Lighting function: It is equipped with various types of light sources, such as LED lamp beads, etc., which have the advantages of high brightness, low energy consumption, and long lifespan. Some ceiling fan lights also feature a three - color light - changing system or stepless dimming function. According to different scenarios and needs, users can freely adjust the color and brightness of the light to create different atmospheres, such as warm, romantic, and bright ones.Cooling and Ventilation: The rotation of the fan generates an air current, accelerating air circulation, which helps to reduce the temperature and relieve the heat. It can bring a cool breeze indoors during hot summers. Moreover, it can promote the circulation of hot air, making the indoor temperature more even and enhancing comfort.Energy - saving and power - saving: Compared with using an air - conditioner alone to adjust the indoor temperature, the energy consumption of a ceiling fan light is much lower. When the temperature is not extremely high, using a ceiling fan light can meet the cooling needs, reducing the frequency of using the air - conditioner, thus achieving the goal of energy - saving and power - saving.
