Abstract

The utility model discloses a residential building solar cell illumination system, which comprises a solar cell (1), an inverter (2), air switches (3), a direct current constant-voltage power supply device (4), automatic control switches (5), switches (7) and a storage battery (8). The residential building solar cell illumination system has the solar cell (1) independent of a power grid and makes adopted LED direct current low-voltage illumination lamps (6) powered in a direct-current low-voltage indirect way. In the daytime, the solar cell (1) indirectly supplies power to the LED direct current low-voltage illumination lamps (6) in residential buildings and charges the storage battery (8). At night, the power is automatically supplied through the storage battery (8). In this way, the residential building solar cell illumination system is formed. One-time low investment is realized. Compared with the power supply means through the power grid, the system is more economic and safer. Even if the power is off due to various reasons, the system usually can keep normal illumination. The system is thus easy to popularize.

Description

Residential building solar cell illuminator

Technical field

The utility model relates to a kind of residential building 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 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 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, though some developed countries 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 normal illumination in the ordinary course of things, the residential building solar cell illuminator that is easy to promote.

For achieving the above object, residential building 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 residential building 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 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 the 220V alternating current through inverter, man of resident family to corresponding unit from the top layer to the ground floor powers, the rated output power of inverter is greater than the rated power sum of confession 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 behind the each household dwelling house, the outlet of air switch connects the inlet wire of dc constant voltage charger, 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 man of resident family.

Described residential building solar cell illuminator, solar cell is controlled to the LED dc low-voltage lighting power supply of man of resident family and to charge in batteries through inverter, air switch, dc constant voltage charger, automatic control switch daytime, then changes automatically evening by the LED dc low-voltage lighting power supply of storage battery to man of resident family.

Described residential building 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 man of resident family.

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

Because residential building solar cell illuminator of the present utility model, 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 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, than more economical by mains supply, man of resident family constant voltage charger is output as the dc low-voltage safe voltage in addition, and 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 of a variety of causes power failure, still can guarantee normal illumination generally speaking, the purpose that is easy to promote.
