Abstract
The invention provides an energy-saving device capable of adjusting the brightness of street lamps automatically. The device comprises a human body infrared induction module, a triode switch circuit and a relay drive circuit. The output end of the human body infrared induction module controls connection and disconnection of the triode switch circuit, and furthermore, the relay drive circuit is controlled to drive a relay to close or open. Infrared heat release of a human body is detected through the human body infrared induction module on the device, so that when detecting that a pedestrian walks around a street lamp, the street lamp maintains in a normal brightness range; and while when no pedestrian walks around the street lamp, the energy-saving device can automatically switch a relay switch to a power-saving line, and the brightness of the street lamp is adjusted to half of the normal brightness, such that a very good power resource saving function is achieved, and meanwhile, normal lighting needed by the pedestrians at night is not influenced.
Description
Technical field
The present invention relates to a kind of energy saver of automatic adjustment street lamp brightness, especially one increases street lamp brightness automatically when pedestrian walks close to, and automatically reduces the energy saver of street lamp brightness, belong to application electric technology field when pedestrian far goes.
Background technology
Nowadays the street lamp in streets and lanes is gone on a journey to people and bring great convenience evening, traditional street lamp is all generally the lighting system adopting a kind of constant brightness, namely evening, no matter whether someone walked on pavement, street lamp remains at a fixing brightness, the easy like this significant wastage causing power resource.Therefore, be necessary to design a kind of energy saver that automatically can regulate street lamp brightness, when having pedestrian under street lamp when process, this device can make street lamp remain on normal brightness, passes through to illuminate pedestrains safety; And when in the dead of night time, road there is no pedestrian's process, this device can make street lamp automatically switch to battery saving mode, reduces the half that its brightness is original normal brightness, so both reaches the effect of illumination, also serves energy-conservation effect.
Summary of the invention
The object of this invention is to provide a kind of energy saver of automatic adjustment street lamp brightness, to solve electric energy to be wasted by existing street lamp problem because brightness can not regulate.。
The concrete technical scheme that the present invention takes is as follows:
A kind of energy saver of automatic adjustment street lamp brightness, it is characterized in that: the circuit of this device comprises human body infrared induction module HC-SR501, NPN triode Q1, relay R L1, diode D1 and D2, resistance R1 and R2, wherein 1 pin of human body infrared induction module HC-SR501 connects+5V power supply, one end of 2 pin connecting resistance R1 and R2, 3 pin ground connection, another termination+5V power supply of resistance R1, the base stage of another termination triode Q1 of resistance R2, the grounded emitter of triode Q1, the positive pole of diode D2 and one end of relay R L1 coil access the collector electrode of triode Q1 jointly, the negative pole of diode D2 and the other end of relay R L1 coil connect+5V power supply jointly, one group of normally-open normally-close contact of relay R L1 forms an either-or switch, the fixed contact lead-out wire of either-or switch is as an output of this device, the normally closed moving contact of either-or switch connects the negative pole of diode D1, the positive pole of diode D1 and either-or switch often start another output as this device of the lead-out wire after contact shunt.
Beneficial effect of the present invention is: enter in street lamp lighting loop by two output series connections when this regulates the energy saver of street lamp brightness to use automatically, by the human body infrared induction module on device, infrared human body heat releasing is detected, when having detected that pedestrian walks near street lamp, street lamp maintains normal brightness scope, and when there is no pedestrian near street lamp, this energy saver can automatically switch relay switch to economizing electric line, half when making street lamp brightness be adjusted to normal, this makes it possible to the effect playing saves energy resource well, do not affect the normal illumination needed for pedestrian evening simultaneously yet.
Accompanying drawing explanation
Fig. 1 is that this regulates the circuit diagram of the energy saver of street lamp brightness automatically.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, this regulates the circuit of the energy saver of street lamp brightness to comprise human body infrared induction module HC-SR501 automatically, NPN triode Q1, relay R L1, diode D1 and D2, resistance R1 and R2, wherein 1 pin of human body infrared induction module HC-SR501 connects+5V power supply, one end of 2 pin connecting resistance R1 and R2, 3 pin ground connection, another termination+5V power supply of resistance R1, the base stage of another termination triode Q1 of resistance R2, the grounded emitter of triode Q1, the positive pole of diode D2 and one end of relay R L1 coil access the collector electrode of triode Q1 jointly, the negative pole of diode D2 and the other end of relay R L1 coil connect+5V power supply jointly, one group of normally-open normally-close contact of relay R L1 forms an either-or switch, the fixed contact lead-out wire of either-or switch is as an output of this device, the normally closed moving contact of either-or switch connects the negative pole of diode D1, the positive pole of diode D1 and either-or switch often start another output as this device of the lead-out wire after contact shunt.
Two output series connections enter in street lamp lighting loop when automatically regulating the energy saver of street lamp brightness to use by this, when the human body infrared induction module HC-SR501 on device detects that pedestrian walks near street lamp, its 2 pin exports high level, triode Q1 conducting, relay R L1 adhesive, the either-or switch of relay R L1 switches to the circuit not connecting diode D1, street lamp L1 maintains normal brightness scope, and when human body infrared induction module HC-SR501 detect there is no pedestrian near street lamp time, its 2 pin output low level, triode Q1 ends, relay R L1 discharges, the either-or switch of relay R L1 switches to the circuit connecting diode D1, half when making street lamp L1 brightness regulation be normal, this makes it possible to the effect playing saves energy resource well, do not affect the normal illumination needed for pedestrian evening simultaneously yet.
