The role of the various parts:
(1) solar panels: solar panel solar power system is the core part of the solar system, the highest part of the value. Its role is to convert solar radiation to electrical energy stored in batteries or sent to, or promote the work load.
(2) Solar Charge Controller: transistors, resistors, capacitors, inductors form of comparative voltage boost charging and discharging circuit, light control circuit can also be used, or the use of integrated operational amplifier constitutes a voltage comparator hysteresis can also be used microcontroller. Given the general use of the former consider cheap.
(3) Battery: Its role is when there is light energy emitted by the solar panels stored up, and then released when needed.
In addition the design uses a special battery charging management chip UC3906 design solar charge controller, through laboratory testing, its performance to meet the requirements.
Solar energy as a new, first applied in the civilian aspects of the lighting. Currently, in the west light engineering, non-trunk solar lights, solar garden lights and solar lawn lights, solar decorative lights, etc. have been gradually scale. In the design of solar lighting, involving light, solar systems, battery charging and discharging control many factors, any one aspect of the problem will cause a product defect. In this paper, the external characteristics of the solar cell, battery charge and discharge control, solar lighting often makes LED lamps with trichromatic energy efficient comparison and analysis of their respective advantages and disadvantages and the use of the occasion. At the same time on the market for solar lights circuit design problems existing proposed improvements. Since the solar lights that they have unique advantages, in recent years, rapid development. Small lawn lamp power, mainly in the decoration for the purpose of mobility requirements, in addition, the circuit laid difficulties, the high water requirements, so that the above requirements can be powered by solar lawn show many unprecedented advantages. Especially in foreign markets than other solar lawn is a huge demand for the product. In 2002, only Guangdong and Shenzhen for the manufacture of export solar lawn consumes solar cells reach 2MW, was equivalent to a third of the domestic production of solar cells, this year remains strong momentum of development, which is that people did not expect.

The basic PV applications. Here's switch K1 and K3 is charging switch, K3 to discharge switch, they are part of the solar energy control center. The figure by the opening and closing of the switch control circuit according to the charge and discharge status of the system to decide. When the battery is fully charged, the charging switch off when charging is required charging switch is closed; closed when the battery discharge K2, or disconnected. These control circuits can be used transistors, resistors, capacitors, inductors form a voltage comparator boost charging and discharging circuit, light control circuit can also be used, or the use of integrated operational amplifier constitutes a voltage comparator hysteresis can also be used microcontroller.
In general, a qualified solar charge controller has the following charge-discharge protection modes: 1, direct charge voltage protection point: direct charge, also called emergency charge, are fast charging, usually when the battery voltage is low with a relatively high current and high voltage battery charging, however, there is a control point, also known as conservation sites is the values ??in the table, the charging time when the battery voltage is higher than the protection value, stop direct charge. Direct charge protection point voltage is generally "overcharge protection point" voltage, the charging battery terminal voltage can not exceed this protection point, otherwise it will cause overcharge, the battery is damaging.
2, both charge control point voltage: direct charge after the end of the battery can be charged and discharged generally stand controllers for some time, let the voltage drops naturally, immediately fell "recovery voltage" values, will enter all charge state. Why design are sufficient? When the direct charge is completed, there may be individual cells "backward" (relatively low terminal voltage), in order to pull back these individual molecules, so that all the battery terminal voltage has a uniform consistency, so we should take a high voltage with moderate Current refill it a little while, we can see the so-called BC, that is "balanced charge." BC time not too long, usually a few minutes - ten minutes, the time setting is too long but harmful. For small systems equipped with a two batteries are charging little significance. So, lights controller generally does not have sufficient, with only two stages.

Now electricity shortages often blackouts, to people's lives a lot of inconvenience, especially in the summer, an easy power, and the other is very abundant sunshine, so in the evening, you simply do not worry because of power outages and missed homework or other study thing. This lamp can provide long efficient lighting.

(4) Long Life Lamp - Low-voltage low current power supply, light coefficient is much smaller than the fluorescent lamp.

Low power consumption and high brightness LED lights astigmatism high-tech products are environmentally friendly, just a low voltage low current supply can be, it's life 10 times longer than fluorescent lamp, 100 times longer than incandescent.

(5) Low Safelight - low voltage power supply no security risks

9V voltage power supply, there is no problem cause harm inadvertently lamp and other use. Especially active child, even bare hands to touch the lamp inside the wire connectors or sheet metal, nor any of electric shock. Very safe. (6) Environmental

Internally uses a lithium ion battery, in line with the requirements of international environmental conventions, it can be used repeatedly. Use inexhaustible, with the incessant clean energy - solar energy, energy saving and environmental protection, no secondary pollution.

Five of the original selection

1, solar panels choose

Currently photoelectric conversion efficiency of silicon solar cells is about 15%, up to 24%. Is all kinds of solar cells, photoelectric conversion efficiency of the highest, most mature technology. Life in general up to 15A, up to 25A. Polycrystalline silicon solar cells than the photoelectric conversion efficiency of monocrystalline silicon solar cells to reduce the number, the photoelectric conversion efficiency of about 12%, while the polycrystalline silicon solar battery life is also shorter than the monocrystalline silicon solar cells. Amorphous silicon thin film solar cell is low photoelectric conversion efficiency.
