Solar lawn lamps are new, environmentally friendly and decorative. They use imported monocrystalline silicon or polycrystalline silicon solar battery components to absorb sunlight for power generation. During the daytime they charge automatically and give light automatically at night (charging and lighting are controlled by light). The lamps use a variety of materials and the lights may assume a number of colors. Light source uses LED lamp, low-voltage sodium lamp and efficient energy-saving lamp. Solar lawn lamps use Ni-Cd, Ni-MH or maintenance-free battery. Fully charged battery may give light for 20-50 hours on-end and it can be used normally during 2-5 rainy or cloudy days. The lamps are mainly applied to decorative lighting in parks and squares, housing estates, villas and street spots.
