Abstract
The utility model discloses a solar cell lighting system. The solar cell lighting system comprises a solar cell (1), a storage cell (5), a switch (4) and an automatic control switch (2). According to the solar cell lighting system, the solar cell (1) is independent from a power grid and supplies power to an adopted light-emitting diode (LED) direct-current and low-voltage lighting lamp (3) in a direct-current and low-voltage mode through the automatic control switch (2), in day time, the solar cell supplies power to the LED direct-current and low-voltage lighting lamp (3) in direct current and low voltage and charge the storage cell (5) automatically under control of the automatic control switch (2), and at night, the storage cell (5) supplies power to the direct-current and low-voltage lighting lamp (3) automatically. Thus, a set of solar cell lighting system is formed, one-time investment is small, and the solar cell lighting system is more economical and safer than power grid power supply. Even if power failures happen for various reasons, the solar cell lighting system can still grantee normal lighting of units like schools, offices, factories, markets and hotels, and the solar cell lighting system is easy to popularize.
Description
Technical field
The utility model relates to a kind of 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, is 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, developed country is all the more so) situation under convert alternating current to for school with the direct current of solar cell through inverter, office, factory, the market, hotels etc. are household electrical appliance and electric consumption on lighting all, not only disposable input is too high, need just to 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 has a power failure, still can guarantee the normal illumination of units such as school, office, factory, market, hotel in the ordinary course of things, the solar cell illuminator that is easy to promote.
For achieving the above object, solar cell illuminator of the present utility model, include solar cell, automatic control switch, switch and battery, described solar cell illuminator, its solar cell is independent of outside the electrical network, directly powers to the LED dc low-voltage lighting that adopts with low-voltage DC through automatic control switch.
Described solar cell illuminator, solar cell daytime through automatic control switch control to the power supply of LED dc low-voltage lighting and to charge in batteries, then change automatically evening by battery to the power supply of LED dc low-voltage lighting.
Described solar cell illuminator, the rated power of selected solar cell greater than with the rated power sum of LED dc low-voltage lighting.
Described solar cell illuminator, its every LED dc low-voltage lighting is in parallel mutually, and respectively has switch independently to control.
Because solar cell illuminator of the present utility model only needs school, office, factory, the market, units such as hotel LED dc low-voltage lighting power supply, and take the consumer of the electricity overwhelming majority, electrical equipment etc. are still by mains supply, thereby only need select low power solar cell for use, the price of solar cell is 4～5 yuan/watt at present, so contain solar cell, one-time investment such as automatic control switch and battery is fewer, 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, the solar cell illuminator is separated with electrical network in addition, belong to the LED dc low-voltage lighting power supply that safe voltage is given unit by solar cell is independent with dc low-voltage, electricity consumption is safer, even and because of earthquake, tsunami, reasons such as ice damage cause the normal illumination that grid power blackout generally speaking still can guarantor unit, 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, the normal illumination of units such as hotel, the purpose that is easy to promote.
Description of drawings
Below in conjunction with drawings and Examples solar cell illuminator of the present utility model is further described.
Accompanying drawing is the solar cell illuminator of 200 watts in the utility model one cover
1, solar cell 2, automatic control switch 3, LED dc low-voltage lighting 4, switch 5, battery
The specific embodiment
As shown in the figure: 24V, 200 watts of solar cells 1 connect with automatic control switch 2, this cover solar cell illuminator with general power be the LED dc low-voltage lighting 3 (1)～3 (11) of 160W, after parallel connection, connect with automatic control switch 2, it is 10 watts that LED dc low-voltage lighting 3 (1) is selected rated power for use, rated voltage is the bulb of 24V, LED dc low-voltage lighting 3 (2)--3 (11) to select rated power for use be 15 watts, rated voltage is the fluorescent tube of 24V, bulb and fluorescent tube all respectively have switch 4 independent controls, battery 5 also connects with automatic control switch 2, by automatic control switch 2 control realize daytime by solar cell 1 to 3 power supplies of LED dc low-voltage lighting and to battery 5 chargings, it is 24V that battery is selected rated voltage for use, capacity is 100Ah, then change automatically evening by battery 5 and power to LED dc low-voltage lighting 3, so just formed a cover solar cell illuminator.
Solar cell illuminator of the present utility model is more suitable with interior building for 3 layers, for with in the first floor, if it is more to run into LED dc low-voltage lighting requirement, distance is drawn than long place, can be divided into some cover solar cell independent lighting systems controls, in case that principal vertical line decreases is excessive, reduce the supply voltage of LED dc low-voltage lighting, again the burst control during easy access.
Claims (4)
