1■ Ultra-Weather-Resistant Fluorine Hybrid Powder CoatingKido: Please discuss the context behind development of this product.Tagami: Currently, all manufacturers of street lighting luminaires offer products that exhibit roughly the same performance. Against this background, we worked to develop street lighting fixtures that are more efficient and offer a longer service life than these competing products.Kido: What was the reason for strengthening the base of the pole?■ Ribbed Base with a High Fatigue RatingExtending the Life of Roadway Infrastructure• From the perspective of preventive maintenance, we are extending the life of equipment and reducing Low-carbon Road Construction and Management• Promoting the use of low-carbon construction machinery and materials• Introducing LEDs for street lightingthe frequency of infrastructure renewal, thereby promoting decarbonization.• High EfficiencyDevelopment HistoryThe Ministry of Land, Infrastructure, Transport and Tourism’s Decarbonization Policy in the Road Sector• High Durability• Long LifeUV-resistant fluorine can be combined with other chemicals to form a strong coating. Reducing deterioration over time can decrease the frequency of equipment replacement.Stress is relieved by incorporating corrugations, stress-relief holes, and conical structures. These innovations have contributed to a Grade A fatigue rating.Ryotaro Mainaga, Chief EngineerAkira Tagami,DirectorStreet lighting accounts for about 70% of the electricity consumed in daily road management. The government intends to achieve 100% adoption of LED lighting in all roadway lighting, buildings, and facilities managed by national ministries and government agencies, including existing installations, by 2030.■ LW81 Series High-efficiency Street LightingElectricity costs and CO2 emissions can be reduced simply by revising existing electrical characteristics and adopting appropriate light distribution control measures.At the 73rd Electrical Construction Equipment and Materials Fair known as JECA FAIR 2025, our I-els Long-Life Street Lighting Equipment earned the Chairman’s Prize in the product competition.We spoke with Akira Tagami, Director of Lighting Division, and Ryotaro Mainaga, Chief Engineer of Technology Development Group, about the development process and challenges that were overcome during the development phase for this product.Taro Kido (Moderator): First, please tell us how you became involved in development of I-els Long-Life Street Lighting Equipment.Ryotaro Mainaga: In addition to overseeing the entire group, I ledthe design, analysis, and testing of the base section. In particular,I contributed to improving the durability and strengthen the structure of the base, which is prone to deterioration due to repeated loads from vibration and the like.Akira Tagami: As the project’s overall supervisor, I was responsible for setting specification targets, managing the schedule, and tracking progress.INTERVIEWLong-Life Street Lighting EquipmentWhat We Can Do for YouContributing to Decarbonization Policies in the Roadway Sector
