LED solar lawn light technology principle

LED solar lawn light technology principle:

Taking sunlight as energy source, LED light emitting diode as light source, stable color light, no flicker, shockproof, environmental protection, no need of external power supply, charge and turn on/off light process controlled by microcomputer intelligently; automatically turn on the light in darkness, automatically turn off the light in daylight, no need Manual operation, stable and reliable work, long service life, safety, energy saving and no pollution. It is best suited for urban citizens' plazas, urban parks, and lighting and decoration around buildings with modern environmental awareness. Especially in the power-hungry cities, the advantages of energy-saving and no-grid power are favored.

Product Overview:

The solar lawn lamp mainly uses the energy of the solar cell to work. When daytime sunlight shines on the solar cell, the light energy is converted into electricity and stored in the battery, and then the battery is provided for the lawn light LED (light emitting diode) at night. power supply. The solar lawn lamp boost IC can automatically switch between charging and discharging behaviors. When the solar charging board senses sunlight during the day, it automatically switches to turn off the light and enters the charging state. When the night-time solar energy charging board cannot sense sunlight, , automatically switch to enter the battery discharge state to turn on the lights.

The solar lawn boost IC can raise the output voltage of the 1.5 volt rechargeable battery to 3.6 volts. A set of circuit board ICs should be equipped with a rechargeable battery No. 5 can drive 1--7 LED light-emitting diodes; multiple sets of circuit board ICs and so on; its advantages are mainly safe, energy-saving, convenient, and environmental protection. The solar lawn light controller is specially customized by our company according to the characteristics of the solar lawn lamp. It contains a special integrated circuit (6601D) developed by our company and some external components.

The main functions include charging circuit, driving circuit, photosensitive control circuit and pulse width modulation circuit. The controller has high conversion efficiency: 80~85% (typical), which can reduce the power requirements of solar cell boards; low start-up voltage: 0.9V (maximum); adjustable output current and other characteristics.
