Description
Technical field
The present invention relates to the LED lighting technology, particularly a kind of LED road lamp energy-saving controller.
Background technology
Along with LED development of technology in recent years, have advantages such as volume is little, power consumption is low, long service life, brightness height, environmental protection because of it, will become best lighting system undoubtedly, substitute conventional road lamp, also be the inexorable trend of development.The LED street lamp is for further energy-conservation at present, usually after zero point at night, the brightness of light fixture is reduced half, both can economize on electricity 50% in the time after midnight, but the vehicle in the small hours travels down is few, even long time just has vehicle to cross at interval, in this case, though taked to reduce the measure of brightness, but it is that few car lighting remains a kind of greatly waste that all street lamps are all being opened, if small hours is closed street lamp, can vehicle and the pedestrian at night running be brought inconvenience again.
Summary of the invention
The object of the present invention is to provide a kind of LED road lamp energy-saving controller, it is core with the single-chip microcomputer, be provided with light-operated, acoustic control and clock circuit, can be according to the operating state of the control LED street lamp of environmental aspect intelligence, after midnight in the highway section that does not have vehicle, pedestrian, street lamp is with Temporarily Closed, through out-of-date, street lamp will be opened automatically as vehicles or pedestrians, and vehicles or pedestrians leave way of escape lantern festival and close automatically, the present invention can reduce the power consumption of LED street lamp, more energy-conservation and hommization effectively.
The present invention is achieved by the following technical solutions: LED road lamp energy-saving controller, comprise DC change-over circuit, light-operated circuit, sound control circuit, clock circuit, single-chip microcomputer central control unit, drive circuit and solid-state relay, wherein sound control circuit is provided with 3 above sound transducers.Be divided into two-way after the AC power input, the one tunnel receives the DC change-over circuit, and the input of solid-state relay is received on another road, and the feeder ear of single-chip microcomputer central control unit is received in the output of DC change-over circuit, for single-chip microcomputer and accessory circuit provide working power reliably.The output signal of described light-operated circuit, sound control circuit and clock circuit is received the input of single-chip microcomputer central control unit, the single-chip microcomputer central control unit is provided with five road independent outputs, five tunnel output signals are synchronous fully, one tunnel output signal is received drive circuit, other four tunnel output signals are received the signal input part of two street lamps in adjacent front and two controller for road lamp in back respectively, can four adjacent street lamps of Synchronization Control.Described drive circuit is provided with five inputs, input is accepted the control signal from the single-chip microcomputer central control unit, all the other four inputs are received the signal output part of four adjacent controller for road lamp respectively, in order to accept the control signal of adjacent street lamp, the output of drive circuit is received the control end of solid-state relay, and the output of solid-state relay is received high-power LED street lamp.
Daytime, LED road lamp energy-saving controller is operated in light-operated standby mode, to the dusk time-division, when the light-sensitive element of above-mentioned light-operated circuit detects illuminance＜10 luxs, will send the signal of turning on light to the single-chip microcomputer central control unit, after the single-chip microcomputer central control unit is received signal, to drive circuit output high level, the conducting of drive circuit control solid-state relay, the LED street lamp is opened.
Above-mentioned clock circuit, when clock is gone to zero point at midnight, the single-chip microcomputer central control unit is sent the energy saver mode run signal, after the single-chip microcomputer central control unit is received signal, to the drive circuit output low level, drive circuit control solid-state relay disconnects, street lamp cuts out and starts sound control circuit simultaneously, street lamp enters the acoustic control illumination condition, this moment is if there is the vehicles or pedestrians process, after sound control circuit detects sound, pass to the single-chip microcomputer central control unit, the single-chip microcomputer central control unit sends the signal of turning on light, and street lamp opens and cuts out after 10 seconds of delaying time, if sound control circuit detects sound again in the process of the bright lamp of time-delay, the single-chip microcomputer central control unit can be from newly sending the signal of turning on light, and the delay circuit meeting reclocking of single-chip microcomputer central control unit inside was both delayed time for 10 seconds again, just sound control circuit detect behind the last sound street lamp also can bright 10 seconds, can before vehicles or pedestrians leave this highway section, not cause street lamp to close in advance like this.
In morning next day, light brightens gradually, when described light-operated circuit detects illuminance＞10 luxs, will send the single-chip microcomputer central control unit and interrupt the energy saver mode run signal, after the single-chip microcomputer central control unit is received signal, close sound control circuit, from newly getting back to light-operated standby mode.
For further realizing purpose of the present invention, also adopted following technology, when street lamp moves under energy saver mode, if pedestrian or vehicle are arranged through this highway section, after sound control circuit detects sound, if the street lamp of unlocking vehicle or pedestrian position only, because the illumination zone of single street lamp is limited, can influence pedestrian or vehicle drive personnel's sight line, especially Vehicle Speed is very fast, to the visual field require farther, for avoiding the problems referred to above, after sound control circuit detects sound, five tunnel output signals of single-chip microcomputer central control unit are exported high level synchronously, when opening the proper value street lamp, two street lamps of proper value street lamp front are opened the expansion illumination zone synchronously with two street lamps of back.
