The disclosure relates to the technical field of lighting devices, and more particularly to a solar flame lamp for lawn.
With the development of technology, lighting emitting diode (LED) has more and more applications. The colorful lighting of solar LED lawn lights, courtyard lights and various outdoor lights can make squares, courtyards and other places livelier. Different colors can bring different rendering effects to the surrounding environment.
In addition to the lighting effect, some lamps also have decorative effects. Among many forms of lamps, there is a flame lamp that simulates the jumping and flashing effect of flame combustion. The traditional flame lamp uses a quartz bulb to light up and blow a red silk belt with a fan. The light of the quartz bulb shines on the shaking red silk belt, which looks like a burning flame. However, the fan can bring noise; the silk belt is prone to winding, knotting, damage and other faults. Moreover, the existing flame lamps usually need manual control, which cannot meet the needs of modern automatic control.
In view of this, a main objective of the disclosure is to provide a solar flame lamp for lawn with automatic control, diverse functions, simple structure, low cost, flexible and simple operation, safety and reliability.
