Automatic Solar Garden Light Circuit Diagram

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.

Automatic solar garden light circuit diagram.

Upgrading to a relay changeover. The solar garden light circuit will consist of two parts. The complete circuit diagram is explained as two parts the first part is given below. In our 4rth automatic solar light circuit we incorporate a single relay as a switch for charging a battery during day time or as long as the solar panel is generating electricity and for illuminating a connected led while the panel is not active.

Using the solar light ic all you need is the solar ic an inductor and the ultra bright led to make the circuit. Potentiometer r1 is used to set the. The circuit is very easy to build using only one transistor and few other parts. 3 7v 2600 mah solar panel cell.

The garden solar light circuit won t work. The drop across the 1n4001 plus the regulator drop across the 7812 regulator ic would require at least 14 5v from the solar panel to charge the battery and maintain the led brightness. Please suggest me the complete circuit diagram of automatic garden solar led light for. In this circuit the 6v solar panel is working as a battery charger and also as a.

Solar garden light circuit diagram. One is charging and the other one is to control the leds. Switches the lamp off at dawn charges the battery during daytime and switches the led lights on at dusk providing 100 lumens illumination during the night. Due to low current battery needs 18 hours to fully charge the battery but sunlight is only available for 12 house max.

N channel mosfet q2 irf540n is used for charge controlling operation. In conclusion at the night time the switching circuit and led light consume 10 to 12w of power from battery and at day time the solar panels refill the battery. The yx8018 comes in a 4 pin transistor style to 94 package and the pin configuration is shown here. Super bright 8mm straw hat 0 5w 3 2v 3 6v 100 120ma x 2 nos.

Circuit diagram of solar garden light. Add the battery and the solar cell and you have a solar light. 4 automatic solar light circuit using a relay. A very useful simple to build automatic solar garden light circuit that is able to serve as a night lamp for your garden or other places.

The yx8018 is more or less just a gated oscillator which runs at approximately 200 khz driving an open drain nmos switch output on pin1. When sunlight falls on the solar cell during daytime the solar cell charges the rechargeable battery and turns led1 off. Solar light ics are very handy they have the dark detection circuit and the voltage multiplying led driver built into one small four pin component. Efficient automatic solar garder lights circuit with minimum components the best deal is that is completely auto and the solar panel acts as a light detector.
