Company Profile
Zhejiang Ledison Optoelectronics Co., Ltd. was founded to fuse new technology with retro fashion to create amazing new lighting experiences. Ledison operates a highly focused lighting business and has built a compelling technology portfolio that makes the company as sparkling as its flagship lighting solutions - LED filament bulbs. Located in Hangzhou, China, Ledison Optoelectronics is a young company backed by long-standing research from a retired Zhejiang University professor, Ge Shichao, and his team. It is this team that has built one of the world's most complete patent portfolio for LED filament bulbs, among the well-known industry players such as Epistar, Nichia, and USHIO.

Since its incorporation in 2011, Ledison Optoelectronics has made significant strides in the commercialization of its technology. The company built its own facilities to encapsulate LED filaments and produce LED bulbs. Ledison's filament technology features an industry-leading efficiency (as high as 175 lm/W) and excellent color rendering index (CRI Ra 95). Ledison's LED filament bulbs are made in a variety of glass shapes that provide a bold and bright atmospheric statement and capture the attention of lighting designers. These extremely decorative and utilitarian GLS, candle, golfball, and creatively shaped LED bulbs are ideal for use in chandeliers, ceiling lights, pendant lights, and designer light fixtures to create a pleasant ambiance in a range of locations such as fine-dining restaurants, hotels, hospitality environments and residential spaces.

The relentless research and development yield an impressive breadth and depth of invention, reflected in Ledison's intellectual properties. The company's LED filament patents cover jurisdictions including China, US, Europe, Japan, Canada, Australia, and other countries and markets in both advanced and emerging economies. The comprehensive IP portfolio laid a solid foundation for the company to expand globally with the powerful patent shield. In addition to in-house production, Ledison also licenses its technology to other lighting manufacturers including Zhejiang Klite Lighting Holdings Co., Ltd. and Sunny World (Shaoxing) Green Lighting Co., Ltd.
