The working principle of fan lights

an lights are home devices that combine the functions of fans and lighting fixtures. It not only provides comfortable wind power, but also lighting, becoming an indispensable part of modern homes. So, how does the fan light work? Below, we will provide a detailed introduction to the working principle of fan lights.
一、 The working principle of the fan section
The fan part is the core component of the fan light. It adopts the principle of electric motor driven blade rotation to generate airflow. Generally speaking, fan lights use AC power as the power source.
1. Electric motor
The electric motor for fan lights usually uses an induction motor or an electromagnetic motor. Induction motors are mainly composed of stator, rotor, and fan blades. When AC electricity passes through the stator winding to generate a magnetic field, the induction effect of the rotating magnetic field generates an induced current inside the rotor, thereby generating torque to drive the rotor to rotate.
2. Fan blades
Fan blades are usually composed of several blades, and their material is usually plastic or metal. When the electric motor drives the fan blades to rotate, local airflow is generated by the friction between the blades and the air, forming wind force.
3. Wind power regulation
Fan lights usually have multiple wind speed regulation functions to meet the needs of different situations. By controlling the driving force of the electric motor, the speed of fan blade rotation and the intensity of airflow can be adjusted.GS2253-01
二、 Working principle of lighting fixtures
The lighting fixture is another important component of the fan light. It provides lighting functions through light bulbs or LED light sources.
1. Light bulb
The bulbs used in traditional fan lights are usually incandescent bulbs or energy-saving bulbs. When the fan light is powered on, current flows through the wires of the light bulb, causing the filament to heat and emit light.
2. LED light source
In recent years, with the development of LED technology, more and more fan lights have started to use LED light sources. LED has the advantages of high efficiency, low consumption, and long lifespan, making fan lights more energy-efficient and environmentally friendly.
3. Lighting adjustment
Fan lights generally have the function of lighting adjustment, which can be controlled by devices such as switches or remote controls to adjust the brightness of the lighting. By adjusting the resistance, capacitance, and other components in the circuit, the magnitude of the current can be changed to achieve the adjustment of lighting brightness.
三、 The working principle of the circuit part
The fan and lamp parts of the fan light are connected through circuits to achieve various functions.
1. Power supply
Fan lights are usually connected to an AC power supply, with a voltage typically of 220V or 110V. The power supply is responsible for converting AC power into DC power suitable for the normal operation of the fan lights.
2. The wind speed and lighting regulation of the circuit controlled fan lights are usually achieved through circuit control. Circuit control can control the on/off of current through switches such as relays and transistors, thereby adjusting the speed of the fan and the brightness of the lighting fixtures.
3. Protective devices
The circuit of fan lights is usually equipped with various protective devices to ensure the safety and reliability of the fan lights. Common protective devices include overcurrent protection, overheating protection, and short circuit protection.
Summary:
The fan light is driven by an electric motor to rotate the fan blades, generating airflow and providing comfortable wind power. Meanwhile, lighting functions are provided through light bulbs or LED light sources. The circuit part is responsible for converting AC power into DC power suitable for the operation of fan lights, and regulating and controlling wind power and lighting. During use, protective devices are also equipped to ensure the safety of the fan lights. The above is a detailed introduction to the working principle of fan lights, hoping to be helpful to everyone.
