Why are LED solar lawn lights popular?

Solar lawn lights are energy-saving and environmentally friendly, and can light up night life, and are loved by the general public. The layout of the LED solar lawn light is composed of solar cell components (photoelectric panels), ultra-bright LED lights (light source), protection-free rechargeable batteries, active control circuits, lamps, etc. The system composition of the LED solar lawn light: The solar lawn light booster IC can actively switch the charging and discharging actions. When the solar charging panel senses sunlight during the day, it will automatically switch to the closed light and enter the charging state. When the night comes, the solar charging When the board does not sense sunlight, it will automatically switch to enter the battery discharge state and turn on the lights. The solar lawn light boost IC can boost the output voltage of a 1.5 volt rechargeable battery to 3.6 volts. A set of circuit board IC should be equipped with a 5th rechargeable battery to drive 1--7 LED light-emitting diodes; multiple sets of circuit board ICs and so on; the integrated circuit of the solar lawn lamp controller and some edge components, The primary functions include charging circuit, driving circuit, photosensitive control circuit and pulse width modulation circuit, etc. The controller has the characteristics of high conversion power: 80~85% (typical value), which can reduce the power demand of the solar cell version; low dynamic voltage: 0.9V (maximum value); adjustable output current. The light source advantages of LED solar lawn lights: At present, most lawn lights use LED as the light source. The LED has a long lifespan, which can reach more than 100,000 hours, and the operating voltage is low. It is very suitable for use in solar lawn lights. In particular, LED technology has now achieved its key breakthrough, and its characteristics have greatly improved in the past 5 years, and its performance-price ratio has also greatly improved. In addition, the LED is powered by low-voltage DC, and its light source control cost is low, making it possible to adjust the light and dark, and to switch frequently, and it will not adversely affect the function of the LED. It can also easily control the color, change the light distribution, and generate dynamic illusions, so it is especially suitable for solar lawn lights. Due to the unique advantages of solar lawn lights, the lighting source and power system description methods of solar lawn lights have developed rapidly in recent years. The lawn lamp has low power and is mainly intended for decoration. It is suitable for places with high requirements for mobility, difficult circuit laying and high waterproof requirements. These make lawn lights powered by solar cells show many unprecedented advantages.
