Abstract

The invention discloses a solar cell independent lighting system which comprises a solar cell (1), a storage cell (5), a switch (4) and an automatic control switch (2). The solar cell (1) is independent of a power grid to power an adopted LED direct-current low-voltage lighting lamp (3) in a direct-current low-voltage manner through the automatic control switch (2),to automatically power the LED direct-current low-voltage lighting lamp (3) and charge the storage cell (5) in the daytime through the automatic photoelectric control switch (2) and automatically enable the storage cell (5) to power the LED direct-current low-voltage lighting lamp (3) at night, so that the solar cell independent lighting system is formed, one-time investment is small, higher economical efficiency and more safety are realized when compared with power supply through the power grid, normal household lighting can still be guaranteed generally even during a power failure due to various reasons, and the solar cell independent lighting system is easy to popularize.

Description

Solar cell independent lighting system

Technical field

The invention of this reality relates to a kind of solar cell independent lighting system

Background technology

It is longer that solar cell has the life-span as a kind of environmental protection new forms of energy, is 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, developed country is all the more so) situation under convert alternating current to for the whole household electrical appliance of family and electric consumption on lighting with the direct current of solar cell 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 has a power failure, still can guarantee in the ordinary course of things family's normal illumination, be easy to the solar cell independent lighting system of promoting.

For achieving the above object, solar cell independent lighting system of the present invention, include solar cell, battery, switch and packaging switch, described solar cell independent lighting system, its solar cell is independent of outside electrical network, directly powers to the LED DC low-voltage lighting adopting with low-voltage DC through automatic control switch.

Described solar cell independent lighting system, solar cell is powered to LED DC low-voltage lighting and to charge in batteries, automatically turns evening by battery and power to the LED DC low-voltage lighting of family through automatic control switch control daytime.

Described solar cell independent lighting system, the power of selected solar cell is greater than the rated power sum of the LED DC low-voltage lighting of Suo Dai family.

Described solar cell independent lighting system, its every LED DC low-voltage lighting is in parallel mutually, and respectively has switch independently to control.

Due to solar cell independent lighting system of the present invention only need to family LED DC low-voltage lighting power supply, and the household electrical appliance that account for the household electricity overwhelming majority are still by mains supply, thereby only need select low power solar cell, the price of solar cell is 4～5 yuan/watt at present, so containing solar cell, automatic control switch and battery one-time investment are fewer, 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, another solar cell independent lighting system separates with electrical network, independently powered to the LED DC low-voltage lighting of family with DC low-voltage by solar cell, electricity consumption is safer, even and because of earthquake, tsunami, 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 family's normal illumination, be easy to the object of promoting.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, solar cell independent lighting system of the present invention is further described.

Accompanying drawing is the circuit theory diagrams of the solar cell independent lighting system of the present invention one family family;

1, solar cell 2, automatic control switch 3, LED DC low-voltage lighting 4, switch 5, battery

As shown in the figure: 24V, 100 watts of solar cells 1 connect with

automatic control switch

2, 8, the each room of family LED DC low-voltage lighting 3 (1)～3 (8), after parallel connection, connect with automatic control switch 2, wherein 3 (1), 3 (2) to select rated power be 15 watts of LED low pressure fluorescent tubes, 3 (3)～3 (8) to select rated power be the LED low voltage bulb of 8 watts, 3 (1)～3 (8) rated voltage is 24V, battery 5 also connects with automatic control switch 2, realizing daytime by automatic control switch 2 controls is powered and battery 5 is charged to LED DC low-voltage lighting 3 by solar cell 1, powered to LED DC low-voltage lighting 3 by battery 5 evening, so just form the solar cell independent lighting system of an a set of family family.

Solar cell independent lighting system of the present invention is more applicable with interior residential building for 5 layers, take five floors as example: 1-5 layer 5 family shared solar cell of corresponding unit house select 24V500W just, automatic control switch and battery are still at each family indoor location.
