FELU Application Field and Working Principle

FELU, an abbreviation for Fiber Laminated Electroluminescent Unit, is a special lighting device used mainly in automotive lighting applications. It uses high-frequency electrical pulses to generate light within a thin flexible layer of polymer film. As a result, FELU devices provide a completely universal and consistent source of light for automotive applications. In addition, they are highly efficient, reliable and cost-effective compared to traditional lighting solutions.

FELU applications include vehicle exterior lighting, such as headlights and taillights, interior lighting systems in passenger compartments and in cargo space, dashboard illumination, and parking lights. They can also be used with radar and navigation systems, trunk and luggage compartment lighting, and in other military and industrial applications. In addition, they have also been used in other areas of entertainment, such as in the theater, television, and in videos.

The working principle of FELU is simple and efficient. It starts with a layer of polymer film placed between the electrodes of a high-frequency electrical signal generator. This polymer layer is the core of the device and contains a special material that is sensitive to electromagnetic radiation, such as ultraviolet and infrared light. The electrical signal generator then applies a series of electrical pulses of increasing intensity until the desired light output is achieved.

Once the pulses are triggered, the material in the polymer film responds by emitting light, which is then directed outward and observed by the naked eye. The intensity and duration of the electric pulses control the brightness and color of the light emitted. Additionally, the color of the light emitted can be varied by changing the frequency of the pulses.

Due to their high efficiency, FELUs have been used extensively in automotive lighting, where they provide excellent luminance, low power consumption, and a much longer life than traditional lighting solutions. Additionally, their flexibility and durability make them one of the most reliable automotive lighting solutions available.

FELU devices are generally considered to be an easy and cost-effective way to improve automotive lighting. The material in the polymer layer is very durable and does not require high maintenance, making them a great option for drivers looking for improved exterior lighting. They are also much easier to install than traditional lighting systems and can often be done by the owner of the vehicle.

Overall, FELUs provide an excellent source of lighting for automotive applications. They are highly efficient, reliable, and cost-effective compared to traditional lighting solutions. Furthermore, they are easy to install and require very little maintenance, making them a great option for consumers looking for improved automotive lighting.
