Description

Multi-story solar cell illuminator

Technical field

The present invention relates to a kind of multi-story solar cell illuminator

Background technology

It is longer that solar cell has the life-span as a kind of environmental protection new forms of energy, be not subject to the advantages such as regional limits, but at mains supply, very universal (China accomplishes that village of village is logical substantially, logical in every family), direct current with solar cell converts alternating current to for school through inverter, office, factory, market, whole power consumption equipments of the units such as hotel, electrical equipment and electric consumption on lighting, not only disposable input is too high, need within many years, just can recoup capital outlay, from economical and easily angle can not show a candle to employing mains supply, this is not obviously a selection that reality is feasible, so this pattern is in the world also just for some exemplary engineerings, even if some developed countries are energetically from policy, fund aspect is helped and is also difficult to promote.

Summary of the invention

The object of this invention is to provide a kind of one-time investment few, more economical more safer than mains supply, even because a variety of causes causes power failure, still can ensure in the ordinary course of things the unit normal illuminations such as school, office, factory, market, hotel, be easy to the multi-story solar cell illuminator of promoting.

For achieving the above object, multi-story solar cell illuminator of the present invention, include solar cell, inverter, air switch, DC constant voltage charger, automatic control switch, switch and accumulator jar, described multi-story solar cell illuminator, its solar cell is independent of outside electrical network powers to the LED DC low-voltage lighting adopting indirectly with DC low-voltage.

Described multi-story solar cell illuminator, solar cell connects the input of inverter with DC low-voltage output, convert the direct current of solar cell to 220V alternating current through inverter, from top layer to ground floor to the power supply of each lighting unit, the rated output power of inverter is greater than the rated power sum of supplied whole LED DC low-voltage lightings, and the rated power of solar cell is more than or equal to the rated output power of inverter.

Described multi-story solar cell illuminator, the output line of the 220V alternating current of inverter output enters the inlet wire that connects air switch after each floor, the outlet of air switch connects respectively the inlet wire of the DC constant voltage charger of each lighting unit, 220V alternating current converts the output of constant voltage direct current to through DC constant voltage charger, the LED DC low-voltage lighting power supply through automatic control switch control to this lighting unit.

Described multi-story solar cell illuminator, solar cell is powered and to charge in batteries, automatically turns evening by storage battery and power to the LED DC low-voltage lighting of be with lighting unit to the LED DC low-voltage lighting of each lighting unit through inverter, air switch, DC constant voltage charger, automatic control switch control daytime.

Described multi-story solar cell illuminator, the rated power of DC constant voltage charger is greater than the rated power sum of the LED DC low-voltage lighting of be with lighting unit.

Described multi-story solar cell illuminator, every LED DC low-voltage lighting of its each lighting unit is in parallel mutually, and respectively has switch independently to control.

Due to multi-story solar cell illuminator of the present invention, only need be to school, office, factory, market, the LED DC low-voltage lighting power supply of the units such as hotel, and the power consumption equipment of the unit's of accounting for electricity consumption overwhelming majority, electrical equipment is still by mains supply, thereby only need the solar cell of selection of small power, the price of solar cell is 4～5 yuan/watt at present, so fewer at interior one-time investment containing solar cell and storage battery etc., through budget approximately two years, with regard to recoverable investment, solar battery life was 20 years, and the period being equivalent to is thereafter not need the flower electricity charge substantially, than more economical by mains supply, another school, office, factory, market, whole constant voltage chargers of the units such as hotel are output as DC low-voltage safe voltage, and light fixture is LED DC low-voltage lighting, thereby electricity consumption is safer, even and because of earthquake, disaster caused by a windstorm, the reasons such as ice damage cause grid power blackout generally still can ensure normal illumination, thereby it is few to have realized one-time investment, more economical more safer than mains supply, even because a variety of causes has a power failure, generally still can ensure school, office, factory, market, the unit normal illuminations such as hotel, are easy to the object of promoting.

Brief description of the drawings

Below in conjunction with drawings and Examples, multi-story solar cell illuminator of the present invention is further described.

Accompanying drawing is the circuit theory diagrams of multi-story solar cell illuminator of the present invention;
