Carbon nanotubes (hereinafter referred to as CNT) are advanced materials discovered in Japan, characterized by their lightweight, high strength, and excellent elasticity and conductivity, which are being utilized in industrial products. However, CNTs have a tendency to aggregate, making it difficult to uniformly disperse them in resins or liquids. Achieving a stable and uniform dispersion is a challenge to fully realize their original performance. Our company has been developing CNT dispersants based on research results from universities and companies, utilizing our unique polysaccharide extraction technology. We are pleased to announce that we have completed the technological development for commercialization and will begin manufacturing and sales.

Hoshi and Electric Co., Ltd. has been supplying lighting fixtures for numerous roads and tunnels since 1957, when it delivered lighting fixtures for the Kanmon Tunnel, the world's first underwater tunnel at that time. In 2010, it supplied Japan's first LED tunnel lighting fixtures for the Enoura Tunnel, which is under the direct jurisdiction of the Ministry of Land, Infrastructure, Transport and Tourism, continuously leading tunnel lighting in Japan. The newly developed tunnel LED lighting system, the first of its kind in Japan, features a power supply unit installed inside the electrical room, providing direct current to the lighting fixtures in the tunnel. This innovation allows for the miniaturization and lightweight design of the fixtures. While conventional products had the power supply unit within the fixture itself, this new product does not, enabling a reduction in size and significantly easing installation work. Additionally, by consolidating the power supply unit in the electrical room instead of within the fixture, maintenance has been simplified. Recently, we have supplied the tunnel LED lighting system for the Kyuuzan Tunnel (downhill L=1,704m) on National Route 185, under the jurisdiction of the Hiroshima National Route Office of the Chugoku Regional Development Bureau, Ministry of Land, Infrastructure, Transport and Tourism.

In 2010, it supplied Japan's first LED tunnel lighting fixtures for the Enoura Tunnel, which is the first LED tunnel lighting for national highways directly managed by the Ministry of Land, Infrastructure, Transport and Tourism, continuously leading tunnel lighting in Japan. The newly developed tunnel LED lighting system, the first of its kind in Japan, achieves miniaturization and weight reduction by installing the power supply unit inside the electrical room and supplying power to the lighting fixtures in the tunnel with direct current. While conventional products had the power supply unit within the fixture itself, this product allows for miniaturization since the power supply unit is not inside the fixture, significantly reducing installation work. Additionally, by consolidating the power supply unit in the electrical room rather than inside the fixture, maintenance has been simplified. The direct current-powered tunnel LED lighting adopts both the technology registered in the Ministry of Land, Infrastructure, Transport and Tourism's New Technology Information System (NETIS) (CG-170008) and the technology for compact and lightweight LED tunnel lighting fixtures (TH-150008).

The renewal to LED lighting fixtures will greatly change "safety," "energy efficiency," and "comfort"!! The three major benefits of "complete factory LED conversion" proposed by Seiwa Electric are: 1. Improved safety The appropriate replacement period for lighting fixtures is about 10 years. Deterioration progresses to a degree that cannot be judged by appearance alone. Replacing fixtures directly leads to improved safety. 2. Improved energy efficiency LED is the fourth light source following incandescent bulbs, fluorescent lamps, and HID lamps. LED lighting, with its excellent features such as energy efficiency and long lifespan, has a wide range of applications and significantly reduces electricity costs and CO2 emissions. 3. Improved comfort Simply replacing with LED lighting fixtures will completely change the brightness environment. It achieves an efficient and comfortable workplace environment with lighting fixtures suited to the application and purpose.
