How many people know the circuit principle of Reflector solar led floodlight? Let's talk about it today. Reflector solar led floodlight is an outdoor light. Instead of relying on a light source for power, solar LED lights use the sun to generate electricity together with a circuit. The solar cell acts as a light source and its output is used to turn on the LEDs. When it gets dark, the output of the solar cell increases and turns off Q1. As the light source voltage drops, the transistor turns on and turns on the LED.

During the day, the solar panels generate the necessary voltage. This voltage is then applied to the rechargeable battery through a diode. To regulate the voltage, you need to set the resistor R* to the specification of the battery. Resistor R* is the current limiting resistor of the LED, usually 10 ohms. The Reflector solar led floodlight lights up when the battery current drops, which is why the battery voltage drops significantly after five or six hours.
Reflector solar led floodlight is made with photovoltaic process that converts sunlight into electricity. Solar energy is captured by polycrystalline silicon photovoltaic modules. When the photoreceptor detects sunlight, it pushes electrons into the positively charged space, and this energy then powers the LED. The battery then stores the energy from the photovoltaic cells to power the LED lights.
The transistors in this circuit generate the pulses that light up the LED. This allows the LEDs to light up when dusk falls. In addition to that, the 1K resistor helps the transistor turn on and produce full brightness on the LED. There are several ways to modify the circuit. The picture above is a simple version of the circuit, but you can use a more complex version. It's important to note that the transistors in the circuit are numbered wrong and the resistors are connected to the emitter.
The ultra-brightness of the Reflector solar led floodlight greatly reduces the cost of solar lighting. In addition, LEDs are long-lived, reliable and do not emit radiation. Therefore, they have the potential to replace traditional lighting. LEDs offer several advantages, such as low operating voltage and energy saving capabilities. LEDs are a great innovation in solid-state light sources. The technology is developing rapidly and has broad application prospects.
This simple circuit works by harvesting solar energy and using it to power a Reflector solar led floodlight. However, higher currents can cause the solar cells to burn out. To avoid this, you need to use a transistor (NPN), which allows current to flow from the solar cell to the base of Q1.
