Utility model content
The technical problem that the utility model solves: road lamp system construction cost and operating cost at ordinary times higher, the especially input of electric energy.
The utility model provides following technical scheme: a kind of Solar Street Lighting System, comprise array, controller, batteries, transducer, street lamp, described array is connected with controller, described controller is connected with transducer, described transducer is connected with street lamp, described batteries is connected with transducer, and described controller connects array and batteries, and described controller comprises DC/DC change-over circuit.Described DC/DC change-over circuit comprises electrical energy inputs, electric capacity, power switch pipe one, power switch pipe two, diode one, diode two, inductance, resistance, electric energy output end, described diode one is connected in series with electrical energy inputs, described power switch pipe one is connected in series with diode two, power switch pipe one and the diode two of described serial connection are in parallel with electrical energy inputs, described power switch pipe two is in parallel with diode two, described power switch pipe two is contrary all the time with the state of power switch pipe one, described resistance is in parallel with electric energy output end, described electric capacity is in parallel with a resistor, described inductance one end is connected with electric capacity, the described inductance other end is connected with power switch one, described electrical energy inputs is connected with array, described electric energy output end is connected with storage battery and street lamp.
By technique scheme, in time having illumination, solar battery array is subject to solar irradiation and produces electric energy, and the energy of generation directly supplies street lamp work, meanwhile, and energy more than needed then accumulators group charging.If when the inadequate street lamp of the energy that solar cell provides uses, it is street lamp energy supply that batteries carries out electric discharge.Particularly night or overcast and rainy in, the energy that solar battery array produces is when can not meet load consumption, and the Power supply street lamp that batteries can store uses.Solar energy power generating has the technology of comparative maturity at present, it has safe and reliable, noiselessness, pollution-free, energy is available anywhere, by region restriction, short without the need to consume fuel, cycle of building a station, without the need to erecting power transmission lines, can easily with the advantage such as building combines, be less than conventional power generation usage and other generation mode.Therefore, solar energy is incorporated into road lamp system, can reduces construction and the operating cost at ordinary times of lamp system, especially the cost of electric energy drops into.
Solar Street Lighting System described in the utility model, wherein, DC/DC change-over circuit is similar to BUCK circuit, difference is, DC/DC translation circuit described in the utility model is a many power switch pipe two, and power switch pipe two is contrary all the time with the state of power switch pipe one, namely power switch pipe one conducting power switch pipe two ends, the conducting of power switch pipe one stop power switching tube two.The benefit of this design to reduce the consumption of power in circuit.When not adding power switch pipe two, during power switch pipe one conducting, solar battery array is charged to batteries by DC/DC change-over circuit or powers to street lamp; When power switch pipe one ends, inductance, diode two, batteries (or street lamp) form loop, and circuit plays the effect of afterflow, and the electric current namely in inductance reduces gradually, at this moment the electric current in circuit all flows through diode two, and this will form larger power consumption.After with the addition of power switch pipe two, when power switch pipe one ends, inductance, power switch pipe two, batteries (or street lamp) form loop, circuit still plays the effect of afterflow, but the electric current now in circuit is not all flow through diode two, most electric current now flows through power switch pipe two, and internal resistance during power switch pipe two conducting is minimum, and on whole circuit, the consumption of power has also just diminished like this.So, the utilance of solar energy can be improved.
As further improvement of the utility model, described DC/DC change-over circuit also comprises storage capacitor, and described storage capacitor is in parallel with electrical energy inputs.Under the input of DC/DC change-over circuit is operated in on-off state, if do not add storage capacitor, then, under the state that solar battery array is operated in off and on, optimum Working can not be in.After adding storage capacitor, when DC/DC change-over circuit power switch pipe disconnects, solar battery array charges to storage capacitor, makes solar battery array be in generating state all the time.
As preferably of the present utility model, described power switch pipe one and power switch pipe two are MOSFET pipe.
