Solar street lamps to how to design

With the continuous development and some basic resources of the human abuse, now left fewer and fewer resources on earth. In this case, the use of solar energy technology is produced. Solar energy can not only an inexhaustible, inexhaustible, and no pollution to the environment. Solar energy lamps and lanterns is not only save energy and has no pollution to the environment. It these features in more and more wide, popular among people, solar technology in the application of street lamp has been increasingly perfect, here to talk about a common seen is how to design the solar street lamps.

1, the controller of solar street light it is utilizing sunlight in the daytime storage power, releases energy from the battery to power again in the evening. Solar street light control circuit mainly has four parts, consist of battery, controller, photovoltaic cells, street lamp. In the circuit for AT89S52 single chip microcomputer intelligent core module. Battery voltage sampling module, charge and discharge control module, keyboard circuit module, the solar battery voltage sampling module, LED display module and so on constitutes the external circuit of solar street light.

2, power supply circuit of solar street light will make the power supply voltage of 5 v can work normally, generally USES the power supply voltage of 12 v or 24 v three yuan in battery powered, sometimes the supply voltage is not very stable, so you need to take some measures to stabilize voltage. Voltage regulator can be used to maintain voltage stability.

3, sample template design can run normally, solar street lamps mainly depends on the solar cell sampling and storage battery samples. Controller in the system, if you want to, want to battery charging and discharging is normal, need to apply to the battery and solar cell samples, so you need to use single chip voltage is converted to digital. In sampling template design to ensure the system does not crash or other accident, need to add a single channel of high-speed optical isolator, to maintain the stability of the system.

the design of the solar street lamps, will directly affect the quality of solar street light, so in each part to carry on the design, components selection is crucial.
