Solar Powered Led Street Light With Auto Intensity Control
Solar panel battery charger circuit diagram for street lighting. The smd leds are fully safeguarded thermally and from over current using an inexpensive lm 338. The transistor is the only active component which is positioned as a switch for preventing the battery voltage from reaching the connected leds during day time. Unlike other circuits we will not be using a microcontroller or sensor because the idea of the project is to reduce the component count to reduce the price and complexity of the circuit. Here is a solar charger circuit that is used to charge lead acid or ni cd batteries using the solar energy power. Solar panel forms the backbone of the above circuit. The circuit harvests solar energy to charge a 6 volt 45 ah rechargeable battery for various applications.
Here is the simple solution to make an automatic solar powered led lamp. Best solar panel for charging 12 volt battery is perfect for portable off grid systems such as small cabins rvs sheds car and boats. The 3rd idea teaches us how to build a simple solar led with battery charger circuit for illuminating high power led smd lights in the order of 10 watt to 50 watt. Add the battery and the solar cell and you have a solar light. Built a solar panel array putting out 12 14v and about 34ma to charge a 9v 300mah battery. Circuit diagram of solar garden light.
As it requires ladder to change out battery. Best 12v battery solar charger. It automatically switches on two high power white leds in the evening and stays on for 6 hours using a 6 volt 45 ah rechargeable battery. This circuit requires only a single ni cd rechargeable battery to light up the white led for more than five hours depending upon the ampere hour ah capacity of the battery. As can be seen in the given circuit diagram the design basically consists of a solar panel a pnp transistor few leds a battery and a few resistors. Best 12v battery solar charger panel typically put out about 136v to 170 volts use to charge 12v battery or to run any 12v devices.
A 12 volt solar panel is used to charge the battery during day time. The solar panel will charge a lithium battery during day time and when it becomes night time the battery will turn on the lights until its day time again. The above circuit can be classified into two sections charging section from panel to battery and lighting section from battery to leds. When sunlight falls on the solar cell during daytime the solar cell charges the rechargeable battery and turns led1 off. Using the solar light ic all you need is the solar ic an inductor and the ultra bright led to make the circuit. The charging section serves the purpose of charging the battery whereas lighting section powers up the leds connected to it.
Using converter you can charge mobile also.
