Recently, with the professional technical support provided by Suzhou Arnool testing and certification Co., Ltd., Edison successfully obtained the ZHAGA-D4i Book 18 certification for its LED streetlights. This marks another milestone in Edison’s breakthroughs in the lighting industry, enabling the company to compete on equal footing with renowned domestic and international enterprises.


The ZHAGA Alliance is an open organization; its name, “ZHAGA,” is said to be a direct transliteration of “Zhaga,” the name of a waterfall in Sichuan, China, and has no specific meaning. All members of the alliance can share intellectual property rights (IPR), and membership is open to various companies in the lighting industry. Consequently, the organization’s membership includes LED light engine manufacturers and LED luminaire producers, as well as component suppliers (such as heat sinks and optical components). Currently, the alliance has 162 corporate members, primarily from Europe, Asia, and North Africa. TRIDONIC is one of the ZHAGA Alliance’s key members.
Headquartered in Europe, the ZHAGA Alliance is an organization dedicated to establishing standards for LED light engine products and developing standardized interfaces for them. Its mission is to achieve interoperability among lighting fixtures from different manufacturers that use products based on ZHAGA standards. Furthermore, to keep pace with the continuous and rapid development of LED technology, the ZHAGA standards cover key areas such as physical dimensions, optics, electrical specifications, light distribution, and thermal management. Ultimately, this ensures that products from different manufacturers within the ZHAGA Alliance are compatible, interchangeable, and replaceable. Therefore, while national LED regulations and standards focus on performance and quality (such as lifespan, energy efficiency, color temperature consistency, etc.), the ZHAGA Alliance addresses the issue of interchangeability among manufacturers.
Furthermore, the establishment of the ZHAGA standards will help prevent market fragmentation caused by incompatible light engine products, allowing LED luminaire manufacturers to confidently purchase compatible LED light engine products on the market. Furthermore, the establishment of ZHAGA standards promotes technological innovation in the field of LED lighting applications, enhances the overall efficiency of the LED lighting industry, and contributes to a standardized and orderly LED lighting market.

Edison Optoelectronics Co., Ltd. was founded in 2001. From its inception, the company focused on LED lighting as its primary product, becoming a pioneer in Taiwan’s lighting industry. Since its establishment, it has gradually expanded its product portfolio to include components, automotive lighting, AC modules, horticultural lighting, and streetlights, with the aim of broadening its market reach and building a kingdom of integrated lighting and design services. To establish a systematic module production system, Edison Opto created a Thermal, Electrical, Mechanical, and Optical (TEMO) technology and design service platform to enhance product quality and pioneered design services such as lighting integration: LDMS (Lighting Design Manufacturing Service) covers everything from component to module design, and from optical lens applications to finished product development. This vertical manufacturing integration and design solution has opened up new markets and enabled the company’s products to reach a global audience. To date, Edison has gradually expanded its operations from its headquarters in Taipei, Taiwan, to Dongguan and Yangzhou in China, and has established a subsidiary in California, with business operations now spanning the globe. With Taiwan and China as its primary product export hubs, Edison continues to illuminate Europe, the Americas, and the rest of the world.
