The wind light mutual complementing solar street light
Technical field
The utility model relates to a kind of street lamp, particularly relates to a kind of solar energy and wind energy can utilized and powers, and can carry out the street lamp of brightness adjustment control again according to the need for electricity situation.
Background technology
Wind energy, solar energy all are free of contamination, inexhaustible regenerative resources, and at present, small-sized wind-powered electricity generation and solar photoelectric system have obtained Preliminary Applications in China.These two kinds of generation modes respectively have its advantage, but wind energy, solar energy all are unsettled, and the discontinuous energy is used separately, often can't guarantee sufficient stable power supply.
If with both combinations, promptly sunlight is not all right just can utilize wind energy, then utilizes solar energy when the little sunlight of wind is strong, so just can keep sufficient power supply in the long time, and just wind energy and solar energy replenish mutually, and we are referred to as wind light mutual complementing.Wind-light complementary system is applied on the street lamp, is exactly the wind light mutual complementing solar street light.This street lamp automatically to charge in batteries, and can throw light on to light source power supply need throw light on to night the time under the situation of sunshine or wind energy abundance automatically.But in wind-light complementary system, because the electric energy difference that wind-driven generator and solar cell produce is bigger, thus how to control respectively, to guarantee that system coordination and stability are that problem to be solved is arranged.
The utility model content
The technical problems to be solved in the utility model provides a kind of wind light mutual complementing solar street light of stability and high efficiency.

Preferably, described battery and controller are installed in the bottom of lamp stand.
Preferably, described controller comprises charging control circuit and charge/discharge control circuit, and described wind-driven generator, solar cell are connected with battery by charging control circuit; Described light source is connected with battery by charge/discharge control circuit.
Further, also be connected with rectification circuit between described wind-driven generator and the charging control circuit.
Further, also be connected with power control circuit between described light source and the charge/discharge control circuit.
Further, comprise that also people, thing detector are connected with power control circuit.
Further, comprise that also timer is connected with charge/discharge control circuit, power control circuit.
Further, comprise that also light-operated switch is connected with charge/discharge control circuit.
Further, described light-operated switch is a photo controller.
Further, described light-operated switch is the solar cell output voltage detecting circuit.
Compared with prior art, the beneficial effects of the utility model are:
1, integrates solar energy, Wind Power Utilization, can utilize solar cell and wind-driven generator, make two kinds of regenerative resources coordinate, stably be light source power supply charge in batteries.
2, adopt multiple automatic control circuit, control switch, the light and shade of street lamp, reach energy-efficient effect.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model wind light mutual complementing solar street light.
Fig. 2 is a circuit connection diagram of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model wind light mutual complementing solar street light comprises lamp stand 1 and the light source 2 that is installed on the lamp stand, at the top of lamp stand 1 solar cell 3 and wind-driven generator 4 are installed also, also are provided with battery and controller (not shown in figure 1) in the bottom of lamp stand 1.
As shown in Figure 2, wind-driven generator, solar cell and light source all are connected with battery by controller 5.Wherein, controller 5 comprises a charging control circuit and a charge/discharge control circuit, described wind-driven generator, solar cell are connected with battery by charging control circuit, so that the electrical power storage that their are produced is in battery, because the electric energy that wind-driven generator produces may have bigger fluctuation, therefore, also be connected with rectification circuit between wind-driven generator and the charging control circuit.When having enough wind-force in the environment, the fan blade of wind-driven generator rotates, and produces electric energy, and this electric energy again to charge in batteries, for preventing to overcharge, is monitored and regulated by charging control circuit after the rectification circuit rectification; When sunny, when the voltage on the solar cell was enough, solar cell, was monitored and is regulated by charging control circuit for preventing to overcharge charge in batteries.
Light source is connected with battery by power control circuit, charge/discharge control circuit.Comprise that also light-operated switch is connected with charge/discharge control circuit; Comprise that also people, thing detector are connected with power control circuit; Comprise that also timer is connected with charge/discharge control circuit, power control circuit.When the night fell, light-operated switch can be opened street lamp automatically, light-operated switch can adopt the photo controller with sensitization function, also can output voltage detecting circuit be set at the two ends of solar cell, when the output voltage of solar cell is crossed when low, show that the light in the environment is very dark, low voltage signal triggers the street lamp unlatching thus.In addition, also can set the time period that street lamp is opened by timer.For making street lamp run on best electricity-saving state, be provided with power control circuit in the controller again, can regulate the brightness of lamp automatically.For example, when in the dead of night, when no personnel and vehicular movement, light can be adjusted to the darkest automatically on the road; And as people or vehicle near the time, the variation that people, thing detector can this ambient conditions of perception outputs signal to power control circuit, improves the brightness of lamp automatically; After people or vehicle far went a period of time, light can dim again automatically.This function with an automatic light meter on a time period can reach the purpose that makes full use of electric energy.
