED street lamp, people walks away from after LED street lamp one segment distance, LED street lamp transfers half bright state to automatically by after complete bright time delay one section, and it can conservation of power resource effectively.
Below describe in detail park of the present invention visit a park close to the necessity involved in implementation process of the bright complete bright LED street lamp of time lagged type half, guardian technique content.
Summary of the invention
Goal of the invention and beneficial effect: for overcoming park, visit a park, there is the defect wasted energy in the common street lamp in public place such as riverside, along the river view region, visit a park and utilize Microwave Scanning control mode close to the bright complete bright LED street lamp of time lagged type half in park of the present invention, it is by human body sensing far distance controlled, accomplish people close to time automatically light LED street lamp, people walks away from after LED street lamp one segment distance, LED street lamp transfers half bright state to automatically by after complete bright time delay one section, and it can conservation of power resource effectively.
