But the road lamp system of wind light mutual complementing one class (comprising wind powered street lamp, solar street light, wind and light complementary road lamp etc.), the following defective of ubiquity:

1, owing to the restriction of accumulator capacity, its system power can not be very big, generally is difficult to accomplish more than the 100W, therefore has significant limitation;

2, wind-force or sunlight are not enough influence generating owing to climatic factor such as overcast and rainy causes, discharged or defective battery as a result, and the street lamp cisco unity malfunction, if consider this factor, just must the increasing accumulator capacity, cause the cost increase;

3, the accumulator cell charging and discharging number of times is limited, has just surpassed service life substantially in operate as normal about 3 years, must more renew, and not only increases equipment cost, also increases the manual maintenance cost;

4, the battery after the replacing may cause environmental pollution because of the recovery problem;

5, novel energy (wind energy or solar energy) sends direct current; be stored in the battery in the chemical energy mode through transforming; during use; this chemical energy is again through once conversion; could power to electrical appliance; owing to battery overcharges, crosses and put protection and secondary transfer problem, therefore, the utilization ratio of electric energy is very low in this process.

Large-scale wind generating factory, photovoltaic power plant, not only floor space is big, input cost is high, and troublesome maintenance, addressing difficulty.

The utility model content

At the weak point that exists in the above-mentioned technology, the utility model provides a kind of realization to generate electricity by way of merging two or more grid systems, and saves the intelligent road-lamp of the energy, raising energy utilization rate.

For achieving the above object, the utility model provides a kind of intelligent road-lamp, comprise lamp stand, light fixture, also comprise inverter and energy resource collecting device, described energy resource collecting device is arranged at described lamp stand upper end, described inverter is arranged in the housing of described lamp stand lower end, and described inverter is connected with distribution box by power transmission line, and described distribution box is connected with intelligent net-connected controller.

Described energy resource collecting device be solar battery group or wind-driven generator one of them, or the combination of described solar battery group and described wind-driven generator.

Described intelligent net-connected controller is connected with national grid.

Described solar battery group one group or the multiple solar cell that one or more pieces solar panels, monocrystalline silicon or polysilicon constitute of serving as reasons.

Described wind-driven generator be vane type, vertical axis, circle, spiral in any one.

Compared with prior art, the utlity model has following advantage:

The intelligent road-lamp that the utility model provides makes full use of the lamp stand of traditional common street lamp, makes it have the function of the effect of viewing and admiring and the generating of urban look by day; Utilize wind energy, solar electrical energy generation, the alternating current that the direct current of 12V, 24V, 36V, 48V is converted to 220V, 380V is connected to the grid, additional income, repayment society; Compare with wind powered street lamp, solar street light, wind and light complementary road lamp, the present invention only needs an electric energy conversion, improves generating efficiency more than 50%; Making generated energy surpass power consumption becomes possibility, can realize street lighting zero power consumption, even can be by the money-making of generating electricity by way of merging two or more grid systems, additional income; Grid-connected system does not need additionally to increase transmission cable, uses the mains-supplied circuit to get final product; Suitably reduce because of setting up the land seizure that special wind power plant or photovoltaic generation factory cause, the resource of protecting farmland.

The utility model can improve the lamp stand utilization rate on daytime, can utilize the novel energy generating again.Only need to convert direct current to the alternating current identical with mains frequency, comparing wind light mutual complementing one class street lamp needs through multiple conversions, and this device generating efficiency is higher, and generated energy may surpass power consumption, and street lamp illumination system is equivalent to zero power consumption, even can also extra earning.In the new forms of energy illuminator, break through the accumulator capacity restriction, realized that small power generation system and national grid generate electricity by way of merging two or more grid systems, reach the purpose of energy-conservation, consumption reduction, environmental protection, have very high economic benefit and social benefit.
