Description
Technical field
This utility model belongs to electron controls technology and field of energy-saving technology, is to postpone half bright all light street lamp about a kind of road in scenic area infrared acquisition.
Background technology
Now a lot of parks, visit a park, the road of the public place such as view region, rivers lakeside is assembled with various illuminating street lamp, to facilitate visitor, pedestrian play or view and admire.Every night, the illuminating street lamp of these public places was all turned on, the most very convenient crowded time marquis, but to when visitor in the dead of night is rare or rarely visitor patronizes, again can not be by illuminating street lamp Close All, various illuminating street lamps majority is all that working overnight all through the night, and this results in the biggest waste of the energy.
For overcome park, visit a park, there is the problem of the waste energy in the common street lamp in the public place such as view region, rivers lakeside, this utility model uses pyroelectric infrared transducer the small-signal that receives infrared probe to be amplified, and then drives street lamp.This utility model through kinds of schemes test, compare and analyze, circuit have simple and direct, exempt from debugging feature, only use a small amount of common components and parts to achieve expection purpose.Accomplish pedestrian close to time automatically light street lamp, after pedestrian is away from street lamp one segment distance, street lamp is by gradually transferring half bright state after all light time delay one section to.It has a great difference with general delayed lamp operation principle, does not haves pedestrian and arrives without departing from the delayed lamp time one, and the embarrassing phenomenon that street lamp extinguishes at once, it can effectively save electric power resource.
Road in scenic area infrared acquisition described in the utility model described further below postpones half bright all light street lamp involved necessity, guardian technique content in implementation process.
Utility model content
Goal of the invention and beneficial effect: for overcome park, visit a park, problem that the common street lamp in the public place such as view region, rivers lakeside exists the waste energy, this utility model employing pyroelectric infrared transducer the small-signal receiving infrared probe are amplified, and then drive street lamp.This utility model through kinds of schemes test, compare and analyze, circuit have simple and direct, exempt from debugging feature, only use a small amount of common components and parts to achieve expection purpose.Accomplish pedestrian close to time automatically light street lamp, after pedestrian is away from street lamp one segment distance, street lamp is by gradually transferring half bright state after all light time delay one section to.It has a great difference with general delayed lamp operation principle, does not haves pedestrian and arrives without departing from the delayed lamp time one, and the embarrassing phenomenon that street lamp extinguishes at once, it can effectively save electric power resource.
