Multi-story solar cell illuminator

Technical field

The utility model relates to a kind of multi-story solar cell illuminator

Background technology

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

The utility model content

It is few that the purpose of this utility model provides a kind of one-time investment, more economical more safer than mains supply, even because a variety of causes causes power failure, still can guarantee unit normal illuminations such as school, office, factory, market, hotel, the multi-story solar cell illuminator that is easy to promote in the ordinary course of things.

For achieving the above object, multi-story solar cell illuminator of the present utility model, 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 the electrical network powers to the LED dc low-voltage lighting that adopts 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 the 220V alternating current through inverter, from the top layer to the ground floor to the power supply of each lighting unit, the rated output power of inverter is greater than the rated power sum of the whole LED dc low-voltage lightings of supply, 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 behind each floor, the outlet of air switch connects the inlet wire of the dc constant voltage charger of each lighting unit respectively, the 220V alternating current converts the output of constant voltage direct current to through the dc constant voltage charger, through the LED dc low-voltage lighting power supply of automatic control switch control to this lighting unit.

Described multi-story solar cell illuminator, solar cell daytime through inverter, air switch, dc constant voltage charger, automatic control switch control to the LED dc low-voltage lighting power supply of each lighting unit and to charge in batteries, then change automatically evening by storage battery to the LED dc low-voltage lighting power supply of lighting unit.

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

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

Because multi-story solar cell illuminator of the present utility model, only need school, office, factory, the market, the LED dc low-voltage lighting power supply of 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 select the solar cell of smaller power for use, the price of solar cell is 4～5 yuan/watt at present, so it is fewer at interior one-time investment to contain solar cell and storage battery etc., through about 2 years of budget with regard to recoverable investment, solar battery life is 20 years, the period that is equivalent to thereafter is not need the flower electricity charge basically, than more economical by mains supply, school in addition, office, factory, the market, whole constant voltage chargers of units such as hotel are output as the dc low-voltage safe voltage, light fixture is LED dc low-voltage lighting, thereby electricity consumption is safer, even and because of earthquake, disaster caused by a windstorm, reasons such as ice damage cause grid power blackout still can guarantee normal illumination generally speaking, thereby realized that one-time investment is few, more economical more safer than mains supply, even because a variety of causes has a power failure, still can guarantee school generally speaking, office, factory, the market, unit normal illuminations such as hotel, the purpose that is easy to promote.
