Description

Residential building solar cell illuminator

Technical field

The invention of this reality relates to a kind of residential building 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 the whole household electrical appliance of family and electric consumption on lighting through inverter, not only disposable input is too high, need just can recoup capital outlay for many years, 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 guarantee in the ordinary course of things normal illumination, be easy to the residential building solar cell illuminator of promoting.

For achieving the above object, residential building 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 residential building 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 residential building 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, man of resident family to corresponding unit from top layer to ground floor powers, the rated output power of inverter is greater than the rated power sum of supplied resident family whole LED DC low-voltage lighting, and the rated power of solar cell is more than or equal to the rated output power of inverter.

Described residential building solar cell illuminator, the output line of the 220V alternating current of inverter output enters the inlet wire that connects air switch after each household house, the outlet of air switch connects the inlet wire of DC constant voltage charger, 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 man of resident family.

Described residential building 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 man of resident family to the LED DC low-voltage lighting of man of resident family through inverter, air switch, DC constant voltage charger, automatic control switch control daytime.

Described residential building 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 man of Suo Dai resident family.

Described residential building solar cell illuminator, every LED DC low-voltage lighting of its man of resident family is in parallel mutually, and respectively has switch independently to control.

Due to residential building solar cell illuminator of the present invention, only need to family the power supply of LED DC low-voltage lighting, and the household electrical appliance that account for the household electricity overwhelming majority are 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 is 20 years, the period being equivalent to is thereafter not need the flower electricity charge, than more economical by mains supply, man of another resident family constant voltage charger is output as 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, the reasons such as ice damage cause grid power blackout generally still can guarantee 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 guarantee normal illumination, be easy to the object of promoting.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, residential building solar cell illuminator of the present invention is further described.

Accompanying drawing is the circuit theory diagrams of residential building solar cell illuminator of the present invention;
