In our daily life, the application of solar energy is becoming more and more widespread. From solar power generation to solar rice cookers, various products are on the market. Among the many applications of solar energy, we have to focus on the various applications of solar LED lighting.
Solar cells and LED lighting are typical applications of new energy and energy-saving and efficient technologies. Solar LED lighting uses solar cells to convert solar energy in nature into electrical energy and provides it to LED light sources. Due to the low-voltage, energy-saving and long-term characteristics of LED light sources, the application of solar LED lighting systems will achieve high energy utilization efficiency, work reliability and practical value. Common applications now include solar LED lawn lights, solar LED street lights and solar LED lighting.
The working principle of the solar LED lighting system is: in the period of time when there is sunlight, the solar battery pack converts the collected solar energy into electrical energy, and under the control of the control system, the solar photovoltaic cell MPPT method is used to store the electrical energy in the battery pack , when the LED lighting system needs power supply, the PWM control drive mode is used to provide safe and efficient voltage and current to the LED lighting source, so that the LED lighting system can work safely, stably, efficiently and reliably, and provide clean and environmentally friendly green for work and life illumination.
Today, as clean energy is becoming more and more important, the status of solar energy is becoming more and more prominent. Solar energy is the most direct, common and clean energy on the earth. As a huge amount of renewable energy, the radiant energy reaching the earth’s surface every day is about 250 million barrels of oil, which can be said to be inexhaustible and inexhaustible. exhaust. The spectrum of LEDs is almost all concentrated in the visible light frequency band, so the luminous efficiency is high. Most people think that energy-saving lamps can save energy by 4/5. reform.
Solar LED lighting integrates the advantages of solar energy and LED.
