The Evolution of Light · The Freedom of Illumination

Throughout history, humanity’s pursuit of light has taken ever-evolving forms. The advent of portable lighting has elevated this journey to new heights—offering freedom, flexibility, and unparalleled convenience. Lightweight, intelligent, and long-lasting, it has become an essential companion in navigating the unknown and expanding possibilities. Portable lighting embodies the deep-rooted desire for “light that moves with you,” illuminating not only the path ahead but also reflecting the warm integration of technology and human-centric design.

TYF specializes in developing LED lighting solutions for specialized applications. We proudly introduce our high-power light source for portable lighting, which utilizes advanced high-thermal-conductivity ceramic packaging. This innovative design ensures superior heat dissipation, high luminous efficacy, and an excellent beam pattern. Available in 3535, 5050, and 7070 standard sizes—in both domed and flat options—for seamless optical integration, it is ideally suited for high-performance flashlights, headlamps, work lights, and automotive lighting systems.
