Abstract

The invention discloses a solar cell lighting system. The solar cell lighting system comprises a solar cell (1), a storage battery (2), an automatic controller (3), an inverter (4), an air switch (5), a unit main switch (6), and a switch (8), wherein the solar cell (1) is independent of a power grid and provides direct current to indirectly supply power for light-emitting diode (LED) lighting lamps (7), the solar cell (1) indirectly supplies power for the LED lighting lamps in each lighting unit and charges the storage battery (2) in the daytime, and at night, the storage battery (2) is automatically switched to supply power for the LED lighting lamps (7). According to the solar cell lighting system, the solar cell lighting system for a building is formed, small one-time investment is achieved, the solar cell lighting system is more economical and safe by comparison to mains supply, even if power is cut due to various reasons, normal lighting of an institution can be still guaranteed in a general condition, and the solar cell lighting system is easy to popularize.

Description

Solar cell illuminator

Technical field

The present invention relates to a kind of 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 family through inverter, school, office, factory, market, whole consumers 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 good selection, so this pattern is in the world also just for some exemplary engineerings, promote and just become difficulty.

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 family, school, office, factory, market, hotel, be easy to the solar cell illuminator of promoting.

For achieving the above object, solar cell illuminator of the present invention, include solar cell, battery, automatic controller, inverter, air switch, unit master switch, switch, described solar cell illuminator, its solar cell is independent of outside electrical network powers to the LED lighting adopting indirectly with direct current.

Described solar cell illuminator, solar cell connects the input of automatic controller with direct current output, battery connects another input of automatic controller, the input of the output termination inverter of automatic controller, solar cell daytime through automatic controller control by inverter to the LED lighting power supply of each floor and to charge in batteries, automatically turn by battery and power to the LED lighting of each floor by inverter through automatic controller control evening.

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

Described 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 LED lighting of each lighting unit, each lighting unit has unit master switch control, lighting unit every LED lighting parallel with one another, and respectively have switch independently to control.

Due to solar cell illuminator of the present invention, only need be to family, school, office, factory, market, the LED lighting power supply of the units such as hotel, and the consumer 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, thus fewer at interior one-time investment containing solar cell and battery etc., can comparatively fast recoup capital outlay, solar battery life is 20 years, the period being equivalent to is thereafter not need the flower electricity charge substantially, than more economical by mains supply, because electric consumption on lighting separates with electrical network, 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 family, 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, solar cell illuminator of the present invention is further described.

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

1, solar cell 2, battery 3, automatic controller 4, inverter 5, air switch 6, unit master switch 7, LED lighting 8, switch

As shown in the figure: 32 floor rooms of certain unit, the total specified power designs of its all LED lightings 7 is 20KW to the maximum, consider 20% surplus, selecting rated power is 25KW, rated voltage is the solar cell 1 of 48V, solar cell 1 connects with the input of automatic controller 3, battery 2 connects with another input of automatic controller 3, the output of automatic controller 3 connects with inverter 4 inputs, 48V direct current is converted to the output of 220V alternating current by inverter 4, its rated output power is 20KW, the 220V alternating current output main line of inverter 4 is respectively to the each lighting unit power transmission from 32 layers of ground floors to the, taking the 32nd layer as example: export main line lead-in wire from inverter 4 and connect with the inlet wire of the air switch 5 of the 32nd layer, the outlet of air switch 5 connects respectively the LED lighting 7 of each lighting unit, each lighting unit has master switch 6 to control, lighting unit has the LED lighting 7 that a n rated voltage is alternating current 220V, n small cup LED lighting 7 is parallel with one another, and respectively there is the independent control of switch 8, the mode of connection of each lighting unit is identical, control to turn by battery 2 through automatic controller 3 and power to LED lighting 7 by inverter 4 evening, in order to ensure above power supply in continuous 12 hours, battery is selected 48V, 6500AH's, so just form the solar cell illuminator in the Yi Dong of a unit building.
