Fan lights, also known as luxury decorative ceiling fans, are mainly used in European countries and are used as an auxiliary electrical appliance for air conditioners to improve the efficiency of air conditioners. The fan light is beautiful in appearance, equipped with fan blades and lighting of different colors and styles, and has functions such as lighting, cooling, and decoration. In use, the light and fan of the fan light are controlled separately, combining two electrical appliances with different functions. Compared with the traditional ceiling fan, the fan speed of the fan light is lower, the air volume is small, the wind speed is soft, and there is no noise. Its function is mainly to adjust the air flow, which is more suitable for the needs and feelings of the human body. Another feature is that the fan blades of the popular fan lights can rotate in both positive and negative directions, and the reverse function can be used in winter or with air conditioners to promote air circulation. According to experiments, using a fan in an air-conditioned room saves 30-40% of energy compared to not using a fan, and the comfort and ventilation in the room are also greatly improved.
