Why solar light need circuit?
Many competitors had contacted us about our solar light products and one of the topic they are interested is the circuit for solar light. Therefore, below article explains: Circuit 1Both Solar Garden Light circuits in this article perform 2 functions: 1. They charge a battery and 2. Turn on a high-bright white (or yellow) LED at dusk and off during daylight hours. The two circuits are completely different in design and we will see how different designers tackle the same problem. Firstly we will discuss the circuit above. It is called Circuit 1. Here’s the clever part: The circuit doesn’t deliver a DC voltage to the LED but a high-frequency pulse. This creates the same brightness from the LED (as a constant DC voltage) while needing less than 50% of the energy. It also allows a single cell to be used. Also, the circuit does not have a dropper resistor for the LED and this further increases the efficiency. The third clever idea is the use of a single rechargeable cell – even though the w
