Efficient and versatile four direction LED-based automotive lighting systems advances in optical modeling and performance predictions

Existing tail surface lighting technology is expensive and only irradiates LED light from the front, requiring multiple optical parts and air gaps for effective light diffusion. The 4FLED technology, which stands for "4 Faces LED," offers a cost-effective solution by providing 360-degree light irradiation from four directions. This reduces the need for additional optical parts and spaces, saving costs. Two wavelengths, normal red (614 nm) and super red (630 nm), are available, offering expanded choices for customers. The 4FLED system aligns with global design trends by reducing costs while maintaining high efficiency and design flexibility, appealing to many customers. It has been proven suitable for vehicles through ECE Regulation tests and high heat resistance reliability tests.
