LED lawn Lights are suitable for green grass beautification lighting in the residential community and beautification embellishment in park lawn.
The system of solar LED lawn lights
The solar LED lawn lights are composed of the solar modules (photovoltaic panels), super bright LED lights (light source), maintenance-free rechargeable battery, automatic control circuit and lamps. The boost IC of solar LED lawn lights can automatically switch to charge and discharge behavior. When solar charging panels are sensitive to the sun during the day, they will automatically switch to turn off the lights and enter the state of charge; when the darkness falls, solar charging panels are not inductive to the sunlight, it will automatically switch to turn on the light and enter the state of battery discharge. Solar lawn boost IC can boost the output voltage of 1.5 volt rechargeable battery to 3.6 volts. A circuit board IC should be equipped with a rechargeable battery that can drive 1-7 LED light-emitting diode; several sets of circuit board IC can be done in the same manner; The main feature of solar Lawn controller integrated circuits as well as some peripheral components contain charging circuit, the driver circuit, the photosensitive control circuit and a pulse width modulation circuit, etc. The controller has a high conversion efficiency: 80 to 85% (typical), which can reduce the power requirements of the solar cell panels; Low start-up voltage: 0.9V (max); adjustable output current.
Light source advantage of solar LED lawn lights
Currently, most lawn lights use LED as the light source. The LED has long life, which can reach more than 100,000 hours; low voltage, very suitable for application in solar lawn lights. LED technology has experienced the key breakthrough, and its characteristics have greatly improved in the past five years, its cost performance has greatly improved. In addition, LED is powered by a low voltage DC, and its light source control cost is low, which makes adjusting the brightness and frequent switching of led honeycomb lightsto become possible, and will not adversely affect the performance of LED. It can also easily control the color; change the distribution of light, resulting in dynamic mirage, so it is especially suitable to be partners on solar lawn lights. Due to the unique advantages of solar lawn lamp, solar lawn light source and power system design methods have developed rapidly in recent years. The lawn light has small power, which is mainly for the purpose of decoration. It has high requirements for mobility, circuit is difficult to be laid, which is applicable to areas with high water-proof requirements. These show unprecedented advantage of solar LED lawn lights powered by solar cells.

Solar lawn lights use the solar cells to work. When the sunlight irradiates on solar cells at the daytime, it turns the light energy into electrical energy and store in the batteries, and then the battery provides power for LED (Light Emitting Diode) lawn lights in the evening. The main advantages are safety, energy-saving, convenient and environmentally friendly. The solar LED lawn Lights are suitable for green grass beautification lighting in the residential community and beautification embellishment in park lawn.
